| 摘 要： | 在陇东黄土高原沟壑区,引进敞口、绛红、辽红3个山楂品种进行栽培试验。结果表明,3个品种在陇东黄土高原沟壑区能正常生长,造林成活率在90%以上,引种品种以敞口最好,降红次之,辽红较差;在相同立地条件下,不同栽培措施对山楂产量的影响次序是:品种—施氮量—密度;在不同立地类型条件下,不同栽培密度,山楂生长量和成活率有明显差异,立地类型以沟坡为优,梁坡次之,梁峁顶最差,栽培株行距以2 m×4 m为最优。

| Abstract: | Three varieties of Crataegus pinnatifida Bge,Changkou,Jianghong and Liaohong,were introduced to the gullied area in the east of Gansu for cultivation tests.The results showed that the three varieties could be grown in this area,with the survival rate to be over 90% and the best to be Changkou followed by Jianghong and Liaohong.On the same site,different cultivation treatments had different influences on the yield.Variety is the most influential factor,followed by use of Nitrogen and the last one of the density.Under different site conditions,densities resulted in different growth rates and survival rates.The best site for cultivation goes to slope of gullies.Ridge slope comes second and the last goes to top of tableland.2 times 4 meters is the best density for cultivation. |
