Description
Technical Field
The invention relates to the technical field of plant propagation, in particular to a factory seedling raising method for Chinese rose plants.
Background
The Chinese rose is evergreen or semi-evergreen shrub of Rosa of Rosaceae, is one of ten famous flowers in China, is also one of four cut flowers in the world, and has the reputation of "queen in flower". China rose blossoms in four seasons, has gorgeous flower colors, beautiful flower types, strong flower fragrance and long flowering period, and has higher ornamental value, use value and medicinal value (Zhang Jingpu, 2019). The Chinese rose cultivation has long history, strong adaptability to ecological environment and extremely wide cultivation range, is popular with people of all countries in the world, and has been widely applied to garden cultivation, flower cutting, pot culture and the like (Qian birch and the like, 2017; Zhang Fang and the like, 2019; Zhang Jingpu, 2019). In recent years, with the increasing level of urban construction, people have more and more demands on beautification and colorization of urban landscaping construction. China rose is increasingly favored in application and configuration of urban greenbelts as a woody ornamental flower with beautiful flower type, gorgeous flower color, rich flower fragrance and long flowering period, is gradually applied to urban roads, parks, river channels, residential areas and unit greenbelts in large quantities, and is well favored by citizens in urban beautification construction (qian birch and the like, 2017). In recent years, the use of Chinese roses as landscaping plants for elevated or isolated areas has become increasingly popular in the Yangtze triangle, for example, the use of Chinese roses in Hangzhou for road greening, elevated and overpass greening, wall and fence planting, flower bed planting, and construction of Chinese rose specialty gardens has significantly improved urban greening and human living environment quality (Qian birch et al, 2017).
With the increasing demand and usage, the cultivation and breeding technology of Chinese roses is also in urgent need of improvement. At present, the Chinese rose propagation method mainly comprises cuttage, grafting, layering, tissue culture and the like. At present, a cuttage method is mostly adopted for Chinese rose breeding, and compared with asexual propagation methods such as grafting and the like, the cuttage method has the advantages of fast propagation, regular emergence of seedlings, high survival rate and the like; compared with tissue culture propagation, the method has the advantages of low production cost, simple and convenient operation and the like; compared with sexual propagation such as sowing and the like, the method has the characteristics of retaining excellent properties of parents, short period, quick seedling culture and the like; therefore, the cuttage method is widely applied to production (Liu slim swallow, 2016) because of simplicity, feasibility, good property of the variety and short period. Although factors such as cutting slips, cutting matrix proportion, growth climate conditions, types and concentrations of plant growth regulators and the like in the cutting process of Chinese roses are optimized at home and abroad in recent years, and the cutting survival rate of the Chinese roses is obviously improved; however, the conventional Chinese rose cuttage has high labor cost and low seedling raising speed, still has certain limitation, and cannot achieve the effect of rapid propagation. With the increase of the production area of the worldwide Chinese roses, the international competition is increasingly intensified, the cultivation purpose of achieving high quality, high yield and low consumption is the trend of the development of the Chinese rose industry, the Chinese rose production system is developed to high technology, mechanization and industrialization, and the industrial seedling cultivation of plants is the main trend of Chinese rose breeding. The plant industrialized seedling culture adopts advanced seedling culture facilities and equipment, introduces a greenhouse intelligent control system, can remotely acquire air temperature and humidity, soil temperature, carbon dioxide concentration, illumination intensity and video images of a greenhouse environment, can automatically control equipment such as a greenhouse wet curtain fan, spraying drip irrigation, internal and external sunshade, a top window side window, heating and light supplement and the like, combines and applies an environment regulation and control technology, a fertilization and irrigation technology and an information management technology to seedling culture production seeds, and therefore large-scale production of seedlings is achieved. The plant industrialized seedling raising has the advantages of low production cost, higher mechanization degree and working efficiency, regular seedling emergence, less plant diseases and insect pests, no damage to the root system in the transplanting process of plug seedlings, high survival rate after planting, no need of seedling revival, suitability for long-distance transportation of seedlings, convenience for commercial supply and the like. The Chinese rose adopts an industrialized rapid breeding technology, can breed qualified commercial seedlings within 3-5 months, can completely retain various characters of parents, and has low breeding cost, large breeding coefficient and high breeding speed (Yan canula, etc., 2013).
The research on plant industrialized seedling is developed earlier in countries such as the netherlands, japan, and the usa, the plants have a mature industrialized cutting propagation technology, and the plants are put into practical production to produce a large amount of cutting seedlings in batches (mondskin apricots, 2008). The industrial seedling culture of plants in China starts relatively late, the industrial seedling culture is mainly focused on tomatoes, potatoes, cotton, melons and various vegetable crops at present, and the industrial cuttage breeding technology of plants of Chinese roses is still few. Although researchers at home and abroad have developed a large number of Chinese rose cuttage breeding tests to improve the Chinese rose cuttage rooting rate, the Chinese rose cuttage breeding technology cannot be timely applied to practice, and the industrial production level of plants in China has a certain gap compared with the international level.
The Chinese rose has rich cultural background, is one of five international industrialized flowers, is a typical representative of courtyard gardens, is one of ten flowers in China, has rich germplasm resources and a long cultivation history, and has high application value and commercial value and great market demand. In recent years, a novel production mode of China rose represented by factory, large-scale and intelligent production becomes a development trend of international China rose industry, particularly, the unit area output value of China rose seedlings is 3-4 times of that of traditional products at the beginning of a hot tide at home and abroad, and the novel production mode becomes a new development mode of flower industry. Therefore, the industrialized Chinese rose seedling breeding system is perfected from the aspects of plug selection, matrix matching, cutting selection, environment regulation (temperature, light and moisture), seedling storage and transportation and the like, the Chinese rose seedling quality can be improved, the annual supply of Chinese rose seedlings is ensured, and the market demand is met.
