摘要
以"吉农15"为材料,研究了草甸黑土不同施钾量对大豆生长发育及产量和品质的影响。结果表明:钾能够促进大豆生长发育,增加叶片叶绿素、可溶性糖和蛋白质的含量。钾能够明显提高大豆产量,每公顷施钾200 kg,增产效果最明显,可增产25.14%。钾还能提高子粒脂肪含量,但蛋白质含量有降低的趋势。
Using jinong 15 as testing material,the effects of potassium application on growth and yield and quality of soybean in meadow black soil were studied.The results show that： potassium can promote the growth and development of soybean,and increase leaf chlorophyll,sugar and soluble protein content.Potassium can significantly increase soybean yield,and the most obvious yield increase occurs when potassium usage reaches 200 kg per hectare,increasing by 25.14%.Potassium can also improve fat content,but protein has a trend to decrease.
