Interplanting and cultivation of Cucumber and Coprinus comatus

Coprinus comatus, also known as Pleurotus ostreatus, is a typical medium-temperature breed, which can not produce mushrooms normally when the ground temperature is lower than 8 degrees Celsius. When the ground temperature is higher than 30 degrees Celsius, the mycelium vitality decreases, a large number of parasitic bacteria appear, and Coprinus comatus is close to the end of harvest. Coprinus comatus can be produced annually by cooling in summer and increasing temperature in winter, but the cost of cooling in summer is high and the benefit is low. Interplanting Coprinus comatus in vegetable greenhouse in winter not only saves the heating cost, but also does not encroach on the effective space of vegetables. it can also provide part of carbon dioxide gas fertilizer for vegetables, which is a cultivation model worth popularizing. 1. Raw material formula (1) wheat straw 60%, dried cow dung 25%, wheat bran 12%, corn flour 3%. (2) 30% of rice straw, 20% of corn straw, 15% of wheat bran and 5% of corn flour. (3) 40% corncob, 45% bean straw, 12% wheat bran and 3% corn flour. (4) 40% of Pleurotus ostreatus waste, 45% of bean straw, 13% of wheat bran and 2% of corn flour. Among the above four formulations, each 50kg culture medium was supplemented with special fertilizer 0.5kg for Coprinus comatus, 2.5 kg of quicklime, 25% carbendazim 0.1kg, magnesium sulfate 0.02kg, zinc sulfate 0.005kg, water 60-80kg. 2. In the raw material treatment, corncob, soybean straw and rice straw are fully dried and crushed, so that corncob particles are similar to corn kernels and wheat straw, rice straw and bean straw are similar to bran crumbs, so that they have good ventilation, strong water retention and are suitable for mycelial growth. 3. The mixing method adopts the method of "stacking oxygen fermentation". (1) spread the dry material on the insecticidal site, add it to the dry material according to the amount of special fertilizer, water and quicklime needed in the formula, mix it well, pile it into an earthwork sample, cover it with multiple pores, hit the surface of the material pile with insecticides, cover it with plastic, and support oxygen around the membrane. Wait for the material temperature to rise to 62 degrees Celsius and keep turning for 48 hours. (2) while turning the pile, add the auxiliary materials, mix well, then stack, pierce the hole and apply medicine, cover the film, wait for the material temperature to rise to 62 degrees Celsius again, keep turning the pile for 36 hours. (3) spray carbendazim while turning the pile, adjust the moisture content to 65%; adjust the pH value to 8 with quicklime, mix well, and wait for the material temperature to drop below 25 degrees Celsius. 4. Bagging bacteria using "both ends of porous oxygen bagging" technology, selected diameter 26cm, long 45cm low-pressure ethylene plastic bag, filled with 3 layers of material, sowed 4 layers of seeds, the amount of seed used was about 18%, the two ends of the bag were covered with sticks with a diameter of 10-12mm, each with a depth of 4-5 air holes for the length of the bag, the mycelium was covered with soil for 15-20 days. 5. The cultivation of Coprinus comatus mainly uses the isolation belt of 70cm at the front of the cucumber shed to dig deep 40cm and wide 65cm ditch along the length of the shed, cover 10cm thick fermented rice straw and wheat straw, remove the bacterial bag film, put 3 rows in the border, fill the gap with soil, and cover the bag with 3-3.5cm thick. After covering the soil, beat beta-cypermethrin and trimethoprim for 2-3 days and water again. After 15-20 days, a large number of Coprinus comatus primordia appeared. When the fruiting body cap is separated from the stalk, it is harvested to ensure the commercial quality. after picking a tide of mushrooms, the mushrooms are watered with nutritious water (100kg water plus potassium dihydrogen phosphate 0.2kg) and sprayed with cypermethrin for 4-6 tides. 6. The main advantages are as follows: (1) the isolation belt formed by the buried 60cm wide Coprinus comatus bag can effectively isolate the low ground temperature outside the shed from being transmitted to the shed, and the Coprinus comatus culture material can generate heat, which can increase the temperature and air temperature in the interior of the shed by 1 to 2 degrees Celsius. In addition, carbon dioxide released by Coprinus comatus provides gas fertilizer for cucumber growth, while oxygen released by cucumber provides conditions for Coprinus comatus growth, both of which are mutually beneficial. (2) the low yield of interplanting Pleurotus ostreatus with cucumber is due to the release of a large number of spores from Pleurotus ostreatus, which seriously affects the growth of cucumber, while Coprinus comatus does not release spores and will not affect the growth of cucumber.
