立体林业是指构成森林资源的各生物群落,依其各自对环境的生态适应性,占据同一立地空间的不同层次所构成的相互依存的立体物质体系。立体林业经营其目的是为了更好地发挥森林的生态、社会,经济多种效益,达到以林促副,以短养长。南京市老山林场科研所遵循生态学和生态经济学原理,选择了早期速生的湿地松林分和营养丰富;经济效益高的平菇,采取相应的技术措施进行林菇间作,现已取得了良好的结果。这为提高土地利用率发展山区经济创造出了一条新路。 一、基本情况 栽培地位于丘陵上部,土壤为粘盘上位黄岗土,树种为6年生湿地松,株行距3×2.5米,树高3.2米,胸径6.1厘米。 二、材料与方法 (一)整地作畦 在郁闭度为0.8的8年生湿地松林行间作畦,畦宽1米、长10米、深20厘米,栽培地四周开好排水沟。 (二)菌料制作 每畦10平方米,用棉籽壳200公斤、磷肥0.4公斤、石灰4公斤、石膏粉6公斤、多菌灵0.4公斤、水250公斤、搅拌均匀,以用手握紧有水珠而不滴为宜,拌后堆积 Stereoscopic forestry refers to the interdependent three-dimensional material system that forms the biological communities that make up forest resources and which occupy different levels of the same site space according to their respective ecological adaptability to the environment. The purpose of the three-dimensional forestry management is to give full play to the diverse ecological, social and economic benefits of the forest so as to promote forestry and fisheries and short-term support. Following the principles of ecology and ecological economics, Laoshan Forestry Station Scientific Research Institute of Nanjing chose the early rapid-growing Pinus elliottii plantation and its nutrient-richness. The mushroom with high economic benefits was adopted and the corresponding technical measures were taken to achieve intercropping. the result of. This has created a new road for the development of mountain economy to improve land utilization rate. First, the basic situation Cultivated land is located in the upper part of the hills, the soil is sticky dish upper Huanggang soil, tree species 6-year-old slash pine, spacing of 3 × 2.5 m, tree height 3.2 m, diameter 6.1 cm. II. Materials and Methods (I) Soil preparation For the 8-year-old wetland pine forest with a canopy density of 0.8, the width is 1m, the length is 10m and the depth is 20cm. (B) the production of bacteria per 畦 10 square meters, with 200 kg of cottonseed hulls, 0.4 kg of phosphate fertilizer, lime 4 kg, gypsum powder 6 kg, carbendazim 0.4 kg, 250 kg of water, stir, to hand tight Drops without dropping appropriate, after mixing accumulation
