| 摘 要： | 在田间按正交设计方案，进行木麻黄苗期氮、磷、钾施肥试验，并安排了木麻黄苗木五种不同密度试验，结果表明：合理配施氮、磷、钾肥能提高苗木生长量，最佳施肥组合为氮３００ｋｇ／ｈｍ２、磷９００ｋｇ／ｈｍ２、钾１５０ｋｇ／ｈｍ２；适当增大苗木株行距有利于苗高、地径的生长；在一定密度限度（１５００００株／ｈｍ２）下，苗木生物量随密度提高而增加。

| Abstract: | The results indicate that the rational application of N,P and K can increase seedling growth incre- ment and the optimal fertilization combination is 300 kg of N per hm2,900kg of P per hm2 and 150kg of K perhm2;properly increasing the inter-plant and inter-row spacing of seedlings is advantageous to the seedlinggrowth of height and ground diameter; and the seedling biomass increases with the increase of density withinthe limits of 150000 trees per hm2. |
