摘  要:
 通过对高肥力土壤肥料效应试验研究,结果表明:在速效钾含量380mg·kg-1的土壤上施用钾肥没有增产效应;速效氮含量126mg·kg-1、速效磷含量16mg·kg-1的高肥土壤上皮棉产量与氮磷化肥用量的效应方程为:Y=1195.6+1.11N+1.96P-0.001534N2-0.007359P2+0.003396NP,由此模拟最佳经济效益施肥为:尿素560.3kg·hm-2,重过磷酸钙为178.8kg·hm-2,最佳经济产量为1792.1kg·hm-2。

摘  要:
Result of this study indicated that potassium fertilization has no effect on increasing yields in (380 mg·kg~(-1)) available potassium soil. Available nitrogen 126 mg·kg~(-1) and available phosphorus, effective equation between the cotton yields and N,P fertilization quantities are as follows:Y=1195.6+1.11N+1.96P-0.001534N~2-0.007359P~2+0.003396NP,then the best economical fertilization quantities could be made:urea was 560.3 kg·hm~(-2),tri-phosphate was 178.8 kg·hm~(-2),the best economical yield of cotton was( 1 792.1 kg·hm~(-2)。)
