Root zone restriction is the use of physical or ecological means to limit the growth range of the grape root system to a certain volume, and regulate the growth of the above-ground branches and leaves, the fruit setting and the formation of fruit quality by regulating the growth environment, nutrient and water supply status of the root system.
In the past, farmers often used the techniques of "digging deep holes for planting, deep plowing and extensive fertilization and cultivation" when planting grapes, which made it difficult to improve the quality of the fruit. Root zone restriction breaks through the traditional cultivation theory of "trees with deep roots" and "deep roots and lush leaves". Years of research have shown that for the growth of grapes, it is not necessary to have "deep roots" in order to be "leaf", and limiting the range of root growth can also be "leaf.
The groundwater level in the south is high, and the root system is distributed in the soil layer with water, which often absorbs too much water, which affects the formation of sugar and peel pigment of the fruit. This is because the sugar content of the mature fruit is not high, the color is not good, and the flavor is weak. The main reason. The use of plastic film and other materials to limit the growth of the root system within a narrow range, the root system cannot extend to the outside of the root zone to absorb water, and the nutrients put into the upper layer of the root zone can also be fully absorbed by the dense root system and rarely lost.
Therefore, it can accurately supply water and nutrients according to the growth and development requirements of the grapes, and then control the growth of the branches and leaves on the ground, the fruit setting and the quality of the fruit. In northern regions, this technology can be used to grow vines and save water and fertilizer. At the same time, this technology can also be used to grow vines in saline-alkali land through partial soil improvement in the root zone, so as to reasonably develop and utilize saline-alkali land resources.
