摘　　要：为了准确掌握长沙屋顶菜园种植豇豆的最佳播种期,从2014年3月上旬开始到9月上旬,每月的5、15、25日在屋顶菜园播种1批,共播种19批豇豆,测量每批豇豆的产量,并从气温变化角度分析豇豆的最佳播种期。结果表明,屋顶种植豇豆最早播种时间为3月中旬,最迟播种时间是8月中旬;在3月中旬前和8月中旬后播种的豇豆,产量显著下降;从经济效益方面分析,6月中旬到8月中旬播种,豇豆的经济效益显著高于其他批次。In order to grasp accurately the best sowing time of planting cowpea in the roof garden in Changsha, from early March to early September, one batch of cowpeas was sowed on 5, 15, 25 of every month in the roof garden, and there were 19 batches in total. The yield of each batch was measured and the best sowing time was analyzed from the perspective of temperature. The results showed that the earliest sowing time of cowpeas in the roof garden was mid-March, and the latest sowing time was mid-August. The yield of cowpea decreased significantly before the mid-March and after mid-August. The economic benefit of cowpeas sowed from mid-June to mid-August was significantly higher than that of other batches.
