浙东沿海水田,土壤属滨海淡塘泥土,土质粘重,由于土壤严重缺锌,制抑水稻产量的提高。我们于80年代开始进行土壤含锌量测定与水稻施锌增产效果、使用方法等试验,通过试验示范,证明沿海淡塘泥田施用锌肥是一项低成本高效益的增产技术。此项技术已为广大农民所接受,取得显著的社会效益和经济效益,现根据试验结果将沿海淡塘泥田水稻施锌肥的效益和使用技术归纳如下:
East Zhejiang paddy field, the soil is a coastal pond light soil, soil sticky, due to a serious lack of zinc in the soil, the inhibition of rice yield increase. In the 1980s, we started to measure the amount of zinc in soil and the effect of increasing the yield of zinc in paddy rice. The experiment and demonstration showed that the application of zinc fertilizer in coastal freshwater ponds is a low-cost and high-efficiency stimulation technology. This technology has been accepted by the majority of farmers, and achieved significant social and economic benefits, are based on the test results will paddy rice coastal paddy fields Zinc benefits and use of technology are summarized as follows:
