不同播期对习水县大豆品种产量及品质的影响
Effects of Different Sowing Dates on Yield and Quality of Soybean Varieties in Xishui County
摘要
Abstract
In order to explore stubble succession and composite planting while identifying suitable soybean varieties for optimal planting periods in Xishui County,a split-plot design with randomized block arrangement was implemented.Seven soybean varieties were cultivated across five sowing dates to investigate the effects of sowing dates on agronomic traits,yield,protein content,and fat content.The results demonstrated significant impacts of sowing dates on soybean agronomic traits,yield,and quality.With delayed sowing,the number of effective pods,total pods,total seeds per plant,seed weight per plant,and 100-seed weight initially increased and then decreased,while seeds per pod gradually declined.The yield of Youchun 1204 and Qihuang 34 varieties progressively decreased with delayed sowing,whereas other varieties exhibited an initial increase followed by a decline in yield.Protein content showed an increasing trend,while fat content decreased.However,the total protein-fat content displayed no clear pattern.Youchun 1204 achieved the highest yield(5 227.5 kg·ha-1)under the S1 sowing date(April 22),exhibiting superior quality,disease resistance,and lodging resistance.Thus,it is recommended as the primary cultivar for promotion in Xishui County.The optimal soybean sowing window for this region extends from late April to early May.关键词
