How to water the apple orchard in spring*********
In order to make the spring shoots grow and stop early, one week after flowering, that is, in late April, the orchard should be hydrated in time, because the flowering and budding of fruit trees consume a lot of water and nutrients, so enter the orchard in May as much as possible. No watering is good for the spring shoots to stop growing. In June, the apple orchard will enter the period of flower bud differentiation. At that time, water should be properly controlled and watering should enter July, such as effective rainfall in July. Postponed later. Therefore, the orchard must be watered in late April, otherwise, the fruit trees will not survive May and June safely. Disclaimer: Some articles on this website are transferred from the Internet.

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.
