近期,我国北方大部地区持续阴雪、雾霾天气,低温寡照给设施蔬菜生产带来不利影响。为减轻灾害性天气对设施蔬菜生产的影响,降低菜农损失,农业部蔬菜专家指导组研究提出阴雪、雾霾天气设施蔬菜生产管理技术指导意见。增强植株抗逆能力增施有机肥,适当补充有机物料和叶面肥。施肥量应根据土壤的供肥能力和目标产量的需肥量来确定,通常土壤供肥能力 Recently, most parts of northern China continue to have adverse impacts on the production of facilities such as snow, fog, haze and low-temperature oligosols. In order to reduce the impact of disastrous weather on the production of vegetable production and reduce the losses of vegetable farmers, the vegetable expert guidance group of the Ministry of Agriculture has put forward the technical guidance on the vegetable production and management of snow, snow and haze weather facilities. Enhance the resilience of plants by adding organic fertilizer, appropriate organic material and foliar fertilizer. The amount of fertilizer should be based on soil fertility and target yield to determine the amount of fertilizer needed, usually for soil fertility
