Speaking of growing potatoes, I am very familiar with it, because my hometown is in Weiyuan County, Dingxi City, Gansu Province. My hometown is the highest quality potato producing area in China - Dingxi City, Gansu Province, known as Known as the "Potato Capital" of China, our Weiyuan County is known as the "National High-Quality Potato Breed Base", the "National High-Quality Potato Virus-Free Base", and the "Hometown of China's Fine Potato Breeds".

Dingxi City, Gansu Province is located at the intersection of the Loess Plateau and the West Qinling Mountains. Therefore, it has a unique geographical environment and natural conditions, making Dingxi City, Gansu Province one of the best potato growing areas in China and even the world. Dingxi City in Gansu Province has become one of the three major potato producing areas in the country, the largest virus-free seed potato breeding base in the country, and an important commercial potato production base and potato product processing base in the country. It is known as the "Hometown of Potatoes in China". A large amount of potatoes are provided to various provinces and cities across the country every year.

Potato, also called potato, potato, is known as the fourth largest food in the world, and it is also the "life-saving potato" of our people in Dingxi. We also call it potato.

In the north, we start planting potatoes in March and April every spring. Now it is the cold weather of winter. It is impossible to plant potatoes. But how to grow potatoes well and obtain excellent pollution-free potatoes? We, the people of Dingxi, have done a great job.

Let’s talk to you about how to obtain pollution-free potatoes.

First: Have a good planting base

The soil environment for potato planting is: deep soil, loose soil, fertile soil, rich in humus, good drainage and good air permeability of sand or soil. In particular, choose slightly acidic sandy soil with loose soil, good drainage, and a pH value of 5.5-6.5 for planting. Potatoes will grow faster, mature early, produce more potatoes, have smooth skin, are easy to harvest due to disease, have high yields, and have good commercial properties. .

Of course, the soil also needs to be free from pollution from industrial wastewater and water sources, and it cannot use large amounts of chemical fertilizers and industrial fertilizers.

Second: Choose excellent potato varieties

Weiyuan County, Dingxi City, has a temperate continental climate. It is in the transition zone between arid and semi-arid climate zones and has a cool climate. Rainfall is a little sparse, but its soil and climate are very suitable for growing potatoes, and the potatoes are of high quality.

Especially in recent years, in our county, with the strong support of the municipal government, in order to cope with such a climate, the provincial party committee and government have specially set up a high-quality potato breeding station in our county, and have cultivated 6 high-quality potato varieties. varieties, formulated technical regulations for seed potato breeding, and gradually formed a three-level seed potato breeding system of "original species for virus-free tissue culture breeding - original species for net shed breeding - first-level species for high mountain isolation breeding".

After years of development, the county has currently built a germplasm resource bank of 124 varieties, screened and cultivated more than 30 varieties of Weishu and Longshu series, and promoted 22 demonstration plantings; a tissue culture greenhouse of 13,300 square meters has been built. m, there are 1,046 solar greenhouses, and field promotion has stabilized at 400,000 acres, with an annual production of 436 million virus-free seedlings, 480 million original seeds, and 800,000 tons of improved seeds.

So if you want to obtain high-quality pollution-free potatoes, you must first have potato seeds that adapt to the climate and growth environment, and you must also have high-quality potato seeds that are suitable for everyone.

Third: Scientific cultivation.

Planting potato is actually not difficult, and it is also very simple. The first step is to plant according to the local climate environment. Before sowing, the soil must be plowed to make the soil loose and breathable. When sowing, the row spacing is generally controlled at about 30-40 cm, the plant spacing is controlled at about 20-30 cm, and the distance from the ground is about 10-15 cm, and then the soil surface is covered flat so that there will be sufficient space for potato growth.

When planting potatoes, it is generally important to note that in areas with a humid climate and abundant rainfall, try to place the side with the bud mouth upward when sowing. This can increase the germination rate and maximize the germination rate. For possible germination, in areas with sparse precipitation and relatively dry soil, the bud mouth can also be facing downwards, in order to better contact the soil and absorb water, thereby increasing the germination rate and survival rate.

Fourth: Production Management

In the process of potato planting, scientific and reasonable management is very important. It is also one of the factors that ensures the high quality of potato and increases the yield. The first is the cultivation of potato. During germination, the soil should be loosened according to the situation to prevent soil compaction and affect the unearthed rate of the buds. After about a week after the buds are unearthed, when the buds are about 10 centimeters from the ground, fertilize and loosen the soil. Natural fertilizer is best to facilitate better growth and development of potato sprouts.

During the growth process, weeds in the field must be cleaned regularly to avoid affecting the growth of the potato plant and consuming unnecessary soil nutrients. When the potato grows to the point where it begins to bloom and spores appear. It is necessary to apply fertilizer and ridging. At this time, you also need to fertilize once. Farmyard manure is still the best quality, because after this fertilization, it is the time when the potato grows rapidly. Fertilization and ridging are important factors affecting the quality and yield of the potato. factor.

Fifth: Fertilization

Pollution-free potato means that there are no residues and effects of drugs. Generally, natural farmyard manure, organic fertilizer is the best, and corresponding and reasonable fertilizers are also required. Nitrogen, phosphorus and potassium fertilizer will grow high-quality potatoes.

Sixth: Prevention and Control of Pests and Diseases

During the growth process of potato, there will also be insect pests and other plant diseases. At this time, it is necessary to actively prevent and control them in daily management. Use pesticides rationally. It is strictly forbidden to use highly toxic and high-residue pesticides. We advocate the use of low-toxicity, low-residue, efficient and safe pesticides. Biological pesticides and mineral pesticides are preferred. At the same time, pay attention to the frequency, dosage and interval of pesticides to prevent organophosphorus. and pesticide residues such as carbamates.

Seventh: Safe Harvest

After more than half a year of careful cultivation and growth, the potato also needs a reasonable harvest time. If the harvest time is too early, the potato will not grow fully and the starch content will be insufficient. , too much moisture is not conducive to long-term storage and affects the quality. If the harvest time is too late and the temperature drops, it will cause low-temperature freezing damage to the potatoes and cause rot, which will also affect the quality.

At the same time, when harvesting, try to reduce damage to potatoes and reduce damage, which can increase the overall yield, increase overall quality, and increase income. During transportation and storage, try to avoid falling and bumping. , throw, these are all unfavorable factors that can affect the quality of potatoes.

Summary

Pollution-free potatoes have strict requirements for varieties, soil, and planting techniques. There is no room for carelessness. Therefore, care must be taken during the planting process. Plant so that you can harvest high-quality, pollution-free potatoes worthy of a year's hard work.
