Embodiment 1

[0031] Adopt the seedless white grape vine of 7a (age 7 years) as object, and treatment area is 1.8 mus.

[0032] 1) Determine the date of the young fruit period of grapes based on the standard that the ear fruit setting rate reaches 80% as the beginning of the young fruit period.

[0033] 2) Use iron wire to connect the rack room bracket at 50cm above the canopy of the grape plants, and fix the sunshade net on the iron wire with tie wire. The shading rate of the sunshade net is 70%.

[0034] 3) Bind the water pipeline to the steel wire in the center of the grape trellis with wire tie. And start to install the micro-spray head at the head of the grape trellis, use a hose to connect the micro-spray head to the water pipeline, the distance between the micro-spray heads is 2m, and the location is 50cm below the scaffold until it reaches the end of the grape trellis, and the mist micro-spray time is turned on every day It is 13:00, the closing time is 14:00, and the flow rate of...

Embodiment 2

[0040] Except that the flow rate of the mist micro-spray head is 30L / h, all the other are the same as Example 1.

Embodiment 3

[0042] Except that the flow rate of the mist micro-spray head is 20L / h, all the other are the same as Example 1.

Abstract

The invention provides a device and method for regulating and controlling the vineyard microclimate, and belongs to the technical field of grape cultivation. The device comprises a sunshade net and mist micro sprinklers. The sunshade net is built above a canopy of grape plants; and the mist micro sprinklers are distributed below the canopy of the grape plants. Through double combination of the sunshade net and the mist micro sprinklers, the light intensity and the air temperature borne by the grape canopy are regulated and controlled to reach the microclimate where optimal photosynthetic organic matter of grapes is accumulated, and the problem that the quality of grape fruits is reduced due to photosynthetic noon break and strong light direct irradiation can be solved. The device providedby the invention can improve the quality of grape fruits such as size, color and luster, and the method is simple to operate and easy to implement.

Description

technical field [0001] The invention relates to the technical field of viticulture, in particular to a device and method for regulating the microclimate of a vineyard. Background technique [0002] Parts of Xinjiang have an extremely arid climate, especially in Turpan, where the annual rainfall is less than 25mm, while the annual evaporation is greater than 2500mm. However, its rich light and heat conditions are suitable for growing a variety of fruits, especially grapes. However, due to the excess of light and heat resources, the grapes in this area are prone to strong light, high temperature and low humidity stress. Especially when the light intensity exceeds the light saturation light intensity of grape leaves and the temperature exceeds 35°C (generally 1500μmol·m -2 ·s -1 left and right), will inhibit the photosynthesis of grapes. According to statistics, the light intensity in June and July in Turpan area exceeds 1500μmol·m -2 ·s -1 The period of time is from 11:45...
