In general, the utilization rate of nitrogen in dry land is not high, mainly due to the volatilization of ammonia, leaching of nitrate, and denitrification of nitrogen in the dry land. In order to increase the effect of applying nitrogenous fertilizers in drylands and reduce the loss of nitrogen from nitrogen, special attention should be paid to the following three points when applying nitrogenous fertilizers: Grab the key period The effects of applying nitrogenous fertilizer to crops during different growth periods are different. In general, nitrogen is not required for the seedlings at the seedling stage, but more nitrogen is needed during the heading and fruiting period. For example, before and after flowering, the topdressing nitrogen fertilizer can significantly increase the yield. Deep application Deep application of the combined cover soil, nitrogen fertilizer applied to the top soil 6 to 10 cm deep in the soil layer, can reduce the loss of nitrogen volatilization, improve nitrogen fertilizer utilization. The soil moisture content is suitable. Before the sowing, the ditch is opened and the fertilizer is applied on the underside or both sides of the seed to increase the fertilizer efficiency. In combination with organic fertilizers Organic fertilizer has a full range of nutrients that can improve the soil and improve soil fertility. Dryland applies organic fertilizer all the year round, can fertilize the soil and enhance the ability of the soil to retain water and fertility. For example, single-fertilizer N fertilizers in the drylands may yield higher yields in the short-term, but over time, the soil quality will deteriorate, and the effect of nitrogen fertilizer application will be greatly reduced. The combination of nitrogen fertilizer and organic fertilizer can achieve the purpose of high yield, stable production and high quality.
