In agriculture, pests are a very annoying species for everyone, because their activities are at the expense of the health of the plant. There are many kinds of pests, some of them are eating leaves, fruits, etc. Some of them are harmful to plant roots, while others are direct drills of plant stems. Judging from the difficulty of prevention and control, the prevention and control of borer pests is the most difficult. Drilling pests are highly subtle and difficult to identify from the appearance of the plant, but the damage to the crop is indeed great. Therefore, aiming at the prevention and control of borers, modern agriculture used the perspective of agricultural insect pests to detect and achieved good control and prevention effects.
The hazard characteristics of borers are mainly woody plants and a small number of herbaceous plants. They mainly attack larvae, feed into empty holes and tunnels, impede the transportation of nutrients and moisture, and eventually cause trunks to be easily broken and withered to death. Drilling pests also spread diseases and cause great damage to crops. To effectively control the detection of borer pests, the most important thing is to achieve early detection, early prevention and prevention. Using the agricultural insect pest perspective instrument, X-ray can be used to inspect the pests hidden in the stems, and the detection work can be completed quickly and accurately without destroying the plant body. The agricultural insect pest perspective instrument not only greatly improves the detection efficiency, but also has an important application value in improving the report lamp of drill-boring pests.
There are many kinds of borers, which are harmful and difficult to control. It has always been a difficult point in the prevention and control of agricultural pests. Now, with the highly efficient detection apparatus for agricultural pests, these hated borer pests are no longer available. Efforts can be made not only to achieve early detection, to prevent its further expansion and proliferation, but also to reduce the production loss caused by borer pests through the implementation of timely and effective prevention and control measures, and to achieve significant reductions in drug use. Controlling damage, increasing production efficiency, and promoting the ecological development of modern agriculture.
Nitriding Single Screw and Barrel
1. When using new plastic, the remaining material of the screw should be cleaned. 2. When the temperature of the molten plastic is normal but black spots or discoloration of the molten plastic are constantly found, the rubber screw should be checked. 3. During processing, try to make the material plasticize evenly, and do not allow metal foreign matter to be mixed into the material to reduce the torque of the screw. force.
