Dryland Fertilization Technology
Fertilization method and soil management directly affect the soil moisture content and crop utilization of water and fertilizer. The use of fertilization in the drylands for spring fertilization for autumn fertilization, application of organic fertilizers, and scientific use of chemical fertilizers will generally increase soil water storage by 9%-10%, increase Millet yield by 40%, and increase maize yield. More than 20%. Re-application of phosphorus fertilizer nitrogen and phosphorus fertilizer formula based on different crops and target yield determine wheat nitrogen and phosphorus ratio is roughly 1:0.5-1, maize nitrogen and phosphorus ratio is roughly 1:0.45-0.8. The base fertilizer is dominated by organic fertilizer, phosphate fertilizer and potash fertilizer all as base fertilizer application. Nitrogen fertilizer is applied at 80%-90% as base fertilizer, and the rest is topdressed in time according to the soil moisture content. The application of high-quality organic manure fertilizer should be applied at 37,500 kg/ha or more, and there should be no (or less) composting of manure compost and straw washer fertilizer. Base fertilizer in the autumn combined with the last fall cultivation, the base fertilizer (including organic fertilizer and chemical fertilizer) is applied to the farmland. Appropriate depth of fertilization is preferably 20-25 cm.
