Embodiment 1
[0024] Wine grapes planted in Penglai, Shandong in 2017, including the following steps:
[0025] 1) Ditching: According to the distribution characteristics of the root system of most wine grapes, the width and depth of the planting ditch are set to 80 cm, that is, the grape planting ditch is opened according to the specifications of 80 cm wide and 80 cm deep.
[0026] 2) Lay side membranes in the ditch: Cut the shed membrane not less than 0.15mm thick to 80cm wide, attach it to both sides of the planting ditch wall, then backfill the planting ditch in the order of organic fertilizer and surface soil, and water after backfilling Settle down and then proceed to vinecolonization.
[0027] 3) Overground coverage: On July 7, 2019, the rainfall was 15.0 mm, equivalent to 3.2 cubic meters of drip irrigation in the root area. Afterwards, shed film was used to cover the upper part of the planting row area to prevent excessive rainwater from flowing into the root area in the rainy seas...

[0036] Example 2 Reconstruction of the Senior Garden
[0037] The mature wine-making vineyard planted in Penglai, Shandong in 2013, including the following steps:
[0038] 1) In mid-March 2019, lay the side film in the ditch, open a ditch with a depth of 80 cm at 40 cm on both sides of the planting row, and stick a film not less than 0.15 mm thick to the ditch wall and backfill it.
[0039] 2) Overground coverage: On July 7, 2019, the rainfall was 15.0 mm, equivalent to 3.2 square meters of drip irrigation in the root area. Afterwards, shed film was used to cover the upper part of the planting row area to prevent excessive rainwater from flowing into the root area in the rainy season, so as to play The purpose of isolating rainwater, improving quality, controlling growth, and enhancing winter performance.
[0040] 3) Precise water regulation according to the phenological period:
[0041] a. From April 10 to April 28, 2019: The cumulative precipitation on April 10, 14 and 23 ...

Abstract
The invention relates to an accurate moisture control cultivation method applied to wine grapes, and belongs to the technical field of agriculture. The invention provides a reasonable wine grape cultivation method capable of accurately regulating and controlling the water content so as to avoid adverse effects on wine grape cultivation caused by improper water supply in the growing season. Fruit grains are reduced through water stress in the young fruit expansion period, and the proportion of peels and seeds rich in flavor substances in the fruit grains is increased; and more assimilation products are distributed to fruits through moderate stress of moisture from the color changing period to the mature period, and the content of flavor substances in the fruits is increased.
Description
technical field [0001] The invention relates to a cultivation method for precise control and control of water applied to wine grapes, and belongs to the field of agricultural technology. Background technique [0002] At present, the cultivation of wine grapes adopts conventional cultivation methods and is planted by traditional ditching technology, that is, after the ditch is loosened, organic fertilizer is applied to the base of the planting ditch, and then the soil is backfilled, and the soil is irrigated and then planted. The disadvantage of this planting method is that it is difficult to adapt to the continental monsoon climate in the main wine grape producing areas in China. Excessive precipitation in summer causes the soil to be in a condition of high water content or even saturated water content for a long time, resulting in excessive vegetative growth and poor fruit quality and brewing performance. Low, the plants also have poor overwintering performance due to insuf...
