Disaster avoidance type greenhouse cultivation method for fruit tree in low-latitude plateau area

Abstract

The invention relates to a disaster avoidance type greenhouse cultivation method for a fruit tree in a low-latitude plateau area. According to the invention, a disaster avoidance type fruit-tree steel-frame greenhouse in the low-latitude plateau area is adopted; a layer of an anti-bird net covers the outer side of a greenhouse frame (1) from soil surface to the top part of the greenhouse frame; the outer side surface of the anti-bird net (3) is provided with a plastic greenhouse film (7); the outer side of the plastic greenhouse film (7) is provided with a waterproof cotton quilt (6); and a covering water film is arranged in the greenhouse frame (1). The growth period of the fruit tree is divided into a defoliation dormancy early period, a defoliation period, a blossom bud germination early period, a period from a blossom bud germination later period to a blossoming period, a full blossoming period, a period after flower withering to a fruitlet period, a fruit growth period, a fruit harvesting period, a preparation period before dormancy, etc., and the anti-bird net, the plastic greenhouse film, the waterproof cotton quilt, the covering water film and the ground are integrated together and used according to actual weather conditions, so the problem of disasters caused by severe weather change of winter and spring in the low-latitude plateau area is effectively solved.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for cultivating disaster-avoiding fruit tree greenhouses in low-latitude plateau areas. Background technique [0002] In order to advance the maturity period of fruits and improve the industrial benefits of fruits such as sweet cherries and peaches, it has become a common technology to cultivate fruit trees in a closed greenhouse environment. However, due to the coverage of the plastic greenhouse film, effective light such as ultraviolet light that affects the quality of the fruit is blocked, resulting in a decline in the internal quality of the fruit's soluble solids content and fruit fragrance. In the winter and spring seasons of fruit tree greenhouse cultivation, the solar radiation in the north is weak and the atmospheric temperature is low, so the closed insulation cultivation of fruit trees is very important; but the low-latitude plateau areas such as Yunnan ...

AI Technical Summary

Problems solved by technology

At this time, the plastic film alone in the greenhouse can no longer play the role of heat preservation and damage prevention, and the long-wave radiation of the earth at night will cool the greenhouse, and the daily temperature difference can reach 40°C (-8°C to 32°C) in strong frost weather. There is a temperature inversion phenomenon, that is, the temperature in the plastic greenhouse at night is lower than the outdoor temperature; such a drastic temperature change will cause great damage to the fruit trees

[0006] In addition, Yunnan is rich in biodiversity. In high-temperature and high-humidity greenhouses, the incidence of various diseases and insect pests is very high. A semi-open greenhouse cultivation technology for peach trees in low-latitude plateau areas (Chinese Patent No.: 201410475162.0) uses 20-mesh insect-proof nets and Waterproof quilts, but found in use that the 20-mesh insect-proof net will affect the light and ventilation in the shed, directly affect the disease resistance and fruit quality of fruit trees, and there is no insect pollination, manual pollination is required, which greatly increases the planting cost of fruit trees
