Problems solved by technology

[0003] Safflower is widely used in gardens, and there are many reports about its cultivation and maintenance. Zhang Zhong (2006) reported the technology of cutting seedlings of Safflower twigs, but this method requires soaking the spikes in rooting powder 10-12h, time-consuming, not conducive to large-scale reproduction
Check the existing published patents and literature, there is no relevant report on the black pearl of safflower loropetalum

Embodiment Construction

[0039] Now, the present invention will be further described in conjunction with the embodiments of the present invention.

[0040] 1. Establishment and management of ear picking nursery

[0041] 1.1 Nursery

[0042] Select loose, fertile, slightly acidic, neutral to slightly alkaline land as the ear garden, plow, ditch, and make a bed, and open a deep ditch around the field. The bed surface of the seedbed is 120 cm wide, and the bed surface soil block The whole is thinner, slightly higher in the middle, and slightly lower on both sides; the trail is 40cm wide and 25cm deep, and the two ends of the trail are lower and the middle is slightly higher, forming a certain slope to ensure smooth drainage.

[0043] 1.2 Transplanting

[0044] Transplanting is carried out from early November to March of the following year. Design the configuration diagram according to the row spacing of plants, the row spacing of transplanted plants is 35cm×35cm, and the density is 3500 plants / mu. Di...

Abstract

The invention discloses a cutting propagation method for loropetalum chinense var.rubrum 'HZZ' and belongs to the technical field of plant propagation. The cutting propagation method comprises the following steps: firstly, selecting a proper breeding place to build a scion cutting orchard of loropetalum chinense var.rubrum 'HZZ' female parents; secondly, cutting by adopting a nursery bed; thirdly, selecting proper cutting time of the first ten days of March, the second ten days of June and the first ten days of September, and cutting scions, and performing three times in each year; fourthly, impregnating cutting branches by adopting a root promoting agent; fifthly, on the 30th day after cutting, starting to harden seedlings when about 95 percent of scion wood is rooted. The cutting propagation method for the loropetalum chinense var.rubrum 'HZZ', is simple in operation, high in propagation speed, good in repeatability, can be used for commercial scale production, is reported for the first time in China, and fills up the blank of related technical field in China; a finished product rate is as high as 95 percent.
