1984年6月~1986年1月在白沙县细水牧场试验的结果表明,适用于草地改良的热带牧草有12种,其中禾本科牧草有糖蜜草、141狼尾草、旗草、棕籽雀稗、坚尼草、甘巴草,豆科牧草有库克笔花豆、西卡笔花豆、爪哇葛藤、格雷厄姆笔花豆、卵叶山蚂蝗、阿切尔大结豆。

We selected the dichromatic lespedeza first.After the test of cul- tivating it in small area and the test of feeding it to the animals,we got a clear understanding of its botanical feature and biological specific property,its good properties of high output of grass and high nutritive value and its culture technique further.After the plot test,we adopted different techniques of grassland improvement in the light of dif ferent natural grassland types,and then we conducted a pilot project before we spreaded the...

We selected the dichromatic lespedeza first.After the test of cul- tivating it in small area and the test of feeding it to the animals,we got a clear understanding of its botanical feature and biological specific property,its good properties of high output of grass and high nutritive value and its culture technique further.After the plot test,we adopted different techniques of grassland improvement in the light of dif ferent natural grassland types,and then we conducted a pilot project before we spreaded the technique in large area.The success in aeroplane sowing technique speeded up the grassland improvement.We closely combined with the primary grassIand improvement and the secondary feeding and production of the animals,and raised the economic effect,the social effect and the ecological effect. Lespedeza is not only the resources of a good protein stock food,but also“the king of conservation of water and soil”.It can supply raw material for the weave production,and serve as the energy resources of thecountryside and bee plant.It can yet be regarded as one of the chief breed of grassland improvement in the east mountain area iu our province.

选择二色胡枝子,经过小区栽培试验与动物饲养试验,进一步搞清了二色胡枝子的植物学特征与生物学特性,产草量与营养价值高的优良性状与栽培技术。小区试验后根据不同的自然草地类型,采取不同的草地改良技术,进行了中间试验,然后大面积推广。飞播技术的成功加速了草地改良进程。本文紧密结合第一性的草地改良与第二性的动物饲养生产,提高了经济效益、社会效益和生态效益。胡枝子不仅是优良的蛋白质饲料资源,又是“水土保护之王”,还能提供编织工艺原料,充作农村能源和蜜源植物,用途很广泛,不失为我省东部山区改良草地的当家品种之冠。

The objective of this study is to probe into the ecological adaptability, productivity and management techniques of sheep in south Gui-zhou, and also a series of technique methods to the construction of natural and artificial grass land in this region.

本研究探索绵羊对贵州南部生态环境的适应性、生产能力和相应的饲养管理技术;贵州南部天然草地改良和人工草地建植的系列技术措施。结果表明:采用地面全垦,增施肥料和合理的利用方式等综合措施,对提高草地的初级生产能力和控制草地退化有极显著作用。三年引饲绵羊结果,绵羊只数增长2.4倍。采取绵羊草场成地管理方式,成地草场比非成地草场牧草产量高,质量好。
