| 摘 要： | 不同打顶时间与方法对甜荞产量及其性状的影响研究结果表明:甜荞盛花期(田间有60%的植株开花时)打顶能显著提高单产和结实率;以盛花期主茎、侧枝顶端均打顶产量最高。其原因主要是打顶可明显降低株高、增加各级分枝数、减少单株花数、增加单株粒数、提高单株结实率、提高单株产量,从而提高单产。

| Abstract: | Based on the studies of the influence of different topping time and methods to common buckwheat on yield and constitute factors,the results showed that:the flowering of common buckwheat topping which had 60% flowering can significantly increase the per unit yield and seed number.The flowering of per unit area yield of topping stem and side branch were the highest.The main reason was the topping can significantly reduce the plant height,increase branch number,reduce number of flower,increase seed number,increase spikelet fertility,increase yield per plant,thereby increase the yield per unit area. |
