Regulation of new technologies of longan flowering Preliminary Study
Irrigation, pour the loss of more drugs, fewer irrigation contractors are not well soluble drugs, poor absorption of the tree. In this experiment 200 times the aqueous leaching facilities, the tree absorbs fast, healthy flowering ,35-4o days, it is clear to see 80% of the trees that have spikes. Required to promote Hua Guoyuan loose sandy loam soil, clay soil or years without plowing fruit orchards to teach poor dosage, this study did not set a different amount of testing but for r to ensure a good and flower effect, and also saving drugs to maximize input output rate, future screening tests through more optimal dosage. Tests showed that the best time to promote the flower,discount cosmetics mac, and flower in September to the end of November in general until after flowering, the winter low temperatures,mbt uk, the flowering time delay to next 1-2 months, and poor pollination,abercrombie fitch outlet, low fruit set, Fruitlet not good; June to promote the flower bloom is usually in August, due to high temperature, short flowering period, pollination is not very good, and found that there were burns and the formation of young fruit stiff fruit phenomenon. At the same time, we should consider the sound management of regulating production, reduce market pressure and increase efficiency. In addition, the success rate of flowering control when spraying fruit trees also, and phenology of the relevant,Tory Burch Shoes, has been observed when spraying fruit trees and leaf growth is in turn Jim Green of the best, this dance with the ratio of the carbon, catalytic oxidizer to be further studied Annual flowers can bloom longan fruit Zhang Hailan Wuding Yao (College of Horticulture, South China Agricultural University, Guangzhou 510642, China Xiao-Dong Lin) (School of Life Sciences, 1 oxidants reminder: fE of pass through status origin of longan in China is a typical subtropical evergreen fruit trees, and lychee , fruit trees such as citrus and olives, cold winter and drought are important conditions for flower induction. cultivars of longan in the physiological differentiation in late December to mid January flower bud differentiation, flowering period from late March to 5 months, the ripe fruit from south to north from June to late September. longan cultivated area of more than 530,000 hm2, longan in Guangdong Province, has grown to about 20 million hm2, fruit concentrated in the highest temperature of a summer half months of listing, the price of fresh fruit varieties with good storage Gaozhou is down in price from 20 yuan in 1989, k decreased to about 7 yuan year 2O00, b, as the country's longan production increases, prices still falling trend. In Taiwan, the fruit production practice and theory of regulation more effective, but also one step ahead of longan flower induction. They firecrackers within the gunpowder (potassium chlorate and sulfur as main components) treatment longan roots, leaching applied to the canopy in the trunk 314 position, after the leaching bearing casing. The results show that in different seasons, different places have different varieties of longan flower induction effect. even with the strains of some branches have fruit, nutrition can shoot bud differentiation (CR Yen et al, 1998). the end of 1998, some businessmen in Thailand and Taiwan signed a contract with some longan growers, hire secret orchard management, the purpose is the production of mature longan. main measures applied in the canopy leaching of potassium chlorate, potassium chlorate, or spraying the solution to the crown, the application to continue after commitment to plant irrigation. most treatments after applying tree 2o ~ 25 days will pumping light Zhou Xianjun Health spikes Yow Kam (, Xili, Shenzhen, Guangdong Province fruit market (Jungyco.uk, 1999). 1998 year, by technicians from Taiwan through various means Fujian, Guangdong and Guangxi longan farm cooperative, forcing the work carried out in Guangdong, the earlier application is some type of large longan Gaozhou field, such as high-City Baofeng lotus fruit market town, from the winter of 1998 started processing 10 longan , significant effect; November 1999 that longan processing plants to obtain 85% of the rate of flowering plants. longan fruit picking to be brought forward to May of around late in August 2000 to September Longan handled 50,000 , of about 90% of the flowering plant rate on November 23 to the site survey, most of the plants in the flower bud, flowering and fruiting period (Huangfeng Xin et al, 2000). Malaysia is located in tropical areas, the average annual temperature of 27 more fast-fast long longan tree has been planted as a green tree. longan in Taiwan since 1998, forcing the introduction of technology, the result after numerous longan trees. In the winter there is no drought, low temperature Malaysia, can now produce high-quality longan ( Data from Zhaoqing CST). In Taiwan, accidentally discovered after longan orchards burned firecrackers can promote flowering of longan, longan trees began to facilities forcing the country to test, so that longan flower induction technology has improved. if we can take seriously the subject, constantly sum up experience, and gradually master the longan flowering control technology, so you can adjust the large area of longan flowering planned to extend the annual fruit supply of, and innovation on the basis of conventional cultivation, in southern China will be resistant to the south of longan fruit industry and even a profound impact on industry.
