冬季大棚是一项高投入高产出的设施农业,搞好施肥管理是夺取棚菜增产增收的关键所在,但是由于去冬今春的阴雨多雪低温天气,造成了棚菜根系发育不良,甚至出现冻害,现在棚菜的生长又到了中后期,作物的根系又出现老化,再加上广大菜农习惯单独使用常规的化肥冲施追肥,造成了土壤板结严重,土壤通透性差,更加影响了作物的根系发育,影响了养分的吸收利用,造成肥料浪费,甚至变成化学有害物质,影响瓜菜的品质。针对上述问题,为了让农民朋友真正掌握科学种田技术, Winter greenhouse is a high input and high output of agricultural facilities, fertilizer management is to win the greenhouse yield increase key, but due to the winter rainy winter weather, resulting in poor growth of root vegetables, or even appear Frost damage, and now the growth of greenhouse vegetables has arrived in the late period, crop roots and aging, coupled with the majority of farmers accustomed to using conventional fertilizer Chong Shi top dressing, resulting in serious soil compaction, poor soil permeability, more affected the crop Root development, affecting the absorption and utilization of nutrients, resulting in waste of fertilizers, and even into chemical harmful substances, affecting the quality of vegetables. In response to the above problems, in order for farmers and friends to truly master the science and technology of farming,
