Summer nursery chemical weeding effect is good
Beefgrass, foxtail, sedge and other nursery weeds not only affect the appearance and appearance, but also breed a lot of pests and diseases , and compete with the seedlings for water and nutrients, delay the time of seedling emergence, resulting in decreased seedling rate and increased production costs. Manual weeding is labor intensive and inefficient. If you use a chemical herbicide to weed, you can get twice the result with half the effort. Magnetic Pump have the magnetic seal, pump no leakage, safety, stable operation. Widely used in chemical industry and food industry. we have Magnetic Gear Pump, magnetic centrifugal pump, magnetic Screw Pump and magnetic rotor pump. base on all kind of pump's properties, pump be installed a magnetic coupling, the conveying medium has no leakage and the working environment is clean and tidy. No need to change the seal, easy to use and easy to operate. Depending on the medium being transported, the working environment is different and different pumps are selected.

First, the spraying time. The first spray was carried out in late June. Due to the summer season, the temperature is high, the humidity is high, and the weeds have high respiration intensity, which is beneficial to the absorption of chemical herbicides, and the efficacy is relatively fast. When spraying, choose weather conditions with clear skies, plenty of sunshine, no winds, and high temperatures. After the first spraying, the effect began to decrease in about 40 days, and then sprayed several times, the field weeds can be removed.
Second, the concentration of application. 10% of the glyphosate water is in the range of 1% to 2%, 20% of the gram-free water in the 0.5% to 1%, and 5% of the fine grass emulsion in the range of 0.1% to 0.3%. About 50 kg of spray liquid per acre.
Third, chemical weeding saves labor and time, the cost is low. A laborer weeds 0.5 to 0.7 mu per day, the weeding is not thorough, there are residual grass roots in the soil, and will soon re-emerge. And a labor force sprays about 10 mu per day, and all the weeds that are sprayed with the liquid medicine die, leaving no grass roots. In terms of cost, manual weeding requires 50 to 80 yuan per acre, while chemical weeding costs less than 10 yuan per acre.
