| Notes | 44-1267/S In Huidong county, Huizhou city of Guangdong province, a field experiment was conducted in order to evaluate the effects of potassium sulphate, potassium chloride and combined application （ I ： 1 ） of them on the dry matter, tuber yield, quality and economical profit of winter potato, and to determine the feasibility of substitution of potassium chloride for potassium sulphate. Three treatments, potassium sulphate, potassium chloride, combined application （ 1 ： 1 ） of them were designed, with each treatment being replicated three times at random. The results showed that different fertilizer treatments had impacts on potato dry matter accumulation and each organ allocation rate of dry matter. The treatment order of starch and protein contents were as follows： potassium chloride 〉 combined application 〉 potassium sulphate, and potassium chloride 〉 potassium sulphate 〉 combined application, respectively. The yield of combined application treatment （ 60 914.83 kg/hm2 ） was significantly higher than that |
