| 摘 要： | 根据在鄂西大老岭林场进行的日本落叶松中龄林4种施肥量、3种N与P配比、2种施肥次数的3a试验效应研究,结果表明:不同施肥量、不同N、P比、不同施肥次数对日本落叶松中龄林生长影响不显著;但14a生B1材积生长比其它平均材积提高28.4%。施肥组合8(A1B1C1)各年生长量均高于其它组合的生长量,其材积比其它平均材积提高32.8%。 |

| Abstract: | According to the study on 3 years test effects ,fertilization applied over 4 kinds of measurement, 3 kinds of N and P composition and 2 kinds of fertilization times for fertilization of medium-aged forest of Larix kaempferi in Dalaoling Forest Farm of Hubei were carried out . The results show that different fertilized quantity, different N and P composition and different fertilized times are not significant in effect of medium-aged forest growth of Larix kaempferi, however, the 14 years old with B1 volume growth is improved 28.4% than other average volume. The growth of fertilization composition 8 (A1B1C1) in each year is higher than the growth of other ones, and its volume is improved 32.8% than other average volume. |
