摘要
为了分析栽植方式对薛家庄林场油松人工林土壤及造林效果,在薛家庄林场油松人工林研究样地开展试验研究,依据不同栽植方式分为不同处理,CK(保持样地原始状态)、D1(栽植管理)、D2(栽植管理+水肥管理)、D3(栽培管理+水肥管理+疏伐抚育),分析不同栽植方式对油松人工林土壤以及造林效果的影响。结果证实,四个处理的pH值差异不明显(P>0.05)。D3处理的有机质、速效氮、速效磷和速效钾指标均高于其他处理;D3处理的含水率以及毛管孔隙度高于其他处理,土壤容重低于其他处理;不同栽植方式均能促进油松人工林生长,整体呈D3>D2>D1>CK的趋势;不同栽植方式对油松人工林的单株材积以及林分蓄积均产生显著影响,栽培管理+水肥管理+疏伐抚育措施可增加林木的单株材积和林分蓄积,整体造林效果优势突出。由此可知,栽培管理+水肥管理+疏伐抚育的综合性的栽植管理,促进油松人工林生长,造林效果更突出,可改善林地土壤,保证土壤养分充足,可在薛家庄林场油松人工林栽植管理中推广该方式。
In order to analyze the effects of planting methods on the soil and afforestation of Pinus tamariensis plantation in Xuejiazhuang Forest Farm,an experimental study was carried out on the plantation plots of Pinus tamariensis plantation in Xuejiazhuang Forest Farm.According to different planting methods,the plots were divided into different treatments:CK(maintaining the original state of the plots),D1(planting management),D2(planting management+water and fertilizer management),D3(cultivation management+water and fertilizer management+thinning care).The effects of different planting methods on soil and afforestation effect of Pinus tabulaeformis plantation were analyzed.The results showed that the pH values of the four treatments were not significantly different(P>0.05).The indexes of organic matter,available nitrogen,available phosphorus and available potassium in D3 treatment were higher than those in other treatments.The water content and capillary porosity of D3 treatment were higher than other treatments,and the soil bulk density was lower than other treatments.Different planting methods can promote the growth of pine plantation,and the overall trend is D3>D2>D1>CK.Different planting methods have significant effects on individual tree volume and stand stock.Cultivation management+water and fertilizer management+thinning tending can increase individual tree volume and stand stock,and the overall afforestation effect is prominent.It can be seen that the comprehensive planting management of cultivation management,water and fertilizer management and thinning care can promote the growth of Pinus tabulaeformis plantation with more prominent afforestation effect,improve the soil of forest land and ensure adequate soil nutrients.This method can be extended in the planting management of Pinus tabulaeformis plantation in Xujiazhuang forest farm.
