Cutting propagation method of aronia melanocarpa elliot

[0011] A cutting propagation method of Sorbus serratus, first choose a multi-span greenhouse or a single greenhouse to build a sports seedbed. Use a 25mm diameter PVC to build a small arch on the three-dimensional seedbed. After installing an ultrasonic humidifier, cut off the branches One sprout is used for cuttings in 128-hole plugs filled with perlite, and 6 million cuttings are cut in a season in a single shed or multi-span greenhouse facility per acre. The perlite and the plugs are disinfected. It is suitable for early May to mid-October every year. Cutting time, cutting twice a year, and cutting ears from the female parent of the current year, the ears are with a bud and the length is 4.5-5.5cm, cut the 1.5-2.0cm needles of the lower part of the ear, and leave the upper part of the leaf Part 3.0-3.5cm, then immerse the base of the cuttings with 180-220ppm of Guoguang Rooting Plant Rooting Agent for 2-3 seconds. The main component of Guoguang Rooting Plant Rooting Agent is 20% naphthalene acetic acid, and 128-hole plugs are filled with pearls After the rock is fully watered, the cutting depth is 1.5-2.0cm. After the cutting is completed, spray a 1000 times solution of carbendazim and anthrax thiram mixture on the leaf surface, and the weight ratio of carbendazim to anthrax thiram is 4-7:4 -7, and moved to a three-dimensional seedbed in time, covered with non-woven fabric and plastic film, sealed around, thus entering the management and maintenance stage, immediately after cutting, use an ultrasonic humidifier to humidify, water every 3-4 days to make the substrate moisture content Reach 60-70%, the relative humidity of the air in the shed is above 99%, and the nutrient solution is poured every 5 days during the rooting period (EC is 1.0, pH is 6.5). Note that in summer, control the temperature in the shed below 35°C. When the temperature is too high, use a wet curtain fan or spray to cool down. Before rooting and germination, basically shading, shading rate of 75-90%, 55-65 days after cutting, when the rooting rate reaches about 95% To refine seedlings, first uncover the film at both ends of the arch for ventilation, and then uncover the non-woven fabric at both ends of the arch for ventilation after 3-5 days. After 3 days, remove all the films for full light exercise. The nitric acid in the nutrient solution is 950mg/L. Potassium nitrate is 810mg/L, magnesium sulfate is 500mg/L, dihydrogen ammonium phosphate is 155mg/L, EDTA iron sodium salt is 15-25mg/L, boric acid is 3mg/L, manganese sulfate is 2mg/L, zinc sulfate is 0.22mg/L, copper sulfate 0.05mg/L, ammonium molybdate 0.02mg/L. The beneficial effects of the invention: the invention has good rooting conditions, so that the yield can reach more than 95%, and has a good market development prospect; the invention has simple breeding operations, fast reproduction speed, and can adapt to the climate environment of East my country in the scope of adaptation wide.
