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

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 h...
