Problems solved by technology

[0003] At present, the breeding and cultivation techniques of Phnom Penh hybrids are mainly based on cutting propagation and grafting propagation, but grafting is time-consuming and labor-intensive, and the sprouting of rootstocks greatly affects the growth and shaping of Phnom Penh hybrids. Plants are mostly propagated by cuttings
When cutting with conventional techniques, the survival rate of cutting seedlings is low (35.6%), and the rooting time is too long (about 2 months). prerequisites in landscaping

Embodiment 1

[0073] Select Phnom Penh hybrid S. chinensis, which is 1-1.5m in height, 3-4cm in ground diameter, robust in growth, free of diseases and insect pests, and of good quality, and is more than 4 years old as the mother plant. Collect semi-lignified branches as cuttings, the cuttings are 6-7cm long, keep 1 leaf, cut both ends into flat incisions, and the leaves are 0.5-1cm away from the upper end. Choose a 32-hole forest tree high-foot plug as a cutting container, add 2 / 3 hole sterilized substrate (deer marsh soil + vermiculite mixed at a volume ratio of 1:1), and then add 15g of arbuscular mycorrhizal fungal agent (inoculation potential ≥ 12,000 arbuscular mycorrhizal fungal agents prepared by rhizophagus intraradices (Rhizophagus intraradices, Ri) and Funneliformis mosseae (Fm) were mixed in a volume ratio of 3:1 ), add 2cm of sterilized matrix on the bacterial agent, pour water on the matrix in the plug tray; soak the spikes in 500 times liquid of 50% carbendazim wettable powde...

experiment example

[0077] On the 20th day after cutting, the cutting seedlings began to take root, on the 25th day, new leaves began to germinate, and on the 40th day, the rooting rate reached 87.5%.

[0078] Use the cutting propagation method that embodiment 1 provides to cuttage the method that the Phnom Penh hybrid Herba chinensis is compared with the method that comparative example 1 provides, take cutting 32 strains as example, specifically see Table 1:

[0079] Comparative example 1 Example 1 Initial rooting time (d) 35 20 Time for new leaves to germinate (d) 40 25 Rooting rate at 40d 45％ 87.5％ Survival rate 40.6％ 84.4％

[0080] Use the cuttage propagation method that embodiment 1 provides to cuttage the method for the Phnom Penh hybrid Herba chinensis compared with the conventional cuttage method, the 40th d rooting and new leaf germination situation after the cuttage, specifically see figure 1 .

[0081] Through the above comparison, using a...

Abstract

The invention provides a cutting propagation method for gold-edged hybrid elaeagnus pungens, and relates to the technical field of forestry planting. The cutting propagation method for the gold-edged hybrid elaeagnus pungens can significantly shorten the rooting time of cutting seedlings, improve the survival rate of the cutting seedlings, shorten the germination time of new leaves, therefore, the purpose of improving the cutting propagation efficiency of the gold-edge hybrid elaeagnus pungens is achieved, meanwhile, the problem that cutting propagation of the gold-edge hybrid elaeagnus pungens is difficult is solved, the plant propagation efficiency of the gold-edge hybrid elaeagnus pungens can be improved, and the cutting propagation method has great significance in large-area application and popularization of the excellent color-leaf shrub tree species.

Description

technical field [0001] The invention relates to the technical field of forestry planting, in particular to a method for cutting and propagating the Phnom Penh hybrid Scutellaria chinensis. Background technique [0002] Phnom Penh hybrid S. sativa is a plant of the genus S. sativa of the family S. sativa, which is widely used in landscaping. The Phnom Penh hybrid is an expanded tree with dense branches and leaves. The center of the leaves is dark green with yellow edges of different widths. It blooms in late autumn with silvery white flowers and a strong jasmine fragrance. It is of high ornamental value. This tree species has strong adaptability, can grow suitably in clay soil, loam soil, and sandy soil, and has the advantages of drought resistance and pruning resistance. It is a color-leaved shrub species with extremely broad application prospects. [0003] At present, the breeding and cultivation techniques of Phnom Penh hybrids are mainly based on cutting propagation and ...
