county economy

The booming rural economy

Huanxian county has always been a big agricultural county, and the rural economy plays an important role in the county's economic structure. 1983 was identified as a semi-agricultural and semi-pastoral county by the provincial party Committee and government. In recent years, the county party committee and government have adhered to the policy of "laying a solid foundation, highlighting characteristics, giving full play to advantages, and becoming bigger and stronger", with the goal of increasing farmers' income, intensified the adjustment of agricultural structure, vigorously developed the three characteristic industries of grass and livestock, potatoes and miscellaneous grains, and expanded the regional advantageous industries such as oil, medicinal materials, seedlings, apricots, yellow flowers and pepper; With the goal of strengthening the development potential, the construction of farmland water conservancy and ecological environment has been accelerated, which has promoted the all-round development of rural economy.

The leading industry is unique.

Animal husbandry is a traditional industry around the county, and one third of farmers' economic income comes from animal husbandry. In recent years, although animal husbandry in Huan County has made some progress, due to the influence of traditional ideas, the problem of grassland degradation caused by overgrazing is very prominent, and the contradiction between grass and livestock obviously restricts the rapid development of animal husbandry. In this regard, through careful investigation and study, Huan County put forward the development idea of establishing a career with grass and promoting animal husbandry with grass, taking the development of grass and livestock industry as the first leading industry to revitalize the rural economy and increase farmers' income, and making great efforts to implement the development strategy of a county with large grass and livestock and a county with strong animal husbandry. During the period of 1999, the county set up a leading group for the development of grass and livestock industry, and issued the Implementation Plan for the Construction of a Million Mu Alfalfa Base in Huanxian County, fulfilling the target responsibility. In the specific implementation, combined with the implementation of the project of returning farmland to forest (grass), we will focus on planting professional grass, engineering grass, excellent grass and industrial grass, pay close attention to implementation, and do everything possible to raise funds to support livestock farmers. Since 2000, it has invested more than 3 million yuan every year. In the past four years, 510.6 million mu of alfalfa has been planted, 30,200 square meters of sheep and livestock sheds have been built in 960 places, 9 10 silage pits have been set up, 9 10 ammoniation tanks have been set up, and 2,600 excellent varieties have been introduced, which has developed1. Tianchi Township has planted 47,700 mu of perennial pasture in the past three years, with an average household size of 59 mu, taking the lead in becoming the "10,000 mu demonstration township for planting grass and raising livestock" in the county; Gaozhaigou Village in Mubo Town has set aside 300 mu of Sichuan water land to grow alfalfa and developed 86 farmers, becoming the "leading" village in the county. There are 220 households in the county, and each household grows more than 20 mu of perennial grass. By the end of 2002, the county had planted 796,000 mu of perennial pasture, including 766,000 mu of alfalfa, with an annual output of 4 million tons of pasture and 6,543,800 kilograms of alfalfa seeds. The number of livestock raised reached 6.5438+0.2 million, the number of sheep raised reached 720,000, and the number of large-scale farmers reached 6.5438+0.2 million. There are 300,000 sheep and livestock in the county every year, with a total output of 6.5438+200,000 tons of sheep and livestock meat, a total output value of 68.65438+600,000 yuan of animal husbandry and a per capita net income of 360 yuan.

The development of grass and livestock industry has led to a number of promising leading enterprises. At present, Lv Xin Grass Industry Development Co., Ltd. has been completed and put into production, and all kinds of animal products produced by Jin Peng and Hua Mao Meat Food Co., Ltd. are favored by consumers and have good market prospects. During the Tenth Five-Year Plan period, it is planned to plant more than 200,000 mu of perennial forage mainly alfalfa. By 2005, the area of perennial pasture in the county will reach 6,543.8+0,000 mu, and the number of sheep and livestock will reach 6,543.8+0./kloc-0.5 million. According to the animal husbandry development layout of "North Sheep, South Cattle and Yanchuan Pig", we will build four bases, namely, 300,000 cashmere goats in seven towns in Northeast China, 50,000 tan sheep in eight towns in Northwest China, 6,543,800 beef cattle and mutton sheep in ten towns in Central South China and 50,000 lean pigs in six towns along Sichuan. By 2005, the grass and livestock industry will strive to provide farmers with per capita net income above 700 yuan. Support the establishment of grass and livestock industry processing enterprises 10, with an annual output value of 654.38 billion yuan and profits and taxes of 20 million yuan.

The loess layer of potato industry in Huanxian county is deep, the soil is loose and fertile, and the air permeability is good. It has unique natural conditions for planting potatoes, and the produced potatoes have the characteristics of no pesticide pollution, no mildew, no deterioration, long storage period, storage resistance and so on, occupying a broad market. Huanxian county seized this advantage and regarded the development of potato industry as another leading industry to revitalize the rural economy and drive farmers out of poverty and become rich and well-off. A coordination leading group was set up, a development plan was formulated, and practical and effective service measures such as financial support, introduction of improved varieties and scientific and technological training were taken, which mobilized the enthusiasm of farmers to grow potatoes. The planting scale is expanding year by year, and the economic benefit is very obvious.

In 200 1 year, according to different regional conditions, the county determined that the northern part of the county was a high-starch potato producing area, the southern part was a vegetable potato producing area, and the central and southern part of the county was a vegetable producing area with a short growth period. About 400,000 mu is planted throughout the year, with an annual output of 200 million kilograms. Six towns, such as Sweet Water and Shancheng, plant more than 20,000 mu a year, 12 towns.

