It's called the "china lee king". The beauty of the fruit, the colour of the gold, the skin, the small amount of the kernel, the crumbless, the sweet and sweet honey, the sugary, the low sour, and the fragrance of the fragrance, which combines the two advantages of orange beauty and the fine, skin-defeated nature of citrus, are so difficult to compare with other citrus species that they are dubbed as kings of citrus。
Introduction to name
The natural hybrid of oranges and oranges, with the dual advantage of oranges and oranges, is the rare breed of citrus farmers in the guangdong qing region, which has been awarded honors such as the chinese fruit circulation association, which has important economic value. The beauty of pure congee, yellow fruit, thin skin, crumbs, sweet honey, high sugar, low acid and fragrance, concentrates on the two advantages of orange beauty and orange meat, which is fine and skin-defeating. De qing is the main source of kampuchea and has the honour to name it “the village of kampuchea, china”。
It's also called the emperor's home or the princess orange. According to the examination, the kampuchea, which originated in jungshan, the city of guangdong, is an excellent breed of farmers. Cultivation has a long history and has been carried back to tang dynasty and has already been planted in the tsang dynasty. In the years of north song
The court was listed as a tribute for the emperor and was therefore named the “golden log”。
Form characteristics
The ginomets are beautiful, orange to orange red, thin and juicy, juicy, sweet and low acid, unique and popular to consumers. Before the early 1990s, however, kimmel was grown only on a small scale as a local specialty fruit. Since the mid-1990s, the deking county commission, county governments, etc., have seized the opportunity to significantly develop compost production, building their first large compost production base and planting 8,200 hm2 in dekingong in 2007, yielding about 70,000 t. De qingheng county was awarded the title “kong jim village, china,” by the china economics and forestry association in 2004, and was also awarded the title “accreditation of products from the territory of origin of kung yi,” by the state quality monitoring authority in the same year; de qingung yu was awarded the title “chang quan quan qiang qiang qian and guangdong qian qiang products”. In june 2007, the “four concubines” were approved by the state trademark office as “the trademark of proof of origin”。
Conditions for cultivation
As recorded in the history books, as early as the first year of tang dynasty, the agriculture sector was well developed, mainly in the form of farming, and a large amount of it was grown in my district, particularly in the towns of maung, maung and xinang. It has been bred, bred and purified for generations by the hardworking people of deking. Unique geographical location, natural conditions, etc. Produce unique agricultural products. De jing is located in the north-west of the country, 180 km east of guangzhou, and in the west river of the famous “gold waterway” in the south, along the 321st and 325th lines of the national and provincial routes across the county, with easy surface and surface traffic, which is an important hub for communication and radiation in the greater south-west. De jing is at a low latitude with a mild climate, abundant heat, abundant rainfall, short periods of frost, south asia's tropical monsoon climate, with an average annual temperature of 22. 2°c (1997-2002), an average annual rainfall of 1513 mm and a concentration of rainfall in the months of april to september, accounting for 78. 4 per cent of the annual rainfall and an average of 1848 hours. De jing is a typical mountainous district, with a mountain water show, a three-faced north-east-west roundabout, and a river in the south-west, with a total area of 2258 square kilometres, of which 2. 62 million acres are mountainous and 210,000 acres are cultivated. Mountain and cropland soils are dominated by sandy soil, which, after long-term human-induced improvements, form a deep layer of soil, defusing air, preserving good water fertility, and having a rich organic content (1. 27-1. 94 per cent in drylands and more than 2 per cent in water fields), with a ph value of 4. 5 to 6. 5. Unique climatic and soil conditions are appropriate for the growth of the compost。
Plantation requires a park
Soils are required to be deep (60 cm), fertile; soil ph values are 5. 5-7. 0; orchard slopes are below 25 degrees. Parks should be planned with the necessary roads, drainage, water storage and ancillary construction facilities. When planning specifically, as far as possible, it should be centralized and built in good transport and water facilities。
