Winter rice field mushrooms
After the rice is harvested, it is prepared for winter fields, used to cultivate mushrooms. The per mu output value can reach 4,000 yuan, deducting 800 yuan, and the net income per mu is over 3,000 yuan. Cultivation of mushrooms is also conducive to improving soil in paddy fields and fertility. 1, ingredients fermentation. Each straw uses 10,000 kilograms of straw, 8700 kilograms of dried cow dung, 165 kilograms of superphosphate, 270 kilograms of gypsum powder, and 82 kilograms of urea. It is piled in late September. First dry cow dung was sifted and sieved, pre-stacked for 1 day, and then there was a layer of straw-layer dung material. The stack was 1.5 meters wide, 8 meters long and 1.5 meters high. From the second floor, pour a layer of straw into the water once. After stacking it is covered with a plastic film. After five turnovers, the interval days were 7 days, 6 days, 5 days, 4 days, and 3 days. When the first turn is done, add all the urea evenly and spray the water properly. It is advisable to use 6-7 drops of water between the fingers when holding the material. In the second round of turning, add all the gypsum powder and superphosphate evenly, and pour a small amount of water in the dry place and the surrounding materials. The third and fourth rounds of turning usually do not add water. If there is a ring of blue-green material in the heap, it indicates poor ventilation. You can poke a hole in the heap with a wooden stick to improve the ventilation conditions. The last time it was turned, it required that there be 1-2 drops of water between fingers, and it was soft and tan. 2, choose to do the trick. Should choose to leeward sunny, easy dry drainage of rice fields. After the rice is harvested, the fields open deep trenches to dry the fields. Then, the width of 175 centimeters wide and 35 centimeters in width were used for ditching. The gutters were broken and laid on the surface so that the clams were turtle-shaped and dried. 3, sowing seeds. Before the material was placed under the ground, the surface was sprayed with bactericide and insecticide to control pests and diseases, and then a thin layer of soil was applied. In the middle of the surface, there are 17 cm of material left on each side, and the material is flattened after compacting. After 24 hours of inoculation, line spacing, hole spacing are 8 cm, 1320 bottles per acre with bacteria. After the inoculation, a plastic film and a straw curtain were placed 30 cm above the surface of the pimple (it was also possible to cover only 3 cm thick straw on the surface of the pimple). 4, management. Within 3-4 days after inoculation, the two films should be opened and ventilated every morning and evening for 1-2 hours. If the climate is dry, the material will dry white in a week and water spray will be required. 12 days after inoculation, the material surface was covered with soil. Continuous low temperature in winter, sunny days at noon to open the straw, increase the temperature within the film. When the temperature in spring suddenly rises, the film will be lifted during the day to dissipate heat and cover only the sun shade. During the fruiting period, 1.5 kg of potassium chloride and 150 kg of water are sprayed per acre to increase the quality of mushrooms. After receiving 2-3 tidal mushrooms, boiled and sterilized cow's urine was added to the urine with a pH value of 8 to increase the mushroom yield. China Agricultural Network Editor
