摘  要：
【目的】通过田间小区试验,研究硫酸钾镁肥在新疆葡萄上的应用效果。【方法】氮、磷肥用量相同的基础上,在新疆葡萄上施用不同用量的硫酸钾镁肥,探讨葡萄产量、品质及经济效益与钾肥的关系。【结果】施用硫酸钾镁肥能够提高葡萄单粒重,显著增加葡萄产量,OPT-1/2K、OPT、OPT+1/2K和OPT+K处理分别比OPT-K处理增产11.64%、19.95%、3.08%和1.58%。施用不同用量的硫酸钾镁肥后葡萄品质均得到改善,葡萄可溶性固形物和可溶性总糖都有所提高。硫酸钾镁肥施用量在0~818.25 kg/hm2,肥料贡献率随硫酸钾镁肥施用量的增加而提高,当硫酸钾镁肥施用量大于818.25 kg/hm2时,肥料贡献率随硫酸钾镁肥施用量的增加而大幅度降低。从经济施肥角度考虑,葡萄最佳经济产量施钾量为604 kg/hm2。去除肥料投入,OPT处理增收效果最好,纯收益达到了11 382元/hm2,其次是OPT-1/2K处理,纯收益为6 780元/hm2,而OPT+1/2K处理和OPT+K处理较差,葡萄增产却没有达到增收的效果。【结论】硫酸钾镁肥施用量为818.25 kg/hm2时,可显著提高葡萄产量,改善品质,增加经济效益。

摘  要：
【Objective】The purpose this project is to study effects of applying sulphate- potassium magnesium fertilizer on grape through plot field experiment. 【Method】Exploring the different amount of sulphate- potassium magnesium fertilizer on the grape yield,quality and economical benefit when the phosphor amount remained the same. 【Result】Appling sulphate- potassium magnesium fertilizer could improve grape single fruit weight,and significantly increased grape yield. OPT- 1 /2K,OPT,OPT + 1 /2K and OPT + K treatment separately increased the yields by 11. 64%,19. 95%,3. 08% and 1. 58% compared with the OPT- K treatment. Grape quality was improved after applying different amount of sulphate- potassium magnesium fertilizer and soluble solids and total soluble sugar were increased. The contribution rate of fertilizer increased with theincrease of sulphate- potassium magnesium fertilizer in 0- 818. 25 kg/hm2,and the contribution rate of fertilizer obviously was reduced with applying sulphate- potassium magnesium fertilizer which was more than 818.25 kg/hm2. Concerning on the optimum economic efficiency,the optimum commercial efficiency application rate of nitrogen fertilizer was 741 kg/hm2. Removal of fertilizer inputs,OPT treatment had the best effect and net income reached 11 382 yuan/hm2,followed by OPT- 1 /2K,whose net income was 6 780 yuan /hm2,OPT+ 1 /2K and OPT + K treatments were poor,and the grape production did not achieve the effect of increasing their income.【Conclusion】Sulphate- potassium magnesium fertilizer of 818. 25 kg/hm2 could obviously the grape yield,improve the quality and increase the economical benefit.
