不同海拔高度对灵山正路椒产量和品质的影响

摘要

In order to fully understand the ecological adaptability ofZanthoxylum bungeanum at different altitudes, taking Z. bungeanum 'Lingshan' selected and identiifed by Mianning County as materials, the effects of different altitudes on phenophase, quality, yield and economic beneift of Z. bungeanum'Lingshan' were investigated and researched under six altitudes from 1 800 m to 2 800 m at Mianning County. The results indicated that the phenophase was delayed with altitude rising. The quality and yield had positive correlations with altitude among 1 800~2 600 m, and were decreased with altitude going on increasing. The maximum of economic beneift was achieved at 1 800 m and 2 000 m.%为了全面了解花椒在不同海拔下的生态适宜性,以四川省冕宁县选育认定的灵山正路椒为材料,在冕宁县1 800、2 000、2 200、2 400、2 600、2 800m 6个海拔梯度条件下,调查研究不同海拔高度对灵山正路椒的物候期、品质、产量、经济效益的影响.结果表明:物候期随海拔的升高而向后延迟;品质、产量在海拔1 800~2 600m范围内与高度呈正相关,之后降低;经济效益在海拔1 800、2 000m时最高.
