Problems solved by technology

[0002] The conventional cutting of osmanthus is limited by factors such as seasonal time, regional environmental differences and osmanthus growth speed, and has defects such as slow rooting, slow growth, long propagation cycle and low propagation multiple, especially for some precious varieties, due to the source Scarcity and delayed promotion

Embodiment Construction

[0013] (1) Preparation of the container: choose a 4*4*4.5cm hard plastic tray as the matrix container. In order to facilitate the control of temperature and humidity, the entire hole should not be too large, at 1000-1500cm 2 within. Fix 6 support rods around the hole plate to facilitate film covering after cutting. The support rods are 10 cm long, and the top 5 mm is bent into 90° to prevent the film from being punctured.

[0014] (2) Preparation of matrix: use 30% pastoral soil plus 10% plant ash plus 20% perlite plus 40% fermented rice husk to mix as the matrix, and after fully mixing the components, fill the matrix into the plug hole. The matrix should not be overfilled so as to facilitate the isolation of the matrix of each insertion hole, thereby preventing mutual infection of germs through the matrix. Finally, pour it with 0.1% carbendazim solution.

[0015] (3) Pretreatment of cuttings: select the lignified sweet-scented osmanthus branches of the year as the cuttings...

Abstract

The invention belongs to the agricultural technology field, and particularly relates to a micro-cuttage and rapid-propagation technology of sweet-scented osmanthus. The micro-cuttage and rapid-propagation technology includes: selecting a plug tray of 40*40*45mm as a matrix vessel and constructing a support of covering films on the plug tray; mixing 30% of field and garden soil, 20% of plant ash, 20% of perlite and 30% of rice hull, using the mixture as a matrix, and disinfecting the matrix; selecting annual and lignified sweet-scented osmanthus branches as cuttings to be performed cuttage, and shearing the cuttings into small sections according to knot intervals, wherein each section is provided with only one bud knot and two leaves; cleaning and disinfecting the cuttings, and inserting the cuttings into the plug tray after performing glue enveloping on a section wound on each cutting; dropping growth hormone into each transplanting hole; sealing and moisturizing the plug tray. The micro-cuttage and rapid-propagation technology of the sweet-scented osmanthus greatly increases an expanding propagation multiple of cuttage propagation of the sweet-scented osmanthus by shortening the cuttings, enables survival rate of the cuttings to reach above 95% by improving the matrix of the plug tray and performing pretreatment before cuttage, and enables the rooting percentage of the cuttings to reach above 80% during one month by controlling temperature and humidity and processing the cuttings with the growth hormone.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for rapid propagation of sweet-scented osmanthus by microcutting. Background technique [0002] The conventional cutting of osmanthus is limited by factors such as seasonal time, regional environmental differences and osmanthus growth speed, and has defects such as slow rooting, slow growth, long propagation cycle and low multiplication factor, especially for some precious fine varieties, due to the source Scarcity has led to delays in promotion. In the present invention, the osmanthus cuttages are freed from the restriction of the land conditions by using the plugs as an independent seedbed, and can be cultivated and raised seedlings anytime and anywhere. At the same time, due to the relative isolation between the insertion holes of the plugs, the spread of diseases and insect pests is also greatly limited; The length of the cuttings reduces the number ...
