| 摘 要： | 为了明确冬种稻草覆盖免耕马铃薯的最佳播种期,于2011年在广西宾阳县进行不同播种期对稻草覆盖免耕马铃薯产量及其生长特性影响的试验研究。结果表明,第1、2播种期的出苗速度较快,出苗率较高;随着播种期的推迟,出苗速度减慢,出苗率降低。马铃薯的总产量、单薯重大于100 g产量、总产值,以第1、2播种期较高。随着播种期的推迟,呈下降趋势。由此可见,广西宾阳县冬种稻草覆盖免耕马铃薯的最佳播种期应在11月中上旬。

| Abstract: | In order to identify the best sowing time of straw-mulching no-tillage winter potato, a field experiment was carried out in Binyang, Guangxi in 2011 to test the influence of different sowing times on the yield and the production characteristics of the potato. The results indicate that the emergence speed and the emergence rate were higher in the 1st and 2nd sowing times, and decayed with the delay of sowing time. And the total yield, the yield of potatoes which single-weight is higher than 100g, and the total output value for the 1st and 2nd sowing times are also higher and declined along with sowing time. As a conclusion, the best sowing time for straw-mulching no-tillage winter potato in Binyang is early November. |
