摘要:
?为选择大豆苗期干旱胁迫条件下适宜的种子处理技术，以南豆12为材料，采用盆栽试验法研究在苗期轻度干旱胁迫（A1）、中度干旱胁迫（A2）和正常供水（A3）3种水分处理下，研究种衣剂包衣（B1）、烯效唑干拌种（B2）、根瘤菌拌种（B3）和种子不处理（B4）4种种子处理方式对大豆农艺性状、产量及品质的影响。结果表明：苗期水分胁迫较正常供水处理大豆的株高降低，第1节间长度缩短，茎粗增加，倒3叶叶面积减小，对产量和品质无显著影响。种子处理较不处理显著提高了大豆的产量和品质，以B2处理的大豆单株籽粒、蛋白质和粗脂肪产量最高，其次为B1。在苗期适度干旱胁迫下烯效唑干拌种显著降低了大豆的株高，缩短第1节间长度，增加茎粗和倒3叶叶面积，提高了大豆产量，改善了大豆品质；在轻度干旱胁迫下，烯效唑干拌种的大豆单株籽粒、蛋白质和粗脂肪产量分别比对照提高34.59%、34.85%和28.70%，在中度干旱胁迫下，则分别提高29.36%、31.93%和24.11%。
Abstract:
?In order to choose out the appropriate seeds treatment under drought stress conditions at soybean seedling stage,a pot cultivation experiment was conducted to explore the influence upon agronomic properties,yields and qualities of soybean(Glycine max(L),cv. Nandou 12)with four seed treatments of seed coating(B1),uniconazole powder for dry seed(B2),seed dressing with rhizobium(B3)and normal seed(B4)under slight drought stress(A1),middle drought stress(A2)and normal irrigation(A3).The results showed that drought stress treatments declined plant height,shortened the first internode length,increased stem diameter and decreased area of the third leaf from top,but had no significant effect on yield and quality,compared to normal water supply at seedling stage.Compared with nonseed treatment,seed treatments could significantly increase yield and quality of soybean,the values in B2 were the highest,followed by B1.Uniconazole powder for dry seed could significantly reduce plant height,shorten the first internode length,increase stem diameter and area of the third leaf from top,in addition,yield and quality were improved as well,under moderate drought stress.Seed,protein and fat yield in B2 were higher than those of B4 by 34.59%,34.85% and 28.70% under slight drought stress,while,under medium drought stress were 29.36%, 31.93% and 24.11%,respectively.
