观赏植物B9、N29的营养和生殖生长研究

Study on Nourishing and Procreation Growth of Ornamental Plant of B9、N29

对B9、N29高接后生长1年的圃地苗越冬枝量的分析认为,摘心处理的N29枝量与基砧径阶的线性方程可表达为y=31x-31.2,R2=0.9884。表现摘心处理使枝量与径阶体现极显著相关;B9表现为摘心与不摘心处理枝量与基砧径阶均不相关。说明N29较B9在圃地更容易进行树体的造型。N29的接点枝条的有花枝率(未摘心枝条)达到65%,B9为84%;N29腋花芽的成花高于B9,容易形成春展一串花,夏秋一串果的果实观赏特点。说明N29、B9在同等条件下植株均易成花、结果而体现其园林用途。

Anslysis of branch quantity lived through the winter of B9, N29 after bark - insert grafting at frist year indicated that the linear equation of N29 of pinching was y = 31x- 31.2, R^2=0. 9884 （y- branch quantity, x- stem rank of rootstock）, and there was a significant correlation between branch quantity of pinching and stem rank of rootstocks, but branch quantity of B9 was a insignificant between pinching and non- pinching, and it showed that N29 was a easier sculpting plant than B9 in grafting nursery, other way, the results showed that the percent of branch with blooms of N29 was 65, B9 was 84, and a string of bolossoms in spring and a string of fruits in autumn because of the ratio of axillary bolossom bud of N29 was higher than B9, both of B9 and N29 formed bolossom bud easy.
