The rainy season is over. According to the forecast of the Provincial Meteorological Observatory, it has been sunny, hot and high temperature in the near future. Due to the high field humidity in the early period, the high temperature and high humidity field microclimate conditions, it is very easy to cause the rapid growth and spread of crop diseases and insect pests on the ground. Suffered severe flooding, in view of the actual situation in the field, we suggest:
Rice
The flooded rice fields should be drained as long as the core leaves of the seedlings spit water in the morning, these seedlings can still be saved. Drainage can not be completely drained, keep 3-5 cm shallow water to prevent high temperature flash seedling loss caused by water loss.
After drainage, first spray some high-quality foliar fertilizers and plant endogenous regulators, while topdressing 5-7.5 kg/mu of urea.
Dryland crops
After the weather is clear, the flooded fields must be deeply opened three ditches to eliminate the flooding. While preventing diseases and insects, add high-quality foliar fertilizer Huilongbao or Universe Star for spraying; pay close attention to weak seedlings and fields lacking fertilizer Fertilizers; at the same time this year, peanuts, corn, sesame, soybeans and other dry crops have serious diseases and insect pests, so we must do a good job of preventing and controlling roads.
Flood and drought crops
In the areas south of the Huaihe River, rush to sow fresh sweet waxy corn, choose varieties with a short growth period (80-90 days), and finish sowing before August 10. The planting benefits are still considerable.
At the same time, you can also plant mung beans, buckwheat, late autumn crops with a short growth period; if the water cannot be retreated in time, the replanting cannot be completed before the 10th of this month, and summer and autumn vegetables can be prepared for planting.
At present, vegetable prices are relatively high, so we can sow vegetables to make up for the loss, so that we can use autumn to supplement summer.
