造林密度对林下经济作物的影响研究——以茶树菇为例

Study on the Influence of Aflorestation Density on Under Growth Cash Crops-A case Study of Edible

在造林密度为1000、1500、2000、2500、3000株/hm2的林下对茶树菇的生长高度和生长胸径进行调查并对比分析,同时对其生长因子进行估值比对。研究结果表明:造林密度为1000株/hm2林下的茶树菇生长高度和生长胸径均处于整体数值的高值段位,且茶树菇环境综合指数、温度指数、土壤湿度、土壤营养要素指标较高,存在一定空间和适宜度。

The cultivation and planting of cash crop under forest is an important part of developing forestry economy.The planting density and economic planting crops under forest have certain influence on each other.In this paper,the growth height and dbh of Agrocybe aegirit under 1000、1500、2000、2500 trees/hm2 and 3000 trees/hm2 were investigated and analyzed,and the growth factors were estimated and compared.Edible fungi is one of the main forms of Cash crop under forest,and there is an interactive relationship between the cultivation of edible fungi under forest and the planting density,which is mainly related to the climatic environment under forest,the suitable degree of cultivation of edible fungi,the growth condition and so on.The results showed that the height and dbh of Agrocybe aegirit under 1000 trees/hm2 forest density were in the high value range of the whole value,and agrocybe Chaxingu environmental comprehensive index,temperature index,soil moisture,soil nutrient index were higher,there were some space and suitable degree.
