How to prevent and control rice red blight? These 4 methods work fast
After good early growth, rice enters the reproductive growth stage of the middle and late periods. Strengthening field management at this stage has a great relationship with the yield and quality of rice. So, how can field management in the middle and late stages of rice growth be done well? 1. Timely field drying. Field drying should generally be carried out when rice is not sensitive to water reaction, that is, it is more suitable from the late tillering stage to the early young panicle differentiation stage. The following principles should be followed during operation: fields with sufficient and vigorous seedlings should be dried appropriately earlier; where the mud foot is deep and there is excessive growth, drying should be heavier, otherwise lighter; fields with poor water retention should not be dried heavily; saline-alkali paddy fields generally cannot be dried.
