摘要
为探明红壤旱地玉米合理的有机和无机肥配合施用比例 ,采用田间小区试验对其进行了施用效果的研究 .结果表明 ,较合理的有机无机肥料配合施用比例为 2 5 %~ 5 0 %有机肥加 75 %~ 5 0 %化肥 .合理的有机与无机肥料配合施用可降低土壤容重 ,提高土壤含水量与土壤肥力 ,促进玉米生长 ,提高玉米籽粒产量和品质 .
In order to probe into reasonable ratio of application of inorganic fertilizer in combination with organic fertilizer of corn to red upland soil, the effects of application of inorganic fertilizer in combination with organic fertilizer to red upland soil were studied by using plot trial. The results are as follows: ①Reasonable application of inorganic fertilizer in combination with organic fertilizer obviously decreases soil bulk density,and increases moisture of soil and soil fertility, growth of corn and output, and promotes quality of corn grain.②The reasonable application ratio of inorganic fertilizer in combination with organic fertilizer is in the range of 25%~50% organic fertilizer +75%~50% chemical fertilizer .
