Problems solved by technology

[0018] However, with the continuous improvement of grape yields, the grape planting area in my country has rapidly expanded; coupled with the application of advanced planting techniques and cultivation facilities, the yield per unit area of ​​grapes has continued to increase; in addition, grapes have strong seasonality and weak deep processing capabilities. Grapes are concentrated on the market, grape prices fluctuate in a hyperbolic manner, and the planting risks of growers continue to increase

Embodiment 1

[0042] Moldovan grapes were used as the experimental variety. Only use the cover measures in winter and spring for comparison in the same field, and set up 2 treatments, each with 15 mu.

[0043] (1) Test treatment:

[0044] A Shading treatment: Covering measures in winter and spring are adopted, that is, two layers of shading are carried out from January to reduce the field temperature. The covering layers are reflective film and shading net respectively.

[0045] Control treatment B: According to the traditional cultivation mode, no shading measures were adopted.

[0046] Other planting methods and management measures are the same, and are carried out according to conventional planting and management methods.

[0047] (2) Phenological period observation

[0048] Germination period: the date when the first leaf of 50% of the plants spreads out (expressed in month / day, the same below). Maturity: The date when the fruit of most grapes begins to soften and change color to ta...

Embodiment 2

[0053] Red Globe grapes were used as the experimental variety, and only a single layer of shading net was used in winter and spring, and the effects were compared in the same field. Two treatments were set up, each with 10 mu.

[0054] (1) Test treatment:

[0055] A Shade treatment: Only a single layer of shading nets in winter and spring is used to cover them, that is, shading with shading nets is carried out from January to reduce the field temperature.

[0056] Control treatment B: According to the traditional cultivation mode, no shading measures were adopted.

[0057] Other planting methods and management measures are the same, and are carried out according to conventional planting and management methods.

[0058] (2) Observation of phenological period: the method is the same as that of Example 1.

Embodiment 3

[0063] Kyoho grape was used as the experimental variety, and the winter and spring mulching measures and summer mulching measures were used for comparison in the same field. Two treatments were set up, each with 7 mu.

[0064] (1) Test treatment:

[0065] A Shade treatment: Adopt single-layer coverage measures of shade nets in winter and spring and cover measures in midsummer. That is to say, shading and covering with shading nets were carried out from January to reduce the field temperature, and single-layer mulching was carried out intermittently during continuous sunny days and temperatures > 35°C from July to August.

[0066] Control treatment B: According to the traditional cultivation mode, no shading measures were adopted.

[0067] Other planting methods and management measures are the same, and are carried out according to conventional planting and management methods.

[0068] (2) Observation of phenological period: the method is the same as that of Example 1.

Abstract

The invention discloses a grape sunshade cultivation technique. According to the physiological characteristic of grapes, i.e. the characteristic that environmental temperature directly influences the progress of growth and development, grape cultivation facilities or rainproof facilities are used as supports. The supports are covered by sunshade materials at different periods. The sunshade materials are laid at a single period in winter / spring or at two periods in winter / spring and midsummer. A single layer or two layers of reflecting films and sunshade nets are used as the sunshade materials in winter / spring to reduce field temperature. A single layer of sunshade nets is used as the sunshade materials in midsummer to prolong two growth and development periods, i.e. the dormant period and the fruiting period of the grapes, so as to finally achieve the goal of offering the grapes in the market at off-peak time.

Description

technical field [0001] The invention relates to a shading cultivation technique for grapes, which is a key cultivation and planting technique for delayed budding and delayed ripening of grapes. Background technique [0002] Grape is one of the three major fruits in the world and plays an important role in fruits. Grapes are rich in sugar, organic acids, proteins, vitamins and other nutrients. It is a fruit suitable for all ages. At the same time, the nutritional value of grapes is increasingly recognized by consumers. Deeply processed food has become a necessity of people's life. With the improvement of people's living standards, people's increasing demand for grapes and the huge economic benefits of staggered peak grapes have prompted the research work on extending the grape supply period to the maximum extent and avoiding the peak supply period of grapes in summer. [0003] In grape production, temperature plays a decisive role in the whole process of grape growth and de...
