随着脐橙产业在江西南部的发展,大量低山丘陵地区被开发成为脐橙经济林地。由于缺乏相应的水土保持设施和有效的治理措施,地力下降、水土流失严重等生态问题凸显。本研究提出在脐橙经济林中套种百喜草,通过2a的套种,测定套种百喜草模式下脐橙经济林的土壤理化性质、肥力,分析脐橙树体生长量以及对汛期和旱期水土流失数据的测定与分析,旨在研究这一套种模式的有效性。结果表明,套种百喜草对坡地脐橙经济林的水土保持及肥力保持具有明显效果,且不会影响树体的生长,是丘陵山地脐橙经济林水土保持的有效方法之一。
With the development of navel orange industry in southern Jiangxi Province, a large number of hilly areas have been developed into navel orange forest. Due to the lack of corresponding soil and water conservation facilities and effective governance measures, the ecological problems such as the decline of soil fertility and soil erosion are prominent. In this study, we proposed that the hippophae rhamnoides intercropped with hippophae rhamnoides, and the soil physical and chemical properties and fertility of navel orange plantations were measured by interplanting 2a. The growth of navel orange trees and the data of soil and water loss in flood season and dry season were analyzed. And analysis, to study the effectiveness of this set of patterns. The results showed that intercalated hippophae rhamnoides had obvious effect on soil and water conservation and fertility maintenance of slopeland navel orange economic forest, and would not affect the growth of tree body. It is one of the effective methods for soil and water conservation of economic forest in mountainous hillside navel orange plantation.
