At present, large areas of rice are maturing one after another, and all localities must rush to catch up with rice harvesting. At the same time, they should also pay attention to the work of retaining and storing ratooning rice.
Bud-promoting fertilizer is a key measure to obtain stable and high yield of ratooning rice. Therefore, adequate bud-promoting fertilizer should be applied 10-15 days before the harvest of the first season, 15 kg 50% BB fertilizer per mu or 15-20 kg urea per mu . When harvesting, you should look at the buds in the first season and ensure the height of the pile. Generally speaking, when the whole field has more than 95% of the grains yellow and 70% of the plant's second and third buds are more than 2 cm long, the harvest is appropriate. The height of the pile can be maintained at 33-40 cm, and the dormant buds from the first two nodes will become ears to increase the rate of regenerated ears.
After the first season rice is harvested, it is necessary to cover the rice straw between the rows of rice stubs immediately, which can not only reduce field water evaporation, maintain soil moisture, resist drought and protect seedlings, promote the growth of regenerated shoots, but also increase the potassium nutrition of the soil and improve soil fertility. In case of continuous sunny and high temperature weather or lack of water in the rice field, you should pay attention to watering in the evening on the day of harvest and the morning and evening two days after the harvest, or pour the rice pile with clean manure water to reduce temperature and increase humidity, protect buds and promote seedlings.
