Strengthen the field management of rice seedlings, plant and throw seedlings in advance. At present, the focus of seedling management is to prevent diseases and reduce dead seedlings.
The specific method is as follows: dry-raised seedlings can be sprayed with 600 times the proportion of dixone seedlings to prevent and control blight; Water seedlings can be raised on thin water to increase the mud temperature of the seedling field. For dry-raised seedlings with severe blight, measures should be taken to transplant the seedlings to the field as soon as possible. Starting from mid-April, when the seedlings have 4-5 leaves, they should be planted with mud, fertilizer and medicine to achieve large ears, many ears and high yield.
In April, the temperature was not stable enough, the cold wave was frequent, and the low temperature and cold wave were the main reasons for the stiff seedlings and dead seedlings in the field. Therefore, experts suggest that the management of field seedlings also needs to take measures to increase the temperature with water (that is, let the field irrigate and flood the seedlings) to promote the normal growth of seedlings; this year, the overwintering base of the borer is large, the incubation period of the borer is short, and the ant borer is born 8-10 days earlier than in previous years. Therefore, it is recommended that the prevention and control period should be carried out in April to early May.
In April, the field management of rice seedlings should be strengthened here, and I hope it will be helpful to everyone. If you want to buy high-quality and high-yield rice seeds, you can download the Seed Bank App, and the country's excellent rice varieties are available for everyone to choose.
