Editor's note: Temperature is a very important condition affecting the effect of fertilizers. It affects the conversion of fertilizers in the soil and the accumulation of available nutrients on the one hand; it affects the growth of crops and the respiration of roots, and thus affects the absorption, transportation, and utilization of nutrients by crops. The speed. In summer, the climate is characterized by high temperature and drought. How to increase fertilizer efficiency and reduce fertilizer damage is the focus of fertilization in this period. This version of the manuscript for summer fertilization methods and precautions to sort out, in order to provide reference and help for farmers.

Fertilizer varieties: Apply less fertilizer and less nitrogen fertilizer

Phosphate fertilizers, on the one hand, can be used more effectively at higher temperatures, resulting in good fertilizer efficiency; on the other hand, they can increase the availability of water in the soil and act to relieve drought and promote each other. In addition, sufficient phosphorus fertilizer can increase the utilization of nitrogen, play a role in phosphorus nitrogen. Reduce the amount of nitrogen fertilizers, especially carbon-ammonia that is easily decomposed by heat, because heat-decomposable carbon ammonia and high-concentration nitrogen fertilizers can easily cause crops to sprout.

Fertilizer amount: can not be the same amount of fertilizer as normal weather

In high temperature and dry season, the soil moisture evaporates strongly and the concentration of surface water solution increases sharply. At this time, if the fertilizer is applied as much as under normal weather, the crop yield will not be maintained or increased, and production may be reduced. 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.

Fertilization time: early morning and afternoon discomfort best

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 can make up for the shortcomings of short crop absorption time (because night is a process of decreasing temperature, evaporation of surface water is weakened, water retention time is long), is the best fertilization time
