Problems solved by technology

Different from other types of Rhododendron species, which mainly adopt cuttings for propagation, it is difficult to take root from cuttings of Rhododendron japonica. According to existing research reports, the survival rate of cuttings of Rhododendron japonica is only about 50%; A lot of materials are used, and water management is complicated (Yang Hua, Song Xuzhong, Liu Xinhong, etc. A method for cutting and propagating S. chinensis: China, 201210007679.8 [P]. 2012.07.04.)

Embodiment 1

[0023] Provided is a method for growing seedlings by plugging green branches of Mayinhua, which specifically includes the following steps:

[0024] (1) Substrate preparation: mix perlite and vermiculite according to the volume ratio of 1:1, use a watering can to make perlite and vermiculite fully wet, mix well and put it into the seedling tray as cutting substrate , wherein the seedling tray is a 32-hole seedling tray, a water filter hole is provided at the bottom of the hole of the seedling tray, and the upper diameter, height and bottom diameter of the seedling tray are respectively 6cm , 9cm and 2cm.

[0025] (2) Selection of cuttings: on July 6, cut the semi-lignified twigs of the year as cuttings from the vigorously growing plants of Rhododendron japonica. The leaves on the twigs grow normally, and the diameter of the twigs is above 0.3cm;

[0026] (3) Cutting treatment: Cut the cuttings with a length of 8-12cm from the cuttings, keep the cuttings growth point and the up...

Abstract

The invention discloses a method for plug-tray greenwood cutting seedling culture of rhododendron ovatum. A semi-lignified twig grown in a current year is clipped and taken as a cutting, and a cuttingshoot is clipped from the cutting and soaked in an ABT reagent of concentration of 50-100 mg/L for 4-6 h; after soaking, the cutting shoot is inserted into a seedling culture plug tray for cutting, thorough watering is conducted immediately after cutting, a sterilizing agent is sprayed, and the seedling culture plug tray is coated with a thin film and shielded; and then, watering is conducted incase of dryness, and transplantation can be conducted when an axillary bud of the cutting shoot germinates and a new root of the cutting shoot grows to 1-3 cm. In this way, the method can greatly increase a cutting rooting rate of rhododendron ovatum, can increase a cutting survival rate of rhododendron ovatum to about 73.33%, can save a matrix and space of seedling culture, does not need establishment of a dedicated arc shed, realizes good moisture preservation effects, does not need frequent water supplementation, is simple and easy in operations, low in production cost and high in economicbenefits, can promote transplantation survival and has a high application value.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a method for raising seedlings by cutting and growing green shoots of the horse silver flower. Background technique [0002] Rhododendron ovatum (Rhododendron ovatum) is an evergreen shrub of Rhododendronaceae Rhododendron subgenus Rhododendron ovatum. It is a unique species in my country. It is mainly distributed in the shrubs below 1000m above sea level in the Yangtze River and Pearl River basins. Its flower colors are purple, lavender, pink and white. Large quantity, elegant color, light fragrance, high ornamental value. At the same time, Rhododendron japonica has the advantages of pruning resistance, strong branch sprouting ability, and pollution resistance. It is suitable for cultivation in urban parks, road greening, flower mirror flower beds, etc., and has broad prospects for research and development. However, no breakthrough has been made in the seedling propaga...
