1, open a row of drainage ditch, do a good job of seedlings, wash seedlings, spray fungicide in time, topdressing quick-acting fertilizers, promote recovery of production, prevent the spread of diseases, replanting and replanting work. 2, do a good job of "two diseases and two pests" prevention and control work. Rice planthoppers: We must promptly check and pay close attention. In the Waseda, there are more than 20 plots per phytoplasma, and more than 5 plots of medium rice are listed as control objects. Pharmacological use of 25% buprofezin 40-50 g/mu, or 25% imidacloprid 15-25 g/mu. Rice leaf roller: One hundred and twenty-two larvae should be controlled. The agent used was 48% chlorpyrifos 80-100 ml/mu. Rice blast disease: For fields where leaf blast or susceptible varieties have occurred, use 75% tricyclazole 20-30 g/mu. Rhizoctonia solani: The plots containing more than 30% of the clumps should be treated with antibiotics. The drug is selected from 5% utomycin 200 ml/mu or 40% rice bran 100 ml/mu.
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.
