Cuttage propagation method of elaeagnus pungens maculata

Abstract

The invention provides a cuttage propagation method of elaeagnus pungens maculata, and belongs to the technical field of plant propagation. The method comprises the following steps of (1) selecting a proper propagation place to establish an elaeagnus pungens maculata female parent cutting orchard; (2) filling a 72-cell plug with a substrate; (3) conducting cuttage once a year in early September which is a proper time for cuttage; (4) immersing cut branches with a root-promoting agent; (5) conducting cuttage by adopting the 72-cell plug; and (6) hardening seedlings after cuttage is conducted for 70 days and about 55 percent of cuttings are rooted. By adopting the cuttage propagation method of elaeagnus pungens maculata, the elaeagnus pungens maculata can be adaptive to the climate and soil conditions of China, has an excellent rooting situation, and has a yield of 85 percent; the cutting length is only 3-4cm, so that the utilization and propagation efficiency of female parent cuttings can be improved; and the method has strong adaptability, can be used in commercial large-scale production, has good repeatability, and has a good market prospect.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a method for cutting and propagating S. mosaicus. Background technique [0002] Elaeagnus pungens 'Maculata', an evergreen broad-leaved shrub, up to 4m high, with thorns, brown branchlets, covered with glandular scales, copper brown. Single leaves, alternate, leathery; dark green leaves, yellow to yellow-white at the margins, pointed, narrow and long oval, 4-10cm long, light green on the front, silvery white on the back, densely covered with silvery white or brown glandular scales; Flowers are silvery white, without petals, 1-4 clustered in leaf axils, flowering period is October-November; nuts, orange to pink, with silvery white markings, edible. It likes light, is slightly shade tolerant, likes high temperature and humidity, has strong adaptability to soil, and adapts to slightly acidic, neutral and slightly alkaline soils. Landscape use: flowers and lea...

Problems solved by technology

According to the existing literature reports, the research on the cutting propagation technology of S. sativa mostly focuses on the influence of substrate and hormone treatment on the rooting rate, while the technology of large-scale factory propagation of S. Management, production of commercial seedlings, etc. have not been reported

(2008) introduced the cultivation technique of Huluzi, the cutting time is carried out in the rainy season in June, and the cuttings are 10-15cm long, and 3-4 leaves are left on the upper part, which is a waste of cutting resources and reduces the reproduction rate. efficiency
