Cutting propagation cultivation method for Chinese junipers

Abstract

The invention discloses a cutting propagation cultivation method for Chinese junipers. The cutting propagation cultivation method includes the following steps that 1, yellow sand soil or humus soil with the pH value of 5-5.5 is used for a nursery land; 2, in the middle of March of the cuttage year, branches which are one or two years old and located on the upper middle portion of five-year-old Chinese junipers seed trees are cut and planted in a nursery bed in a cuttage mode with the row and plant spacing being 30 cm*30 cm; 3, a plastic film arch shed with the periphery sealed is arranged on the nursery bed with the cuttage branches after cottage, and when temperature is high in summer, a shading shed is arranged on the arch shed to cool the arch shed; on the one hundred and twentieth day after cuttage, when the rooting rate of the cutting branches reaches 90% or more, the plastic film arch shed is removed; 4, the cutting branches are cultivated in the nursery bed till the beginning of March in spring of the next year and then transplanted into pots. The propagation process of the method is simple and easy to implement, the survival rate of propagation cultivation is increased, the survival rate of transplanting bonsai forming is high, and propagation cost is effectively reduced.

Description

technical field [0001] The invention relates to a tree cutting propagation method, in particular to a juniper pine cutting propagation cultivation method, which belongs to the technical field of agricultural tree cultivation. Background technique [0002] Juniper pine, Juniper belongs to Cupressaceae, evergreen tree, distributed in the provinces and regions south of the Yangtze River, also called Juniper; Juniper bark is brown, longitudinally splits into long strips and flakes off; positive tree species, has certain shade tolerance; sex It likes cold and cool climates, and is much more cold-resistant than juniper. It has long taproots and well-developed lateral roots. It is not strict with the soil. It can grow in dry rock crevices and gravel in acidic soils and even at the seaside. It is an excellent landscaping tree species. , beautiful tree shape, green leaves, evergreen in winter and summer, reddish-brown or blue-black fruit, can be planted alone or in rows to form a spe...

Problems solved by technology

[0003] Because the seeds of juniper pine have the habit of sprouting every other year, and the seedlings propagated by seeds grow slowly, at present, cuttings are used for propagation, but the cutting propagation method of the prior art is complicated in process, and the survival rate of propagation and cultivation is low. The post-survival rate is not high, thus resulting in an increase in the cost of reproduction
