Promoted maturity warm cultivation method of white-pulp loquat in double-film greenhouse

Abstract

The invention relates to a promoted maturity warm cultivation method of the white-pulp loquat in a double-film greenhouse. The method includes greenhouse structural modification, film application time and removal time determination, and post-mulching fertilizer and water management. The specific steps include 1, setting a double-film greenhouse structure, namely mounting two longitudinal rods at two outer ends of each of inner and outer arch rods, and fixing inner and outer films to the longitudinal rods through plastic lock channels; 2, breeding loquat plants in the double-film greenhouse, namely planting the loquat plants in the double-film greenhouse according to density of 4m*3-5m; 3, applying the films of the double-film greenhouse in late November to early December; 4, managing moisture in the double-film greenhouse, namely after covering with the films, supplying water for the loquat plants mainly by manpower. The promoted maturity warm cultivation method of the white-pulp loquat in the double-film greenhouse has the advantages that in order to overcome the defects of the traditional single-layer greenhouse, the structure is modified, one inner film is added to obtain double films, warmth retention of the greenhouse is improved, anti-freezing capacity of the greenhouse is improved, and the white-pulp loquat can overwinter safely and can mature about one month earlier than that planted in the open field.

Description

technical field [0001] The invention relates to a method for cultivating white-fleshed loquats with double-film greenhouses for heat preservation and early maturation, and belongs to the technical field of fruit tree cultivation. Background technique [0002] Loquats are divided into two categories according to the color of the flesh, red flesh and white flesh. Among them, the white-fleshed loquat is deeply loved by consumers because of its sweet taste like honey, excellent flavor, soft and juicy, and has become the main loquat variety in Zhejiang, Jiangsu, Shanghai and other provinces and cities. At present, the market price of white-fleshed loquats is generally 30-60 yuan / kg, which is much higher than that of red-meat varieties. It is one of the fruit tree species with higher planting benefits. However, because the flowering period of white-flesh loquat is earlier than that of red-flesh loquat, the flowers and young fruits are more susceptible to frost than red-flesh loqu...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the defect that single-layer greenhouses cannot prevent freezing due to poor thermal insulation in the cultivation of white-fleshed loquats, and realize anti-freezing and early maturation of white-fleshed loquats by changing the facility structure to double-film greenhouses and supporting corresponding management technologies
