High temperature season is the fastest growing period of crops. At this time, fertilizers for crop growth must be sufficient. So, what are the methods and precautions for fertilizing in high temperature weather?
Fertilizer varieties
Apply more phosphate fertilizer. On the one hand, the phosphate fertilizer can be used more effectively at higher temperatures to produce good fertilizer efficiency; on the other hand, the phosphate fertilizer can improve the utilization rate of water in the soil and play a mutually promoting role. In addition, sufficient phosphorus can improve the utilization rate of nitrogen, and play the role of phosphorus nitrogen. Reduce the amount of nitrogen fertilizer applied, especially carbon ammonia which is easily decomposed by heat, etc., because the carbon ammonia which is easily decomposed by heat and high concentration of nitrogen fertilizer are easy to cause crops to burn seedlings.
Number of fertilizers
In the high temperature and dry season, under the strong light, the evaporation is strong, and the concentration of the surface water solution increases sharply. At this time, if the same amount of fertilizer is applied as in normal weather, the crop yield cannot be maintained or increased, and it is likely to be reduced. Reduce the amount of fertilizer applied.
Timely replenishment
Fertilization in high temperature seasons, especially when there is little water, if fertilization will cause the local soil solution concentration to be too high, because this time the temperature is high, the water evaporates quickly, if the water cannot be watered in time, the concentration after the fertilizer is applied is too high, then It will cause the pressure of local fertilization point to be too high, resulting in burning seedlings or burning roots. Especially for some crops, if fertilization is too close to the roots, it is very easy to cause dehydration of plants. At this time, it is too late to replenish watering, which will lead to a reduction in production. Therefore, fertilization in high-temperature weather should focus on soil moisture, timely supplement the water required by crops, and adjust the amount of fertilizer according to the moisture situation.
Evening fertilization is best
Grasp the fertilization time, the most suitable fertilization in the evening. In the morning fertilization, although the temperature is not high, it is more comfortable, but as the sun rises, the temperature rises sharply, the water is quickly evaporated, the crop absorption time is short, and the fertilizer utilization rate is low; fertilizing at noon, because of the high temperature, is not conducive to fertilizer Absorption and personnel operation; evening fertilization is suitable for personnel operation, and can make up for the shortcomings of crop absorption time (because night is a process of temperature reduction, surface water evaporation is weakened, water retention time is long), is the best fertilization time.
