Efficient cultivation method of middle shed mushroom

Intensive greenhouse cultivation is the main mode of mushroom cultivation in China, but it requires a certain amount of land, and the capital investment is large. Compared with the greenhouse planting mode, the biological efficiency of the greenhouse planting in the greenhouse can be doubled, the production cost can be saved by 30%, and the net net profit can reach over 5,000 yuan.

First, preparation before planting 1. Cultivation season arrangement. In the middle and late August, crops were planted in the ground and planted in mid-September. In October, the mushrooms were grown and the cultivation was completed in May of the following year. If the temperature is suitable, it can be sown in advance to late August and the fruiting can be achieved in advance. 2. Cultivation site selection. Choose a land with sufficient water supply, groundwater level is not too high, and the thickness of soil layer is not less than 40 cm. 3. Shed structure. The layout of the mushroom shed is in a north-south direction. The middle shed can be built to a variety of specifications according to local conditions: a 4-meter-wide shed, a bamboo scaffold with a height of 4.2-4.3 meters is used to form a 3-meter-high horizontal scaffolding, and bamboo spacing is 70-100 cm. The size of the bamboo pieces is determined, and the scaffolding is horizontally connected and fixed with three bamboo pieces. The two sides of the scaffold are fixed with two bamboo stakes; the six-meter wide shed is formed with two 3.5-meter pieces of bamboo to form a 6.3-meter bamboo piece. Pieces, made of 6 meters wide into scaffolding, the middle with two rows of bamboo stakes support; sheds, with two 2 meters long bamboo piles take adult font, and on both sides with bamboo pieces connected. After the scaffolding is erected, the black plastic film is overlaid on the film, and a straw curtain with a corresponding length is covered on the film. The membrane at both ends of the shed can be opened and closed, and the film and the ground at both sides are pressed and buried. The length of each shed is 15 meters. The distance between the shed and the shed is 50-70 centimeters, and the middle is digging the drainage ditch, which is 30 cm wide and 40 cm deep. 1 mu of land can take 4 meters wide 14 or 6 meters wide 10, effective cultivation area of ​​3200 square feet, the availability rate of 55%.

Second, mushroom culture material fermentation Each acre shed cultivation of mushroom material suitable formula: straw 4250 kg, cabbage cake 150 kg, urea 30 kg, ammonium bicarbonate 15 kg, compound fertilizer 150 kg, gypsum powder 100 kg, lime 100 kg, Carbon to nitrogen ratio 30:1; straw 4000 kg, dry pig manure 1500 kg, cabbage cake 100 kg, urea 30 kg, superphosphate 50 kg, gypsum powder 100 kg, lime 100 kg. The simple secondary fermentation method for cultivating material: First, the raw materials were pre-wet at the beginning of August, and were fermented before the construction of the reactor. The reactor was turned 3 times in 5 days, 4 days and 3 days, and then transferred to the post-fermentation period. A simple bedstead with a height of 30 cm above the ground was erected with bamboo sticks. The bed width was 1.1 meters and the length was dependent on the amount of material. The material was transferred to the bed and piled in the material, the diameter of bamboo sticks 10-15 cm, rod spacing 10-15 cm, cross-arrangement between the holes, the material pile to 1.2 meters high, the material piled up after the bamboo rod out. Take a simple arch-shaped bracket outside the material pile, the top material 30-35 centimeters, surrounded by 15 centimeters away from the stockpile, with a white film to close the arch bracket, leaving a vent at the bottom of the floor, the film on top of the arch cross-linked with each other, you can start close. Using solar energy and bioenergy agglomeration, the stockpile temperature was raised to 65°C and maintained for 5-6 hours; then it was reduced to 50°C-55°C, and it was finished after about 5 days. The fermentation material has a pH of 7.5 and a moisture content of 58%-60%.

Under normal circumstances, disposable Masks are replaced once every 8 hours, and cannot be reused. Disposable masks are made of more than three layers of 28 g non-woven fabric; the bridge of the nose is made of environmentally-friendly all-plastic strips, without any metal, with breathable, comfortable, especially suitable for electronics factories, daily use. The disposable medical surgical mask can prevent respiratory tract infection to a certain extent. It is made of two layers of non-woven fabric and filter paper. It consists of two layers of fiber non-woven fabric, which is professionally used for medical treatment. More than 99% of the filter bacteria can be filtered by ultrasonic welding.
