一、前言青海省玛多地区地势高寒,气候条件恶劣,一般引进的牧草难以完成其生育期。当地每年建立人工草场所需要的草籽不得不靠外地引进。同时,目前引进的牧草在这里一般5—8年就完全退化了。因此,减慢了人工草地建立的速度。为了解决这些问题,我们从1978年开始进行了优良牧草选育及延长其利用年限的栽培技术措施的研究。
I. Introduction The Maduo region of Qinghai Province has terrain and alpine climatic conditions, and the introduction of pasture is difficult to complete its growth period. The local annual grass seeds needed to establish artificial grasslands have to be imported from abroad. At the same time, the current introduction of pasture here generally 5-8 years completely degraded. As a result, the artificial turf slowed. In order to solve these problems, we started in 1978 to study the fine forage breeding and cultivation techniques to extend its useful life.
