Recently, the reporter learned from the Central Meteorological Observatory that before the end of January, the temperature in most parts of central and east China is still low. Rain and snow weather will also occur in the south and it is imperative to do a good job in agricultural disaster prevention in advance.
After entering this year in January, China’s central and eastern regions have suffered two rain and snow cooling processes in some areas of agricultural disaster, especially in southern provinces, such as the collapse of greenhouses and other disaster situations. Relevant meteorologists explained that after January, the conditions for transporting water vapor in the south have turned better. The warm and humid air flow from the Bay of Bengal is very strong. Warm and humid air enters our country from the southwest and meets the weak cold air south of the north. A wide range of central and eastern rain and snow formation.
Due to the rainy and snowy weather in many southern provinces in late January, the meteorological experts warned that in the aspect of agriculture, the snowfall process will benefit soil moisture in the northern winter wheat area and maintain soil moisture, which is very beneficial to the wintering winter wheat. However, heavy snowfall may adversely affect the agricultural production of facilities and may cause some greenhouses to collapse. Heavy rainfall in the southeastern part of Jiangnan and northern part of South China may cause some water logging disaster in some low-lying farmland. In addition, after the snowfall, temperatures in the Huanghuai, Jianghuai and Jianghan areas are rather low. Winter vegetables and rapeseed with weak vegetables and facilities may suffer frost damage. Large areas of southern Jiangnan, southern China and eastern Yunnan have a large temperature drop, which is not conducive to facility agricultural production And open-field vegetables, economic fruit and other growth, some areas may suffer from cold damage.
To this end, experts suggest that rainfall in southern areas should pay attention to rainfall and timely sowing soil moisture, reduce field humidity and reduce the impact of wet injury to ensure the robust growth of rape and winter wheat. At the same time, before the arrival of cold air, do a good job in cold and frost work for the open field of vegetables, crops and straw can be covered with a thin film, the application of thermal fertilizer and other measures to improve frost resistance, fruit trees can take base soil, trunk dressing, orchard smoked Smoke and other measures cold and frost, greenhouses pay attention to greenhouse shed plastic cover work to reduce the adverse impact of cold air.
