摘要: 对马尾松(Pinus massoniana lamb)无性系种子园10a生始花期嫁接母树和20a生盛果实生母树雌雄花枝和营养枝的N、P、K等营养元素及碳水化合物的动态进行了研究。分析表明:①嫁接母树各类枝条的N、P、K总量基本一致,碳水化合物总量差异显著;②实生母树与此相反,N、P、K总量差异显著(雌雄花枝的全P含量分别为营养枝的32.46倍和46.11倍;营养枝K的含量分别为雌雄花枝的1.81倍和1.68倍),而碳水化合物总量基本一致;③嫁接母树雌雄花枝碳水化合物总量分别为实生母树的2.06倍和1.61倍,而营养枝碳水化合物总量基本一致;④根据两类母树碳、氮比值,初步认为马尾松的雌雄花枝C/N以8.5~9.0较有利于花芽分化。本研究对马尾松种子园水肥管理和增产措施有一定参考价值。

Abstract: This research deals with the vegetative dynamitic analysis of the flowering and vegetative branches of massoniana's clonal seed orchard's 10 years female grafted seedling in early flowering and 20 years mature mother seedling.Analysis parameter includes N,P,K,carbohydrate etc..Results are:(1) The total N,P and K of female grafted seedlinga's branches are almost the same,but the carbohydrate contents are obviously different;(2) Mother seedling is opposed to female grafted seedling.The total N,P and K are obviously different (The total P of male and female flowering branches is respectively 32.46 and 46.11 times of vegetative branches';the total K of vegetative branches is respectively 1.81 and 1.68 times of male and female flowering branches') and the carbohydrate contents are almost the same;(3) The carbohydrate contents of grafted seedling of male and female flowering branches are respectively 2.06 and 1.61 times of mother seedling's and the carbohydrate contents of vegetative branches are almost the same;(4) According to the ratio of C to N in two kinds of female trees,C/N in 8.5~9.0 is advantageous to flower bud differentiation.The research was beneficial to water and fertilizer management and increasing production measure for massoniana's seed orchard.
