摘要
为探索微量元素肥料对玉米产量的影响,设置施用微量元素肥料试验,用量分别为硫酸亚铁30.0 kg/hm2、硫酸锰15.0 kg/hm2、硫酸铜7.5 kg/hm2、硫酸锌15.0 kg/hm2。结果表明:硫酸亚铁和硫酸锌2种微量元素对玉米产量影响最为明显,产量分别达到9 074.1 kg/hm2和8 765.4 kg/hm2,增产效果极其显著,说明赤水地区土壤中普遍缺铁和锌2种微量元素。
In order to explore the effects of trace element fertilizers on yield in corn production,by setting the trace elements fertilizer experiment,dosage of ferrous sulfate,manganese sulfate,copper sulfate and zinc sulfate was 30.0 kg/hm2,15.0 kg/hm2,7.5 kg/hm2 and 15.0 kg/hm2 respectively.The results showed that the effect of two kinds of trace elements of ferrous sulfate and zinc sulfate on the yield of maize was the most obvious,production reached 9 074.1 kg/hm2 and 8 765.4 kg/hm2,yield increasing effect was particularly significant.Two kinds of trace elements iron and zinc in soil of Chishui were generally deficient.
