Root-limiting cultivation techniques of Grape

I believe everyone has heard of grape root-limiting cultivation, which greatly reduces the area of soil tillage, fertilization and irrigation, greatly saves the use of soil, fertilizer and water, and can realize the semi-automation and labor-saving of fertilizer and water management. greatly reduce labor costs, improve fruit quality and improve economic benefits. So how to limit the root of grape cultivation? What are the benefits of root-limiting cultivation? Come and have a look with the editor.

What is the root-limiting cultivation of grapes?

Grape root-limiting cultivation means to improve the control of root growth in a fixed space, regulate the vegetative growth and reproductive growth of aboveground parts, ensure that more nutrients are loosened into the fruit, and reduce fruit cracking in the later stage. This cultivation method has fewer grapevines per unit, but the yield per mu is more than 10% higher than that of the conventional method, the sugar content of the fruit is also increased by 2 degrees, and the planting cost per mu is saved by about 800 yuan.

2. Key points of root-limiting cultivation

This cultivation technique means that grape is cultivated in the soil with ultra-high organic matter to ensure the root growth quality and respiration quality. it is completely different from the fertilizer and water management of conventional cultivation, which applies fertilizer into the soil and makes use of the buffer of the soil. the fertilizer is absorbed by the root system, while the limited root cultivation is that the fertilizer directly touches the root system, limits the root system in a certain area, promotes a large number of absorbing roots, and improves the absorption and utilization rate of fertilizer. It is precisely because the fertilizer is in direct contact with the root system, it is necessary to adopt the integrated supply of fertilizer and water, to limit the concentration of fertilizer solution so as not to damage the root due to excessive concentration, and to limit the content of harmful substances such as heavy metals in the fertilizer solution; the base of this cultivation technique does not need fertilization in the early stage, and the plate should be properly expanded and fortified water-soluble organic fertilizer should be supplied at the same time after 3-4 years of cultivation.

1. Ridge cultivation

It means that after laying microporous non-woven plastic film on the ground, the soil rich in organic matter is piled on it, showing a ridge shape, and then grapes are cultivated on the ridge. This method is suitable for areas where the accumulated soil is not frozen, but the stability of soil moisture and temperature in the root zone is poor in summer.

2. Box cultivation

The grape is cultivated by filling the mixed soil in the root-limited cultivation container with box-basket structure or masonry structure, and the excess water can be left along the gap in contact with the soil under the box to avoid stagnant water. The disadvantages of this method are lack of water in the root region, unstable temperature and poor resistance to low temperature.

3. Pit cultivation

Dig a volumetric pit on the ground, the four walls of the pit and the bottom of the cushion micro-porous non-woven cloth and other diaphragm materials that can permeate but the root system can not penetrate, fill it with nutritious soil and plant trees in it.
