摘要

为了促进金沙江干热河谷区草业开发、畜牧业基地建设和生态农业发展，筛选出再生性强、产量水平高、水分利用效率高的人工牧草，我们于2005年研究了4个不同牧草的再生草产量、再生草生长速度以及再生草水分利用效率。结果表明，所有引进种二茬草的再生速度都比当地轮生狗尾草高。所有引进种再生草的产量都高于当地轮生狗尾草。斯伦春大翼豆、德梅纳罗克非洲狗尾草、贝斯莉斯克伏生臂形草等牧草再生草产量高，水分利用效率高，再生性强，是适于在金沙江干热河谷地区推广种植的节水型牧草。

Abstract

In order to promote the development of grassland

stack base and local ecological agriculture

we carried out experiment of selecting grasses with strong regeneration

high production and high WUE(water using efficiency).We studied the production

the rate of growth and the efficiency of water usage of regenerating grasses of 4 types in 2005.It shows that the second generation grasses of introduced types have higher production than the local grass

hooked Bristlegrass.Three types of introduced grasses

Macroptilium atropurpureum Siratro

Setaria sphacelata Narok

Brachiaria decumbens Basilisk are high throughput

more WUE

and stronger ability of regenerating

they thus are the grasses suitably planted in the hot-dry area of Jinsha River watershed.
