A kind of method for rapid propagation of hibiscus cuttings

Abstract

The invention relates to a hibiscus cuttage rapid propagation technology. According to the technical scheme, the technology includes the steps that firstly, a cuttage bed is built by using perlite as matrix; secondly, a humidity control system and an automatic spray system are constructed, a spray device is controlled according to change conditions of surface humidity of the matrix, and the rooting and growing environment of cutting slips is provide and adjusted; thirdly, strong and semi-ligneous or ligneous branches which are not damaged by pests or diseases and grown in the current year or yearly are selected as cuttings, and pruning and cuttage are carried out in time; fourthly, the branches are treated by using a rooting agent to hasten rooting before cuttage is carried out; fifthly, spray equipment is started and humidity parameters are set after cuttage is carried out, automatic spray is changed into manual control after 10 days, seedlings can be lifted 25 days after cottage, the seedlings are filled into a pot and subject to hardening-off, and the seedlings are transplanted 15 days later. The hibiscus cuttage rapid propagation technology is short in propagation period of nursery stocks, low in cost input and capable of being widely applied to large-scale and industrialized landscape nursery stock development for individuals and enterprises.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for rapid propagation of hibiscus cuttings. Background technique [0002] Hibiscus is a common landscaping tree species that is easy to survive from cuttings. In terms of breeding and raising seedlings, conventional field cuttings are often limited by factors such as season, environment and cutting operation process, and there is still a lot of room for improvement in important indicators such as rooting rate, survival rate, root system number, and reproductive cycle. [0003] The full-light spray cutting technology is a rapid propagation technology for seedling cuttings with relatively advanced technology and equipment. The equipment has a high degree of intelligent control and is very suitable for factory production. However, this technology also has some shortcomings in production. For example, its investment scale is large, and only the control syste...

Problems solved by technology

However, this technology also has some shortcomings in production. For example, its investment scale is large, and only the control system needs about 80,000 yuan; the temperature and humidity sensor is a highly sensitive electronic device, and the unit price is more than 10,000 yuan. It is extremely easy to be damaged and has a short service life, so it is difficult to buy matching substitute products in the market; there are special requirements for cuttings, and semi-lignified cuttings with 1-2 leaves must be selected, which inevitably wastes a lot of leafless cuttings; the rooting process Requires long-term spraying and requires a large amount of water

Because of this, this technology is difficult to meet the market's requirements for seedling cultivation with low cost, easy operation, and fast reproduction speed, and is rarely adopted by general large seedling farmers.

[0004] For some precious hibiscus fine varieties and edible varieties, due to the scarcity of resources and slow reproduction speed, the seedling breeding cycle is long, the cost is high, and the difficulty of popularization and application increases
