江苏里下河地区农科所、扬州市土壤肥料站与邗江县化工厂联合研制和试验推广了微量元素肥料新品种——多效锌肥。原料是利用邗江化工厂生产氧化锌的副产物加工而成。产品为粉末状、不潮解,含有锌10～12％、铜0.3％、锰0.05％等。锌是作物体内一些酶的组成部分,它与作物的光合作用、吸收作用等有关。它可促使植物生长素的合成,使得作物叶色浓绿、叶面增加,增强抗寒、抗病能力,可
Jiangsu Lixiahe Agricultural Science Institute, Yangzhou soil fertilizer station and Qijiang County Chemical Plant jointly developed and tested the promotion of a new trace element fertilizer varieties - multi-effect zinc fertilizer. Raw materials is the use of Qijiang chemical plant production of zinc oxide by-products processed. Products for the powder, not deliquescence, containing 10 to 12% zinc, copper 0.3%, manganese 0.05% and so on. Zinc is part of the body of some enzymes in the crop, which is related to crop photosynthesis, absorption and so on. It can promote the synthesis of auxin, making crop dark green color, increased foliar, and enhance the resistance to cold and disease resistance, can
