What issues should be paid attention to in the management of single-season rice and other field crops

In the past week, the weather has continued to be hot with strong sunlight, field evaporation has been very high, and some rainfed fields have already experienced water shortage and drought. In the management of single-season rice and other field crops, attention should be paid to the following issues:

1. Spraying for disease and pest control should be done in the morning and evening, and sufficient water should be used. At present, it is the suitable period for controlling the fourth (2) generation leaf roller and rice planthopper of single-season rice. When selecting appropriate pesticides for control, the spraying time should preferably be before 8 a.m. or after 5 p.m., avoiding the high-temperature and strong-sunlight period as much as possible, and sufficient water should be used, with at least 4 backpack sprayer loads of water per mu (no less than 2 backpack sprayer loads for a motorized sprayer).

2. In field water management, attention should be paid to saving water. Use flowing water first (ditch water, river water, etc.), then use still water (pond water, reservoir water, etc.), and be mentally prepared to resist major drought.

3. For open-field watermelons, fresh-eating corn, and other crops that have already been or are being harvested, seize the current favorable opportunity to promptly plant high-yield crops such as japonica rice and glutinous rice. For fields with water, plant high-yield crops such as rice as much as possible. If there is a shortage of water and also a shortage of seedlings, promptly plant other crops such as autumn corn, autumn soybeans, or vegetables as early as possible, and do everything possible to improve the land utilization rate and output rate, and prevent seasonal abandonment of farmland.
