| 摘 要： | 采用二因素裂区试验设计,研究了不同播期和密度对长农35号谷子产量、生育期和植株性状的影响。结果表明:播期对谷子生育期影响较大,播期相同时密度对全生育期几乎没有影响;播期与密度互作对谷子产量和植株性状有较大影响。本研究条件下,长农35号最佳播期和密度组合为5月15日播种、留苗密度45.0万株/hm2,该组合产量最高。根据试验结果和多年栽培经验,认为长农35号的最适播期为5月5～20日,最佳留苗密度为45.0万株/hm2。

| Abstract: | The effects of sowing time and plant density on the yield,growth period and plant characters and of millet variety Changnong No.35 were studied using the two-factor split-plot design.The results showed that the effect of sowing time on the growth period was great.The plant density had no influence on the growth period with same sowing time.The interaction between sowing date and plant density had great influence on the yield and plant characters.The yield was the highest with the optimum sowing time of May 15,and plant density of 450 000 plants/hm2. |
