Problems solved by technology

However, 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 multiples, especially for some precious fine varieties. The lack of resources has led to delays in 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, preferably 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) Substrate preparation: use 30% pastoral soil plus 10% plant ash plus 20% perlite plus 40% rice husk (fermented) to mix as the substrate, and fill the substrate into the plug hole after fully mixing the components , the matrix should not be overfilled to facilitate the isolation of each insertion hole matrix, 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 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 rapid propagation technology of osmanthus fragrans micro-cuttage. Background technique [0002] Osmanthus fragrans is an excellent garden tree species that is closely combined with greening, beautification and fragrance, and has both viewing and use. It is also a traditional ornamental tree species in my country. For a long time, domestic and foreign scholars have carried out relatively extensive and infiltrating research on osmanthus fragrans. In recent years, a lot of research work has been done on the classification of osmanthus fragrans varieties, collection of germplasm resources, propagation and cultivation, harvesting and processing, and garden application. Great results have been achieved. However, the conventional cutting of osmanthus is limited by factors such as seasonal time, regional environmental differences and osmanthus growth speed, and has def...
