Rapid rooting cutting breeding method for sabina chinensis

Abstract

The invention discloses a rapid rooting cutting breeding method for sabina chinensis. The rapid rooting cutting breeding method includes the following steps that 1, cutting is carried out in September mid to October early every year, cutting roots are disinfected, regenerated roots are induced, then drying in the shade is carried out, and the product is covered with wet cloth for refreshing; 2, ridges are prepared in a greenhouse, the ridges are filled with cutting media, soil dwelling pests are killed, then disinfection is carried out, tilling is carried out, soil is completely watered with water, and covering is carried out with films; 3, cuttings prepared in the step 1 are inserted into the cutting media in the step 2, the temperature and the humidity are controlled, watering is carried out in a timing mode, cutting is carried out for 2 months, then watering is carried out one time every week, and 0.1% of monopotassium phosphate is sprayed for supplementing nutrients; 4, from the end of September to beginning of October of second year, the height of cutting seedlings reaches 20 cm at the moment, and the seedlings are transplanted. According to the rapid rooting cutting breeding method for the sabina chinensis, a bottleneck of cutting of the sabina chinensis in spring is removed, reproduction of the sabina chinensis is quickened, the rooting efficiency of the sabina chinensis is improved, the survival rate of reproduction is 98% or above, and reproduction plants of the sabina chinensis are increased by one time or above every year.

Description

technical field [0001] The invention relates to a plant propagation method, in particular to a rapid rooting cutting propagation method of cypress, belonging to the technical field of plant propagation. Background technique [0002] Cypress, a tree of the genus Juniper in the Cupressaceae family, is a cultivated variety of Juniper, with a height of up to 20m and a diameter at breast height of up to 3.5m. The bark is dark gray, longitudinally cracked, and cracked in strips; the branches of young trees usually extend obliquely, It forms a spire-shaped crown, and when it is old, the lower large branches are flattened, forming a wide round crown, the bark is gray-brown, longitudinally split, cracked into irregular thin slices and falls off; the branchlets are usually straight or slightly curved, and the branchlets with scales are nearly cylindrical Shaped or nearly quadrangular. When the dragon cypress grows to a certain height, the branches spiral upwards and grow like a drago...

Problems solved by technology

[0003] At present, the cutting propagation of cypress is generally carried out in spring, which limits the reproduction of cypress and cannot meet the current increasing consumption demand. In addition, Guizhou is prone to drought in spring. If cuttings are carried out when drought occurs, the cuttings will be affected. Wound healing, thereby affecting the survival rate of cutting propagation of Cypress
