不同复混肥对湿地松中龄林的施肥效应研究
|
摘要
为了研究不同复混肥对湿地松中龄林的施肥效应,以8年生湿地松林为研究对象,分别以施用2种普通复混肥和自制松树专用复混肥为施肥处理,各处理的施肥量均为700 g·株~(-1);同时以不施肥为对照,进行施肥对比试验。结果表明:3种不同施肥处理中,以自制松树专用复混肥对湿地松林分生长的促进作用最大;施肥3年后林分的平均胸径、树高、单株材积分别较对照增长3.1%、4.7%、10.0%;施肥3年后自制松树专用复混肥处理的平均胸径、单株材积与2种普通复混肥处理间均存在极显著差异,树高均有显著差异;施用有长效作用并具针对性的松树专用复混肥能获得较高的木材增产效益。
In order to study the effects of different compound fertilizer on middle-aged Pinus elliottii forest, with the 8-year-old Pinus elliottii plantation as the research object,by applying two kinds of ordinary compound fertilizer and the self-made pine special fertilizer as the fertilizing treatment,the rates of fertilizer application each treatment were all 700 gper plant,and the CK(no fertilizer application) was used as the control at the same time,carried on the comparative experiment of fertilization.The results showed that the fertilizing treatment by the self-made pine specific fertilizer was most efficient for trees growing in the three treatment, the average DBH, height and individual volume increased by 3.1%,4.7% and 10.0%respectively compared with CK at three years after fertilization.After three years fertilization, the average DBH and individual volume of the trees stand applying self-made pine special fertilizer were extremely significantly difference from those of the two kinds of ordinary compound fertilizer treatments, and the height was significantly difference.And fertilization by pine specific fertilizerwith controlled-release and pertinency in middle-aged P. Elliottii forest plantation could increase the yield and wood benefit of per unit area.
