Abstract

A cultivation method for interplanting Polygonatum multiflora and annual economic crops in a young forest Torreya base, including the selection of young forest Torreya rhizome bases, quality requirements for Polygonatum multiflora seedlings, matching of annual economic crops, making ridges for site preparation, applying basal fertilizer in strips, planting methods, and post-planting management , Harvesting steps. The beneficial effects of the present invention are: without reducing the comprehensive benefits of "Torreya multiflora Polygonatum" woodland in advance, the organic combination of long, medium and short economic benefits of the young forest Torreya base is truly realized, and annual income is achieved, solving the problem of The problem of "only input, no output" in the cultivation model of "Treya-polyflora Polygonatum" before production; the interplanted annual economic crop provides a good shade environment for the growth of Polygonatum polyflora, and the quality of Polygonatum polyflora is better; The growth of Chinese torreya and the improvement of the quality of Chinese torreya seeds.

Description

technical field [0001] The invention belongs to the technical field of agro-forestry compound management and cultivation, in particular to a cultivation method for interplanting Polygonatum multiflora and annual economic crops in the unclosed young forest Torreya base. Background technique [0002] Torreya grandis Fort.ex Lindl.cv.Merrillii. is a unique tree species in China, mainly growing in Yixian County, Anhui Province and Zhuji, Fuyang, Songyang and other places in Zhejiang Province. The newly built torreya base is generally planted at a density of about 30 plants. Torreya torreya takes 10-15 years from planting to full production. Before the full production, there is only investment but no return. In order to increase the economic income before the peak production period, Zhejiang and other places interplant Polygonatum multiflora in the unclosed Torreya base, in order to achieve the purpose of growing long with short. It will wither in August, and the growth period ...
