摘要
通过对黑龙江典型黑土区作物产量进行定位监测试验,以投影寻踪评价模型为手段,对气候因子与土壤因子耦合对玉米产量的定量影响进行研究。研究结果表明:在不同施肥方式处理条件下,有机肥+磷化肥的施肥方式对提高玉米产量的效果最佳。另外,对玉米产量影响较大的气候因子依次为:8月气温、5月降水、年降水、6月气温、7月降水、6月降水。所形成的结论可为有关部门科学制定东北黑土区农业综合开发对策提供依据。
Long - term monitoring trials to the crop yields of typical black soil area has been done and the affection of long - term fertilization on the yields of the crop which is widely be planted in northeast of China , such as corn , also has been evaluate in this paper. The results shown that the organic manure ＋ phosphate fertilizer could increase the corn yield. The factors that could influece the corn yields are： August temperature, May precipitation, Year precipitation, June temperature, July precipitation , June precipitation. The paper could provide basis information for science departments to develop comprehensive agricultural development in black soil zones of Northeast China.
