10 个枸杞品种 并开展栽培对比试验,对各品种

2 龄幼树全年

7 次采摘的干果产量进行了方差和产量累进曲线分析.结果表明, 品种间产量差异显著;

0901、 宁杞

3 号、 宁杞

4 号、 宁杞

7 号、 宁杞

5 号5个品种产量均较对照宁杞

1 号有所增加, 从产量指标上判断,可作为适宜栽培品种.10 个品种夏果累进增速均较秋果快;

秋果产量是影响总产量排名的 主要因素;

适宜栽培品种中,宁杞

3 号秋果产量增速最快,应重视果园秋季管理,以进一步提高产量;

宁杞

5 号秋果产量增速最慢,宁杞

7 号增速较慢,应主抓夏果的生产;

0901、宁杞

4 号、宁杞

1 号全年产量增速较平稳, 应同时重视夏果、秋果的生产. 关键词:枸杞;

10 varieties of L. bararum were introduced from Ningxia and Inner Mongolia, and a cultivation comparative experiment was carried out, the yield variance and progressive yield curve of dried fruit yield of 2-year-old seedlings of

10 varieties were analyzed, which was picked

7 times in the whole year for each variety. The results show that there are remarkable differences between yields of the varieties. Compared with the control variety of Ningqi No.1, the yields of

5 varieties of 0901, Ningqi No.3, Ningqi No.4, Ningqi No.7 and Ningqi No.5 are increased, and them can be used as appropriate cultivated varieties based on the yield index. The progressive increasing speed of summer fruit yield of

10 varieties is faster than that of autumn fruit yield. The yield of autumn fruit is the main factor influencing ranking of total yield. Among the appropriate cultivated varieties, the increasing speed of autumn fruit yield of Ningqi No.3 is the fastest, so the orchard management in autumn should be paid more attention to, in order for further increasing yield. The increasing speed of autumn fruit of Ningqi No.5 is the slowest, and that of Ningqi No.7 is slower, so the production of summer fruit should be paid more attention to for the two varieties. The increasing speed of annual yield of 0901, Ningqi No.4, Ningqi No.1 is more stable, so the production of summer fruit and autumn fruit should be paid attention to, simultaneously.
