Characteristics and Cultivation Techniques of Sweet Orange Pummelo
(I) Growth Result Habits
The sweet orange pomelo tree is strong and has a round head crown. The tip of the branch shoot has obvious advantages, and its branching and leafing forms are close to Wenzhou tangerine. There is a small thorn on the branch. The phenological period is similar to that of the mandarin orange, and the young and middle age is strong. More than 90% of the flowers are spent on leaves. The number and length of leafy squid were higher than those of other varieties of citrus. The maximum number of leafy squid was more than 35 cm and the number of leaves was 13 or more. The main results were spring shoots and autumn shoots, and the results were both inside and outside the crown. As a result, the period from July to late October is the period of fruit enlargement, and the fruit matures from the end of November to the beginning of December.
(B) Adaptability and stress resistance
Sweet orange grapefruit has strong cold resistance, and it has a 10 frame frame (10). The tip of the garden stepped on? Kind of disease L 鸾å挚 æ€ æ€ å©‰ã 婉ã 婉ã 婉ã 婉ã 婉ã 婉ã 婉ã . . . . . . . . . . . .?
Second, the main economic characteristics
(a) Little or no nucleus traits
The majority of fruits are seedless, with a small number of nucleated fruits of about 3-5 seeds per fruit. Currently, the work of selecting seedless individuals is still underway, and the non-nuclear origin is under study.
(B) Fruit Quality and Storage
The fruit is oblate, head-shaped, neat, dignified, with an average fruit of 230 grams. Peel orange, fruit surface is not smooth, peeling is slightly more difficult, but easy to pomelo. Orange yellow flesh, soluble solids content of more than 12%, soft and juicy, sweet, clear mouth, no sour taste, there are orange and pomelo aroma, fruit quality, regardless of size, eating similar. Mature from the end of November to early December, packed with thin-film single fruit, and stored at room temperature until the end of May of the following year. The fruit supply period of the product is particularly strong in citrus varieties.
(3) Early fruit and high yield
High in the sorghum anvil, late-maturing Wenzhou oranges and other trees, the second year on a large number of results, the third year of the strain up to 30-50 kilograms, more than 3,000 kilograms per mu.

2, planting density and planting: If it is a hillside, we must first dig into a horizontal belt more than 2.5 meters wide, and then in the middle of the horizontal belt dug planting or planting ditch, depth 60 cm, width 100 cm, in the planting ditch in the application Into the garbage and bar green fertilizer or green manure, a layer of fertilizer layer of soil, the top layer of subsoil and organic fertilizer separated by 15 cm, so that the root system does not directly contact with fertilizer, after each plant with 0.5 kg of calcium magnesium phosphate mixed with soil Cover the seedling root system and allow the root system to stretch in layers. If it is planted on a sunny day, water should be poured. For planned dense planting, 150 plants (1.53 m) will be planted in acres, and if planted permanently, 75 plants will be planted in acres (33 m). It can be planted every autumn from late September to early November and from mid-February to the end of March. .

The average tree size per plant was 0.2-0.6 kg of urea, 0.1-0.3 kg of potassium sulfate, and 0.2 kg of phosphate fertilizer. The results of the tree fertilization 4-5 times a year, fruit fertilizer 1 time, spring bud before 1 time, strong fruit promotion fertilizer 2-3 times, the amount of fertilizer was 30%, 20%, 50%, yield 2500- 3500 kg of garden, urea 100 kg per mu, 150 kg of superphosphate, 150 kg of potassium sulfate, 3 kg of borax, 100 kg of cake fertilizer or 1000 kg of bar fertilizer, the ratio of nitrogen, phosphorus and potassium is 1.0:0.5:0.8 .
4. Flower and fruit management: In years with a large amount of flowers, there is no need to keep flowers and fruit. In the year of small amount of flowers, 9201 grams of water can be mixed with 20-25 kilograms of water after being dissolved in alcohol. The sweet orange grapefruit has a single fruit weight, and the ratio of leaf to fruit should be maintained at about 40:1. The excess fruits can be sparsely removed. First, the disease, fruit and insects, malformed fruit, and dense fruit should be removed first. Bagging to produce pollution-free high quality fruit.
5, pruning: For excessive results caused by tree branches and branches of premature aging should be a short cut, promote the development of new shoots, in order to protect the annual yield and stable yield, to stay in the dense branches to stay weak; strong for tree vigor The results tree, cut off some cross-branch, and students leggy branches, serious pests and branches, hidden branches can be.

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.
