不同类型土壤对小粒大豆生育及产量和品质的影响

Effects of Different Soils on Growth,Development, Yield and Quality of Small-Seed Soybean

以盆栽试验方式研究了暗棕壤、黑土、白浆土、黑钙土、盐碱土等不同类型土壤对小粒大豆生长发育、产量和品质的影响。结果表明:暗棕壤和黑土培育的小粒大豆在株高、植株鲜重、干物质积累、叶面积指数、根鲜重、有效根瘤数量等方面明显优于其他类型土壤。单株产量以暗棕壤培育的小粒大豆最高,达12.65g/株,黑土培育的小粒大豆次之,为12.32g/株。蛋白质含量、脂肪+蛋白质含量以暗棕壤培育的小粒大豆最高,为44.22％和59.93％。脂肪含量以白浆土培育的小粒大豆最多,达15.72％。黑土培育的小粒大豆脂肪+蛋白质含量为59.81％,仅次于暗棕壤。

Effects of different soils on growth and development, yield and quality of small-seed soybean through pot cultivating experiment were studied. The results showed that plant height, fresh weight, dry matter accumulation,leaf area index,fresh weight of roots and fresh active root nodules of small-seed soybean grown on dark brown soil and phaeozem were better than those of other soils remarkably. Yield per plant of small-seed soybean growing in dark brown soil and phaeozem was the highest of the five soils, 12.65 g/ plant and 12.32 g/plant respectively. Protein and oil + protein content of small-seed soybean from dark brown soil were the highest, 44.22% and 59.93% respectively. Oil content of small-seed soybean from albic was the highest, 15.72% . The oil + protein content of small-seed soybean from phaeozem was 59.81 % , just after dark brown soil.
