摘要
总结了在富宁县两个试验点开展的非洲狗尾草快速繁育技术研究,结果表明,快速繁育技术使非洲狗尾草提前生长2~3个月,提前完成生育期15d,有效避免了非洲狗尾草前期幼苗生长缓慢而竞争力弱的问题,促进了种植当年非洲狗尾草的自然繁殖更新;非洲狗尾草快速繁育技术的应用,在坡度较大、翻耕困难、杂草较多的地块进行草地改良取得了显著的成效。
This paper summarized the research on Setaria sphacelata rapid breeding technology carried out at two experimental sites in Funing county.The results showed that the rapid breeding technology made Setaria sphacelata grow 2~3 months in advance and completed the growth period 15d in advance,effectively avoided the problem of slow growth and weak competitiveness of the seedlings in the early stage of Setaria sphacelata,and promoted the natural reproduction and regeneration of Setaria sphacelata in the planting year.The application of Setaria sphacelata rapid breeding technology has made remarkable achievements in grassland improvement in plots with high slope,difficult tillage and more weeds.
