- 摘要:
- 研究了钾对高油大豆产量和品质的影响。黑龙江省大豆主产区钾肥适宜用量为45～90 kg/ hm~2，平均增产12． 7%，平均增收538元/hm~2。施钾肥具有降低蛋白质含量，增加脂肪含量的趋 势，粗蛋白含量平均降低1． 1个百分点，脂肪含量平均增加1． 4个百分点。在施等量钾肥情况下， 硫酸钾效果好于氯化钾。
- Abstract:
- Effect of Potassium on the Yield and Quality of High-oil Content SoybeanAbstract: This paper has dealt with the effect of potassium application on the yield and quality ofhigh-oil content soybean. The result showed that the optimum rate of potassium application forsoybean in the main region of soybean production in Heilongjiang province was 45～90 kg/hm2 , itcould increase the yield by 12. 7%, the benefit was 538￥/hmz , on average. With potassium ap-plication, it showed the tendency that protein content decreased and fat content increased; thecoarse protein content decreased by l. 1% and the coarse fat content increased by l. 4% , on aver-age. The effect of potassium sulphate was better than potassium chloride under the circumstanceof equal amount of Kzo application.
