Hubei timely clears snow in crop greenhouses, heats up and heats up to prevent freezing damage
In mid-January, wheat and rapeseed in Hubei Province were in the wintering period. The average temperature in most areas of the province was low. The low temperature rain and snow caused the snow in most parts of eastern Hubei and southern Jianghan Plain to exceed 5cm, causing some vegetable greenhouses to collapse, the leaves of rapeseed were frozen and wilted, and the alpine tea trees in some areas were frozen; Vegetables have different degrees of freezing and freezing. According to the statistics of the Civil Affairs Department, the rain and snow from 16 to 20 caused 39.15 thousand hectares of crops in 16 counties such as Xianning, Huanggang, Yichang, Xiaogan and Xiantao, including 3.46 thousand hectares.
It is expected that there will be two rain and snow weather in the second half of this month; the pre-week period is weak, and the temperature in the middle and late period continues to be low. The amount of rain and snow in our province is close to normal in the same period of the year, with 5-10 mm in the northern region and 10-15 mm in the southern region. The average temperature in the past is slightly lower than the normal period, and most of the region is 1 to 4 °C. Extreme minimum temperature: -8 to -5 °C in the north - 4 to -1 °C in the south.
Agricultural advice:
1. Greenhouse greenhouses should timely remove snow from crop greenhouses to avoid collapse; take measures such as strengthening scaffolding, thickening cover and artificial heating to keep warm and prevent freezing damage.
2. Immediately after the occurrence of rape damage, the frozen leaves and moss parts should be removed, and a small amount of quick-acting fertilizer should be applied to restore the growth and reduce losses.
3, citrus orchards, tea gardens should strengthen the winter tube, do a good job of insulation and antifreeze.
