Key points of High-yield cultivation techniques of Mushroom in Paddy Field
1 grasp the best sowing time according to the adaptive temperature of mushroom growth, and determine the stacking time and sowing time according to the altitude. Taking the climatic conditions of our Dazhou area as an example, it is appropriate to pile up materials at an altitude below 500m on September 20 and left grid on October 13, and at an altitude of 800m to 1000m, it is appropriate to pile materials on September 10th and sow seeds on September 23rd. If sowing in advance will lead to the first batch of mushrooms unearthed in high temperature and die; sowing too late, it will affect the yield of mushrooms.
(2) to adjust the formula of cultivation materials reasonably, with the decrease of farming cattle in rural areas, the area of mushrooms cultivated with cow dung is also limited accordingly. Therefore, rice, wheat and grass are added with 8%-10% rice bran and 2%-3% compound fertilizer containing nitrogen, phosphorus and potassium to supplement carbon and nitrogen nutrients needed for mushroom growth and development.
(3) excellent mushroom strains are selected. at present, 2796 varieties of mushrooms are used in our region. Strain is the dominant factor in the whole cultivation process, which is very important. No matter it is introduced or kept by oneself, the strain that is authentic, robust, suitable for age and free of miscellaneous bacteria infection must be selected before it can be used in production.
4 selection of soil quality of mushroom paddy field the soil quality suitable for planting mushroom is "three or seven sticky" loam field. Due to the over-sticky soil, the proportion of capillary pores is small and the air permeability is poor; while the sandy soil shows water consolidation and poor air permeability, while the sandy soil shows water consolidation and poor air permeability, these two kinds of soil are not conducive to the high yield of mushrooms. At the same time, attention should be paid to the selection of fields close to water sources and conducive to drainage.
(5) the design of mushroom shed and border bed should be 5m wide and 15m long. If the mushroom shed is too long and the space is too large, it is not conducive to temperature control and ventilation, which will cause serious carbon dioxide deposition. The width of the border bed is 60cm and the width of the furrow is 50cm, which is beneficial to air permeability and improve the yield and quality of mushrooms.
(6) the prevention of diseases and insect pests in mushroom bed occurs from time to time in the process of mushroom cultivation. In order to reduce the mushroom loss caused by diseases and insect pests, the policy of "prevention first and combination of prevention and control" should be adopted. First of all, to ensure that the raw materials for cultivation are fresh, dry and mildew-free, strictly carry out stacking fermentation, and spray insecticidal and low-toxic pesticides at the last turn (heap). In addition, the soil particles covered with soil should also be strictly disinfected to avoid bringing diseases and insect pests from the soil particles.

Cultivation techniques of Agaricus bisporus in Paddy Field
The cultivation of Agaricus bisporus in paddy field is a "rice-mushroom-rice" farming mode in which culture materials are directly spread on the paddy field after rice harvest and mushroom is cultivated by covering soil. After rice harvest, the straw was dried in the sun, fermented and cultivated in situ, and covered with straw curtain, small plastic arch shed or plastic greenhouse, which saved the process of building mushroom house and transportation of raw materials, and greatly reduced the production cost. In addition, the rotation of cultivated land every year can effectively control diseases and insect pests and make mushroom products meet the requirements of pollution-free quality. In addition

How to get High yield of Mushroom at present
First, cure diseases and kill insects. For mushroom houses where no disease has been found, 15% lime water (slurry) is first painted on the surrounding walls, and the bed surface can be combined with water transfer to spray 1% lime clarification solution or 0.5-1% ammonia solution; for mushroom houses that have been infected with miscellaneous bacteria, spray 500 times carbendazim or Bordeaux solution 1-2 times before inoculation. Clean the inside and outside of the mushroom room before feeding, and spray 1% dichlorvos or dimethoate once again; after feeding, spray 0.5% dichlorvos 1-2 times, or dip 2% dichlorvos with cotton balls, and hang it in the mushroom room
