[0008] A method to prevent rice from sitting or stiff seedlings is mainly to apply zinc fertilizer during the growth period of rice by the common methods of basal fertilizer, topdressing, foliar spraying, seed soaking, and seed dressing. The zinc fertilizer can be agricultural zinc sulfate. such as:
[0009] 1. Apply basic fertilizer, about 1.5 kg of zinc fertilizer per mu, and apply it when the land is cultivated;
[0010] 2. Foliar spraying, spraying once at the seedling stage and tillering stage of rice, 50 kg of 0.1-0.3% zinc sulfate solution per mu each time, can effectively prevent the "stuffy" and "stiff seedlings" of rice caused by zinc deficiency .
[0011] Spraying the above dose of zinc fertilizer during the fouling period can also increase the seed setting rate of rice. The records of many experiments show that if the zinc fertilizer is sprayed three times in the rice lifetime, it can increase the rice yield by about 10%.
