泡桐进入农田,与一年生农作物共生,是50年代河南豫东平原劳动人民在长期与风、沙、干旱等自然灾害斗争的生产实践中所找到的一种适合生态环境和经济要求的农林复合经营形式。目前在华北平原地区已推广到9个省(市),约30万公顷。本文在笔者已进行的对农桐间作的生态效益、产量效应和经济效果等研究的基础上,应用技术经济学原理和方法,对黄泛平原旱作风沙区农桐间作进行了技术经济效果的动态分析和评价,旨在全面、客观、科学地评价农桐间作形式,为有关部门制定产业结构的调整政策,改革种植制度提供依据,为平原农区发展农桐间作,合理安排农作物组合和提高经营管理水平提供经验,为其他混农林业项目的评价提供方法。
Paulownia into the farmland, and the symbiotic annual crops, is the work of the working people in the Henan Yudong Plain in the long-term and wind, sand, drought and other natural disasters struggle in the production practice to find a suitable ecological environment and economic requirements of agroforestry form . Currently in the North China Plain has been extended to 9 provinces (cities), about 300,000 hectares. Based on the research on the ecological benefits, yield effects and economic effects of intercropped with Agrotis fortunei, this paper applied the principles and methods of technical economics to conduct technical and economic results Dynamic analysis and evaluation aims to comprehensively, objectively and scientifically evaluate the intercropping patterns of Arborvitae, provide the basis for the relevant departments to formulate the industrial structure adjustment policy and reform the planting system, and to develop Arborvitae Intercrops for the plain farms, and arrange the crop combinations reasonably Management experience to provide experience for other agroforestry projects provide a method for evaluation.
