1. Green cauliflower. In fertilizer nutrients, nitrogen and phosphorus are most needed in the whole growth period, especially in the bulbous expansion stage, and potassium fertilizer is required after flower bud differentiation. Among the trace elements, boron and molybdenum are most needed. The production of 1000 kilograms of green cauliflower requires 2.5 kg of pure nitrogen, 1.1 kg of phosphorus pentoxide and 2.9 kg of potassium oxide. Before planting, 2500 kg of organic fertilizer was applied per mu, 100 kg of biological organic compound fertilizer, 50 kg of urea, 20-25 kg of superphosphate and 30 kg of potassium sulfate. Into the rosette period, the first topdressing, applied 4 kg of pure nitrogen per mu, 6 kg of potassium oxide. The second time after the rosette was top dressing, 2.5 kg of pure nitrogen and 4 kg of potassium oxide were applied per acre. In the initial stage of bulb formation, 0.2% to 0.5% borax can be sprayed from the roots.
2. Cherry tomatoes. In addition to nitrogen, phosphorus and potassium fertilizers, pay attention to calcium and boron fertilizers. The production of 1,000 kilograms of cherry tomatoes requires 3.85 kilograms of pure nitrogen, 1.15 kilograms of phosphorus pentoxide, and 4.44 kilograms of potassium oxide. Before planting, 5000 kg of organic fertilizer was applied per mu, 200 kg of biological organic fertilizer, 50 kg of urea, 30-50 kg of superphosphate, 40 kg of potassium sulfate, 100 kg of calcium fertilizer, and 1.5 kg of borax. Generally when the first fruit begins to swell, it can be topdressed for the first time, with 5 kg of pure nitrogen per acre and 6 kg of potassium oxide. The second time the top dressing is harvested at the first time, when the second ear is swollen, 5 kg of pure nitrogen per mu and 6 to 7 kg of potassium oxide are applied. The third fertilizer is harvested in the second fruit, the first
When the three spikes are swollen, 4 kg of pure nitrogen per acre and 5-6 kg of potassium oxide are applied.
3. Dutch beans. During the seedling stage, nitrogen fertilizer was applied to supplement the phosphorus and potassium fertilizers during the growth period, and molybdenum and manganese fertilizers were added. The production of 1,000 kg of Dutch beans requires 2.4 kg of pure nitrogen, 0.8 kg of phosphorus pentoxide and 5.7 kg of potassium oxide. Before planting, 2500 kg of organic fertilizer was applied per mu, 100 kg of bio-organic compound fertilizer, 20 kg of urea, 25-30 kg of superphosphate, 40 kg of potassium sulfate, and 0.5-1 kg of manganese sulfate. Into the extension of the cranberry period, the first topdressing, applied 3 kg of pure nitrogen per acre, potassium oxide 4 ~ 6 kg. In the flowering and pod stage, the second top dressing is applied. The pure nitrogen is 2 to 2.5 kg per mu, and the potassium oxide is 3 to 5 kg. Spraying 0.02% to 0.05% ammonium molybdate during flowering.
4. American celery. The demand of celery for boron is relatively large. The addition of zinc fertilizer can reduce the nitrate and nitrite content of fresh vegetables. The production of 1,000 kilograms of celery requires 2 kilograms of pure nitrogen, 0.93 kilograms of phosphorus pentoxide and 3.9 kilograms of potassium oxide. Before planting, 4000-5000 kg of organic fertilizer is applied per mu, 150 kg of bio-organic compound fertilizer, 40 kg of urea, 25-35 kg of superphosphate, 40 kg of potassium sulfate, and 1-1.5 kg of zinc sulfate. The plants entered a vigorous growth period and the first topdressing was performed. Each acre applied 3 kg of pure nitrogen and 5-6 kg of potassium oxide. After entering the 3rd top-dressing in the second half of the month, 2~2.5 kg of pure nitrogen per mus, and 4~5 kg of potassium oxide were applied. Strong growth phase can be sprayed with 0.2% to 0.5% borax.
Removable Oxygen Cylinder Filling System
Removable Oxygen Cylinder Filling System
Compressed air is purified through the air dryer and filters to a certain level for main plant to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The plant produces oxygen with PSA (pressure swing adsorption) technology, which is a time proven oxygen generation method. Oxygen of desired purity at 93%±3% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4bar pressure and fill in cylinder with an oxygen booster and compress the oxygen purity to 150bar.
With a customized container, all the parts can be involved in, and removable with a vehicle.
