摘要: 试验旨研究窄行密植免耕对大豆根系特性、产量及品质的影响。试验设置3个处理,30 cm 窄行免耕、19 cm窄行免耕和68 cm传统垄作,分别用NT1、NT2和CT表示。研究结果表明,NT1和NT2单株根系干重、鲜重显著低于CT处理,但是群体根系干重、鲜重却显著高于CT处理;窄行免耕对大豆产量、产量构成因子及农艺性状影响显著,NT1、NT2处理的产量显著高于CT,NT1、NT2处理产量较CT处理分别增加27.8%和22.1%;窄行免耕对大豆蛋白质含量、脂肪含量、脂蛋总和影响不显著。但对脂肪总量、蛋白总量以及脂蛋总量影响显著。NT1处理的脂肪总量、蛋白总量,显著高于NT2处理,NT2处理显著高于CT处理;而NT1和NT2处理之间的脂蛋总量差异不显著,但是显著高于CT处理。

Abstract: To study the effect of narrow-row no-till on soybean root, grain yield and quality, three treatments were set including 30 cm narrow-row no-till (NT1), 19 cm narrow-row no-till (NT2) and 68 cm traditional tillage (CT). The results indicated that dry and fresh root weight per plant of NT1 and NT2 were significantly lower than that of CT. However, the dry and fresh root weight of group of NT1 and NT2 were significantly higher than that of CT. Narrow-row no-till had significant effects on soybean yield, yield component and agronomic traits, and the grain yield of NT1 and NT2 was 27.8% and 22.1% higher than that of CT, respectively. There was no significant difference in grain protein content, fat content, and total protein-fat proportion among the three treatments. However, significant difference was found in total fat content, total protein content and total protein- fat content. Total fat content and total protein content of NT1 were significantly higher than that NT2, which were significantly higher than that of CT. The total protein- fat content had no significant difference between NT1 and NT2, but it was significantly higher than that of CT.
