Problems solved by technology

[0003] At present, there are few studies on Japanese red maple Qinglong, and Japanese red maple cuttings are relatively difficult. Generally, Japanese red maple is propagated through grafting technology, but due to the affinity relationship between grafted rootstock and scion, the survival rate of grafting is about 70%, which eventually leads to grafting costs. higher

Embodiment 1

[0025] 1. Test material

[0026] The Japanese red maple green dragon begins to sprout and grow in March every year, and the green dragon branches grow about 20cm in May. The green dragon branches that grow during this period are used as test materials, cut off, moisturized, and set aside.

[0027] 2. Proportion of cutting substrate and substrate

[0028] Perlite: vermiculite: peat = 1:1:1 (mass ratio) mixed, set aside.

[0029] 3. Seedbed and cutting pretreatment

[0030] Seedbed specifications: 10 meters long, 1.2 meters wide, and 0.35 meters high. Spread a layer of gravel at the bottom of the seedbed with a thickness of 6cm-12cm. An automatic sprinkler irrigation system is equipped in the cutting shed, which is automatically sprinkled once every 15-30 minutes. In order to ensure uniform sprinkler irrigation, the sprinkler system adopts rotary sprinkler irrigation. Place one at a distance of 1 meter. The cutting shed is arched, with a plastic film attached to it. On sunn...

Abstract

The invention discloses a method for cutting propagation with tender branches of Japanese red maple Qinglong, wherein the method includes the steps of pre-treatment before cuttage, cuttage of Japanesered maple Qinglong, management after cuttage and the like. The treated Japanese red maple Qinglong has high rooting rate and developed root systems, and the operation is simple. Through the cuttage technology, hormone ratio and matrix screening, the cuttage of the Japanese red maple Qinglong is finally successful. Cuttage comprises the following steps: optimizing Qinglong tender branches grown incurrent year, quickly dipping in a preferable solution containing 500 ppm IBA and 300 ppm IAA, inserting into a mixed matrix with the ratio of perlite to vermiculite to peat of 1:1:1, spraying with water regularly to moisturize, and 30 d later, performing statistics on the rooting rate reaching 88%.

Description

technical field [0001] The invention relates to a cutting propagation method of Japanese red maple and green dragon twigs. Background technique [0002] Japanese red maple Qinglong is a small deciduous tree with a height of up to 8 meters. Although this variety has a beautiful leaf shape, it grows upright without drooping. The leaf color is light green in spring, bright green in summer, and turns to bright copper color in autumn, and there are not many scorched leaves in summer. The leaf palm is deeply divided almost to the base, and it is 7-11 deeply divided. The lobes are narrow and pinnate. Cleft, with finely toothed. Strong growth and fast growth, suitable for growing in North and South China. The new leaves of Japanese red maple Qinglong spit red in spring and summer, the leaves are bright and beautiful, and the old leaves turn green. It is an excellent new variety of foliage garden plants. The fiery charm of "Dancing Cuiyunjian" makes people intoxicated and contente...
