摘要
依据水稻作物的需肥特点和盐碱土壤的供肥特性 ,配制和使用锌钾专用肥料 ,较一般的施肥方式更具有科学性和针对性 ,也拥有更高的经济价值。试验、示范表明 ,可使水稻增产 15 .4%~ 2 0 .9%,投入产出比值达 1∶ 6 .2~ 11.3,对提高缺钾少锌地区水稻产量具有现实意义。
According to the special needs of rice for fertilizer and the characteristic of saline or alkline land,used the fertilizer compounded of zinc and potassium on rice production.The result showed that the yield of rice increased 15.4%~20.9%,the ratio of input to output reached 1∶6.2~11.3.Using compound fertilizer has pratical significance to increase yield of rice in the area with less zinc and potassium.
