兰溪红壤区食用笋的研究
Growth and economic benefit of food bamboos on red earth of Lanxi
【摘要】 在兰溪市低丘红壤实验区,引种了十多个食用笋品种,经多年试验研究,初步明确了在本试区适生的食用笋品种——黄甜竹、红竹、角竹、雷竹,这几个品种用普通的造林抚育管理措施:3~4年即郁闭成林,比当地适生的毛竹(笋竹两用林)提前2~3年郁闭投产;并具有较高的经济效益,以销售母竹计算,平均产投比为8.57∶1;以经营食用笋计算,产投比为8.0∶1;这均高于当地其他种植业.发展食用笋,一旦成林就可永续利用.3年生的食用笋竹林,地表径流系数比无林地减少50.7%,土壤侵蚀模数降为零.经济效益、生态效益和社会效益显著。
【Abstract】 The experiment of introduction of bamboos on red earch of Lanxi proves that there are adaptablebamboos, i. e. Acidosasa edulis. Phyllostachys iridenscens, Ph. fimbriligulatu, Ph. praccox. TheirO/ I(output/ input) ratio is 8.57: 1 ~ 8.0: 1. Comparing with that of control area, the runoffcoefficiency decreased by 50.7% and the module of soil runoff loss is zero in the bamboo ecosystems.These food bamboos have better economic benefit, ecological effect and social benefit.
