Embodiment 1

[0021] A method for preserving freshness of live grape plants in an arch shed is characterized in that it consists of the following steps:

[0022] (1) Fertilize, in late September, top off the grapes in time, remove the growth points of the branches, and spray high-quality potassium dihydrogen phosphate on the leaves;

[0023] (2) ground treatment, before adopting live plant fresh-keeping, use thiophanate-methyl 50% wettable powder 600-800 times liquid to spray on ground and grape plant;

[0024] (3) Covering with film, when the frost comes in the middle and late October, when the outside temperature reaches 5°C, the grapes in the arch shed will close the vents at night to prevent it from being frosted; Covering with three membranes, attention should also be paid to strengthening the insulation around the arch shed, and a layer of windshield film or straw curtains should be installed around the arch shed to improve the heat preservation of the arch shed;

[0025] (4) Tempera...

Embodiment 2

[0029] A kind of technique for keeping fresh of living grape plants in a solar greenhouse in the method for keeping fresh of living grape plants is characterized in that it consists of the following steps:

[0030] (1) Delay the germination period. The germination period of land grapes is generally around mid-April. The solar greenhouse is used to cover the temperature with grass curtains during the day, and open the vents at night to ventilate, and the germination is delayed for about half a month;

[0031] (2) During the growth and development period, from germination to maturity, the entire vineyard is covered with a thin film. First, it can shelter from the rain. In addition, it can maintain the humidity in the shed without external interference, reduce the occurrence of diseases, and reduce the number of times of spraying;

[0032] (3) The mature period of color change. From mid-October, the focus of this period is to prevent frost. Frost is generally after mid-October. Wh...

Abstract

The invention discloses a fresh keeping method of a live grape plant and relates to the technical field of live grape plant fresh keeping. The method includes the arch shed live grape plant fresh keeping technology and the sunlight greenhouse live grape plant fresh keeping technology. The arch shed live grape plant fresh keeping technology includes the steps of firstly, fertilizing; secondly, processing the ground; thirdly, mulching; fourthly, controlling temperature; fifthly, controlling humidity; sixthly, harvesting. The sunlight greenhouse live grape plant fresh keeping technology includes the steps of firstly, delay budding stage; secondly, growth stage; thirdly, color changing and maturing stage; fourthly, live body storage stage; fifthly, harvesting and sleep stage. The fresh keeping method has the advantages that environment factors such as temperature, humidity and light in a facility are regulated manually, the method is sufficiently combined with the market requirement rule of fresh grapes, the optimal grape delay harvesting time is selected, and grape quality is increased while economic benefits are increased by delaying the harvesting 1-4 months.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping of living plants, in particular to a method for keeping fresh of living grape plants. Background technique [0002] Grape is a fruit with wide adaptability and high economic benefits. It has the characteristics of easy shaping, early fruiting and high yield, especially the promotion and popularization of grape protected cultivation in recent years. However, grapes tend to soften and rot at normal temperatures, and are susceptible to chilling damage, browning, and loss of flavor at low temperatures, which restricts the production, storage, transportation, and sales of grapes, and affects the enthusiasm of the majority of fruit farmers to plant grapes. In the existing technology, the fumigation method is a relatively common method. The fumigation method is to put grapes in a closed room, then put in the fumigant, and let it volatilize naturally. The commonly used fumigants include sec-butylami...
