叙永县苦竹资源丰富，面积约2 667 hm2，主要分布龙凤、叙永、天池、水尾、两河等5个乡镇，管理粗放，几近荒芜状态，经济效益差。2019年，浙川东西部扶贫协作援川专家，采用废竹屑作为覆盖材料，替代常规的覆盖材料，开展苦竹早出丰产培育技术试验，试验面积0.9 hm2。试验结果表明：通过废竹屑覆盖试验，增温效果明显，出笋期提早77 d，笋期延长到82 d，平均产量约24 t·hm-2，平均效益26万元·hm-2，大大降低了覆盖成本，经济效益极佳。覆盖后的废竹屑可以作为培育林下菌的材料，实现废竹屑的二次利用。通过苦竹早出丰产培育技术试验，总结出一套苦竹早出丰产培育技术，为四川省农民增收及脱贫攻坚提供示范。
Xuyong county is rich in Pleioblastus amarus resources, covering an area of more than 40,000 mu. Pleioblastus amarus forests are mainly distributed in Longfeng, Xuyong, Tianchi, Shuiwei, and Lianghe town, their management is extensive, most of them are in a state of desolation, and the economic benefits are very poor. In order to improve the economic benefits of Pleioblastus amarus forests, poverty alleviation and cooperation experts from Zhejiang and Sichuan province carried out an early-shooting and high-yield cultivation technology experiment in Pleioblastus amarus forests in 2019. The experimental forest with an area of 13.6 Mu was established by replacing conventional covering materials with waste bamboo chips. The results showed that the surface soil temperature was obviously increased by the covering waste bamboo chips. The bamboo shoots appeared 77 days earlier than normal control and the shooting period was extended to 82 days. The yield was 24 t·hm-1 and the benefit was 260 thousand Yuan·hm-2. The covering cost was greatly reduced and the economic benefit was improved. The post-coverage waste bamboo chips can be reused as culture medium material of edible fungi under the forests to realize the secondary utilization. A set of early-shooting and high-yield cultivation technology of Pleioblastus amarus was proposed, this may provide a demonstration for farmers to increase their income and overcome poverty in Sichuan Province.
