In the recent period, the continuous low temperature rain and snow weather in the south has brought severe tests to the growth of rapeseed. Due to the continuous low temperature, the growth of many rapeseed seedlings has been stagnant or delayed, and the fields are caused by rain and snow. The phenomenon of widespread water accumulation also makes the root water absorption of rapeseed very poor. The most worrying thing is the low temperature and low light weather conditions, and the development of many talented buds is blocked, especially in many fields that have been twitching and flowering. Because the amount of flowering is reduced, the pods can not grow out, and people will often say The rat tail phenomenon will eventually lead to a reduction in the amount of rape. So recently, most of the southern rapeseed producing areas are facing a problem of how to deal with low-temperature rain and snow weather attacking rapeseed fields.

Today's rain is still in the eastern part of the southwestern region. There is still freezing rain in western Guizhou, and the lowest temperature here is below 0 °C. Tomorrow, a new round of large-scale precipitation in the south will start again. It is expected that there will be strong snowfall in some oilseed rape producing areas in southeastern Tibet, northwestern Yunnan and south of Yunnan, as in the south of Tibet, like Yunnan, Yunnan, Yunnan. There will be a large range of freezing rain in Guangxi and Jiangxi, and the temperature in the south will continue to fall in the next week, and it is obviously lower than that in the same period of the year. Therefore, the field management of rapeseed in the south cannot be relaxed.

It is suggested that these low-ranking rapeseed producing areas should be fertilized with straw fertilizer, grass ash, soil and other fertilizers, and continue to do warm and anti-freeze work. Reason.
