Method for cultivating polygonatum cyrtonema under phyllostachys edulis forest

Abstract

The invention relates to a method for cultivating polygonatum cyrtonema under a phyllostachys edulis forest. The method comprises the following steps that 1) the phyllostachys edulis forest which is loose and fertile in soil and few in miscellaneous shrubs, is close to a water resource and is managed as a material forest is selected; the phyllostachys edulis forest downhill is selected; 2) when the polygonatum cyrtonema is cultivated in the phyllostachys edulis forest for the first time, the first cultivation density is 24000-36000 plants / hm<2>; appropriate after-cultivation is conducted on sparse parts by combining underground tubers in a digging process or seedlings; and 3) a sprout and leaf growth fertilizer of phyllostachys edulis is broadcast; an annual one-time fertilization measure taken in management of the phyllostachys edulis forest is combined; a compound fertilizer or an amino acid fertilizer is broadcast in after-rain forest land in a sprout and leaf growth period of the new phyllostachys edulis from April to May; the annual fertilization amount is 300-450kg / hm<2>; a harvest time fertilizer of the polygonatum cyrtonema is broadcast; in a digging process of underground tubers of the polygonatum cyrtonema, the compound fertilizer or the amino acid fertilizer is broadcast in hole digging parts; soil is covered and compacted after the fertilizer is broadcast; and the annual fertilization amount is 900-1200 kg / hm<2> for the compound fertilizer or 1800-2700kg / hm<2> for the amino acid fertilizer. An output value of the tubers can be great; after the fertilizer cost, the labor cost and the like which are increased in the compound management are deducted, a profit increased annually is great; and economic benefits are very remarkable.

Description

technical field [0001] The invention relates to a method for cultivating Polygonatum multiflora, in particular to a method for cultivating Polygonatum multiflora under a moso bamboo forest. Background technique [0002] bamboo( Phyllostachys edulis (Carr.) H. de Lehaie) is a well-known economic bamboo species in China, and has a large contribution rate to regional rural social economy. However, it is difficult for scattered bamboos such as moso bamboo to flower and set fruit. At present, genetic breeding is more difficult, and the improvement of yield mainly depends on the regulation of stand structure and soil management. Through the implementation of intensive management measures, the productivity of moso bamboo forests can be brought into full play, but if only bamboo and bamboo shoots are the production targets, it will be more and more difficult to improve the economic output and benefits of moso bamboo forests. In view of the fact that the utilization rate of moso ba...
