After the temperature-increasing fermentation aid is added to the straw material, the functional microorganisms multiply and multiply rapidly, and the microorganisms can generate a large amount of heat, carbon dioxide, enzymes, and other various metabolites in the process of fermentation decomposition. The supply of carbon dioxide is sufficient, and the temperature and ground temperature are greatly increased, which contributes to the smooth growth and development of crops under adverse environmental conditions such as low temperatures; the proliferation of beneficial microorganisms, various enzymes and other disease resistance factors formed in the course of biochemical reactions make crops resistant to diseases. The capacity is greatly enhanced, which can save more than 70% of the cost of pesticides; straws produce a large number of organic and inorganic nutrients after maturity, so that the soil is rich in nutrients and fertility, so that the crop grows robustly and can save more than half of the amount of fertilizer; due to chemical fertilizers and pesticides The quantity is greatly reduced, which can significantly improve the quality of fruits and vegetables. The appearance and taste are significantly improved. The selling price is good, the commodity rate is high, and the economic benefits are significant.
Second, the actual effect:The effect of temperature increasing fermentation aids in greenhouses has good comprehensive economic benefits and ecological benefits.
1, warming and heat preservation effect is obvious: generally can increase the underground 20 centimeters of ground temperature 4-6 °C, the average temperature increase 2-3 °C, early spring crops can be planted in advance 10-15 days, planting, can be 7-10 days ahead, flowering, results, Can extend the harvest period of more than 30 days.
2. The concentration of carbon dioxide increases exponentially: it can increase the carbon dioxide concentration in a certain area of ​​greenhouse space by 4-6 times, increase the water use efficiency by 80%-150%, and increase the photosynthetic efficiency by more than 50%.
3. The disease prevention and disease resistance effect is good: Practice has proved that the use of greenhouse warming agents can reduce the dosage of pesticides by more than 70%, and some can even do basic use of pesticides instead of chemical pesticides. The environmental protection effect is extremely significant.
4. Good effect of improving soil fertility: It can increase soil organic matter and humus, enrich the population structure of soil beneficial microorganisms, and can greatly improve the physical and chemical properties of soil, such as soil pellet structure, aeration, water retention and fertility, etc., can all be significantly improved. With the increase, the number of roots and the fresh root weight increased accordingly.
5. Significant economic benefits: Increase input-output ratio. Using greenhouse warmers, the average yield per mu can be increased by more than 30-50%, and the input-output ratio can reach 1:20 or higher, and waste utilization and benign circulation mechanisms can be formed.
Third, the operation method:
1. Soil preparation and fertilization: remove field stubbles 15-20 days before planting, and deep-rotate flat stubble; fine-quality decomposed farmyard fertilizers (such as chickens, cattle, horses, sheep and other livestock excrement) 3-4 square centimeters per mu , After mixing with 70% of compound fertilizer and chemical fertilizer dosage, spread spatula evenly.
2. Standards for width and trenching: After fertilization for soil preparation, the width of 1.2-1.3 meters in width shall be crossed, and 40 centimeters wide in the middle and 30 centimeters in depth shall be used. The soil to be excavated shall be placed on both sides. .
3. The preparation and dosage of Goldbeet bacteria (fermenting agent): About 4 kg (4 bags) of Jinbao starter, 40 kg of wheat bran or rice sugar (about 3 kg for a 60m×7m shed). 30 kg of wheat bran or rice sugar, the newer the better.) Mix 1 kg of bacteria with 10 kg of rice sugar and mix evenly. Add about 8 kg of water to mix evenly. You can also mix the good bacteria at 20-25°C for 12-24 hours. (Add water and humidity standard. With hand-poured with good material, fingers see the water droplets do not drip is appropriate).
4, put the straw and fermentative agent: the prepared corn stalk flat put the ditch, after compaction is consistent with the ditch along the edge; straw put, first with 2% urea aqueous solution, spray wet surface straw, Then, the prepared fermentation bacterium was evenly spread on the straw and beaten with iron milling, and the vibration was properly applied to make the part of the fungus fall in the straw layer. It is recommended to use fertilizer to put in 1-2 parts per mu of chicken droppings (or Other livestock manures are evenly mixed with the remaining 30% of fertilizer compound fertilizer. Fertilizer application above can increase fertility and extend fertilizer effect for more than 1 year. The effect is better. This fertilizer can also be used to stratify the middle of straw, but Do not use too much. .
5. Cover soil and irrigation: After the straw, fungicide and fertilizer are applied, cover the soil. Cover the soil with 90% of the excavated earth and put it on the straw. Make sure that the straw is not damaged and the thickness of the soil is about 20 cm. , forming a high sorghum. The remaining 10% of the soil can be made on the channel to a slightly higher point to facilitate the aisle and watering. After the soil is planted, about 10 or so watering, the straw drenched. Watering 2-3 Day afterwards tidy up again. Prepare for colonization. .
6. Colonization and drilling: When planting, open the ditch or dig a hole to plant the seedlings at the distance of 5-10 cm from the ditch. Before the planting, plant the fertilizer (biofertilizer), fungicides, insecticides, and plant the ditch, and drench it. Planting water. Immediately after planting, drill a hole in the return pile. Use 3 cm thick tipped wood brazing or steel brazing to drill holes. The depth of the hole is about 15 cm to penetrate the straw layer diagonally. The purpose is to For good ventilation and release of carbon dioxide. .
Fourth, pay attention to matters
1. Timely replenishment: Fermentation reactors are well-produced and should be filled with water in a timely manner after 10 days, but should not be too diligent, excessive, and the humidity should be maintained at 50-60%. .
2, can be controlled according to the growth period requirements of the exhaust. .
V. Applicable to a wide range of applications: Goldbeet greenhouse straw fermentation heating technology can be used for other kinds of crops, with the same effect.
Three, greenhouse heating agent above ground instructions1. Select four to eight square yards per mu, preferably four points spread out.
2. About 4 kg (4 bags) of Jinbao starter is used per mu, and 40 kg of wheat bran or rice bran are used per mu (usually about 3 kg for 60m×7m shed, 30kg for wheat bran or rice bran).
Dilution strains: 1 kg of bacteria, 10 kg of wheat bran or rice bran, 8 kg of water mixed evenly, with the use of mixing.
3, preparation of materials: rice straw (preferably about the length of 30 cm), feces.
4. Material stacking: Rice straw and manure were added at a volume ratio of 7:3.
5, material strains mixed: The material moisture is adjusted to 50--60%, after adding bacteria, the material and bacteria mixed.
(50--60% water determination method: hand with a good material, fingers see water droplets is not appropriate)