Time
Usually planted after the autumn of september-november or before the spring of february-march。
Density
Cultivated with a density of 3 m x 4m, with 55-60 acres。
Plantation technology
Ground-drilling dens: stretching the line, digging the caves, deep and 80 cm wide, and then pressing back 50 cm green and 50 cm deep, filling the soil with 40 cm tall; field-drive planting: eight metres of cleavages (60 - 80 cm wide and 40 - 60 cm deep), 2 cm each (1. 5 m wide, 4 m centre, 20 - 30 cm tall). When planted, the roots of the tree are moderately trimmed and placed in the centre of the established den, the roots are stretched, the roots are stretched, the roots are set up, and they are slowly raised up and laid down on the edge of the soil, so that the roots are attached to the soil. Fill up the water with fixed roots, and make a 1 m plate around the tree seedling, covered with shells。
Soil management
Work should be done to deepen the dens, to fertilize the soil, to ban the planting of high-strength plants such as maize, wheat and so forth in the gardens, and to make the garden work rationally, and to plough and so on。
Fertilizer principles for water management
Blood orange needs for various nutrients should be adequately addressed by promoting increased application of organic fertilizers, rational application of inorganic fertilizers and formulation fertilizers. Fertilisation is also directed on the basis of leaf analysis, orchard soil analysis, compost waiting periods, etc。
Fertilisation methods
It is mainly soil-based and co-opts. Circumcisions, ditches, caves and soil fattening are used。
Fertilizing the larvae
In combination with the application of phosphorus, potassium fertilizer, five to six times during the spring, summer and autumn gestation periods (3, 5, 6, 7, 9 and december, 0. 4 kg of carbon ammonium or 0. 2 kg of urea per application). 1 - 3 years of larvae with pure nitrogen 100 - 400g, nitrogen, phosphorus and potassium ratio 1. 0 (0. 4 - 0. 5): 1. 0 appropriate. The adult tree has been fertilized four times, i. E. Precipitous, conservative, fertilizing and picking. Fertilizers are typically fertilizers of 2 to 3 kg and a load of manure; consumable fruit fertilizers of 1 to 2 kg of phosphorus + 1 kg of fertilizer; fertilizers of 1 to 2 kg of fertilizer of strong fertilizers + 1 to 2 kg of phosphorus fertilizers; and fertilisers of fertilizers (basic fertilisers) of 50 to 100 kg of organic + 1 to 2 kg of fertilizer, mainly organic fertilizers。
Water
Water is drained when the soil is dry. Orthopaedic cut, principle 1. It's local, it's tree trim, it's proximate, it's radiant, it's stereo。
Plastic
(naturally happy form) the main branches (three to four branches) are distributed by error, with the main poles divided by 30 to 50 degrees and the main branches having two to three branches. Usually, when the third branch is formed, the central category is to be trimmed to one side to the other to produce the branches。
Cut
(1) the larvae: the light cut. The extension of branches and branches of the main and sub-swire branches of the selected categories is followed by a medium or even shorter cut-off of the branches, and the balance between the branches is adjusted in the direction of short-cutness and cutting. Except for the appropriate omission of the shrouds, the inner-bore branches and the weaker branches of the tree canopy shall normally be retained. (2) initial results period: short-term treatment of long branches at all levels continues to be selected to wipe out summerfalls and promote healthy autumns. In the autumn, flower promotion measures such as circumculation, root breaking, water control and so forth were introduced for the waning trees. (3) sphinx period: timely retrenchment of branches, fallows and fallows, cut-off of branches, dead branches, insect branches。
Pests and pests against anthrax
Strengthen plant management to prevent the application of nitrogen-based fertilizers; before spring, summer sprouts and fruit ripening, the canopy can be used to spray tree crowns such as desen manganese zinc, copper pine acid, desen zinc, bacillus, etc., once for about 15 days and 3-4 consecutive times。
Feet decay
:: timely drainage, improved ventilation in the garden and improved control of tasting cattle and other tree-dry pests; selection of anti-disease logs, such as osteoporium, oranges and oranges, for the development of a sensory strain, which can be replaced with anti-disease logs. Medication prevention: post-scratching drug coating, common agent multibacterium, methyl tobuzin, etc。
Mites
