Glyphosate is not a herbicide that kills buddha from the beginning of its birth. A considerable part of the weeds has natural resistance to it, such as linseed, leech, lotus, bamboo flower, white wine grass, shovel, crabgrass, sweet potato , Kochia scoparia, Cinnamomum camphora, Florida calla lily, Setaria viridis, Big fruit Sesbania, Amaranthus, Solanum nigrum. If planting crops are associated with these weeds, give up using glyphosate.
In the course of more than 40 years of development, more “weak†weeds that had once fought in front of glyphosate have evolved and made glyphosate helpless. The representative weeds are Tongquan grass, communis grass, yellow leeks, purslane, rat grass, iron leeks, field bindweed, chicory, and so on. Their commonalities are very insensitive to glyphosate, Strong resistance, single use of glyphosate can not be effectively controlled. In 2006 and 2010, China reported that resistance to glyphosate was caused by small fly and tendrilgrass. In particular, it has already become dominant weeds and vicious weeds in no-tillage cultivation areas and plantations in southern China. The spread of resistance has become increasingly serious and has become an insurmountable problem.
The problem of drug resistance is unavoidable, and the mixed application is a good countermeasure.
Mixed herbicide treatment with stems and leaves. Glyphosate is not ideal for control of some perennial grasses, such as radicchio, chevalier, and euphorbia. In the production, it can be mixed with phenoxy carboxylic acid herbicides such as 2,4-D, which not only has good control effect on small weeds and other weeds, but also can improve the control effect on sedge and broadleaf weeds.
Mixed with soil treatment herbicides. Glyphosate has low soil activity and can only effectively control weeds that have been excavated. The weeds in production are generally spotted and occur one after another, causing constant harm. To solve this problem, glyphosate can be mixed with some herbicides with high soil treatment activity. In this way, "killing one" can not only significantly extend the effective period of the herbicide, but also save the cost of repeated application and reduce the damage of weeds.
We may have heard of the Zoom Bullet Camera, so what is the Zoom Bullet Camera/ Bullet Zoom Security Cameras/ Bullet Zoom Digital Cameras/ Smart Zoom Bullet Camera/ Zoom Lens Bullet Cameras/ Zoom Bullet Camera HD? We know that the Bullet refers to the camera shape, so what about the Zoom? Actually, the Zoom refers to a type of the camera lens. Today let me introduce the camera lens for you.
I have introduced the camera lens and 2 classifications for you before. Today please let me introduce another parameter of the camera lens for you---the Wide Dynamic.
So what is the Wide Dynamic?
The Wide Dynamic actually refers to the brightness ratio of the brightest and darkest parts of the image that the user can see at the same time via the camera. The Dynamic Range broadly refers to the changing span of a changing thing, that is, the range from the lowest point and the highest point of its changing value, which is usually described as the difference between the highest point and the lowest point. Well, the Ddynamic Range of a camera refers to the ability of the camera to adapt to the light reflection of the scene in the shooting scene, specifically the range of brightness (contrast) and color temperature (contrast); which means the camera's adjustment range of the "darkest" and "brightest" of the image, or the ratio of the lightest tone to the darkest tone in a still image/video frame. And the hue can show the precise details in the image or frame. As the ratio of the two tones, the unit of the dynamic range can be decibels, bits, files, or simply expressed as a ratio or multiple.
The Wide Dynamic Camera Technology is a technique by which the user can see the characteristics of the image under very strong contrast via the camera. In some occasions where the contrast between light and dark is too large, due to the limitation of the CCD's photosensitive characteristics, the background of the captured images will be easily too bright/the foreground of the captured images will be easily too dark. Later, Because of the wide dynamic technology emerged, and this problem has been solved.
So how about the applications of the Wide Dynamic Camera?
The Wide Dynamic camera is usually applied when the light environment is still ideal but the details of the target object cannot be obtained. That is to say, the wide dynamic technology is mostly used in places where light and dark alternate. When the surveillance camera cannot achieve low-illuminance monitoring, the wide dynamic technology needs to be used to "fill the light". In terms of the surveillance camera applications, the ordinary surveillance camera captures the images with the clear background but the dark foreground, while the wide dynamic camera can capture the images with both the clear foreground and background.
The Wide Dynamic Camera is usually applied to the Highway toll system, the Electronic police system, the City Commercial Street and so on; which is very useful and has brought much convenice to our life.
In a word, I hope that the introducton of the Wide Dynamic can make all of us know more about the Zoom Bullet Camera and the whole video monitoring field.
