我们于1976—1978年在黑河流域绿洲潮土上的微肥试验已经证明:诸微肥中,锌肥对玉米、蚕豆和谷子籽粒产量的增加有良好的影响;而问题在于:锌肥若与钼肥混合施入时,钼肥对锌肥效果有增效作用;而锌肥若与铜肥混合施入时(硫酸锌中的硫酸铜杂质),铜肥对锌肥效果还有降效作用。为了确定钼、铜肥对锌肥效果的影响,为潮土区农业上合理施用微肥提供根据,我们在田间试验的基础上,于1981—1982年
Our micro-fertilizer experiments on alluvial soils in the Heihe River Basin in 1976-78 have shown that zinc fertilizers have a good effect on the increase of grain yield of maize, faba bean and millet in all the micronutrients; the problem is that zinc When molybdenum fertilizer is mixed and applied, molybdenum fertilizer has a synergistic effect on zinc fertilizer effect. When zinc fertilizer is mixed with copper fertilizer (copper sulfate impurity in zinc sulfate), the effect of copper fertilizer on zinc fertilizer is also reduced . In order to determine the effect of molybdenum and copper fertilizer on the effect of zinc fertilizer, it provided the basis for rational use of trace fertilizers in the agricultural area in Chao Soil Region. Based on the field experiments, in 1981-1982
