A kind of hardening and acclimatization substrate of pinellia tissue cultured seedlings and its preparation and use method

Abstract

The invention relates to a pinellia ternate seedling tissue culturing, hardening and domesticating substrate and a preparation and use method for the same. The substrate is made from fine river sand, humus soil, perlite and composite vitamin B. The preparation method is that fine river sand and humus soil are screen and disinfected and then mixed with the perlite; at last the composite vitamin B is added. The use method is that when pinellia ternate tissue culture seedlings grow to 5 to 8cm, sterile water is sprayed and the seedlings are placed in a culture room for 2 to 3 days; then the seeds are taken out and roots are cleaned; the roots are immersed into 0.1mg / l naphthylacetic acid water solution for 10 seconds and then transplanted to the pinellia ternate seedling tissue culturing, hardening and domesticating substrate in a small shed with 40 to 60% of sunshade rate; the seedlings are hardened and domesticated for one month at the temperature of 40 to 25 DEG C and with humidity of 40 to 50%; and then the seedlings can be transplanted to fields. The raw material for the substrate can be easily accessed; raw material ratio is scientific and rational as well as effective; and domestic survival rate of the pinellia ternate seedlings can be improved by 96% or more.

Description

technical field [0001] The invention relates to a pinellia group substrate, in particular to a substrate for hardening and domesticating pinellia tissue culture seedlings and its preparation and use method. Background technique [0002] pinellia Pinellia ternata (Thunb.) Breit. is a plant of the genus Pinellia in the family Araceae. It is excavated in summer and autumn, and the dried tubers are used as medicine. It is an important traditional Chinese medicinal material and export material. Efficacy such as eliminating ruffian and resolving stagnation. For wet phlegm and cold phlegm, cough with dyspnea and excessive phlegm, phlegm-retention dizziness and palpitation, wind-phlegm dizziness, phlegm syncope headache, vomiting and regurgitation, fullness in the chest cavity, plum nucleus qi; external treatment of carbuncle, swollen phlegm nucleus and other diseases. From the beginning of the 1950s to the end of the 1960s, Pinellia pinellia was mainly used to excavate wild reso...

Problems solved by technology

Since the 1970s, with the gradual deepening of the research on the medicinal efficacy of pinellia, the market demand for pinellia has been increasing. The destructive mining of wild resources of pinellia has been far from meeting the market demand, resulting in the price of pinellia rising year after year. , Pinellia fakes are flooding the market

In order to solve the contradiction between supply and demand of pinellia, since the 1980s, we have started to explore wild varieties of pinellia and artificial cultivation techniques, and have accumulated rich experience. At present, the propagation of pinellia is mainly based on the asexual reproduction of tubers and bulbils. Mainly, but the amount of seeds used is large, and the reproduction coefficient is very low, the cost is also high, and the emergence rate of seed propagation is low, so it is not suitable for promotion in production

[0003] In order to improve the reproductive coefficient of Pinellia, adapt to the current standardized planting technical requirements, and lay the foundation for the research on the metabolic engineering of Pinellia, the use of tissue culture and rapid propagation to obtain Pinellia seedlings has received attention; How to obtain Pinellia tissue culture seedlings through explant screening, callus induction, detoxification treatment and other technologies, but there is no definite technology for the hardening and domestication of Pinellia tissue cultured seedlings; One of the technical bottlenecks of whether the tissue-cultured seedlings of Pinellia can enter transplanting and large-scale artificial planting

For the hardening and domestication of Pinellia tissue culture seedlings, there is no unified domestication substrate at present, and many of them are domesticated directly with a single sand base, but the effect is very poor and the survival rate is extremely low
