Weeding herbicides are the most sensitive to weeds in order to increase weed control. The selection of rice in the herbicide resistant to the strongest growth period in order to ensure the safety of seedlings. In general, weeds are most sensitive to herbicides during the seed germination stage and seedling stage, where herbicides are most likely to exert their effect. Rice plants are most sensitive to herbicides during the bud stage and the 4-leaf stage and are prone to phytotoxicity. The application of herbicides at these stages of growth should pay attention to the concentration of the agents. The application time of herbicides should be combined with the time of rice transplanting. For instance, when prometryn is used to control tooth grass in paddy fields, it must be applied 15-20 days after the rice is transplanted. If it is to prevent common conventional weeds, it must be the best after 10-15 days of rice transplanting. Most of the chemical weeds in transplanted paddy fields are mainly closed by soil after transplanting. Usually 3-7 days after transplanting, they are mixed with soil or mixed with green manure to control weeds, annual broad-leaved weeds and Cyperaceae weeds. . If dibenzyl chloride is used, it can be sprayed and sprayed for 2-3 weeks after transplanting.
Zns Window are flat, plane-parallel plates that are often used as protective barriers for electronic sensors or detectors from outside environments. Optical Windows should be selected based on the material transmission or mechanical properties of the substrate. Optical Windows do not cause change in the magnification of a system. Worldhawks` Optical Windows are offered in a variety of substrates, such as Germanium (Ge), Silicon (Si), N-BK7(H-K9L), UV Fused Silica, Zinc Selenide (ZnSe). Multiple anti-reflection coating options are available for the Ultraviolet (UV), visible, or Infrared (IR).
