【目的】比较广东阳春地区阳春砂4种栽培类型的结果率与产量,为阳春砂良种选育和生产提供参考。【方法】采用田间小区试验,考察在自然授粉和人工授粉2种条件下,4种栽培类型(长果1号、长果2号、圆果1号、圆果2号)的结实率、产量之间的差异。【结果】在自然授粉条件下,4种栽培类型的结实率及产量极低,其中长果2号的结实率及产量最高,与其他3种类型比较差异均有统计学意义(P<0.05或P<0.01);在人工授粉条件下,阳春砂4种栽培类型的结实率及产量均明显提高,其中长果2号的结实率及产量最高,与其他3种类型比较差异均有统计学意义(P<0.05或P<0.01)。【结论】4种类型中长果2号是最佳栽培型,应大力推广种植。
【Objective】 The objective of this study was to compare the yield and yield of four types of spring spring grasses in Yangchun area, Guangdong province, and provide references for the breeding and production of spring grasses. 【Method】 Field experiments were conducted to investigate the seed setting rate and yield of four cultivars (Changguo 1, Changoguo 2, Yuanoguo 1 and Yuanoguo 2) under both natural pollination and artificial pollination. difference between. 【Result】 The results showed that under natural pollination, the seed setting rate and yield of the four cultivars were very low. The seed setting rate and yield of Changoguo No.2 were the highest, which were significantly different from the other three types (P <0.05 or P <0.01). Under the conditions of artificial pollination, the seed setting rate and yield of four cultivars of Yangchun sand were significantly increased. The seed setting rate and yield of Changoguo 2 were the highest, and the difference was statistically significant compared with the other three types (P <0.05 or P <0.01). 【Conclusion】 Four types of Zhongguo No. 2 are the best cultivars and should be vigorously popularized.
