摘    要:新疆滴灌棉花施用钾肥,灰漠土平均增产9 1%,草甸土平均增产6 6%。在适宜的氮磷肥条件下,灰漠土滴灌棉花最佳施钾量为94 5kg/hm2;草甸土滴灌棉花最佳施钾量为64 5kg/hm2。每公顷钾肥用量增加1kg,灰漠土棉株体内全钾含量提高0 006029%;草甸土棉株提高0 004457%。钾肥施用方法以基施配合滴施最佳。

关 键 词:棉花滴灌  钾肥  施肥技术

Abstract:In Xinjiang,using potash fertilizer for drip irrigation cotton,on desert grey soil average increasing yield 9.1% and meadow soil average increasing yield 6.6%.Under the suitable condition of nitrogenous-phosphate fertilizer,using potash fertilizer the best amount of drip irrigation cotton on desert grey soil is 94.5kg/hm~2 and for meadow soil is 64.5kg/hm~2.For per hectare,the usage amount of potash fertilizer increases 1kg,whole potash content in stem of cotton on desert grey soil raises 0.006 029% and stew of cotton on meadow soil gains 0.004 457%.It is the best way for using potash fertilizer to basic use with drip use.
Keywords:drip irrigation for cotton  potash fertilizer  applying fertilizer technology
