Straw mushroom meat is tender and tender, tastes delicious, has a high nutritional value, so the sales in the market is relatively good, today I will share with you the use of straw can grow straw mushrooms? Straw seed grass technology?
Selection of raw materials for straw mushroom cultivation:
The main raw materials for the production of straw mushroom are straw such as wheat straw and corn, which can solve the problem of straw treatment, low cost, wide source of raw materials, easy to master technology and quick effect. After the cultivation of straw mushroom, the remaining waste material is directly used as fertilizer to turn over the soil, which can increase the organic matter content in the soil, improve soil permeability, reduce soil pathogenic bacteria and toxic and harmful substances, and is conducive to the normal production of the squat vegetable.
Preparation of straw mushroom planting shed:
When the straw mushroom is cultivated in summer, the shed has been in a high temperature and high humidity environment, and the materials for constructing the shed, such as bamboo rafts, steel frames, and grass rafts, are greatly damaged. Therefore, straw mushrooms are rarely cultivated in new greenhouses, but they are most suitable for cultivation in old sheds with long planting time. They are not afraid of damage to the sheds and other facilities, and can improve the soil and increase the benefits.
Summer straw mushroom planting steps:
Step 1: Processing of straw mushroom raw materials:
Fresh wheat straw, corn, cottonseed hulls, etc. are selected as raw materials. Here, for example, wheat straw is firstly immersed in 3%-5% lime water for 24 hours, then drained and drained, and mixed with gypsum, livestock manure, phosphate fertilizer, grass ash and other building fermentation. When the straw is fermented, the pile width is generally 1.2 meters, the pile height is 1 meter, and the length is more than 1 meter. The vent hole should be properly worn in the pile. After the pile is finished, cover the film to moisturize. The prepared culture material should be soft in texture, 70% water content, and the pH value is adjusted to about 9.
Step 2: Straw mushroom planting method and sowing:
Ridge-type sowing is a new method for high yield of straw mushroom, and the sowing is carried out by three-layer ridge cultivation. First spread the culture material on the ground, 30-40 cm wide and 10 cm thick, and spread a layer of bacteria along the surrounding. The wheat bran is wetted with 3% lime water and placed in the mushroom house for secondary fermentation. Sprinkle a layer of 10 cm wide wheat bran in the planting center, and lay a second layer of culture material, sowing, and smashing wheat bran. The top layer is covered with a layer of culture material, and a layer of bacteria is planted on the surface and covered.
Step 3: Management of straw mushroom:
After sowing the straw mushroom, keep the temperature of the culture material at about 36 °C, and keep the film for 2-4 days. Then cover a thin layer (about 1 cm) of fertile sandy loam on the bed surface, and spray 1% lime water on the soil layer to keep the soil layer moist, and then cover the plastic film. After the soil is covered, the room temperature is controlled at about 30 ° C, and the temperature of the material is maintained at 35 ° C. Properly ventilate while maintaining the material temperature.
On the 4th to 5th day, the mushroom water should be sprayed once. After spraying, the air should be properly ventilated to avoid closing the vents immediately after spraying, otherwise the hyphae will be long. Under normal conditions, young mushrooms begin to form 6-7 days after sowing. At this time, it should be kept warm and moisturized, and properly ventilated.
The temperature of the culture material is maintained at 33-35 ° C in the shed, and the relative humidity of the air is about 90%, and a certain amount of scattered light is maintained. Do not spray the mushrooms directly with water. When the humidity is not high enough, spray with water at about 30 °C. Mushrooms are usually harvested about 10 days after sowing.