(red orange spiders, four yellow spiders, rusted loice). Before and after the flowering (march-may) and in the autumn (september-november) are the focus periods for the fight against red spiders: pre-flower insects have a density of 1-2 head/leaf and 5-6 head/leaf after flowers and fall. The main periods of spring spasm, early fruit and fruit expansion are rust lice control: iron and stain on the back of the spring leaf in the same year; and instant control of the leaf or fruit infestation at concentrations of 2-3 head each. Commonly used agents are dicofone, dacarol, dicoft, brominated esters, amitraz, etc., with attention to the protection of natural enemies such as dictums, blunt mites, aphids, japanese acetal and grasshoppers。
Category
It's not a good idea. The focus period for drug control is the first generation of larvae, the high incidence of larvae (generally from mid-may to mid-june) and the prevalence of larvae. Common medicinal agents such as acetone, pyrophosphate, poxin + pyrochlor, losbane, oil emulsion etc. Pay attention to improving ventilation conditions in the garden; protect and use japanese natural enemies such as the headsace, red lips, grasshoppers, golden aphids, australian aphids and big red ladybugs。
Aphids
The rate of new victimization was 25 per cent and immediate spraying should be addressed. The usual medicines are tinker bell, lugo, dinskway, etc. Care should be taken to protect the herbs, herbs, aphids, aphids, bees, etc., and to cut off winter eggs and reduce the pest base。
Submarine moth
The focus of the response was on the summer and autumn seasons (early mid-july). The timely erasing of the small-spill summer fall, combined with the management of fatty water, has led to the development of new and robust strains. Medicinal control: spraying up to 1-2 cm, once for 7-10 days and 2-3 consecutive times. Commonly used medicines are avimectin (av), tragic dynamite (cdd), chlorocylene (ccp)。
Cows
In may-august, midday sunfalls of star and orange oxen became insects, while brown ox became insects at night; eggs were promptly cut off, larvae hatched and pellets were cut off; and insect holes were plugged with cotton or moistews, which were then closed with soil to poison the larvae。
Fleur maggots
The rheumatism is now distributed to the earth on the plate once every seven days, two or three times in a row, using finer soil, such as methaqualone, platinum and trichlorfon, when the diameter of the bud is 2-3 mm (now white), removing the victim's bud at an early stage and concentrating on deep burying or boiling; and during the winter season, deep-earthing of the soil can eliminate some of the winter pests。
Fruit harvest
The harvest period is determined by the maturity of citrus fruit, its use, market needs, etc. It is not appropriate to harvest fruit during rainy days and while the dew is not dry. The harvester shall wear gloves, cut the fruit with a round head cutter, then cut the crumbs, and then take it easy. The fruit is harvested from the outside and from the top to the bottom. All ferocious packagings are required to have smooth walls and harvested fruit should be transported to the packing or storage grounds in a timely manner. Avoid sun and rain。
Effects of different cooling temperatures on quality
Storage using 0, 4 and 8°c3 cooling temperatures to study nutritional indicators such as soluble solids, drip acid, total sugar and vitamin c content and changes in weightlessness and sensory evaluation. The congee is at three different refrigerated temperatures, showing generally the lower the nutritional indicator. The overall variation in soluble solids content ranges from 11. 4 to 13. 5 per cent; the dropble acid content rises from 0. 46 to 0. 60 to 0. 65 per cent; the total sugar content varies by the “s” type; and the trend in vitamin c changes is roughly the same. The lower the temperature, the lower the weightlessness rate, the better the senses. The combined analysis showed that 0°c cooled compost had a better effect, and that 4 and 8°c had a second effect. One
Effects of different concentrations of shell polygluting on the quality of storage
The study of the effects of different concentrations (0. 5 per cent, 1 per cent, 1. 5 per cent) of hull polysmelling coatings on the sensory evaluation, weight loss rate, vc, dripping acid, reduction sugar, soluble solid content, etc. ... The results show that 1 per cent of hull polysmelting can effectively slow down the reduction in weightlessness, maintaining a high sense rating and inhibiting vc, dripping acid, reduction sugar, soluble solids; after 21 days of storage, the conservation purpose was achieved by assessment, weight loss, vc content, drip acid content, reduction sugar content, soluble solids content of 6. 4 minutes, 5. 03 per cent, 13. 44 mg/100 g, 0. 31 g/100 g, 3. 36 g/100 g and 11. 95 per cent, respectively.
