A kind of container soilless culture technology of peony

Abstract

The invention relates to a peony container soil-free cultivation technology and belongs to the technical field of horticultural production. The cultivation technology comprises the steps that a prepared cultivation substrate is used as a basis, wherein grass peat and perlite are mixed according to the same volume ratio, then super high temperature overrotten peony special organic fertilizer, ternary compound-fertilizer containing N, P and K and 2,2-dimethyl-2,2-dihydrobenzofuranyl-7 n-methylcarbamate are added to the mixture, and the materials above are evenly mixed to form the cultivation substrate for using; special fertilization, nutrient solution watering or pesticide application is not needed for matched management technology, and simple weeding and watering are only needed. The peony container soil-free cultivation technology is simple and effective, convenient to operate, lower in cost and light to carry, efficient and standardized quantity production of container peony ornamental seedlings can be achieved, normal flowering for consecutive years in a container is guaranteed, and technical support is provided for peony flower regulation and garden establishment in different places or transplantation in the non-suitable transplanting period.

Description

technical field [0001] The invention belongs to the technical field of horticultural production, and relates to a container soilless cultivation process of peony. Background technique [0002] Peony is a traditional famous flower that is a special product of our country, and it is also a candidate national flower of China. Its flower color is gorgeous, the smell is fragrant, and it has high ornamental value, and is deeply loved by people at home and abroad. The traditional cultivation method of peony is ground planting, but there are problems such as immobilization and difficulty in flowering control. This cultivation method can't satisfy the demand of society to the industrialization of peony ornamental nursery stock and potted flower production. Container cultivation of peony has a long history, and it has been carried out in imitation of ground cultivation. Since the root system of peony is a fleshy root system, the root form of peony has undergone fundamental changes i...

The traditional cultivation method of peony is ground planting, but there are problems such as immobilization and difficulty in flowering control

This cultivation method cannot meet the needs of the society for the industrialization of peony ornamental seedlings and the production of potted flowers.

Container cultivation of peony has a long history, and it has been carried out in imitation of ground cultivation. Since the root system of peony is a fleshy root system, the root form of peony has undergone fundamental changes in fibrous roots after container cultivation. Limited, unreasonable substrate ratio for container cultivation of peony, resulting in bulky container cultivation, complicated management, and poor flowering quality, which limits the large-scale production of container cultivation peony

Although people have carried out extensive practice on the portability of peony container cultivation and achieved certain results, some key links of peony container cultivation have not been completely overcome so far, especially the research on the soilless and convenient peony container substrate has not been reported.

Wang Yan applied for "a nutrient solution for peony soilless potting and its preparation method and application". The core is to regularly water the prepared nutrient solution to provide nutrition for the growth of peony. The difficulty is that the frequency of watering, the quality and concentration of salt are not easy to control. The effect is not ideal; the "peony dwarfing potting method" applied by Wang Huafang et al., plants the peony plants in the potting substrate in the flower pot, uses the nutrient as the base fertilizer or topdressing to supply the plant nutrition, and waters the dwarfing agent and water, the actual operation It is also difficult to grasp; "a kind of lightweight substrate and preparation method for peony flower promotion" applied by Zhao Haijun and others, the substrate contains pine needle soil, ceramsite, vermiculite, perlite and fertilizer diammonium hydrogen phosphate, urea, zinc sulfate, sulfuric acid Potassium, copper sulfate, manganese sulfate, ferrous sulfate, boric acid, plant water-retaining agent, microbial pesticide, the composition is too complex and lacks operability

At present, the research on peony container substrates has not completely overcome the defects of container culture methods of peony, which are complicated, difficult to control and manage, poor flower quality, small amount of flowers, unable to bloom for many years, and difficult to expand and reproduce.
