In high temperature and dry season, under the irradiation of strong light, the temperature of bare ground can reach 50°C, the evaporation is intense, and the concentration of surface water solution increases sharply. At this time, if the same amount of fertilizer is applied under normal weather, the crop yield can not be maintained or not. Increase production, and it is likely to reduce production. For example, when rainfall is moderate, maize yields 12 kg of pure nitrogen per acre, which may yield high yields. If the same amount of fertiliser is applied at high temperatures and drought, it will face the risk of reduced production. Some farmers reported that the high-temperature and drought last year, Atractylodes fertilization level was the same as the previous year, and as a result, the yield of Atractylodes macrocephala did not increase, but no fertilization had a higher yield than fertilization. Fertilization in the morning, although the operator feels more comfortable, but with the rise of the sun, the temperature rises sharply, the water is quickly evaporated, the crop absorption time is short, the fertilizer utilization rate is low; noon fertilization, due to high temperature, is not conducive to fertilizer Absorption and personnel operations; late fertilization, both suitable for personnel operation, but also make up for short crop absorption shortcomings (because the night is a process of lowering temperature, evaporation of surface water is weakened, water retention time is long), is the best fertilization time.

High-temperature and dry fertilization must be more phosphorus and less nitrogen
Applying phosphate fertilizer on the one hand, on the other hand, phosphate fertilizer can be more effectively used to produce a good fertilizer effect; on the other hand, phosphate fertilizer can increase the utilization of water in the soil and play a mutually reinforcing role. In addition, sufficient phosphorus can increase the utilization of nitrogen and play a role in raising nitrogen by phosphorus. Reduce the application of nitrogen fertilizers, especially carbon-ammonia and high-concentration nitrogen fertilizers that are susceptible to thermal decomposition, so as not to cause crops to sprout.
