Use urea, ammonium bicarbonate, ammonia to kill insects. All three ammonia fertilizers have strong volatility and have irritating, corrosive and fumigating effects on pests. In particular, control effects are particularly good on spiders such as spider mites, leafhoppers, aphids, and thrips, which have small size and weak endurance.

Use Pesticides to kill and sterilize. Spraying cotton with 2% superphosphate solution can drive away spawning bollworms and kill cotton spider mites, cockroaches and other pests. Spraying tomato with 1% of superphosphate also has a significant effect on preventing umbilical rot.

Preservative calcium storage

After the end of autumn and winter sowing, the calcium sulphate in some peasant households was not used up, and they were thrown arbitrarily in one place. They intended to use it again in the spring of the following year. The used calcium sulphate should be tightly and tightly fastened in a timely manner to keep the fertilizer bag intact. Do not put it outdoors in a place where it is prone to rain, or place it outside in the corridors, places where humans and animals pass, so as not to walk through the bag and get damp. It should be placed indoors, requiring good indoor ventilation, no leakage, and dry ground. It is best to lay a layer of moisture-proof linoleum or wood on the mat. If the manure bag has been broken, it is best to replace it with a paper manure bag that has not been damaged, refit it, and secure it tightly and securely.

Nitrogen fertilizer: nitrate or ammonium

Nitrate nitrogen fertilizer and ammonium nitrogen fertilizer nutrients in both forms are easily absorbed by crops. However, the application of nitrate nitrogen fertilizers into paddy fields and sandy lands tends to be leached out with water. In the paddy fields, it will also become loss of gaseous nitrogen. It is advisable to use nitrogen fertilizers in the early spring to apply fertilizers and dryland fertilizers. Ammonium nitrogen fertilizer is not easy to leach, and can be used in dry fields and paddy fields, but it is easy to decompose when alkaline substances are encountered. Therefore, it is necessary to emphasize deep-buried soil.
