小麦属于对锌不敏感的作物。但近年来,国内外不少试验结果证明,在低锌土壤上施用锌肥小麦增产效果明显。据山东、河南省试验,小麦施锌增产机率超过80％,山西省、上海市小麦施锌增产机率超过60％。增产幅度一般为5—20％。有的高达30％以上。 1980年我所在保定的田间微区试验结果表明:施用锌肥能促进小麦生长发育,根系发达,叶大色绿,分糵增多.亩穗数增加2.1万,千粒重增加1.34 Wheat is a zinc-insensitive crop. However, in recent years, many domestic and foreign test results show that the application of zinc fertilizer in low-zinc soil increased yield of wheat significantly. According to the tests in Shandong and Henan provinces, the rate of increase of zinc application by wheat exceeds 80%, and the rate of zinc increase by wheat in Shanxi and Shanghai exceeds 60%. Yield increase is generally 5-20%. Some up to 30% or more. In 1980, the field experiment in Baoding city of our country showed that the application of zinc fertilizer could promote the growth and development of wheat, and the root system was developed, the leaves were large green color and the number of branches increased, the number of ears per mu increased by 21,000 and the grain weight per thousand increased by 1.34
