Embodiment

[0015] A method for cultivating white-fleshed loquats with double-film greenhouses for heat preservation and early maturation, comprising improving the structure of the greenhouses, determining the time for film covering and film removal, and managing fertilizer and water after film covering, specifically according to the following steps:

[0016] (1) Set up double-membrane greenhouse structure: the width of the greenhouse is 8m, the top height is 4.5m, the shoulder height is 3m, and the length is 60m. Pipe, 3.5m long, 50cm of which goes deep into the soil; each column is 4m long, and the columns are fixed on the roof of the shed and connected by a vertical rod. The two ends are respectively connected with the card slots (2, on both sides of the shed, which play the role of fixing and tightening the shed film). A longitudinal rod (total of 4) is installed at the outer two ends of the inner and outer arch rods. The inner and outer films are fixed on the longitudinal rods throug...

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...
