Blueberry Propagating And Cultivation Techniques In Zhejiang Province

Blue berry, also known as cranberry, blueberry, Vaccinium Ericaceae subfamily belong to the genus Vaccinium, a perennial deciduous or evergreen shrubs or small trees, mainly in North America and Europe, the 450 species in the world species. China has 91 of 28 known variants, both North and South distribution, but the main distribution area is the Southwest, North and Northeast China. Zhejiang, the geographical distribution of some, but the cultivated area is not large, the main still in the introduction and cultivation of the pilot phase, very few commercial cultivation.Blueberries have higher health care function, blueberries not only contains many fructose, fiber, vitamin A.C.E nutrition ingredient and so on, more important is rich in anti-oxidants, bacteria produce inhibitors, folic acid, quercetin chemical compounds such as flower pigments, these compounds for the elimination of free radicals in the human body, inhibit and reverse human aging has close relationship. For the elderly related diseases such as heart disease, arthritis, furrow etc have certain health care function and promoting the visual red element be synthesized, improve circulation, antiulcer, anti-inflammatory and so on many kinds of pharmacological activities, thus it can be seen, Blueberries is more than a fruit, more important is a kind of health care and functional food. So more and more places began planting blueberries, this leads to need a lot of seedling. Therefore, the research blueberry seedlings reproduction technology, to promote the blueberry expand planting and develop the rural economy has very big effect.This study through the different factors influencing the blueberry breeding and planting technology influence test, find out the best breeding methods and reasonable cultivation and management technology. Blueberries breeding method has a lot of kinds, different method has its own advantages and disadvantages, through experiment mastery appropriate reproduction method. Blueberries to environment is strict, must have certain low temperature and reasonable ph value, in long daylight conditions conducive to vegetative growth, and bud differentiation is required in DuanRiZhao conditions,20% of all sunshine intensity is the necessary condition of flower buds formation. So in different areas of the introduction cultivation, growing will have bigger difference. Therefore, through different areas of zhejiang introduction cultivation experiment, understand blueberries the most appropriate cultivation areas and reasonable cultivation techniques.Results show that blueberry can pass sowing, cutting, grafting and tissue culture technology for reproduction, cutting propagation operation technology is simple, but the cutting by cutting matrix, and survival rate of cutting time, cutting branches old tender degree and rooting cuttings factors such as the concentration of discretion agent is relative, through experiment obtains the best cuttings survived factor is cutting matrix requirements osteoporosis, breathable, organic matter content high, cutting time in 7-10 months best, cutting branches using half woodiness turn of green branches, rooting cuttings in commonly 750-agent concentration 1500mg/kg between the effect is good. Seed propagation method is simple, but the germination rate is not high, and there are varieties of tendency. To popularize than cutting seedling strong adaptability, but grafting methods operation technology is complex, and the survival rate is not high, with general stock uriah rice is good, and the tree branches connect better than the YaJie. Tissue culture technology although breeding quantity is more, but the breeding high technical requirements and breeding cost is higher. Therefore the current production on the commonly used method is cutting propagation. Blueberries in cultivation and management on soil properties of temperature and have special requirements, and the ability to 15 in temperature℃low temperature, general requirement winters are mild and summer temperature is higher, annual average temperature, in 18-22℃around. Soil organic matter content high, the requirements and nitrogen-fixing enough moisture and stable acidic sandy soil, especially for soil acidity condition especially strict, optimum pH value was 4.5-480. The water demand is not very strict, blue berries drought resistance and waterlogging-enduring sex belong to the medium. Therefore there are many places of zhejiang to grow blueberries, zhejiang development blueberry has huge potential.
