Abstract

Abstract:

【Objective】 To investigate the effects of potash fertilizer distribution and dosage in cotton production and clarify the most suitable potassium application level for cotton growth under drip irrigation under membrane in Xinjiang. 【Methods】 Four potash dosages were set, i.e., 60, 90, 120 and 150 kg/hm² of pure potassium (K₂O), which were expressed as K₁, K₂, K₃ and K₄, respectively; and two kinds of potash fertilizers, i.e., potassium sulphate and potassium sulphate+potassium humate (1:1 ratio), which were expressed as A and B, with eight treatments in total, and no potash fertilizers were applied to CK as the control. 【Results】 The experiment showed that plant height of cotton in all treatments was greater in AK₄ treatment, but not significantly different from BK₄. Stem thickness reached the maximum in BK₄ treatment, but there was no significant difference with AK₃, AK₄ and BK₃;SPAD value showed a trend of increasing and then decreasing in each treatment, and reached the maximum in AK₄ treatment in the boll stage, but there was no significant difference with AK₃, BK₃ and BK₄; Dry matter accumulation increased slowly and then rapidly with the progress of fertility, and reached the maximum at the full-bell stage, and the dry matter accumulation of BK₄ treatment was the highest among all treatments, but there was no significant difference with AK₃, AK₄ and BK₃; Intercellular CO₂ concentration and net photosynthetic rate at the boll stage increased with the increase of fertilizer application, and transpiration rate and stomatal conductance decreased and then increased with the increase of fertilizer application. The seed cotton yield of both potash treatments increased with the increase of fertilizer application, and the BK₄ treatment had the highest yield, but there was no significant difference with AK₃, AK₄ and BK₃. 【Conclusion】 Considering the factors together, potassium sulfate compounded with potassium humate treatment is superior to potassium sulfate treatment alone, and BK₃ treatment is the best treatment.

摘要：

【目的】探究钾肥配施和用量在棉花生产中的效果,分析适宜新疆膜下滴灌棉花生长的施钾水平。【方法】设置4个钾肥用量,即纯钾(K₂O)60、90、120和150 kg/hm²,分别以K₁、K₂、K₃和 K₄表示;设2种钾肥,即硫酸钾、硫酸钾+腐植酸钾(1∶1配比),分别以A和B表示,共计8个处理,不施钾肥CK为对照。【结果】各处理棉花株高在AK₄处理较大,但与BK₄无显著差异。茎粗在BK₄处理下达到最大,但与AK₃、AK₄和BK₃之间无显著差异;SPAD值各处理呈先增加后降低的趋势,结铃期中AK₄处理达到最大值,但与AK₃、BK₃和BK₄间无显著差异;干物质积累随生育期进程推进先缓慢增加后迅速增加,在盛铃期达到最大,各处理中BK₄处理的干物质积累最高,但与AK₃、AK₄和BK₃间无显著差异;花铃期胞间CO₂浓度、净光合速率随施肥量的增加而增加,蒸腾速率和气孔导度随施肥量的增加先降低后增加。2种钾肥处理籽棉产量均随施肥量的增加而增加,BK₄处理产量最高,但与AK₃、AK₄和BK₃间无显著差异。【结论】硫酸钾复配腐植酸钾处理优于单施硫酸钾处理,BK₃处理为最佳处理。
