摘  要：
笋用竹深受各族群众的喜爱,但传统母竹挖篼方式繁殖在生产上受到一定的限制。对勃氏甜竹、缅龙竹和野龙竹3种竹子的1 a生、2 a生、3 a生、4 a生竹节灌注生根粉进行埋秆育苗试验。结果表明,灌注生根粉对野龙竹的效果最明显,萌节比均值可达49.20%;其次是缅龙竹,萌节比均值可达43.21%;勃氏甜竹相对最不敏感,萌节比均值仅为38.47%;灌注生根粉对2 a生和3 a生的竹节效果最显著,萌节比均值可达55.96%~58.44%,1 a生和4 a生的萌节比均值为25.27%~34.83%,由此得出,缅龙竹和野龙竹的埋秆育苗可采用灌注生根粉的方法进行。

摘  要：
Shoot-producing bamboos are deeply loved by masses of every nationality. However,the production is limited by the traditional method of propagation with planted root ball. This paper,by the test of seedling with planted culm of 3 species of bamboos: Dendrocalamus brandisii,Dendrocalamus birmanicus,Dendrocalamus semiscandensi,perfusing rooting powder into bamboo knots of one-year-old,twoyear-old,three-year-old,and four-year-old bamboos. Results shows that the effect of rooting powder perfusion on Dendrocalamus semiscandens is the most obvious,average germination is up to 49. 20%; less obvious is Dendrocalamus birmanicus,average germination is up to 43. 21%; and comparatively the most insensitive is Dendrocalamus brandisii,average germination is only 38. 47%; the effect on bamboo knots of two-year-old and three-year-old bamboos is the most obvious, average germination 55. 96% ~58. 44%; while average germination of one-year-old and four-year-old bamboos 25. 27% ~ 34. 83%. It can be concluded that the method of rooting powder perfusion can be adopted for seedling planted with culm of Dendrocalamus birmanicus and Dendrocalamus semiscandens.
