甘薯是喜钾作物,施用钾肥能获得显著的增产效果。但是目前国内市场多为氯化钾,硫酸钾甚少,且氯化钾含钾量高价格又低,比施用硫酸钾合算。被称为忌氯作物的甘薯,是否能施用含氯化肥?能施用多少剂量?本工作在于探讨甘薯施用含氯肥料的可能性。一、材料和方法一、土壤质地为壤土,pH6.5。试验地为平地,起垄栽,土壤肥力基本一致。每小区0.05亩,扦插150株,四次重复,随机排列,采用定位试验,连续三年
Sweet potato is a potassium-like crop, the application of potassium can significantly increase yield. But at present the domestic market mostly potassium chloride, potassium sulfate is very small, and potassium chloride high price and low potassium, cost-effective than the use of potassium sulfate. Is it possible to apply chlorinated fertilizers to sweet potatoes known as chlorine-free crops and how many doses can be applied? This work explores the possibility of applying chlorine-containing fertilizers to sweet potatoes. First, materials and methods First, the soil texture of loam, pH6.5. Test for the ground, ridge planted, soil fertility are basically the same. Each plot of 0.05 acres, cutting 150, four times repeated, randomly arranged, the use of positioning test, for three consecutive years
