摘要
通过对丽秋3号在浙西南山区的不同播种期试验,明确丽秋3号的最佳播种期为7月25日至8月8日,以8月1日播期,产量最高,各种农艺性状表现最好。不同播种期对丽秋3号产量有着显著的影响,在所有播期中丽秋3号产量呈中间高两头低分布。播期8月1日产量最高2523 kg/hm^2,而播期6月27日产量最低,只有1 392 kg/hm^2。文章还分析了播期与各性状的相关性。说明过早播种与过迟播种均会降低产量,在生产上安排合理的播种期是能否高产的关键。
The investigation of different sowing dates on soybean cultivar Liqiu 3 in the mountainous area of southwest Zhejiang indicated that the optimal sowing duration was from July 25 to August 8. Sowing date on August 1 obtained the highest yield with best performance of various agronomic traits. Sowing dates had significant effects on the yield of Liqiu 3, with higher yield in the middle sowing dates but lower yield in both early and late sowing dates. The highest yield of 2 523 kg/ha was obtainedon August 1, while the lowest yield of 1 392 kg/ha was on June 27. Correlations among sowing dates and agronomic traits were analyzed. The results demonstrated that both early and late sowings reduce soybean yield, and the selection of appropriate sowing dates is the key to achieve higher yield.
