How to use low-temperature weather

The cold weather in autumn and winter is a problem. How to use low-temperature weather is a problem. Some fertilizers can be directly absorbed by crops after they are applied to the soil. Some can't. Increasing phosphorus and zinc fertilizers can effectively enhance the ability of plants to resist freezing. Therefore, it is necessary to make full use of natural conditions and apply scientific fertilization according to the characteristics of fertilizers. We must not blindly apply fertilizers and affect crop growth.

When the temperature of suitable ammonium bicarbonate is low, ammonium bicarbonate is not easily decomposed and it is beneficial to improve fertilizer utilization. Ammonium bicarbonate belongs to ammonium nitrogen fertilizer and can be directly absorbed and utilized by crops after being applied to the soil. The fertilizer has a rapid effect and belongs to a typical “quick-effect fertilizer”. It can provide nitrogen nutrition to crops in time. Some people have done experiments, ice and snow temperature during the topdressing of ammonium bicarbonate in the wheat field, its effect is higher than the application of high temperature season 1 to 1.5 times.

Avoid application of urea urea belongs to ammonium ammonium fertilizer, can not be directly absorbed by the crop after application into the soil, need to be converted into ammonium nitrogen under the effect of urease secreted by urea bacteria in the soil for root absorption. The rate of urea conversion mainly depends on the soil temperature at that time. Normally, the urea applied to the soil is converted to ammonium nitrogen. It takes 7 to 10 days for the ground temperature to reach 10°C, and 4 to 5 days for the temperature to reach 20°C. Only takes 2 to 3 days at 30°C. If urea is used, the growth of the crop will be affected by the slowness of the fertilizer effect.

The application of phosphorus and zinc fertilizers to the absorption of phosphorus and zinc is significantly affected by temperature and light. In autumn and winter, low temperatures and lack of light can easily induce phosphorus and zinc deficiency in overwintering crops. Phosphate fertilizer and zinc fertilizer should be added appropriately. In addition, phosphorus can enhance the cold resistance of plants, and the increase of phosphate fertilizer also helps prevent crops from freezing.
