The pruning of fruit trees generally pays attention to the branches and stems of the ground, and the role of root pruning is not valued. According to experiments, pruning the root system of fruit trees can not only extend the life of the tree body, enhance the vigor of the tree, but also make the fruit high quality and high yield. The effect is similar to pruning the branches and stems of fruit trees.
Time and method of root pruning: After harvesting the fruit of the fruit tree, it is better to prun the spring in the coming year. It is best to combine deep pruning and applying organic fertilizer at the same time. Every year, a ditch is dug around the canopy of the tree canopy. Two parallel trenches can be dug along the sides of the tree, deep enough to be 70-100 cm, and the roots with a diameter less than 1 cm can be cut to promote new root regeneration. Pruning year by year makes the root system more and more widely distributed, the absorption capacity is strengthened, and the yield and quality of fruits will be gradually improved.
Research experiments have shown that the senescence of fruit trees is mainly the aging of the root system. Many harmful germs invade the root system and gradually accumulate some toxic elements, causing many root systems to die continuously. Therefore, by pruning the root system, it is continuously updated to promote the metabolism of the tree body. At the same time, due to deep soil turning and fertilization, nutritional supplements and soil improvement are also enhanced, and the roots of the fruit tree are deeply and broadly planted. Its roots are deep and leafy, ensuring increased yield and income. Therefore, when pruning, you should not only pay attention to the branches, but also pay attention to the roots of the tree. This two-pronged approach is more beneficial to the quality and high yield of the fruit.

Thickener is a kind of biological gel that integrates thickening, suspension, emulsification, and stability. Thickener can improve the viscosity of the material system, keep the system in a uniform and stable suspension or emulsion state, or form gel. Most thickeners also have have the function of emulsification. It can be divided into two categories: natural and synthetic.
Thickener is widely used in food, cosmetics, detergent, latex, printing and dyeing, medicine, rubber, coatings, etc.
