酥梨增施钾肥的３年定位试验证实，在酥梨生长的中、后期（６、７月），追施钾肥（硫酸钾或氯化钾）２次，每公顷施Ｋ２Ｏ３７５ｋｇ情况下，酥梨的叶片和果实Ｎ、Ｐ、Ｋ含量及总吸收量明显增加，果实固形物、可溶性糖含量、单果平均重和Ｖｃ含量等明显提高。同时，梨果产量增加２３．７％～２２．４％，每公顷施钾纯增产值达２．２５万元，施钾产投比为１４．７～２７．２∶１。在施用有效成分（Ｋ２Ｏ）相等的情况下，硫酸钾和氯化钾的施用效果相近。但因氯化钾肥价格低，含钾量高，故实际经济效益和产投比明显高于硫酸钾
Pear increased application of potash 3 years positioning test confirmed that pear growth in the late (6, July), topdressing potash (potassium sulfate or potassium chloride) 2 times per hectare Shi K20375kg case, pear The content of N, P, K and total absorption of leaves and fruits significantly increased, and the content of solid, soluble sugar, average weight of single fruit and Vc increased obviously. At the same time, the output of pear fruit increased by 23.7% -22.4%. The pure output value of potassium per hectare reached 22,500 yuan, and the investment ratio of potassium output was 14.7-27.2: 1. In the case of the same active ingredient (K2O), the application effect of potassium sulfate and potassium chloride is similar. However, due to the low price of potassium chloride fertilizer, potassium content is high, so the actual economic benefits and production / investment ratio was significantly higher than potassium sulfate
