沙生灌木平茬效应研究

A Review of Researches on Rejuvenation Effects of Sandy Shrubs

平茬是沙生灌木抚育更新的重要措施之一。该研究综述了平茬技术要点及其平茬对沙生灌木生长状况、林间生境、生理特征和病虫害方面的影响。同时指出,未来需要进一步加强对多控制因素(平茬时间、留茬高度、平茬周期和平茬方式等)结合进行长期深入研究,以确定沙生灌木最佳的平茬方案,从而为荒漠治理和风沙区植被恢复与重建提供切实可行的技术手段和科学依据。

Stubble is one of the important measures for the cultivation and renewal of sandy shrubs.In this study,the main technical points of stubble and its effects on the growth condition,interforest habitat,physiological characteristics of sand-bearing shrubs and diseases and insect pests were reviewed.At the same time,it was pointed out that the combination of multiple control factors(stubble time,stubble height,stubble cycle and stubble pattern)should be further strengthened in order to determine the best stubble plan for desert shrubs,so as to provide practical technical means and scientific basis for desert control and vegetation restoration and reconstruction in sandy areas.
