| 摘 要： | 试验结果表明,供试土壤缺钾是蕹菜生长的主要养分限制因子之一。单施有机肥无法满足蕹菜高产栽培的养分供给;在NP基础上施钾肥增产155 13%;有机-无机肥料配合施用,比单施化肥处理的增产8 57%,比单施有机肥处理的增产110 65%;蕹菜对氮、磷、钾养分的吸收率显著提高。

| Abstract: | The experimental results indicated that tested soil is poor in potassium, it is one of factors limiting water spinach yield, there was not enough nutrition if only manure was applied on water spinach. The application of potassium increased water spinach yield by 155.13% , over NP treatment, the manure was combined with chemical fertilizer the yield was increased by 8.57% and 110.65% than the treatment with chemical fertilizer and treatment with manure only, respectively. The N, P, K nutrition was absorbed by water spinach was increased. |
