不同土壤类型/作物生育期决定了水溶肥料分施次数。设施蔬菜按作物养分吸收比例选择一般配方,再根据新老菜田调整P、K比例。如果冲施,低养分含量产品也可以用;如果滴施,则完全应用水溶性肥料,避免杂物堵塞滴头。对蔬菜生长和养分有效性来说,水分管理是支配因素。过量灌溉造成根区养分的淋失,这是增加养分投入的主要原因。设施蔬菜水肥一体化技
Different types of soil / crop growth period determines the number of sub-fertilization of water-soluble fertilizer. Facilities vegetables according to the proportion of crop nutrients to choose the general formula, and then adjust the new and old vegetable fields P, K ratio. If red, low nutrient content products can also be used; if the drop, then the full application of water-soluble fertilizer, to avoid debris clogging the dripper. Water management is the dominant factor for vegetable growth and nutrient availability. Over-irrigation caused by the root zone nutrient leaching, which is to increase the main reason for nutrient input. Facilities vegetable water and fertilizer integration technology
