The method for culturing and transplanting seedlings of a kind of ecological remediation type Radix Glycyrrhizae
Technical field
The present invention relates to the seedling raising and transplanting of a kind of ecological remediation type plant, belong to field of plant growing technology, specifically the method for culturing and transplanting seedlings of a kind of ecological remediation type Radix Glycyrrhizae.
Background technology
Radix Glycyrrhizae (Radix Glycyrrhiza) has another name called state old, and lantern etc. are the pulse family herbaceos perennial, is a kind of help Chinese herbal medicine.Have and invigorate the spleen and benefit qi, clearing heat and detoxicating, expelling phlegm and arresting coughing, relieving spasm to stop pain, the effect of coordinating the drug actions of a prescription.Be applicable to weakness of the spleen and the stomach, lassitude hypodynamia, palpitation, coughing with a lot of sputum, the anxious pain of gastral cavity abdomen, four limbs contraction, carbuncle sore tumefacting virus, cushion toxicity, strong.Radix Glycyrrhizae also is widely used in food industry, refining candy, preserved fruit and chewing gum.Extract of licorice root is to make chocolate emulsifier, can also increase vinosity and the fragrance of beer, improves denseness and the colourity of dark beer, makes some soft drink and drinks sweet wine; The cigarette flavoring.Purposes is also extensively arranged in chemical industry, printing and dyeing industry.
China's Minqin County of Gansu cold summer heat, windy and dusty, few rainfall belongs to the continental monsoon climate in typical temperate zone; Vegetation coverage reduces, and evaporation increases and forms the saline land, so belong to damaged ecosystem.The degeneration of relevant impaired ecology and the research of ecological recovery attract wide attention; The research that China carries out the degeneration of damaged ecosystem and ecological recovery aspect also existing for many years, also need numerous scientific workers' unremitting effort and research and probe.
Radix Glycyrrhizae happiness arid climate, happiness sunlight is abundant, sunshine is long, and is cold-resistant, is grown in arid, semiarid desert steppe, desert edge and loess hill area more, fertility is strong, strong adaptability, strong stress resistance is in the Arid Desert Region performance effect of checking winds and fixing drifting sand, therefore the artificial planting Radix Glycyrrhizae not only has huge economic worth, has simultaneously the function that damaged ecosystem is repaired.
Summary of the invention
The present invention aims to provide the method for culturing and transplanting seedlings of a kind of ecological remediation type Radix Glycyrrhizae, the Radix Glycyrrhizae that produces with the method has solved the only defective of single cropping Radix Glycyrrhizae of traditional plantation Radix Glycyrrhizae pattern, the present invention utilizes the Radix Glycyrrhizae characteristic, its seed is placed in inducing culture, root media cultivation after treatment, then transplant in the land for growing field crops, thereby shortening greatly, the time that makes the plantation Radix Glycyrrhizae plays simultaneously the effect of checking winds and fixing drifting sand, not only bring economic benefit to planting peasant household, also have the restoration of the ecosystem effect, effectively solved simultaneously the saline land licorice planting difficult problem of keeping a full stand of seedings of emerging.
For achieving the above object, the method for culturing and transplanting seedlings of a kind of ecological remediation type Radix Glycyrrhizae of the present invention comprises production technology, field-transplanting, follow-up management that Radix Glycyrrhizae is grown seedlings, it is characterized in that:
One, transplant production technology: Radix Glycyrrhizae was rushed Xian 20~30 minutes with flowing water, then soak its surface 15~25min with 98% the concentrated sulfuric acid, then use 1% soaking with sodium hydroxide 12~30 minutes, aseptic water washing 8~10 minutes; To cultivate 20~30 days in the Glycyrrhiza Seeds access inducing culture that above-mentioned steps is processed, obtain the Radix Glycyrrhizae primary shoot; With the root induction in root media of transferring of Radix Glycyrrhizae primary shoot, cultivate and namely obtained the Radix Glycyrrhizae seedling in 30~45 days;
Described inducing culture is: add 0.5mg 6-benzyladenine, 0.02mg methyl α-naphthyl acetate, 0.3mg gibberellin, 2g activated carbon, 30g sucrose, 6g agar in every liter of MS minimal medium;
Root media is: add 1L distilled water, 1.0mg indolebutyric acid, 0.02mg methyl α-naphthyl acetate, 40g sucrose, 12g agar in every liter of MS minimal medium;
Two, field-transplanting: lifting: the Radix Glycyrrhizae seedling is used for transplanting at 10~15cm; Transplant: the Radix Glycyrrhizae seedling is played on the limit, and transplant on the limit, will use sufficient for the soil of Radix Glycyrrhizae transplanting base fertilizer, the leveling of rake a kind of farm tools, sprays the self-control blended, has sprayed overlay film immediately, presses 10cm * 20cm seeding row spacing and transplants, and pours water immediately after transplanting, and mu is kept a full stand of seedings and reached about 3.5 ten thousand strains;
Described self-control blended is: every mu of spray 0.37~0.38% Amex820 solution 21kg, 0.22~0.27% phoxim solution or trefanocide solution 14kg, 0.22~0.27% phoxim solution 14kg mix; Execute 40kg/ mu for every mu, vaporific spraying.
Three, follow-up management: after seedling moved, pouring water kept soil moisture content for topdressing then 2 times, imposes urea 10kg at every turn; Second and third year watered respectively water 3 times, and the last ten-days period in June, late October, dry year water a water in August; Second and third year once topdresses in conjunction with watering, and mu chases after urea 20kg, compound potassium sulfate fertilizer 20kg, compound potassium sulfate fertilizer 20kg, water for the first time ditch spread or spread fertilizer over the fields rake a kind of farm tools of the front combination of namely turning green.
The method for culturing and transplanting seedlings of a kind of ecological remediation type Radix Glycyrrhizae of the present invention, its beneficial effect is: Radix Glycyrrhizae is transplanted in desert restoration of the ecosystem band, has effectively protected the wild licorice resource, and has played the effect of checking winds and fixing drifting sand; Because the fertility of seed is strong, strong adaptability, strong stress resistance has reduced agricultural chemicals and the fertilizer application amount has improved the Radix Glycyrrhizae quality; Thereby, to compare with ecological reestablishment in the past, this kind method can be quicker, lasting forms desert soil to fix the sand structure; Radix Glycyrrhizae brings considerable economic results in society simultaneously, produces huge ecological environment benefit.
Embodiment
Embodiment 1
One, seedling growing process: Radix Glycyrrhizae was rushed Xian 30 minutes with flowing water, then soak its surperficial 15min with 98% the concentrated sulfuric acid, then use 1% soaking with sodium hydroxide 24 minutes, aseptic water washing 10 minutes; To cultivate 30 days in the Glycyrrhiza Seeds access inducing culture that above-mentioned steps is processed, obtain the Radix Glycyrrhizae primary shoot; With the root induction in root media of transferring of Radix Glycyrrhizae primary shoot, cultivate and namely obtained the Radix Glycyrrhizae seedling in 45 days;
