First, benefit analysis

The straw mushroom production time is short, from inoculation to harvest only 10 to 12 days, the entire production cycle is only 1 month, 4 to 6 batches can be planted in 1 year. According to the calculation of 2,500 kg in 100 m2, 750 kg of straw can be produced (30% conversion rate). At a price of 5 yuan per kilogram, the output value of each batch of 100 square meters (monthly) amounts to 3,750 yuan. The cost of investment is only 1300 yuan, including 300 yuan for seed production, straw (wheatgrass) and rice bran (money) for a total of 1,000 yuan. Net income reached 2450 yuan. If 4 to 6 batches are profitable, 10,000 to 15,000 yuan.

Second, the cultivation techniques

1. Preparation of original species and culture medium of bacteria species: 80% of chopped straw, 19% of wheat bran (rice bran) and 1% of calcium carbonate. Cottonseed husk medium formulation: 90% cottonseed hull, 8% wheat bran, 1% gypsum powder and 1% superphosphate. The original species can be 750 milliliters of the original species bottle or 14 centimeters and 28 centimeters of polypropylene bags. The cultivar can be used 15 cm 30 cm polyethylene bags, one inoculation (plus ring tampon). Hyphae can be overgrown for use in 15 to 20 days. Good straw mushroom strains, white or yellowish hyphae, no or little red-brown chlamydospores, no bacteria, no pests.

2, cultivation

Long straw package semi-clinker cultivation. 1 raw materials: straw, rice bran or wheat bran, corn flour, peanut dry cake or rapeseed dried cake powder, gypsum powder, compound fertilizer or sulfuric acid, potassium dihydrogen phosphate, lime powder. 2 Formula: dry straw 50 kg, rice bran 12.5 kg, corn powder 1 kg, gypsum powder 1 kg, potassium dihydrogen phosphate 200 g. Or 50 kg of dried straw, 5 kg of rice bran, 2 kg of corn flour, 2.5 kg of wheat bran, 0.5 kg of gypsum powder and 200 g of potassium dihydrogen phosphate. 3 dipping grass, ingredients, packaging, sterilization, inoculation. The whole row of grass will be immersed in the pool, and pressed with stones, then add 3% to 5% of lime water, soak for 12 to 24 hours, picked up and then properly dry, while mixing rice bran and other accessories. The rice straw is packaged with a mold, a layer of grass is sprinkled with a layer of rice bran accessories, a total of four layers of grass four layers, each package of dry weight 5 ~ 7.5 kg, packaged with a steam sterilization device for sterilization 4 ~ 6 hours, cooling to 40 Below °C, inoculum culture. 4Cultivation sites can be selected as indoor or outdoor greenhouses and arbors, with a “well” shaped three-dimensional germ, and after 7 days, they can enter the mushroom management. During this period, the air humidity should be maintained at 80% to 90%, and the temperature should be controlled at 28 to 32°C. .

Sunshine condition: apple is the fruit tree, the central health area of the whole year is nearly 3,800 hours, is beneficial to the Apple Fruit coloring. The piedmont apples are red and bright.
Temperature difference factors: ambassador apple nighttime respiration weak temperature gap between day and night, consume less organic matter, the accumulation of organic matter during the day more, that apple store down a large number of glucose sugar candy, etc have better taste. The average diurnal temperature difference between apple and apple is 14 degrees centigrade, and the larger diurnal temperature difference ensures the sweet and delicious characteristics of the apple.
Other factors: frost can make apple blossom and fruit, which can cause frozen flower jelly, which is bad for apple's production. The piedmont apple has been kept at least 167 days without frost for the whole year, which minimizes the influence of apple on yield and quality.
