Preliminary Study on Early Shooting and High Yield Cultivation Technology of Pleioblastus amarus

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.
