农牧交错区生态建设与草业开发研究

根据农牧交错区面临的主要生态问题,选择退耕还草,发展苜蓿草业,对该区生态建设和农业可持续发展具有重要作用。考虑到该区贫困人口占大多数,粮食尚不能完全自给,退耕还草和草业发展面临诸多困难的实际情况,本文提出了以旱作农田增产技术、农田保水保土耕作技术、农牧结构优化调整及苜蓿生产技术为主要内容的技术措施,并提出了该区草业发展的基本对策。

Eco-environmental Construction and The Development of Grass Industry in the Farming-Pastoral Ecotone

Confronting with the main ecological problems in the farming-pastoral ecotone,giving up cultivation and resuming grass,developing clover industry are very important for eco-environmental construction and agricultural sustainable development,but there are many needy people in the farming-pastoral ecotone,food cannot self-support entirely,giving up cultivation and developing grass industry confronted with many handicaps.Based on this condition,this paper puts forward a series techniques,including dry farming techniques,molding moisture and keeping soil techniques,adjusting farming and animal husbandry structure and high yield planting techniques of clover,established the technical system of grass industry propulsion in the farming-pastoral ecotone,and puts forward the fundamental countermeasures for the development of grass industry.
