Hydroponic breeding method of acorus gramineus

Abstract

The invention relates to a hydroponic breeding method of acorus gramineus. The method comprises the steps of (1) production of a hydroponic device, (2) preparation of propagule, and (3) cultivation ofthe propagule. The hydroponic breeding method of acorus gramineus has the advantages that the reproduction speed is quick, roots and seedlings grow strongly, the growth cycle of the acorus gramineusis greatly shortened, the phenomena of diseases and insect pests, yellowing of leaves and tip drying are further reduced, the quality of the acorus gramineus is effectively improved, and a scientificand effective way to realize standardization, scale and quality production is provided for the acorus gramineus.

Description

technical field [0001] The invention belongs to the field of papaya, in particular to a hydroponic breeding method of papaya. Background technique [0002] Qianpu, also known as Qianpu and Suishouxiang, belongs to the genus Iris of Araceae. It likes a warm and humid climate, and has a certain degree of cold resistance. It mostly grows in wetlands or rocks beside water below 1800 meters above sea level. Produced in Jiangsu, Zhejiang, Jiangxi, Hubei, Hunan, Guangdong, Guangxi, Shaanxi, Gansu, Sichuan, Guizhou, Yunnan and other places. The plant height is 10-20 cm, the branches are clustered, and the whole plant has a fragrance, which lasts long after touching it. The leaves are thin and dense, with long and narrow tops, no central ribs, and parallel veins; the upper part of the rhizomes is divided into clusters, the root system is distributed in a fan shape, and there are many fibrous roots; the rhizomes can be used as medicine. . It is suitable to be used as ground cover ...

AI Technical Summary

Problems solved by technology

Although the traditional soil culture breeding method can reach a maximum amplification factor of 7 times, the cultivation cycle is long, and only one cycle of division reproduction can be performed a year; it is prone to rice locusts, spider mites and other diseases and insect pests; limited by soil fertility, planting The density is low; the cost of daily maintenance is high; and it is greatly affected by external factors such as excessive application of fertilizers and soil pollution, and the yield and quality are unstable

Although there are a lot of exploratory experiments on the breeding method of P. chinensis, there is currently only one patent on the tissue culture of P. chinensis, that is, "a method of tissue culture and breeding of P. chinensis" applied by Su Yan et al. (patent application number 201710373879.8), the patent The tissue culture rapid propagation method adopted, in the experimental steps, the preparation of the medium, sterilization, sterilization of the explants, aseptic inoculation, primary generation, subculture and other processes must be carried out. There must be an autoclave, aseptic Special equipment and places such as inoculation room and tissue culture room have high technical requirements for experimental operators and are not easy to promote
