Modern agricultural production promotes green environmental protection, so insecticide control, orchard, tea plantation, vegetable plantation, etc. all prefer green prevention and control technology. Among them, the use of yellow wormwood to trap pests is a low-cost green prevention and control method. The agricultural field is widely used, and in the process of use, we will find that these sticky board are not only yellow, but also blue, red and other colors, so what is the difference between the yellow and blue boards? What? Let's announce it for everyone.
In the case of the yellow and blue boards, the effect of the armyworm is the same, but the color is different, and because of the different colors, the types of insects attracted by the yellow board are different. For example, the yellow body of the armyworm can trap all kinds of small flying insects and small black flying. The specific can be trapped and killed by whitefly, whitefly, aphid, small moth, yellow curved beetle, leaf miner, thrips, spotted dive. Fly, pear stem bee, black-winged whitefly, tea green leafhopper and a variety of Diptera pests. The blue plate is mainly targeted to trap the thrips and various flies (such as leaf miners), and the effect is targeted and trapped. In short, the yellow board attracts a wider range of insects, and the blue board insecticide is more targeted.
Due to the different types of trapping insects in the yellow and blue boards of the armyworm, in the process of use, we should reasonably select different stick boards according to the development characteristics of the pests in the planting area. The wormwood board is physically trapped and killed, non-chemical agents, safe for humans; simple suspension, maintaining the hanging state can continue to trap and kill, the normal pest control, its advantages are very obvious, so in the current vigorous development of green agriculture, in organic ecological agriculture The use of sticky yellow slabs in plantations can avoid the use of pesticides in the growth of agricultural products, reduce the harm, improve the quality of agricultural products, increase the income of farmers, and be loved by consumers.
Aluminum alloy parts are widely used in many industries. There are many processing methods for aluminum alloy products, such as CNC machining, extrusion molding, die casting, gravity casting, forging, sand casting and so on. Each of these processing methods has its own advantages and characteristics, and some are also determined according to the structure of the product. Aluminum investment casting can reduce mold development time and cost. Precision castings with complex structures can also be easily realized with short mold development time. And it is suitable for small batch and large batch production.
SCZY is very professional in the production of metal products, especially in investment casting and precision CNC machining. We can analyze the product structure and other aspects, and can make suggestions for improvement or optimization of the unreasonable aspects of the product structure to ensure the stability of subsequent mass production. Our in-house precision CNC machining can ensure the accuracy requirements of the product, and the accuracy can reach ±0.01mm under normal conditions. We are more than happy to solve all problems.
