Research On Key Technology Of Fruit Tree Protected Cultivation

This article study on the the chilling requirement and the photosynthetic characteristics of apricot, peach, cherry, grape, plum in greenhouse; at the same time based on more than a decade of the cultivation test results of apricot, the development of its high-yield cultivation techniques regulation and Aimed at resolving the cultivation facilities in a timely manner Koupeng, fill light, to add carbon dioxide and other key and difficult problems, facilities for the cultivation of high-quality fruit trees to provide a scientific basis.Application hydroponic flowers, potted plants, and other test methods to determine the species of different species of natural end of the period of dormancy, and so on the basis, according to the model of 0-7.2℃, local weather data, measured 2 out of 12 varieties of tree species to be cold , The cherry the most chilling requirement for 1110-1280, followed by apricots, 860-910. It was all over the scientifically and reasonably determine the appropriate time Koupeng provided a basis.Systematically on the apricot, peach, cherry, plums, grapes and in the protection of the photosynthetic performance under the conditions studied. Determined to protect the fruit on the changes in the law, the application of gray correlation analysis to identify the impact of photosynthesis is the dominant factor stomatal conductance and transpiration rate, measured 5 out of 13 species and varieties of light carbon dioxide saturation point, compensation Point.Apricots saturation point of light in the 840^-1500μmol.m^-2.s^-1, light compensation point in the 40-110μmol.m^-2.s^-1 at present; the apricot CO₂saturation point in 1000-1600μl.l^-1 between , For more than 1200μl.l^-1; compensation point in the 60-90μl.l^-1 between.The grape light saturation point for the 840-1140μmol.m^-2.s^-1, light compensation point for the 175.9^-209.2μmol.m^-2.s^-1; grape CO₂saturation point for the 980-1515μl.l^-1, compensation Point for the 52-250μl.l^-1.Beautiful plum light saturation point, light compensation point of 1620,280μmol.m^-2.s^-1; red plum were 2000μmol.m^-2.s^-1 and 192μmol.m^-2.s^-1 Cherry's light saturation point for the 978^-1036μmol.m^-2.s^-1, light compensation point for the 40-200μmol.m^-2.s^-1; CO₂ saturation point for the 840-978μl.l^-1, compensation for the 24-point -39μl.l^-1.Lu early peach light saturation point and compensation point were 860μmol.m^-2.s^-1, 103.2μmol.m^-2.s^-1Technical regulations of apricot high-yield cultivation in Greenhouses is made, its include the protection of choice, facilities construction, building and park management, micro-environment-control and pest control technologies etl.. Standard has strong scientific and advanced, which detailed, comprehensive, guidance and operational standards laid down in the technical operation and easy-to-grasp, easy-to-promotion and application.
