摘要
为探究DA-6对大豆生长发育的影响,文章以大豆品种中豆63和皖豆28为试验材料,研究叶面喷施DA-6对大豆主要农艺性状、产量及品质的影响.结果表明,叶面喷施DA-6后,大豆株高降低、主茎节数增加,单株有效荚数、单株粒数、单株粒重和大豆产量显著提高,对有效分枝数影响不明显.大豆产量品质与主要农艺性状相关性分析表明,大豆产量与单株粒数和单株粒重呈极显著正相关;蛋白质含量与株高和百粒重呈极显著正相关;脂肪含量与有效分枝数呈极显著正相关;脂肪含量与蛋白质含量呈显著负相关.综合分析表明,叶面喷施DA-6可增加大豆单株有效荚数、单株粒数和单株粒重,提高大豆产量.
Abstract
In order to investigate the effects of DA-6 on soybean growth and development,this article used soybean varieties Zhongdou 63 and Wandou 28 as experimental materials to study the effects of foliar spraying of DA-6 on soybean main agronomic traits,yield,and quality.The results showed that foliar spraying of DA-6 reduced soybean plant height,increased the number of main stem nodes,significantly increased the number of effective pods per plant,number of grains per plant,grain weight per plant,and soybean yield,but had no significant effect on the number of effective branches.The correlation analysis between soybean yield,quality,and main agronomic traits showed that soybean yield was significantly positively correlated with the number of grains per plant and the weight of grains per plant.The protein content was significantly positively correlated with plant height and hundred grain weight;There was a highly significant positive correlation between fat content and effective branching number.In addition,there was a significant negative correlation between fat content and protein content.In summary,foliar spraying of DA-6 increased soybean yield by increasing the number of effective pods,grains,and grain weight per plant.
