A look at the output of the current year. Under normal circumstances, the high and low output of the current year also indicates how much fruit can be harvested next year. In those days, when the quantity is large, pruning moderate and thick branches should pay attention to long release, and pruning with 3-5 buds is better. Leave 1-2 buds on weak branches, and choose reserve branches.
Second, look at the color of the branches. Experienced fruit growers can see the color of the branches and understand the lack of nutrition in the tree. The surface of the branches is brown and white, indicating that the degree of lignification is high and the tree body is in place. Moderate branches generally leave 3-4 buds, thick branches can leave 4-6 buds for pruning, thin branches 1 and 2 buds can become preliminary branches. The surface of the branches is brown and reddish, indicating that the nutrition of the tree is relatively poor. During pruning, one or two more buds need to be placed to increase the probability of ears.
Third, look at the thickness of branches. This method is a common pruning technique commonly used by ordinary fruit farmers. But to ensure the earing results, other factors must be combined. Relying on a single judgment, there will be more mistakes. As a result, the mother branch is like a human finger. After removing the thumb and the little finger, the other three fingers should be the best. Generally, 3-5 buds are reserved. If there is a lack of branches, one or two more buds should be left for pruning.
Fourth, if you can't do reasonable and scientific pruning, the phenomenon of grape racks moving out will be more serious in the next few years. In response to this situation, it must be updated in time to rejuvenate the tree and create more value. As a result, the renewal cannot be done overnight, and you must pay attention to it every year. In this way, the results can be updated correctly.

Plastic additives, also known as plastic additives, are compounds that must be added to polymers (synthetic resins) to improve their processing properties or to improve the properties of the resin itself. For example, in order to reduce the molding temperature of PVC resin, to make the product soft and added plasticizer; Another example is to add foaming agent in order to prepare light weight, anti - vibration, heat insulation, sound insulation foam plastics; The thermal decomposition temperature of some plastics is very close to the molding temperature, and the molding cannot be done without adding heat stabilizer. Therefore, the plastic assistant agent occupies a particularly important position in the plastic forming process. A class of auxiliary agents for plastic molding products, including plasticizer, heat stabilizer, antioxidant, light stabilizer, flame retardant, foaming agent, antistatic agent, mildew agent, colorant and whitening agent (see pigment), filler, coupling agent, lubricant, mold release agent and so on. Colorants, brighteners and fillers are not special plastics chemicals, but the general use of materials.
