There are three ways to apply micronutrients directly to seeds.

There are three methods for applying microelement fertilizer directly to crop seeds: dressing, soaking and seed coating.

Seed dressing: First, the quantitative micro-fertilizer is dissolved in water to form a dilute solution (general concentration is between 0.02% and 0.1%). Then, the micro-fertilizer solution is placed in a sprayer or a watering can and sprayed on the seed with a sprayer. While stirring, so that each seed evenly stained with fertilizer solution, the solution should not be too much, so as to avoid wrinkling seed coat, resulting in bad species. After the seeds are mixed, the seeds are spread out and allowed to sow.

Soaking: Take corn as an example. Dissolve first-grade (or seven-water) zinc sulfate into a solution with a concentration of 0.02% to 0.05%. Soak the seeds for 6 to 8 hours. Remove the seeds and let them soak to dry. . If the concentration of zinc sulphate solution is greater than 0.1%, it will affect the seed germination. The method of soaking and fertilizing requires the soil of the sowing place to have a good moisture content, generally above the jaundice. If the soil is arid and reaches the ash level, the soil around the sown seeds will consume a lot of water and affect the emergence.

Seed coating: The trace element fertilizer and the addition of a regulator into a certain viscosity of the solution, rolling in the coating machine for a certain period of time drying can be sown.

Oxygen Cylinder Filling System

ETR Oxygen Cylinder Filling System


By PSA principles, ETR PSA oxygen generators generate 93%±2% purity oxygen gas directly from compressed air. ETR oxygen cylinder filling plant is consisted of Atlas Copco air compressor, Parker dryer and filters, air buffer tank, ETR PSA Oxygen Generator, oxygen buffer tank, oxygen receiver tank, diaphragm oxygen booster, filling station and control cabinet.

Compressed air is purified through the air dryer and filters to a certain level for main generator to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The generator produces oxygen with PSA (pressure swing adsorption) technology, which is a time proven oxygen generation method. Oxygen of desired purity at 93%±2% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4bar pressure, then reach to 150bar to filling cylinders with an oxygen booster.
