What are the precautions for spraying foliar fertilizer on rice?
Timing: Generally, spraying at the late booting, initial heading, grain-filling and full heading stages of early rice is most suitable, and spraying once per mu takes over an hour. If spraying fertilizer coincides with the heading and flowering stage, it should be done in the morning before the flowers open and after 4 p.m. Preparing liquid fertilizer: Various quick-acting nitrogen, phosphorus and potassium fertilizers, monopotassium phosphate, triacontanol, borax, silkworm droppings and human and livestock urine can all be used as foliar fertilizer. The amount used per mu is small, but they must first be processed into liquid fertilizer. Quick-acting chemical fertilizers should be dissolved in 5-10 times their amount of water the day before spraying to prevent burning the rice leaves from over-spraying.
