At the same time, if two or more herbicides are mixed, the herbicidal spectrum must be different, but the applicable crops, period and method of use should be consistent and basically the same; when the wettable powder is mixed with the emulsifiable concentrate, the wettable powder should be dissolved in a small amount. The mother liquor is made in water, and then the emulsifiable concentrate is added; when the liquid is first filled, the semi-spray water is first added, and the second diluted pesticide mother liquor is added, and finally the sufficient water is added, and the mixture is fully shaken and sprayed.
Note: Chlorpyrifos cannot be mixed with alkaline pesticides . To protect bees, avoid using them during flowering. All crops should be discontinued before harvest. Poisoning is sent to hospital for treatment, atropine can be injected.

2. Electroplating: The quality of the electroplating surface is the most intuitive expression of the quality of the faucet. The surface plating is mainly nickel and chromium, so that it achieves a smooth and bright effect. Good quality faucets will undergo many tests, such as salt spray test, water test test, gas test test, etc., to ensure the durability of the faucet.

Therefore, it must be paid attention to what materials the equipment is made of, and not all countries have such high standards as Germany.
