Several problems that should be paid attention to in field crop management such as single cropping rice

In the past week, the weather continues to be high temperature and strong light, the field evaporation is very large, part of Tiantian has appeared water shortage and drought. In the management of field crops such as single-cropping rice, we should pay attention to the following problems:

1. Medicine for disease prevention and pest control should be chosen in the morning and evening, and sufficient water should be used. At present, it is the suitable period for the control of leaf rollers and rice planthoppers in the fourth (2) generation of single cropping rice. when selecting corresponding pesticides for control, it is best to choose before 8 o'clock in the morning or after 5 o'clock in the evening to avoid the period of high temperature and strong light as far as possible. and use enough water to spray at least 4 knapsack water per mu (mobile sprayer not less than 2 knapsack water).

2. Water management in the field should pay attention to saving water, first using live water (ditch water, river water, etc.), and then using stagnant water (pond water, reservoir water, etc.), and be prepared to resist severe drought.

3. For open field watermelons, fresh corn and other crops that have been or are being harvested, we should seize the current favorable opportunity to plant high-yield crops such as japonica and glutinous rice in time, and try our best to plant high-yield crops such as rice in fields with water. If there is a shortage of water and seedlings, we should also plant other crops such as autumn corn, autumn soybeans or vegetables as soon as possible, so as to do everything possible to improve the utilization rate and yield of land so as to prevent seasonal abandonment.
