I. Overview

Pleurotus ostreatus, also known as Pleurotus ostreatus, Pleurotus ostreatus and Pleurotus eryngii, commonly known as Pleurotus ostreatus, Pleurotus eryngii, Pleurotus Cicadae and Pleurotus eryngii, is one of the top ten mushrooms in the international mushroom trading market, and is also recommended for cultivation in developing countries by FAO. Because of its convenient materials, extensive management, good taste and high price, this variety is regarded as the main source of economic income by mushroom farmers. Cultivation of 1 mu of Pleurotus ostreatus can transform 5 tons of crop straw, which effectively cooperates with the government's straw burning policy during busy farming hours and has achieved great economic and social benefits.

Pleurotus ostreatus has strong stress resistance and wide temperature range, and can produce mushrooms at 4-3℃. Because of the long planting season, it is beneficial to adjust to be listed in other mushrooms or vegetables in the off-season. As a new product, Pleurotus ostreatus is easily accepted and recognized by consumers because of its unique advantages such as small investment, quick effect, great benefit, flexible cultivation place, no competition with agriculture, no competition with people for grain, no competition with land for fertilizer, high yield, low production cost and rich nutrition.

Pleurotus ostreatus is a natural and pollution-free green wild plant, which is not affected by feed additives, pesticides and hormones, and is favored by consumers with high protein and low fat. At present, the market is mainly restaurants, hotels, frozen food factories and so on, and the market prospect is extremely broad. Timely development will have a fat profit return.

The planting process of Pleurotus ostreatus:

Collecting wheat straw/rice husk-humidifying-spreading-inoculating

1, evenly spreading fresh mildew-free' wheat straw/rice straw' on the surface of woodland with a thickness of 15-2CM

2, and using water spraying facilities. The raw materials should be shaped into turtle's back, and the size of the strains should be the best, and the strains should be evenly spread on the surface according to the font, based on the principle that the strains are like dew but not dew. Covering soil: It is best to take humus soil below 1 cm on the surface and fertile soil in vegetable garden, cover the surface of the material with 1-2CM, preferably no more than 2 cm, and cover the surface of the soil with 2 cm of wheat straw/rice straw for planting.

4, precautions; It is required that the width of wheat straw/straw paved is 5-6cm and the height is controlled at 25-3cm. When planting is completed, the width of the border is not more than 8cm, and the middle aisle is 3-4cm. The planting and utilization area of Pleurotus ostreatus per mu is 4-45 square meters.

Second, economic benefit analysis

Estimation of total production cost

1. Raw material cost: 12 strains/mu, planting labor 15-3 yuan/mu, 1 ton rice husk cost 4-6 yuan, and 3 tons wheat straw or rice straw cost 1-12 yuan per mu.

2. The average yield of Pleurotus ostreatus is 2-35 kg per mu, and the selling price is 4.5-8 yuan per kg. According to 4.5 yuan per kg, the selling income of Pleurotus ostreatus per mu is 1125 yuan, and the net profit can be 795 yuan if the cost is removed from 33 yuan. For example, the selling price of fresh mushrooms is calculated by 8 yuan per kg.

3. The products sell well, and restaurants, hotels and canned food factories will come to ask for goods.

Project background

Pleurotus ostreatus is mainly planted under the forest. In the abandoned field, all kinds of fruit trees and poplar forests can meet its growth needs, and there is no need to build a greenhouse, a mixing site or a yard, and no need to purchase other planting facilities. Pleurotus ostreatus is planted by using the space under the tree and shading from the shade, and it can be said that it can be planted without affecting the growth of trees. The whole planting process does not need fertilization, pesticide spraying, etc., and does not occupy labor. It is a good project for laid-off workers to develop re-employment and farmers' friends to engage in the tertiary industry.

In recent years, the industrial structure adjustment of the under-forest economy has been paid unprecedented attention by the whole country. Through the development of modern agriculture, farmers can increase their income and get rich, eliminate low income, and provide an excellent opportunity to fundamentally solve the problem of increasing their income and getting rich and realize sustainable economic development. The government adheres to the guidance of Scientific Outlook on Development, combines the development of the situation and the expectations of the masses, organizes forces, and actively explores new ways for farmers to increase their income and become rich. Take vigorously developing planting as a breakthrough to get rich. Establish leading enterprises in planting industry, develop "ecological, safe, high-quality, intensive and efficient" modern agriculture, and build a green ecological county. Protect and rationally utilize water and soil resources, improve the ecological environment, and promote sustainable economic and social development. In order to build a harmonious new countryside, according to the requirements of the central authorities, it is necessary to persist in taking economic construction as the center and increasing farmers' income as the starting point and foothold, liberate and develop rural productive forces, change the mode of economic growth, develop rural economy, and actively develop modern agriculture with resource conservation, technology-intensive, diverse functions and safe quality. This is the background of this project.

This project has the advantages of less investment, short construction period, quick effect, great benefit, no competition with agriculture, no competition with people for grain, no competition with land for fertilizer, comprehensive development and utilization of waste materials, flexible cultivation sites, and good social, economic and ecological benefits. Broad market prospects, guaranteed raw materials and strong anti-risk ability. The development of this project is of positive significance for developing under-forest economy, improving soil and ecological industry, so this project is feasible.
