丘陵坡地油茶林下新型生态种养模式研究与实践

充分利用茶林间隙土地实施种养立体开发,对丘陵坡地水土保持以及促进农民增收、创收具有重要意义。以湖南应用技术学院农林科技学院丘陵坡地的千亩油茶林为试验基地,通过油茶林下利用牛粪、羊粪养殖蚯蚓和土鸡,探索与实践了一种“茶—蚓—禽”种养结合新型生态模式,对丘陵坡地油茶林下间隙养殖蚯蚓的技术参数和实际效果进行介绍,旨在利用丘陵坡地资源发展林下经济,提高立体综合利用效率,对解决当前丘陵坡地油茶种植普遍存在的前期投入大、产出低、树间土地利用少等现实问题,以及发展丘陵坡地区域经济具有重要的现实意义。

Research and Practice of New Ecological Integrated Planting and Breeding Mode under Camellia oleifera Forest on Hilly Slope Land

It is of great significance for soil and water conservation on hilly slope land and for increasing peasants′ income to make full use of the interstitial land of Camellia oleifera forest to implement three-dimensional development of integrated planting and breeding. Using the 1 000 acres of Camellia oleifera forest on the hilly slope land of Hunan Applied Technology University as experimental base, a new ecological mode of integrated planting and breeding of ′Camellia oleifera-earthworm-poultry′ was explored and practiced. In the Camellia oleifera forest, the earthworms were bred using fermented manure produced by cattle and sheep, and the local chickens were reared using earthworms as feed resource. The technical parameters and actual effect of raising earthworms on interstitial land of Camellia oleifera forest on hilly slope land were introduced. Aiming to use hilly slope land resources to develop under-forest economy and to improve the resources utilization efficiency, this new ecological integrated planting and breeding mode may be helpful for solving the problems in Camellia oleifera planting on hilly slope land, such as high prophase input, low output and inefficiency of interstitial land use in forest. In addition, it is of great practical significance for the development of regional economy on hilly slope land.
