几种不同基质对三角梅扦插生长的影响

Effect of several substrates on the growth of Bougavillea spectabilis cuttage

采用6种不同基质,对三角梅不同枝条进行扦插,研究其对三角梅扦插生长的影响。结果表明:不同 基质其插穗成活率不同,珍珠岩最好;不同基质对生根数、根长、根粗、插穗苗生长速度等影响很大,珍珠岩 加蛭石较好;根据根系活力、可溶性糖、脯氨酸、叶绿素含量等生理指标,蛭石与珍珠岩较好。综合所有试验 内容,蛭石与珍珠岩对三角梅插穗生长影响最大。

An experiment on Bougavillea spectabilis was done with six different kinds of substractes. So as to search the effect on the growth of Bougavillea spectabilis. The result showed that: Different substrtes have different effect on the survival-rate and other characters. The rooting-rate of the cuttage in pearl is the best, the mircture of vermiculite and pearl is better; The number. The length, the weighth of roots have been test. Those showed that pearl is the best. According to the test of the content of chlorophlll, soluble sugar, protine nitrate reduce activity of the leaves, it showed that vermiculite is the best in those characters. On the whole, pearl and vermiculite have an better effect on the growing of cutting in Bougavillea spectabilis.
