| 摘 要： | 为了探明施肥对马尾松人工林生长的影响,在桂西北干热河谷地区选择马尾松人工幼林建立固定样地,采用生物有机无机复混肥不同肥施量进行连续5年4个处理(即A 1.0 kg/株、B1.5 kg/株、C2.0 kg/株,以及CK不施肥)的肥效试验。当林分生长至9年生时,其生长量显示如下规律:(1)胸径生长量为C(11.40 cm)>B(11.10 cm)>A(10.87 cm)>CK(10.80 cm);(2)树高生长量为C(9.87 m)>B(9.43 m)>A(9.23 m)>CK(9.20 m);(3)林分蓄积量为C(79.35 m3/hm2)>B(72.45 m3/hm2)>A(68.34 m3/hm2)>CK(67.33 m3/hm2)。从总体上看,马尾松人工幼林生长量显示出施肥比不施肥提高1.5%～17.9%,其中,施肥量2.0 kg/株处理对林木生长的效果显著。 |

| Abstract: | In order to verify the effect of fertilization on growth of the Pinus massoniana planted young forest,set up the fixed sample sites of the Pinus massoniana planted young forest which were located in xerothermic valley area of Northwest Guangxi.The paper introduced the biological organic-inorganic compound fertilizers with the different usage of fertilizer for fertilizer trial for five consecutive years,namely A is 1.0 kilogram per tree,B is 1.5 kilogram per tree and C is 2.0 kilogram per tree and CK(not manured) each of them with the three repeat the test.When forest tree growth came up to nine years old,the increment showed the results:(1) The DBH increment were C(11.40 cm)>B(11.10 cm)>A(10.87 cm)>CK(10.80 cm);(2) The height increment were C(9.87 cm)>B(9.43 cm)>A(9.23 cm)>CK(9.20 cm);(3) The stand timber reserve were C(79.35 cm)>B(72.45 cm)>A(68.34 cm)>CK(67.33 cm).The overall,the increment of the Pinus massoniana planted young forest revealed fertilized than not manured improved 1.5%～17.9%,of which fertilized uniformly of 2.0 kilogram per tree was to grow significantly. |
