After the rice grows in the early stage, it enters the middle and late stages of reproductive growth. This stage is a crucial period for achieving high yields. The quality of field management directly affects the quality and yield of rice, and the focus is on pest control and water and fertilizer management.
1. Disease and pest control: rice is mainly caused by rice blast, sheath blight, and other diseases. Biological control technology is used to spray 800 times the new high-fat membrane and general tree maintenance. It is sprayed several times every 7-10 days to effectively prevent and treat diseases. Insect infection, sterilization and disinfection, improve the ability of rice to resist natural disasters, reduce residual toxicity, and environmental protection.
2, make-up application of grain fertilizer: the yellow color of the paddy fields, the appropriate application of granular fertilizer, generally about 25 kg of urea per hectare. At the same time, make appropriate foliar fertilizer to prevent premature plant failure after heading, use (new high-fat film diluent + strong spike), improve the utilization of active ingredients of medicinal fertilizers, prevent drought and prevent rain, strengthen the physiological function of rice, and enhance fruitfulness. Rate, increase grain weight, protect the healthy growth of rice.
3. Scientific irrigation: Before and after the heading date, it is the peak period of physiological water requirement in rice, and it is imperative that there is no water shortage, so as not to affect the differentiation and development of spikelets. Alternative wet and dry layer management methods should be adopted, and new high-fat film dilutions should be sprayed at the same time to improve soil ecological environment, increase root activity, and facilitate nutrient absorption and operation.
