Ten Ways to Improve Crop Drought Resistance
2018-04-27 14:00:29
Build forest network: farmland within the forest network, soil evaporation and crop transpiration reduced by 25%, air relative humidity increased by 18% to 20%, soil moisture increased by 5% to 12%.
Cultivating and impounding water: Soil moisture content increased by 12% through deep plowing, storage, conservation, repression, and cultivating.
No-tillage cultivars: no-tillage sowing can inhibit soil moisture evaporation, and after ploughing and sowing, water loss is more than 60%.
Gravel protection: Spread a layer of 5-8 centimeters of gravel on the farmland, and then sowing, soil moisture can be increased by about 1% to 5%.
Rational fertilization: Apply more than 60 cubic meters of high-quality organic fertilizer per hectare, 30 kg of phosphate fertilizer, 20 kg of potassium fertilizer, and appropriate amount of boron fertilizer, which can significantly improve the drought tolerance of the crop.
The grass is planted in the field: About 6,000 kg of grass are planted per hectare of farmland, which suppresses the evaporation of soil moisture, and the field moisture content can increase by 2% to 9%.
Film Coverage: The cover film can effectively prevent water evaporation, and the soil moisture content generally increases by 3% to 6%.
Cover shade net: cover shade net, the net temperature can be reduced by 6 ~ 9 °C, the relative air temperature increased by 15%.
Seed soaking: Soaking cotton, kenaf and other crops with-6 copper sulfate can significantly improve its drought resistance.
Soaking with biogas slurry: Biogas slurry contains not only nitrogen, phosphorus, potassium, copper, iron, zinc, and other nutrients, but also ammonium, organic acids, and other resistant substances. Soaking with biogas slurry will significantly improve disease resistance, drought, and seedling growth. General increase of 5% to 10%. The soaking method is as follows: the seeds are broiled and put into a well-breathed woven bag, and one end of the rope is tied to the bag mouth, and is put into the biogas slurry of the digester, and the other end is fixed at the edge of the pool. Wheat, corn and cotton seeds are generally soaked for about 12 hours. Sweet potatoes and potatoes are usually soaked for 4 to 6 hours. Melons and beans are soaked for 2 to 4 hours. After soaking, the seeds are sowed.
