When is the red spider's outbreak period? Every year from April to May and September to October, these two time periods are when the red spider is completely out of the year. When the red spider is seriously harmed, it will affect the growth of the crop and reduce the yield. Therefore, we must do a good job of prevention and control of red spiders in advance So how should farmers control the damage of red spiders? Next, Xiaobian will talk about the technology of spider mites and I hope to help everyone.
First, medication control, rational compounding drugs
When using the medicament to control the red spider, the compound dosage form medicine can be selected, and several single medicines can also be selected for the mixed preparation. It should be noted that while using a large amount of mixed chemicals to control insects, it may also cause phytotoxicity to crops. Therefore, when selecting a drug, it is necessary to use high-quality big-brand pesticides, and try not to be in the crops and young fruits. use.
Second, the timing of prevention
Spring red spiders will be high, this temperature can not be separated, so as long as the peak of the spider mites, the use of long-term insecticides to control the crops, can achieve good control results. When the spider mites are relatively small, the prevention and control can reduce the cost of controlling the red spider.
Third, attach importance to tactics
If the conventional control method does not achieve the desired effect, it can be cured by taking back the carbine tactics after the Red Spider. Apply a quick killing agent to the crops. On the fifth day after the dose of the drug drops and the eggs of the insects begin to hatch, spray a killing agent with a quick effect and long-acting effect. It can avoid the emergence of a new round of insect pests after hatching, and achieve the desired control effect.

The image measuring instrument is based on CCD digital image, relying on the powerful software capabilities of computer screen measurement technology and spatial geometry operation. After installing the special control and graphic measurement software, the computer becomes the measurement brain with the soul of the software and is the main body of the whole equipment. It can quickly read the displacement value of the optical ruler, and obtain the desired result instantly through the software module operation based on the spatial geometry; A graph is generated on the screen for the operator to compare the image with the image, so that the possible deviation of the measurement results can be identified intuitively.
Image measuring instrument is a high-precision optical image measuring instrument composed of high-resolution CCD color lens, continuous zoom objective, color display, video crosshair display, precision grating ruler, multi-function data processor, data measuring software and high-precision workbench structure.
The instrument is applicable to all application fields for the purpose of two-dimensional plane measurement. These fields include: machinery, electronics, molds, injection molding, hardware, rubber, low-voltage electrical appliances, magnetic materials, precision hardware, precision stamping, connectors, connectors, terminals, mobile phones, home appliances, computers (computers), liquid crystal television (LCD), printed circuit boards (circuit boards, PCBs), automobiles, medical devices, clocks, screws, springs, instruments, gears, cams, threads, radius templates, thread templates Wire and cable, cutter, bearing, screen, test screen, cement screen, screen plate (steel mesh, SMT template), etc.
