- 摘要:
- 采用盆栽试验和田间试验方法, 研究了钾对大豆生理及产量和品质的影响。结果表明, 钾对大豆叶绿素、光合作用强度和硝酸还原酶有明显的正效应, 钾能显著提高大豆产量, 改善大豆品质。盆栽试验施钾增产7 .6 %～16 .9 %, 田间试验增产4 .1 %～14 .9 %。施钾具有提高大豆脂肪含量, 降低蛋白含量的趋势。
- Abstract:
- The effect of potassium on the phy siology , yield and quali ty of soy bean w as studied in pot and field experiments .The result show ed that potassium had a positive effect on the content of chlorophyll , the intensity of photosynthesis and the activity of nit rate reductase in soybean and a good effect on the yield and quality of soy bean .With potassium application , the yield of soybean increased by 7 .6 -16 .9 % and 4 .1 -14 .9 % in pot experiment and field experiment respectively .The application of potassium fertilizer had a posi tive effect on oil content and a negative ef fect on protein content of soybean .
