锌是农作物不可缺少的营养元素之一。国内外许多生产实践都表明,对于缺锌土壤施用锌肥,是提高农作物产量的重要措施之一。为了探索遵义地区锌肥效果和锌肥有效施用的条件。从1982～1985年我们组织了全区各县(市)的水稻、玉米施用硫酸锌(ZnSO_4·7H_2O)试验、示范、推广,已初步取得成果,受到广大农民的欢迎,现将试验结果总结如下:
Zinc is one of the indispensable nutrients in crops. Many domestic and foreign production practices have shown that the application of zinc fertilizer to zinc-deficient soils is one of the important measures to increase crop yields. In order to explore Zunyi zinc effect and effective zinc fertilizer application conditions. From 1982 to 1985, we organized the experiment, demonstration and popularization of zinc and zinc sulfate (ZnSO 4 · 7H 2 O) in rice and corn in all counties (cities) in the whole region, and achieved initial results and were welcomed by the vast farmers. The test results are summarized as follows :
