Jujube seedlings for the Northwest Territories

Jujube industry is based on natural resources in Northwest China and production conditions, highlighting regional characteristics and quality advantages to develop new industries. Northwest is located in China's inland, is a typical continental monsoon climate, drought and extremely uneven spatial and temporal distribution of precipitation, crop production and other sustainable and stable development is extremely unfavorable. Dates have drought, cold, poor resistance, resistance to sand characteristics, especially with a budding jujube seedlings of late, long flowering period of superiority, be able to escape the storm and regularity Northwest cool weather, so the northwest region is growing dates The area is relatively good. First, Guoguang jujube: jujube-oriented center Guoguang find rare local varieties bred, good traits through years of cultivation experiment, and domestic and foreign names, observe the contrast excellent jujube, jujube Guoguang demonstrated by the other jujube can not go beyond, it has the following salient features: fruit tree seedlings green seedlings seedlings seedlings seedlings of fruit trees 1, large fruit, excellent quality: fruit weight 30-50 grams, 98 grams largest fruit oval, purple, fruit smooth surface slippery bright, colorful, form, color both the United States, outstanding, large fruit, but a very small core, outer core phenomenon seedless, tender meat, crisp and refreshing, juicy no residue, concentrated sweet sour, delicious taste. Containing soluble round was 36.8 percent, sugar 25%, acid 0.44%, graceful style, excellent quality, in fact, the fruit of treasures. 2, good ripening season: Now, most are concentrated jujube varieties available in early August to mid-September, while the country ripe jujube light at the end of September early October, it listed a large number of neutral jujube mature, and mature season coincided with the Mid-Autumn Day two festivals, the market demand and expensive. 3, early fruit is strong, very high yield: When planting fruition, then both grafted seedlings in a nursery more than 60% of the seedlings bear fruit, fruit period of three years backward, the highest yield of up to 3000 kg, the yield Sheng like surprising. And year after year high and stable yield, no size of the points, in terms of its production, in all varieties of jujube, jujube topped Guoguang. 4, crack resistance, not preharvest fruit drop: Most jujube varieties, especially the most fresh-shaped jujube varieties, in case of rain before maturity easy cracking, but it never happened Guoguang jujube fruit cracking phenomenon, showing a very strong crack resistance. Mature 10-20 days after harvest can be delayed in the trees, preharvest fruit drop light. 5, adaptable, extensive management: logging, ground water could grow three to three months, drought-resistant, Low (but in fertile ground, grow faster and yield higher). Extensive management, flowering and fruiting, yield year after year, fruit very good storage, the development of two large area, Zhanhuadongzao: Zhanhuadongzao is a mature late, rare fresh fruit, at 0 ℃ ~ 5 ℃ in conditions can be stored for 4 months, to supply the market in the off-season fruit, especially to supply the market in the New Year and Spring Festival. Currently, the market in Beijing, Shanghai, Guangzhou and Hong Kong SAR, Zhanhuadongzao priced three times higher than dry dates. Because jujube jujube yield is higher than dry more than doubled, so now Zhanhuadongzao 6 times higher than the economic value of Watkins jujube and other dried jujube varieties, but the former market selling, the latter unmarketable. Meanwhile, Zhanhuadongzao is the fruit of a new resource, after enter the international market has broad prospects. Zhanhuadongzao produced in the Bohai Sea in Shandong Province, the Yellow River Delta, it is a late maturity, rare fresh fruit. Zhanhuadongzao Fruit nearly round, average weight 14.6 grams, fruit surface smooth, thin skin, ocher red, shiny, white flesh, crisp and tender and juicy, taste food no residue, sweet fragrance, nutrient-rich. Zhanhuadongzao fruit is round, like apples, the "Little Apple," said Zhanhuadongzao nutritious, containing 19 kinds of essential amino acids aspartic acid, threonine, serine, etc., especially vitamin C content is 70 times that of Apple's, 140 times the pears, known as "living vitamin pill." In addition, Zhanhuadongzao also contains more trace elements vitamin A, vitamin E and potassium, iron, copper, etc., have anti-cancer effects, the nutritional value of mince. Prof. Agriculture Horticulture American Institute of Biological Sciences Oregon State University in Bowie Seoul after tasting Zhanhuadongzao called "the world's first fruit." Zhanhuadongzao although there is a strong adaptability, but is particularly fond of the soil more fertile, high organic matter content of loam or sandy loam soil in such growth Zhanhuadongzao tall crown, deep roots and broad, high yield, good quality . Zhanhuadongzao and other jujube as temperate deciduous fruit trees, their growth and development require a higher temperature, so the budding late, leaves early. Third, the large Xuezao: Big Xuezao found in the Yimeng Mountain, Great Xuezao is a large, special late-maturing, high-quality, precious and rare local varieties, cultivated by years of observation, Great Xuezao mainly has the following characteristics: 1, a large fruit beautiful appearance, good quality fruit: fruit weight 52g, maximum l18g, a large canning jars can only be installed under the two largest jujube, breaking the record of the date fruit weight history. Fruit flat round, slightly flat at both ends, the appearance of purple, white flesh, flesh nuclear small, edible rate of 97.3%, tender meat, crisp, refreshing fragrance 35% soluble solids, sugar 73.6% dried dates, very good storage, superior quality. 2, early fruit is strong, very high yield: Great Xuezao general then planted, when the results of two years of bumper crop, the third annual yield of up to 2000kg or more (2 m × 3 m spacing), full fruit generally up more than 3000kg , very high yield. 3, adaptability, water logging, drought-resistant: sandy soil, clay soil, black soil, loess, saline-alkali soil, south acid soil, Qingshishan, sand mountains are suitable for planting large Xuezao, which is resistant to drought, half a year it does not rain, without water you can still get a good harvest; ditches, ground water two months, no waterlogging, does not affect the yield, showing strong adaptability. But in the fertile soil planting, to strengthen soil water management, good fruit color is beautiful, quality, higher yields. 4, especially late, good ripe season: big Xuezao in Yimeng Mountain, by the end of October to 11 early maturity, the maturity date on all the latest, is a very late-maturing varieties, positive off-season fruit on the market, the market is expensive. 5, high economic efficiency, high export potential: large Xuezao nutritious, rich in vitamins, amino acids. The vitamin C is 100 times Apple's nutritional value is particularly high. In recent years sales of wholesale price per kilogram in the city between 40 to 70 yuan, the price steady rise, with China's accession to WTO, as China's unique jujube fruit, is out of the country for growers with a greater economic benefits.
