Secondly, we must master the standard of work: After soil preparation and fertilization, we should draw a 1.2-1.3-meter-wide line, dig 0.4-meter-wide and 0.3-meter-thick ditch in the middle, and place the excavated soil on both sides of the plant.
Thirdly, we should grasp the preparation and dosage of the temperature-raising agent fermentation bactericide: About 4 kg (4 bags) of temperature-raising agent strain of Jinbao greenhouse should be used per mu, and 40 kg of wheat bran or rice bran should be used. The better the fresh wheat bran is, the better. (usually 60 meters 7 meters of greenhouses, with 3 kg, wheat bran or rice bran 30 kg can be). Then, 1 kg of warming yeast is evenly mixed with 10 kg of rice bran or wheat bran, and the appropriate amount of water is about 8 kg. Mix evenly. (Add the water's humidity standard to match the hand tightly with the good material to see the water in the fingers but not Dripping water is suitable); can also be mixed with bacteria in 20-25 °C conditions, piled directly 12-24 hours. Prepare the corn stalks evenly and evenly in the gutters. After compaction, keep the sulcus at the same level as the ditch. After the stalks are put, spray the surface stalk with 2% urea solution (also use 2% brown sugar solution), and then Spread the prepared fermenting agent evenly on the stalk, beat it with a shovel, shake it properly, and let the part of the fungus fall down into the stalk layer. It is recommended that the best fertilizer be used in combination with 1-2-3 cubic meters per mus of decoction. Chicken manure is appropriate. Evenly mixing the remaining 30% of chemical fertilizer with fungicide can better increase and prolong the effect of fertilizer for more than one year. The effect will be better. Fertilizer can also be applied in different layers of straw, but the amount should not be too much.
Finally pay attention to soil cover, watering, planting and drilling. After the straw, fungicide and fertilizer are applied, cover the soil, cover 90% of the original open trench and cover it with straw, compact it with a shovel, and be careful not to expose the straw. The thickness of the cover soil is about 0.2 meters to form a sorghum. The remaining part of the soil can be made slightly higher in the channel to help with walking and watering. It is watered about 10 days before planting, and the straw is thoroughly drenched after 3 days. . At the time of colonization, digging or digging 8-10 cm away from the ditch, applying planting fertilizer (biofertilizer), insecticides, etc. into the planting pits, and irrigating planting water, and then planting seedlings. After planting, we must drill holes in the straw fermentation heap in time. Use a pointed wooden drill or steel drill with a diameter of about 3 cm to drill holes. The hole spacing is about 15 cm. The depth of the hole is suitable for obliquely penetrating the straw layer. Good ventilation and release of carbon dioxide.
The greenhouse straw warming fermenting agent and its supporting technology can be applied to various crop greenhouses (all kinds of greenhouse return season fruits, vegetables, various flowers and plants, etc.). After many years of actual experimental demonstration, the effect is very good.
Use of greenhouse warming agents
The use of greenhouse warming agents must first pay attention to site preparation and fertilization. 15-20 days before planting, remove the original backs of the field, deep plow tillage, and remove the manure, so that the quality of the farmyard manure (chicken, pig, horse, cow, sheep, rabbit and other manure) will be 3-4 cubic meters/mu. After mixing with 70% of compound fertilizer and chemical fertilizer dosage, spread it evenly on the surface of the wolfberry.
