板栗林下套种竹芋栽培技术及效益分析

Analysis of the Cultivation Technique and Benefit of Interplanting Arrowroot in Chestnut Tree

摘要: 贵州望谟县是板栗传统产区，面积28万亩，获得国家地理标志保护产品和“板栗名县称”号。板栗行间距4 m × 4 m，板栗园改造后前3年林下郁闭度低，行间有一定的地面空间、光照及通风条件，发展板栗林下经济，可以增加板栗园综合收益。竹芋是一种富含淀粉的块茎作物，营养价值高，用途广泛，除能直接作为蔬菜食用外，还能制成适于糖尿病患者食用的食品和主治小便赤痛、肺热咳嗽的药品等，开发潜力大。板栗行间套种竹芋，既可以提高土地利用率，提高种植效益，还能改善板栗园生态环境，降低管理成本。本研究在板栗园下套种竹芋，每亩增加收入5594.5元，取得良好的效益。

Abstract: Guizhou Wangmo County is a traditional chestnut producing area, covering an area of 280,000 mu. It has been granted the protection product of national geographic indication and the title of “Chestnut County”. The spacing between chestnut rows was 4 m × 4 m, the canopy density was low in the first 3 years after the transformation of chestnut garden, and there were certain ground space, light and ventilation conditions between rows. The development of chestnut understory economy could increase the comprehensive income of chestnut garden. Arrowroot is a kind of tuber crop rich in starch. It has high nutritional value and wide uses. In addition to being eaten directly as a vegetable, it can also be made into food suitable for diabetes patients and drugs mainly for red urination pain and lung heat cough. It has great development potential. Interplanting arrowroot between the chestnut rows can not only improve the land utilization rate, improve the planting efficiency, but also improve chestnut garden’s ecological environment and reduce management costs. In this study, arrowroot interplanted under the chestnut garden increased the income by 5594.5 yuan per mu and achieved good benefits.
