With PSA principles, ETR medical PSA Oxygen Generator can produce 93%±3% purity oxygen gas directly from compressed air. Compared with
traditional Bulk liquid oxygen and cylinders oxygen, ETR on-site PSA oxygen
generator can reduce cost down to 50 percentages. They can produce oxygen by
your will, overcoming the limits of distance, location and transportation.
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%±3% is delivered to oxygen buffer tank for smooth supply
of product gas. Oxygen in buffer tank is maintained at 4bar pressure.

During the whole life of rice, we must go through two different stages of vegetative growth and reproductive growth. The vegetative growth stage includes the seedling stage and the tillering stage, and is mainly the growth of the vegetative roots, stems and leaves, and accumulates nutrients for reproductive growth. The goal of fertilization at this stage is to promote tillering and form strong seedlings to ensure that there are sufficient panicles per unit area. The formation, growth, and flowering of the genital organs are strong. This stage of fertilization is centered on the promotion of large spikes, many grains, and grain filling.
Nitrogen, phosphorus, and potassium are nutrient elements that require large amounts of rice and lack of soil. The absorption intensity, absorption amount, and proportion are different due to variety, soil, climate, and cultivation, fertilization, and other conditions. Generally, every rice is produced. For 100 kg, about 1.6-1.9 kg of nitrogen, 0.8-1.3 kg of phosphorus, and 1.8-3.8 kg of potassium need to be absorbed, and the ratio of the three is about 1:0.5:1.3. The results showed that the nutrient contents of the plant during the growth stages of the early and late rice in the double-season rice were generally highest in the period from returning to the tillering stage, and the phosphorus and potassium were the highest in the jointing stage; the amount of nutrients absorbed by the rice in each stage of growth was double-season. Due to the short growth period of early and late rice, the absorption of nitrogen, phosphorus and potassium elements only forms a peak within 2-3 weeks after transplanting. However, due to the longer growth period, the absorption of three elements in single-season rice is generally Two peaks of uptake of fertilizer were formed at the peak of the tillering period and the later period of spikelet differentiation. Therefore, fertilization must be based on these laws of rice and fertilizer absorption characteristics, to fully meet the needs of rice fertilizer peak for a variety of nutrients.
Rice fertilizer use technology
Rice is the most important food crop in China. Fertilization of rice is an extremely complex issue. It is necessary to determine suitable fertilization time, fertilizer amount, fertilizer type, and fertilization method according to the characteristics of rice varieties such as nutrient characteristics, fertilizer properties, soil, and climate. The application of the fertilizer to obtain the highest utilization rate and the best economic efficiency, to achieve high yield, high quality and high efficiency.
