对人工接种弗兰克氏菌的木麻黄幼林进行施肥效应的研究结果表明 :施肥能显著地提高木麻黄幼林的生长 ,施肥处理的树高和胸径分别比不施肥的增加 0 .8%～ 57.1%和 10 .1%～ 55.3% ;年均材积平均每公顷增长 0 .880 14～ 2 .8170 4 m3 。最佳施肥处理 (配方 )是 N10 0 P2 50 K3 7.5。在人工接种弗兰克氏菌的木麻黄幼林三要素施肥中 ,第 1、2年以 P肥为主要影响因素 ,第 3、4年以 N肥为主要影响因素。施肥的时效性在第 2年为最大肥效时间 ,随着林龄的增加肥效下降。不同施肥处理的叶片 N含量也有明显的不同 The results of fertilization on Casuarina equisetifolia inoculated with Franklinomyces showed that fertilization could significantly increase the growth of Casuarina equisetifolia, and the tree height and DBH of fertilization treatments increased by 0.8% -57.1% and 10.1% ~ 55.3%; average annual volume increased by 0.880 14 ~ 2.8170 4 m3 per hectare. The best fertilization treatment (recipe) is N10 0 P2 50 K3 7.5. In the artificial inoculation of Casuarina equisetifolia Yulin three elements of fertilization, the first and second years to P fertilizer as the main influencing factors, the first 3, 4 years to N fertilizer as the main influencing factors. Timeliness of fertilization in the first two years as the maximum fertilizer time, with the increase of age, fertilizer efficiency decreased. Different fertilization leaf N content is also significantly different
