After the grapes are harvested and before the winter, the nutrients of the tree are transferred from the harvest to the fruit before harvest, and the second peak of growth occurs in the root. At this time, fertilization is crucial. This is the reason for the high yield and quality of the grapes in the second year. It is decisive.
Foliar spraying fertilizer
During this period, the resistance of grape leaves was stronger, and the concentration of foliar fertilizer could be increased appropriately. Foliar spraying was performed with 0.5% urea and 0.5% potassium dihydrogen phosphate.
Fertilizer early
Immediately after fruit picking, immediately apply one-time quick-acting chemical fertilizer, and then apply topdressing to the late-maturing varieties before fruit harvesting, applying potassium sulphate ternary compound fertilizer or fruit tree-specific fertilizer 20 kilograms per mu.

The effect of applying base fertilizer after harvesting to defoliation is good. When the root system is used for supplementing fertilizer in an active period, not only the damaged root system can be restored, but also it can play a positive role in nutrient accumulation in the tree. Apply 3,000 kg of high-quality mixed fertilizer per acre, 15 kg of pure nitrogen, 15 kg of pure phosphorus, 25 kg of pure potassium, 25 kg of biological calcium fertilizer, 2 kg of zinc sulfate, 2 kg of ferrous sulfate, 0.5 kg of borax, 60% nitrogen removal 50% of potassium is left as topdressing, and the rest of the fertilizer is applied in a fertilization ditch with a depth of 30 cm and a width of 40 cm.
Whether it is to apply fast-acting fertilizers or base fertilizers in autumn, it must be watered in time to sink the soil, promote the rapid decomposition of fertilizers, restore tree vigor, and accumulate nutrients to provide adequate nutrition for the growth, flowering, and fruiting of the second year.
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.
