1. Supplementary root fertilization deficiency
When crop root infertility is inconvenient, for example, in the later stage of crop growth, the root activity declines and the ability to attract fertilizers decreases; or when the soil environment is unfavorable for crop growth, such as excessive water, drought, soil acidity, and alkali, resulting in crop roots. Absorption is hindered, and crops need to resume growth quickly. If the method of root application cannot meet the needs of crops in time, only the foliar application can quickly supplement the nutrients and meet the needs of crop growth and development.
2. Quickly replenish nutrition
In the process of crop growth, the crop has already shown some nutrient deficiency, because the use of soil fertilization requires a certain amount of time nutrients to be absorbed by the crop, can not promptly alleviate the symptoms of crop nutrient deficiency. When foliar fertilization is used at this time, the nutrients can quickly enter the plant through the leaves to solve the problem of nutrient deficiency.
3. Give full play to fertilizer efficiency
Some fertilizers such as phosphorus, iron, manganese, copper, zinc, etc., if used as a root, are easily fixed by the soil and affect the application effect, while the use of foliar spray will not be limited by the soil conditions. For example, some fruit trees and other deep-rooted crops have relatively small amounts of certain nutrient elements. If traditional root fertilizers are difficult to apply to root absorption sites, they cannot fully exert their fertility. Foliar spraying can achieve better results. effect.
4. Economical
Various trace elements are indispensable nutrients during the growth and development of crops, but the application amount is very small, such as molybdenum fertilizer, and the application amount per mu is only several tens of grams. If the root application method is applied, it is not easy to apply evenly. Only adopting foliar spraying can achieve economic efficiency. According to research estimates, boron fertilizer is applied to foliar surfaces of general crops, and the boron utilization rate is 8.18 times that of basic plants. From an economic point of view, foliar spraying is more cost-effective than rooting.
5. Reduce soil pollution
Applying a large amount of nitrogenous fertilizer to the soil can easily lead to the accumulation of nitrate in groundwater and vegetables and cause harm to human health. About 75% of the nitrates absorbed by humans come from vegetables. If foliar fertilization is adopted, reducing the amount of soil fertilization can reduce the nitrate content in the plant and the residual mineral nitrogen in the soil. In salinized soils, soil fertilization may increase the concentration of soil solution and increase soil salinization. The adoption of foliar fertilizer measures not only saves the amount of fertilizer but also reduces the pollution of soil and water sources. It is an effective fertilization technique that can kill both birds and birds.
Containerized Oxygen Cylinder Filling System
ETR can combine all parts of the Oxygen Cylinder Filling System into a customized container, including air compressor, refrigerate air dryer, filters, buffer tanks, Oxygen Generator and oxygen booster and cylinder filling station.
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. With an oxygen booster, the oxygen pressure can reached to 15Mpa and fill in cylinders.
