Identify the weed species weeds, including grass weeds such as crabgrass, goosegrass, etc., broadleaf weeds such as amaranth, etc., as well as more intractable weeds with strong fertility such as Fragrant aconite, field bindweed, purslane, etc., according to the type and distribution of weeds, choose the right type of herbicide. Selection of herbicide varieties 1 Do not look at advertising to see the effect of control. In the case of uncertainty, the first choice is the ones that have been used in past years with relatively good results. These varieties have been tested for many years of production practices and are safe and effective. They can be used boldly. 2 For cornices, choose varieties. At present, most fields use mechanical harvesting of wheat, wheat bran, high grass, and general herbicide control effect is not good, can be quickly blocked or 52% of the new Xuanhuayi A control. 3 According to the time selected varieties. There was no time to apply herbicides when sowing, and corn was also emerged when we saw weeds. At this time, herbicides such as Yubao, Yubei and Fuziqing could be used. According to local conditions, reasonable herbicides have suitable varieties of herbicides, and they must be applied rationally. Otherwise, it would be difficult to achieve the desired control effect and even produce phytotoxicity.
Compacted Vacuum Suction Unit
ETR has independently developed an integrated vacuum pump unit composed of a water-ring vacuum pump, a gas-water separator, a vacuum solenoid valve, pipe fittings and an electrical control system. It is a simple, safe and reliable device that continuously serves the wards all day long, without occupying the ward space. The negative pressure is sourced from the vacuum pump unit.
