甜菜施用氯化钾对产量和含糖的影响

通过田间试验，土壤和甜菜叶柄，块根的化验分析，研究甜菜施用氯化钾的效应及ＣＬ＾－对土壤理化性状的影响，结果表明，在淡黑钙土上，施用氯化钾１５０～３００ｋｇ／ｈｍ＾２，甜菜产量提高４．６％～１２．８％；在黑钙土中施用氯化钾２２５～３００ｋｇ／ｈｍ＾２，含糖提高０．２２～０．３８度；根外追施０．４％浓度，产量提高１８．９％含糖提高０．０７度，氯化钾对甜菜增产，增糖的作用不亚于等Ｋ２Ｏ量的硫酸钾，甚至还

Affection on the Sugarbeet Yield and Sugar Content Using KCL

The paper discusses the effects of applying KCL to the sugarbeet and influence of CL-on the soil physico chemical properties,which is studied by means of the field test and the analyses of soil and sugarbeet petiole and root. The results show as follows. The sugarbeetyields increase 4. 6%~12. 8% when 150~300kg/hm2 KCL is applied to the lightish chernozem. The sugar content increase 0. 22~0. 38 degrees when 225~300kg/hm2 KCL is applied to the chernozem. when 0. 4%KCL solution is applied to the root adding,the yield increase 18. 9% and the sugar content increase 0.07 degree. The effect of KCL is equal or better than one of K2SO4 at the same amount K2O. When 0. 2 % and 0. 4% KCL solution is applied to the root adding,the CL- quantity in the sugarbeet petiole and root is not more than the critical and CK. The CL- has unharmful influence on the soil physico chermcal properties.
