英国最近推出一种高浓度微量营养元素肥料,这是一种无硝酸盐的螯合物,适用于各种作物,尤适于现代化农业的集约栽培。这种肥料的元素比例为每公斤含锰90克,镁18克、锌、铜各10.4克、钼0.3克,因此,其浓度比常用者高100至750倍。为使其液肥被作物很快吸收,最适喷洒期有两次,第一次在作物生长 The UK recently introduced a high-concentration micronutrient fertilizer, a nitrate-free chelate that is suitable for a variety of crops and is especially suitable for intensive cultivation in modern agriculture. The fertilizer element ratio of 90 grams per kilogram of manganese, 18 grams of 18 grams of zinc, copper and 10.4 grams each 10.4 grams of molybdenum, therefore, the concentration of 100 to 750 times higher than those commonly used. In order for the liquid fertilizer to be quickly absorbed by the crop, the optimum spraying period is twice that for the first crop growth
