Abstract

The invention discloses a cutting propagation method of aronia melanocarpa elliot. An ultrasonic humidifier is arranged in a three-dimensional seedbed; the moisture is preserved through coverage of a thin film and a non-woven fabric; perlite of 2-3 mm is filled into a 128-hole potted tray; from the early May to mid-October, branches are sampled from a female parent for cutting; the base parts of scions of the cutting branches are soaked by using 100 ml/L of Guoguang rooting powder; cutting is performed by using the seedbed; a management and maintenance stage is entered; when the rooting rate reaches about 95 percent, seedling acclimatization is performed. The method has the beneficial effects that the rooting situation is good, the yield can reach over 95 percent, the method has excellent market development prospect, the propagation operation is simple, the propagation speed is high, and the method can adapt to the climatic environments of East China and has a wide application range.

Example Embodiment

[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.
