Abstract:

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.
