Symptoms and countermeasures of deficiency of Chinese herbal medicines
First, nitrogen deficiency Chinese herbal medicines lack of nitrogen, the plant leaves old leaves yellow, fall off, the plant was pale green to yellow-green, the leaves become smaller, the elongation of new shoots is severely blocked, and premature aging also occurs. Supplementary treatment methods: Each acre can be topdressed with 15 kg of urea or 20 kg, can also be used for foliar recovery, spraying 1% -3% of urea diluent.
Second, phosphorus-deficient Chinese herbal medicines lack phosphorus, plant dark green, purple petiole, leaf thinning, smaller, plant dwarf, at the same time there are necrotic spots in the fruit. The yellow leaves of the base were yellowed, and the degree of loss of green was slightly lighter than that of nitrogen deficiency. Supplementary treatment methods: Each super acre can apply superphosphate 20 kilograms, or spraying 0.3% potassium dihydrogen phosphate solution on the leaves.
3. Potassium deficiency Chinese herbal medicine lacks potassium. The old leaves at the base of the plant show white green scars. The veins and leaf margins of the leaves and the tips of the leaves are dry. At the same time, due to the uneven growth of the leaf, a cup-shaped curl or shrinkage was formed. As the growth period prolonged, a "burning injury" was observed. The stem segments were thin and short, and the top branches and plants were severely fallen down. Treatment methods: Apply 13 kg of potassium sulfate or potassium chloride per acre. Foliar topdressing can also be performed by spraying 0.3% potassium dihydrogen phosphate dilute solution.
4. Calcium-deficient Chinese herbal medicines are deficient in calcium. The top leaves of the plants turn yellow and become hooked. They gradually die inward from the tips of the leaves and leaves. In severe cases, the tips of the roots and stems are ulcerated and necrotic. Supplementary treatment methods: Each acre can be followed by 15 kg of ammonium nitrate. Foliar spray can also be performed, spraying 2% calcium carbonate dilution.
V. Sulfur-deficient Chinese herbal medicines lack sulfur. The veins of the top leaves of the plants turn yellow-green, and the leaves are red or purple. Treatment methods: Apply 5 kg of agricultural plaster per acre, or apply 10 kg of ammonium sulfate and 1.5 kg of powdered elemental sulfur.
Six, iron-deficiency Chinese herbal medicines iron deficiency, the young leaves of the veins between the chlorosis gradually developed from yellow to white. In the case of moderate iron deficiency, chlorosis is limited to leaf margins. When severe, the entire leaf and veins are chlorotic and growth is severely inhibited. Supplementary treatment methods: can be followed by 0.3% of the ferrous sulfate dilution spray.
VII. Manganese-deficient Chinese herbal medicines lack Mn, and produce pulsating chlorosis on newly matured leaves. When severe, all the leaves on the plants become chlorotic. Supplementary treatment methods: The foliar spray of 0.1% manganese sulfate can be performed.
VIII. Boron-deficient Chinese herbal medicines suffer from a lack of boron. Small yellow spots appear near the center of young leaves and then expand to form larger yellow areas, but the veins remain green. Immature boron deficient leaves are thickened, distorted and distorted. Severely shorten the internodes and dwarf the plants. Supplementary treatment: 0.1% borax dilution can be sprayed on the foliage.
Nine, lack of copper copper deficiency Chinese herbal medicine, immature young leaves first showed a uniform light green, after the white, but the veins remain green. In severe cases, the growth point of new shoots will die, and the leaves will fall off when they are immature. Supplementary treatment methods: Each gram of copper sulfate can be applied to 1.7 kilograms, or 0.4% copper sulfate dilution solution for extra-root fertilizer.
X. Zinc deficiency Chinese herbal medicines lack zinc, plant stem top growth is blocked, internode shortening, showed dwarf status. Leaves twisted, lobular. On the old leaves, yellow veins appear between the veins, and white necrotic spots appear on both sides of the main vein, and the posterior veins and leaves thicken. Supplementary treatment methods: You can spray 1% zinc sulfate dilute solution in the early stage of growth, or 1.2 kg zinc sulfate per mu.
Eleventh, lack of molybdenum Chinese herbal medicines such as lack of molybdenum, the top of the plant leaves, leaf veins between the lack of green and leaf margin necrosis, leaf growth malformations, necrotic spots scattered on the entire leaf. Supplementary treatment methods: 0.02%-0.05 ammonium molybdate dilution solution can be used outside the root dressing.
Twelve, lack of chlorine in Chinese herbal medicines lack of chlorine, the first in the old leaves showed chlorosis, from the leaf edge to the development of the middle ribs, formed after the formation of patches, the leaves curled downward. In the case of severe chlorine deficiency, the growth of branches and leaves is inhibited and the elongation of the roots is blocked. Supplementary treatment methods: Each acre can be topped with 15 kg of potassium chloride or 10 kg of ammonium chloride.
Second, phosphorus-deficient Chinese herbal medicines lack phosphorus, plant dark green, purple petiole, leaf thinning, smaller, plant dwarf, at the same time there are necrotic spots in the fruit. The yellow leaves of the base were yellowed, and the degree of loss of green was slightly lighter than that of nitrogen deficiency. Supplementary treatment methods: Each super acre can apply superphosphate 20 kilograms, or spraying 0.3% potassium dihydrogen phosphate solution on the leaves.

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.
