| 摘 要： | 应用"土壤养分状况系统研究法"对吉林省202个土壤样品化验分析和生物诊断.结果表明,土壤缺钾位序由70年代的N、P、Zn、K演变为N、K、Zn、P,钾肥在我省春玉米的平衡施肥中起着重要作用;各品种玉米对土壤和肥料中钾素的敏感程度不同,吸收钾的数量差异悬殊.钾肥在不同类型土壤上对玉米增产数量有较大差异,在黑土上增产15.1%,淡黑钙土上增产20.4%,风沙土上增产38.8%.试验还得出了土壤中速效钾含量与施钾最大增产量呈极显著的直线负相关(y=3491.5-23.0X)。

| Abstract: | The 202 soil samples were analyzed and diagnosed by using the systematic research method of soil nutrient condition .The result showed the deficient order of the potassium in the soil has turned to N, K, Zn, P from N, P, Zn, K in the 1970s. Potash fertilizer plays an important role in the balanced fertilization on spring maize in Jilin province. The sensitivity of different variety maize to potassium in the soil and fertilizer were not the same and the amounts of potassium absorbed by them was great difference. There was great difference on yield increase amounts to maize for potash fertilizer on different type of soil and it increased yield by 15.1% on the black soil, 20.4% on the light chernozem soil and 38.8% on the aeolian sandy soil. From the experiment we also drew the conclusion that there was the most significantly negative linear correlation between available potassium content and the maximum yield increase amounts of applying potash fertilizer. |
