The excessive growth of grape shoots is also known as shoots. Sometimes it is because of the variety. The species with stronger tree vigor tends to have long branches; at the same time, trunk erection can cause prosperous growth; too much fertilizer or improper pruning can cause leggy. The long branches are mainly due to the unbalanced distribution of nutrients in the tree, the inability of better nutrient conversion between reproductive growth and physiological growth, and the lack of sufficient nutrient supply for the fruit. In the study, the plants with leggy plants had high GA and IAA levels before and after flowering. Production can be used to change the shape of the frame, wipe buds, topping, pruning and other measures to control the leg length, but the cost is time, higher cost, so fruit growers can choose to use growth regulators to control the growth of new shoots. From the early stage of shoot growth to the flowering of the grapes, it can be used to intelligently fill the vacuum of missing nutrients, regulate the growth and nutrition of fruit trees, and guard the tree body to thrive and develop positive energy, suppressing the secondary fruit (splitting fruit, stale fruit, pods). Result) Generate base source. To lay a solid foundation for high quality and high output.
