Method for promoting the spring growth of grapes by using skirt membrane

Abstract

The invention relates to a method for promoting the spring growth of grapes by using a skirt membrane. The method comprises the following steps: after the grape tree is dormant, before the bleeding period, or when the daily average temperature is larger than or equal to 10 DEG C, namely, the effective activity temperature of the grapes is at the lower limit, the trunk of the grape is three-dimensionally covered by a plastic film and the skirt membrane is arranged, and a triangle is formed between the skirt membrane and the root distribution area of the grapes, and the concentrated distributionarea of the grape root systems in each planting row covers the triangular space range. The skirt membrane of the grape base tree body and the root distribution area form a triangle, the temperature can be quickly increased, so that the problem that the growth rate of the underground part of the plant and the growth rate of the overground part of the plant is solved. The method has the advantagesthat the operation is simple, the growth of the grape in spring can be remarkably promoted, and the timely transportation of the moisture and the nutrients by the root system can be promoted, reducingproduction caused by trunk drainage is reduced, the germination uniformity and the fruit setting rate are increased, and economic benefits are improved.

Description

technical field [0001] The invention relates to a method for promoting the growth of grapes in spring by using skirt film, in particular to a method of using plastic film three-dimensional covering similar to putting skirts on plants to improve the slow rise of ground temperature and the temperature of aboveground parts of grapes under certain cultivation ecological conditions. A method for rising imbalance belongs to the field of viticulture. technical background [0002] With the large-scale production of perennial fruit trees in facility cultivation, it has become more and more obvious that there are many physiological obstacles in the spring germination and growth stage of fruit trees in facilities.

[0002] With the large-scale production of perennial fruit trees in facility cultivation, it has become more and more obvious that there are many physiological obstacles in the spring germination and growth stage of fruit trees in facilities. The indoor temperature can reach about 20°C in winter under the condition of light, but the ground temperature rises slowly due to the influence of the soil medium, resulting in a large temperature difference between the underground and the ground, which is very different from the air/ground temperature difference during the germination period in the open air. This may be the main reason for the unbalanced germination and growth between the root system of the fruit tree and the shoots above the ground.

Facility cultivators use methods such as ridges and plastic film coverings in production. On the one hand, it is to increase the ground temperature, and on the other hand, it is t
