What are the technical measures for drought resistance and disaster mitigation in rice cultivation in Heilongjiang Province?
In response to the actual drought situation, the Rice Expert Guidance Group of the Ministry of Agriculture conducted in-depth research in drought-affected rice areas and proposed technical measures for scientific drought resistance and disaster mitigation to ensure increased rice production. 1. Strengthen the management and scheduling of irrigation water sources. Actively develop water sources, organize as much as possible the pumping of return flow and the use of water-lifting irrigation machinery to utilize rivers, lakes and groundwater, alleviating the contradiction of insufficient reservoir storage. For plots far from water sources, promptly dig supplemental water wells to ensure a safe water supply during severe drought seasons. Strengthen the management of existing water resources and the clearing, repair and film-mulching of main irrigation canals to prevent seepage and leakage. Scientifically regulate

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.
