据邱任谋研究,土壤速效钾含量在150ppm以下和施用适量的氮肥及磷肥的基础上,增加钾肥,有明显的增产效果与改进纤维品质的作用。蕾铃脱落率降低3.6—15.1％,单株成铃增加1.5—3.2个,单铃重提高0.2—0.5克,衰退期推迟15—18天,亩产增加11—14.9％,而且霜前花提高2.5—6.3％,纤维长度增长0.6—1毫米,衣指增加0.2—0.5克,纤维强度增
According to Qiu Renmou study, the soil available potassium content below 150ppm and the application of appropriate amount of nitrogen and phosphate based on the increase in potassium, a significant increase in yield and improve the role of fiber quality. Falling percentage of buds decreased by 3.6-15.1%, bolls per plant increased by 1.5-3.2, boll weight increased by 0.2-0.5g, postponed for 15-18 days, increased by 11-14.9% per mu and increased before frost 2.5-6.3%, 0.6-1 mm increase in fiber length, 0.2-0.5 g increase in finger, fiber strength increased
