Method for cutting propagation of cynaroides king protea

Abstract

The invention discloses a method for cutting propagation of cynaroides king protea. The method comprises the following steps of: selecting a cynaroides king protea maternal plant, scissoring a twig from a position above a semi-lignified part as a cutting slip, and keeping 4 to 6 leaves; preparing a substrate by mixing peat and pearlite according to a volume ratio of 4:6, adjusting the ph value to be between 5.5 and 6.5 and the ec value less than 0.5; soaking the basal part of the cutting slip by using 1,000 ppm indole-3-butyric acid solution, and air-drying the basal part immediately after soaking 15 minutes; controlling the cutting depth to be 1 / 3 to 1 / 4 of the length of the cutting slip; and performing management according to a conventional technique after cutting, and performing field transplantation after seedling emergence. The application of the technique ensures that the survival rate of the cutting propagation of the cynaroides king protea reaches over 90 percent, and the propagation cycle is shortened to be 40 to 60 days. The obtained seedling is good in quality and has a long service life, and the offspring performance characteristics are stable and consistent, so a technical base for selecting and cultivating a new species with excellent characteristics is established. The method is simple and convenient, and has a low cost, a high seedling survival rate and a good market application prospect.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, relates to plant asexual reproduction technology, and in particular to a fast-propagating king emperor flower ( cynaroides King Protea) cutting method. Background technique [0002] The emperor flower is the dragon eye family ( Proteaceae ) Protea ( Protea ) evergreen shrubs. It likes a warm, slightly dry and sunny environment. It is not cold-resistant. The soil should be cool and watered. ℃. Protea ( Protea ) native to South Africa, there are more than 130 species and varieties, and king king flower ( Protea cynaroides King Protea) is one of the most well-known species and is the national flower of South Africa. The king's foliage is lush and the flowers are large. The flowers are actually a flower ball with many flower cores in the center and surrounded by huge, colorful bracts. The diameter of the curd is 12-30 cm. In a year, a large and strong plant can produce 6-10...

AI Technical Summary

Problems solved by technology

[0003]Protea cynaroides King (Protea cynaroides King Protea) is usually propagated by sowing, but the seedlings often mutate, resulting in the lack of excellent traits Maintenance, the poor consistency of the produced products restricts the large-scale commodity production and is not conducive to market sales

At the same time, imported seeds are expensive, and the seedling emergence rate is low, only about 40%, and it takes more than 3 years to flower, resulting in high production costs

Vegetative propagation techniques such as tissue culture and cuttings have been researched and tested at home and abroad, but there is no successful example at present

However, the survival rate of conventional cutting propagation technology is extremely low, only about 10%, and the rooting time required is as long as 1 year.
