摘要
通过３年田间试验，探讨了甜菜施用氯化钾的效果。结果表明：ＫＣｌ对甜菜增产效果稳定，在黑钙土和淡黑钙土区均表现较高的增产效果，其最高增产量分别为８．２％和１２．８％；ＫＣｌ对甜菜的增糖效果因土壤类型而异，在黑钙土区可增糖０．２２～０．３８度，但在淡黑钙区则表现出减糖效果；喷施ＫＣｌ并不增加甜菜Ｃｌ－含量，但可促进Ｎ、Ｐ、Ｋ的吸收；ＫＣｌ不但与Ｋ２ＳＯ４一样对土壤ｐＨ值无不良影响，而且在增产、增糖效果上表现出较优的趋势。
The effects of Potassium chloride on sugarbeet were studied for three years, the results showed that:the effect of KCl on root yield was relatively stable,comparing with controlling the highest increasement in chernozem and light chernozem could reach to 8.2% and 12.8%,respectively; The effects of KCl on Sugar content varied greatly as soil type changed,in chernozem it could increase sugar content in root to a range of 0.22%～0.38%,but in light chernozem a negative effect was demonstrated;A spray of KCl could stimulate the uptake of N、P、K, but the Cl- content showed little increasement in petide and root;The application of KCl had not only,as K2SO4,little harmful effect on soil pH,but also a trends of better effects on yield and sugar content than that of K2SO4.
