摘要/Abstract

摘要：

以贝斯莉斯克伏生臂形草为试验材料，研究了盛花期后不同收获时间及套袋收种、拍打收种等收种方式对其种子产量、千粒重和生活力的影响。结果表明，与盛花期后28，33，43和48 d相比，盛花期后38 d收获的种子产量最高，并获得较高的千粒重和种子生活力；与传统刈割、1次拍打、2次拍打和3次拍打收种方式相比，套袋收种收获的种子产量和千粒重最高，分别为202.37 kg/hm²和5.11 g。表明盛花期后38 d和套袋收种是云南进行贝斯莉斯克伏生臂形草种子生产的最佳收种时间和收种方式。

Abstract:

The experiments were conducted to study the effect on seed yield, 1000 seeds weight and seed viability of Brachiaria decumbens ‘basilisk’ under different harvest time including the 38 d after the onset of the blooming period and different harvest methods including tying with traditional cutting, tying bag and manual patting harvest methods. The results showed that highest seed yield, 1000 seeds weight and seed viability were obtained with harvesting 38 d after the onset of the blooming period, compared to the other harvest time treatment which including 28, 33, 43 and 48 d treatments. Compared to the traditional cutting method and manual patting methods, the highest seed yield and 1000 seeds weight were obtained with harvesting by tying bag, which was 202.37 kg/hm² and 5.11 g, separately. It was indicated that 38 d after the onset of the blooming period and tying bag was the best harvest time and harvest method of ‘basilisk’ seed production in Yunnan province, respectively.
