Fast cultivation device of paridis rhizoma seedlings by natural energy and optimized cultivation method of paridis rhizoma seedlings

Abstract

The invention relates to a fast cultivation device of paridis rhizoma seedlings in the technical field of plant cultivation. Firstly, the paridis rhizoma seedlings are subjected to fast germination treatment, and then enter an environment control room for level one light auxiliary sound seedling period cultivation treatment in a room temperature environment, and then the level two light auxiliary fast cultivation treatment in a simulated outdoor environment is carried out in the environment control room before seedling damping-off in the first year. Based on a plant growth microenvironment control technology, by combining a sugarless culture micropropagation technology, under the premise that suitable environmental factors such as light, temperature, humidity, carbon dioxide, and nutritional elements are provided for the paridis rhizoma seedlings, the problems that the paridis rhizoma seedlings have a long germination period, fragile seedling growth, a low survival rate of transplanted plants, a long seedling period and the like are solved.

Description

technical field [0001] The invention relates to a device and method in the technical field of plant planting, in particular to a device for rapidly cultivating eucalyptus seedlings utilizing natural energy and an optimized cultivating method thereof. Background technique [0002] PARIDISRHIZOMA is the dry rhizome of Paris polyphylla Smith var. yunnanensis (Franch.) Hand.-Mazz. or Paris polyphylla Smith var. chinesesis (Franch) Hara of Liliaceae plant. Chonglou is an important raw material in the compatibility of Yunnan Baiyao and traditional Chinese medicine. Due to the long-term basic dependence on wild resources to maintain market demand, the natural resources of Zhonglou are extremely scarce, but the market demand is increasing year by year. However, the natural germination cycle of Chonglou seeds is long and the germination rate is low. It takes 2-3 years for seeds to germinate and become seedlings, and the rhizomes grow slowly. It takes 4-6 years from emergence to harv...

[0004] After searching the prior art, it is found that: Chinese Patent Document No. CN101248727, open date 20080827, records a kind of "artificial three-stage cultivation method for chrysalis", which includes primary seedling cultivation, secondary seedling cultivation, commodity There are three parts of Chonglou cultivation and field management, but the weight of the first-grade seedlings achieved by this technology after 3 years of cultivation only reaches "2 grams of rhizome weight", and it needs to go through two stages of first-grade seedlings and second-grade seedlings to achieve production For the cultivation of seedlings, at the same time, the primary seedlings and secondary seedlings of this technology need 3 years of cultivation period, and the time required to complete the seedling cultivation is 6 years, which is a long time

[0005] Chinese Patent Document No. CN101461327, publication date 20090624, records a kind of "Dian Chonglou rapid propagation technology and seedling hardening and planting method". The key to the survival rate of seedling planting is to use trace elements to harden the seedlings of Dianzhong, so that the survival rate of hardened seedlings can reach 80%, so as to ensure the survival rate of planting reaches 80%; hardening is to add vitamins and plant hormones to the regenerated seedlings After culturing in the culture medium, add trace elements to cultivate and then transplant; the planting method is to transplant the hardened seedlings in the sterilized formula soil culture bag, and when the newly grown terminal buds grow into leaves, It can be transplanted into the field and used for pest control. However, this technology is based on the plant tissue culture method of Chonglou to form seedlings. It is an asexual reproduction method with a multiplication factor of 5-6 times. Three batches of tissue culture seedlings can be cultivated within one year. Compared with common Plants such as gerbera (proliferation coefficient 14, culture cycle 30 days) have a much lower culture efficiency. Therefore, the actual number of seedlings depends on the number of explants collected, while the collection and detoxification of explants are not It is a job with a low success rate and high labor intensity. Skilled workers can usually handle no more than 100 explant samples per day. If large-scale production is required, large quantities of explant raw materials become the limitation of seedling production. factor
