Potato potassium application technology introduction
Potatoes are good potassium crops, but the application of heavier N and P fertilizers in potato cultivation results in a large consumption of potassium in the soil, a decline in soil potassium supply capacity, and a disproportionate supply of fertilizer, thus limiting the yield of potatoes. Different soil conditions, potash fertilizer varieties and fertilization periods have different effects on potato yield and quality.
The results of the trial study showed that when the effective potassium content in the soil was lower than 100 mg/kg, the benefit of potassium application was significant, and the rate of increase in top-dressing potato with potassium fertilizer in the early stage of budding was the highest, and the starch content and the rate of large and medium tubers also increased. When planting potatoes, based on a certain amount of nitrogen and phosphorus fertilizers, after the application of acupuncture, cover soil to recover potassium fertilizer from 14 to 15 kilograms per mu. Potassium sulfate is more effective than potassium chloride.
ETR 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.
