不同钾肥对马铃薯和胡萝卜产量及商品率的影响

采用大田试验方法,研究了不同品种钾肥(氯化钾和硫酸钾)对马铃薯和胡萝卜产量及商品率的影响。结果表明,与对照相比,施用氯化钾处理的马铃薯和胡萝卜每公顷产量分别增加了52.4%和46.4%,商品率分别增加了25.7%和42.9%;施用硫酸钾处理的马铃薯和胡萝卜每公顷产量分别增加了28.6%和17.9%,商品率分别增加了14.3%和31.0%。与不施钾肥处理相比,施用氯化钾与硫酸钾均能明显提高马铃薯和胡萝卜的产量及商品率,其中,施用氯化钾对于这2种作物的产量及商品率的提高效果较好。

Effect of Different Potassium Fertilizers on Yield and Commodity Rate of Potato and Carrot

A field experiment was carried out to evaluate the effects of potassium fertilizers KCl fertilizer and K2SO4 fertilizer on the yield and commodity rate of potato and carrot.The results showed as follows：In the KCl treatment,the yield per hectare of potato and carrot increased by 52.4% and 46.4% respectively,the commodity rate of potato and carrot increased by 25.7% and 42.9% respectively; In the K2SO4 treatment,the yield per hectare of potato and carrot increased by 28.6% and 17.9% respectively,the commodity rate of potato and carrot increased by 14.3% and 31.0% respectively.So,compared with the control of no fertilizer,the different types potassium fertilizers could significantly increase the yield and commodity rate of potato and carrot,and comparing with K2SO4,KCl increased more yield and commodity rate of potato and carrot.
