摘要:为了充分利用油桐幼林空间,扩大种植效益,对油桐-花生、油桐-芝麻和纯林3种套种模式林分套种前后的土壤物理化学性质、林分生长量和套种经济效益进行比较研究。结果表明:油桐幼林地套种花生能够显著降低土壤容重、增加土壤孔度和含水量和土壤碱解N、速效K、有机质、全K含量,促进油桐幼林生长,同时可以充分利用林分空间,填补了油桐林结果前的经济效益空白,是3种套种模式中最佳套种模式。
To make full use of the space and expand the benefit of young tung-oil trees, soil physical and chemical properties before and after intercropping and intercropping economic benefits of tung-peanut, tung-sesame and pure forest three intercropping mode were comparatively studied in the experiment. The results showed that: young tung-oil trees intercropping peanut could significantly reduce soil bulk density, increase hole degrees and moisture, enhance soil alkali-hydro N, available K, organic matter, total K capacity, and promote growth of young tung-oil trees. And tung-peanut intercropping could make full use of the forest space and fill the benefit blank before yield, so it is the modest through the three intercropping modes.