In order to do a good job in seed breeding, storage and processing, Huanxian has built the only virus-free seed potato breeding center in Qingyang-Quzi High-tech Demonstration Park, and built 55 acres of all-steel insect-proof net rooms in the park, Mengjiazhai Village in Quzi Town and Mubojie Village in Mubo Town. Establish a 100 mu first-class potato seed base in Tianshui Street Village, Tianshui Town; We will build 20,000 mu of secondary seed potato bases in Fengtai Village, Baiyuanpan Village, Siheyuan Village and Kecun Village, Huang Zhai, Maojing Township in mountainous areas, with an annual output of 6.5438+million kilograms of excellent seed potatoes. Five large potato storage warehouses with a storage capacity of 5,000 tons and 2,000 tons were built in Quzi, Shancheng and other towns, with an annual storage capacity of 30 million kilograms of fresh potatoes. Established Jindibao Potato Fine Powder Co., Ltd. to support the establishment of five small processing plants with an annual processing capacity of more than 60,000 tons.

With the acceleration of national industrial structure adjustment, potato industrialization has become the most competitive emerging industry in the west. After extensive market research, Huanxian plans to build Gansu Xinghuan Potato Development Co., Ltd. with an annual output of 4,000 tons of potato starch, and adopt a new three-dimensional economic development model of integration of planting, processing and marketing, integration of agriculture, industry and commerce, and "company+farmers" to achieve a double harvest of economic and social benefits.

Small coarse cereals industry Huanxian County has a long history of planting all kinds of small coarse cereals with diverse varieties and unique quality. Every year, 20 kinds of minor cereals such as buckwheat, millet, millet, corn, mung bean, pea, oat and tartary buckwheat are planted, covering an area of about 300,000 mu, with a total output of more than 3 million kilograms. With the continuous improvement of people's living standards, the development prospects of small grains such as buckwheat, oats and millet, which are famous for their health care and green food, are getting broader and broader. Buckwheat in Huanxian contains many nutrients, especially rutin and nicotinic acid. It is an auxiliary drug for the treatment of hypertension, the first choice of health food for diabetic patients, and has important medicinal value. Millet contains a variety of fatty acids and vitamins, which has the functions of nourishing kidney and stomach, quenching thirst and relaxing bowels; Beans and miscellaneous grains such as peas, lentils, mung beans and adzuki beans contain 10 amino acids and various trace elements necessary for human body. Long-term consumption can clear away heat and toxic materials, diminish inflammation and swelling, lower blood pressure and prevent arteriosclerosis. Based on the above understanding, Huan County put forward a new idea of "expanding summer and autumn and miscellaneous grains", and put small miscellaneous grains as a characteristic industry on the important agenda, and actively organized and implemented it.

The first step is to adjust the planting structure and increase the planting area of minor grains. In the northern part of the county with vast land, the crop area in summer and autumn has been adjusted from 6:4 to 4:6, of which minor grains account for 50% of the grain crop area. 1999-200 1, a severe drought occurred in Huanxian county, which led to a large-scale reduction of wheat production and no harvest. Thanks to the remedial measures of small autumn decisive battle and small miscellaneous grains decisive battle, 2.3 million mu of small miscellaneous grains planted in the county for three years have achieved a bumper harvest, with an average yield per mu of 100 kilograms, effectively curbing the situation of grain production reduction and rural economic decline. In the year of drought, the fact that small grains were harvested educated the cadres and the masses. Therefore, the county party committee and the county government took advantage of the situation and put forward the grand goal of implementing the project of one million mu of small miscellaneous grains. In order to make the project go smoothly, the county tried every means to introduce and cultivate excellent varieties suitable for local cultivation, promote them from small plots to fields, draw agricultural technicians to the fields for technical guidance, and rural cadres went to the village to implement them and contact the market as soon as possible. In 2002, with the help of heaven and the efforts of people, 65.438+0 million mu of small miscellaneous grains enjoyed a bumper harvest, and the total output reached 65.438+0.2 billion kg, a record high. Only this one, the per capita income of farmers increased by 225 yuan. The bumper harvest of minor grains not only satisfies the grain hoarding of farmers, but also urges a group of new farmers to go out of the land and become transportation and marketing households, which not only facilitates the masses, but also becomes the leading role for farmers to go to the market.

In order to obtain better economic benefits for the minor grains industry, the second step taken by the county is to raise funds by all means to set up minor grains deep processing enterprises. At present, the established enterprises include Tianshui Longfei Co., Ltd. with an annual output of 1.500 tons of "Tianlong" brand buckwheat noodles; Huanxian Xinrong Food Industry Co., Ltd. has an annual output of 650 tons of "brand" vinegar and Joe dried noodles; Huanxian Xintai Coarse Grains Industry and Trade Co., Ltd. has an annual output of 550 tons of "Rainforest Brand" pea powder series products; Gansu Baiyi Industrial Co., Ltd. has an annual output of 400 tons of Baiyi brand yellow wine and liquor series products; Changfeng Cereals & Oils Industry & Trade Co., Ltd., with an annual output of "five grains", has small processing plants 100, with an annual processing capacity of 3050 tons of minor grains, an output value of17/400 yuan, a sales income of 167 1000 yuan and a profit of/kloc-. The development of minor grains processing industry has promoted the formation of local industrial bases, helped farmers realize the docking of agricultural products and markets, built a bridge between farmers and markets, and opened up a broad space for agricultural structural adjustment.

In 2003, Huan County continued to make a fuss about the development of small miscellaneous grains industry, with a planting area of 65.438+100,000 mu, 3 mu per capita, and an estimated total output of 65.438+300 million Jin, which can increase the per capita income of farmers by 230 yuan. Four towns, Quzi, Mubo, Hongde and Mao Jing, have established 222.5 mu of green production bases for small grains, all of which are planted with farmyard manure, and they are promoted throughout the county, striving to pass the green certification by the end of the year.
