To explore the effect of different types and dosages of potassium on quality and yield of garlic. Experiment using two types of potassium chloride and potassium sulphate.Set amount of potassium 75 kg·hm-2、150 kg·hm-2、225 kg·hm-2、300 kg·hm-2、375 kg·hm-2 5 horizontal processing,to zero K（CK）as a control. Physiology Indexes on garlic, quality indicators, garlic production, post-harvest residual soil available nutrient content were measured and analyzed, proved its effect on the garlic and soil. The results are as follows:1.Adequate rate of potassium fertilizer on the physiology of garlic a good indicator for effect. By potassium could promote garlic plant height, pseudostem diameter, bulb horizontal stems, plant dry weight and fresh weight increase; on the number of leaf pieces, chlorophyll content, root activity has some role in promoting.Can improve the quality of garlic, so that garlic Vc, soluble sugar, soluble protein content increased; Can greatly enhance the production of garlic, output increased by 22.2% 50.2%, the average yield 33.26%; The best facilities shoulder blade capacity 225 kg·hm-2. Appropriate amount of potassium can promote garlic nitrogen, phosphorus and potassium absorption and coordinate their absorption balance.2.Physiology of the garlic in the impact indicators, such as the amount of potassium sulphate potassium potassium chloride more than the promotion of plant height, pseudostem diameter, bulb horizontal stems, plant dry weight and fresh weight increase, the best deal for the 225 kg·hm-2, SOP; such as the amount of potassium chloride potassium tablets for the number of green leaves, chlorophyll content is better than potassium sulphate.3. Quality indicators on the impact of garlic, such as the amount of potassium sulfate potassium results slightly better than potassium chloride, but the difference was not significant. Application of potassium sulfate 225 kg·hm-2, the garlic Vc, soluble sugar content, and application of potassium sulfate 300 kg·hm-2, the highest content of soluble protein garlic.4.Garlic production areas to improve.So much better than potassium chloride of potassium sulphate.The former than the latter the average yield 4.61%.Application of potassium sulphate 225 kg·hm-2 ,the yield increased 50.2%.Garlic production reached its maximum.In addition to 375 kg·hm-2 levels, when the remaining amount of potassium was significant between the two.5.Post-harvest residues in the soil available nutrient level in.The amount of potassium sulfate and other potassium to promote the role of plant uptake of nitrogen than potassium chloride.Potassium content of potassium chloride and other plants absorb phosphorus to promote more effective than potassium sulfate.
