摘要
为了分析山西省油松速生丰产林抚育管理措施及栽培要点,本研究在山西省某油松速生丰产林基地开展试验,随机选择4块样地,分别进行病害测定、健康度评价和林下草本层和灌木层植物种类分析。结果可知,油松速生丰产林病害位置分为根部病害、枝干病害和叶部病害,病害位置比较分散,病害类型较多;四块研究样地均有优质、健康、亚健康和不健康的油松,其健康度呈不规律分布;样地2草本层植物种类最多,样地1的灌木层植物种类最多,样地3的林下草本层和灌木层植物种类最少,油松速生丰产林林下植物种类无规律可循。由此可知,山西省油松速生丰产林抚育管理虽已取得突出的优势,但依然存在不同类型的病害,健康程度有待调整,林下植物种类较少,需结合现状选择合理的抚育管理措施,明确栽培要点,从而实现油松速生丰产林增产增收的目的。
In order to analyze the management measures and cultivation key points of Pinus tabulaeformis fast-growing and high-yielding forest in Shanxi Province,this study carried out an experiment in a fast-growing and high-yielding forest base in Shanxi Province,randomly selected 4 plots,and carried out disease detection,health evaluation and plant species analysis of the herb layer and shrub layer under the forest,respectively.The results showed that the disease locations were divided into root diseases,stem diseases and leaf diseases,and the disease locations were scattered and the disease types were more.There were high quality,healthy,sub-healthy and unhealthy Pinus tabulaeformis in the four study plots,and their health degree was irregular distribution.Plot 2 has the largest number of plant species in the herbaceous layer,plot 1 has the largest number of plant species in the shrub layer,plot 3 has the smallest number of plant species in the understory herbaceous layer and the understory shrub layer.It can be seen that although the rapid growth and high yield forest of Pinus tabulaeformis in West province has achieved outstanding advantages,there are still different types of diseases,the health degree needs to be adjusted,and the species of plants under the forest are few.It is necessary to select reasonable management measures according to the current situation and clarify the cultivation points,so as to achieve the purpose of increasing production and income of the rapid growth and high yield forest of Pinus tabulaeformis.
