摘要：The yield of Chinese chestnut relies on multiple factors including soil, fertilizer, irrigation, and pest management. Hence, it is necessary to develop a simple and cost-effective strategy that can simultaneously modulate the above factors. Mulch films can largely influence the aforementioned factors. In this work, a grinding machine was used to fragment branches, chestnut shell, and involucres into 3-10 cm pieces, and the resulting lignocellulose mulch was applied to cover the soil surrounding Chinese chestnut trees. A field trial found that lignocellulose mulch ameliorated soil properties by increasing soil moisture and soil carbon. Moreover, lignocellulose mulch suppressed weed growth and inhibited chestnut blight, and eventually improved the quality and yield of chestnuts. Cost-benefit analysis showed that the mulch increased profit by 42% in three years compared with the control group. It is concluded that lignocellulose mulch is a viable alternative to plastic mulch, especially for perennial woody plants such as chestnut trees. This work provides an alternative strategy for the management of chestnut and other perennial trees.
