Root-limiting cultivation techniques of Grape

The purpose of grape root-limiting cultivation technology is to provide a new grape cultivation method, that is, the shallow planting of grape ridges and root-limiting planting technique. with this cultivation method, grape seedlings can enter the full fruit stage in only 15 months. and crown growth, fruit yield and quality can be artificially controlled. Ensure that nutrients such as fertilizer and water are mainly used to form fruits.

The soil is piled into ridges at a certain distance on the ground to be planted, and drainage ditches are opened on both sides of the soil ridges. the depth of the drainage ditch is 15-20 cm and the width of the drainage ditch is 20-30 cm. Add organic fertilizer to the surface of the soil ridge and mix it with the soil to form a nutrient soil layer of 20 Mak. 30 cm, and then plant grape seedlings on the nutrient soil layer. When planting grape seedlings, the seedlings must be planted shallowly, and the depth of the seedlings is 2-5 cm. After the grape seedlings produce new roots, cover the surface of the soil ridge with grape seedlings with 2-5 cm of organic fertilizer to form an organic fertilizer layer, and then cover a layer of orange stalk on the organic layer. The drip pipe is laid in the middle of the orange stem, and the grape seedlings are planted in the middle of the soil ridge. The distance between plants is 1.5-2.5 meters, and the row spacing is 2.5-3 meters. The dripping speed of the drip pipe ensures that the water content of the nutrient soil layer and the organic fertilizer layer reaches 45% 55%.
