| 摘要: |
| 为了研究紫胶虫的寄主植物久树抚育对紫胶产量的影响,通过对云南元江和红河干热河谷区中的久树分别进行截干和修枝整形处理,调查有效枝条的萌发能力和紫胶产量。结果表明,截干高度及截干处的平均直径对有效枝条的总长度和数量无显著影响,但截干位置的分支数量与有效枝条的总长度和数量显著正相关。保留12支左右枝条的中度模式的修枝整形较轻度和重度模式中有效枝条的长度、直径和表面积更加有利于紫胶生产;截干的高度和截干处平均直径对紫胶产量无显著影响,但截干位置的分支数量、萌发的有效枝条总长、数量和着胶枝长与紫胶产量显著正相关,中度模式的修枝整形亩产和单数紫胶产量最高。截干和修枝整形能够影响紫胶的产量,对寄主植物合理的抚育有助于提高紫胶产量。 |

| Abstract: |
| In order to explore the effect of tending of host plant on lac yield,Schleichera oleosain arid-hot valley of Yuanjiang County was dealt with stem cutting,and Schleichera oleosain Honghe County was dealt with pruning.Germination ability of branches and lac yield were investigated.The results were as follows:the height and average diameter in the cutting position had no significant correlation with total length and number of branches,but the number of branches in the cutting position had significantly positive correlation with total length and number of branches.And in three mode of pruning,the length,diameter and surface area of branches in moderate mode,which kept branches about 12,were more favorable for improving lac yield.The height and average diameter in the cutting position had no significant correlation with lac yield,but the number of branches in the cutting position,the total length and number of branches and the length of branches holding lac insect had significantly positive correlation with lac yield.And the yield in pruning of moderate mode and the yield per plant were the highest.Stem cutting and pruning could influence lac yield,and reasonable tending can help to improve lac yield. |
