Hot and dry fertilization needs attention
Fertilizer varieties Apply more phosphorus fertilizer less nitrogen fertilizer. The application of phosphate fertilizers in high temperature and dry weather is due to the fact that phosphate fertilizers can be used more efficiently at higher temperatures to produce good fertilizer effects. On the other hand, phosphorus fertilizers can increase the utilization of water in the soil and promote mutual promotion. The role. In addition, sufficient phosphorus can increase the utilization of nitrogen and play a role in raising nitrogen by phosphorus. In high-temperature and dry weather, the application amount of nitrogen fertilizer should be reduced, especially carbon-ammonia that is easily decomposed by heat, because carbon ammonia, which is easily decomposed by heat, and high-concentration nitrogen fertilizer, can easily cause crops to sprout. Fertilizer amount In high temperature and dry season, under the strong light, the temperature of bare ground can reach 50°C, the water evaporates strongly, 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 only be maintained or Increase production, and it is likely to reduce production. For example, when rainfall is moderate, the application of 12 kilograms of pure nitrogen per acre for maize may yield high yields, and if the same amount of fertiliser is applied at high temperatures and drought, it will face the risk of reduced production. Fertilizing time 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 to make up for the shortcomings of short crop absorption time (because the night is a process of decreasing temperature, evaporation of surface water is weakened, water retention time is long), so it is the best fertilization time .
