水稻缺锌研究,近十多年来进展较快,国外如印度、菲律宾、日本等在这方面的报道逐渐增多,国内安徽、山东、云南、四川等省也已开始研究。我省江北农场1976年中稻“691”施用锌肥取得较好增产效果;1977年我们协同沔阳、天门、监利、竹山、均县、襄阳等县,荆州、襄阳、孝感、郧阳等地区农科所,沙洋农场农科所、东西湖农场农科所等开展水稻等施锌试验,大都取得较好效果。试验方法以小区试验为主,结合砂培及微区同位素示踪。现将全省有关试验结果综合整理如下。
Research on zinc deficiency in rice has progressed rapidly in recent ten years. Reports from foreign countries such as India, the Philippines and Japan have been gradually increasing in this area. Other provinces such as Anhui, Shandong, Yunnan and Sichuan have started to study. In 1976, we cooperated with other local farmers such as Shenyang, Tianmen, Jianli, Zhushan, Junxian and Xiangyang counties, Jingzhou, Xiangyang, Xiaogan, Yunyang and other regions Branch Office, Shayang Farm Agricultural Institute, East Lake Farm Agricultural Science Institute to carry out rice and other zinc test, most achieved good results. The test method is mainly plot test, combined with sand culture and micro-region isotope tracing. Now the province’s test results are summarized below.
