板栗是我国传统的优势树种,是出口创汇的拳头产品。蚕茧是国际市场的抢手货。板栗生长缓慢,进入丰产期晚,一般栽后15年才能进入丰产期;栽植大叶桑可实现当年养蚕,实现快速效益;白花草木樨是一种优质绿肥,具有发芽早,易腐烂的优点。因此,板栗、大叶桑、白花草木樨间作是建立双出口基地,长期效益与近期效益相结合,以草治虫、以草养地、用草为肥的最佳立体栽培模式,是一个集生态、经济与社会效益于一体的栽培模式。1、搞好规划设计:根据土壤肥沃情况、地形地貌以及当地的气象环境,确定主栽树种与配套树种的栽植密度。土壤肥沃地势平坦的适当稀些;反之则密些。板栗栽植密度有:3×4米、3× Chinese chestnut chestnut is the traditional advantages of species, is the leading export products. Cocoon is a hot commodity in the international market. Chestnut slow growth, late into the high yield late, generally 15 years after planting can enter the high yield; planting mulberry leaves can be achieved that year, sericulture, to achieve rapid benefits; white mulberry is a high-quality green manure, with germination early, perishable advantages . Therefore, the chestnut, big leaf mulberry, white flowers and grass mulberry intercropping is to establish a dual export base, the long-term benefits and the recent benefits, the grass worm, to grassland, grass for the best three-dimensional cultivation mode, is a collection of ecological , Economic and social benefits in one of the cultivation mode. 1, do a good job planning and design: According to fertile soil conditions, topography and local meteorological environment, to determine the main planting species and supporting planting density. Appropriately flattened soil fertile rare thin; the other is more dense. Chestnut planting density: 3 × 4 meters, 3 ×
