Abstract
The invention discloses a plantation method for obtaining high-content high-yield sweet wormwood in saline-alkali soil. The plantation method comprises preprocessing seeds, sorting land, raising seedlings, transplanting and harvesting. Compared with the prior art, the method has the advantages that sweet wormwood seeds are soaked in a salt solution and processed by microwaves, and the resistance of the seeds is improved; by turning over soil and building a drainage system, the salinity of the saline-alkali soil is reduced and the accumulation of salt in the surface soil is prevented; by raising the seedlings and transplanting in advance, the growth period of the sweet wormwood is prolonged, the sweet wormwood is harvested before blower buds appear, and the artemisine content is ensured; and therefore, the high-content high-yield sweet wormwood is obtained in the saline-alkali soil which is not suitable for growing the sweet wormwood originally.
Description
Technical field
The present invention relates to the agricultural planting technique field, be specifically related to a kind of kind method for planting that obtains high-load high yield sweet wormwood in the saline land.
Background technology
Sweet wormwood is China's traditional Chinese medicine, and effect clearing heat and detoxicating, soothing liver-gallbladder is arranged, and in Ge Hong " Handbook of Prescriptions for Emergencies ", can be used for treating malaria with regard to sweet wormwood on the books.The seventies in last century, China scientist separates the acquisition qinghaosu from sweet wormwood, and qinghaosu and derivative thereof have become a line medication of current treatment malaria, concern hundreds of millions of malaria patients' life and health.
Because the qinghaosu complex structure, chemosynthesis is with high costs, and main source still extracts from the plant sweet wormwood.All there is distribution on many ground, the wild sweet wormwood whole nation, but have only the sweet wormwood content in area, Wulin tomb mountain range higher, possess the industry extraction and are worth.Along with the increase of the whole world to the qinghaosu demand, wild sweet wormwood can not satisfy current demand.Current have only Chongqing, Hunan etc. sporadicly to plant along the peasant household in Wulin tomb mountain range area, but be subject to the condition in mountain region, standardized planting on a large scale, and quality, quantity is instability all, a little less than market risk withstand force.
The sweet wormwood plantation of development scaleization is the inevitable choice that solves the qinghaosu raw material sources, but China's arable area is limited, is guaranteeing under the prerequisite of grain-production, and the soil that the existing suitable crops of very difficult searching large tracts of land are cultivated is used for the sweet wormwood plantation.There are large-area beach ground and landlocked saline land in China, because the salt alkali content is high, and unsuitable common crop growth, availability is very low, and economic benefit is very poor.If can utilize saline land plantation sweet wormwood, can not only solve sweet wormwood plantation problems of land utilization, create higher economic benefit, and can improve the soil, bring more land under cultivation, produce multiple benefit.But existing sweet wormwood kind and planting technology only are adapted to the geographical climate environment on Wulin tomb mountain range, transplant in other areas, will produce qualitative variation, the phenomenon that output content significantly reduces.
Summary of the invention
The objective of the invention is to overcome the deficiency that above-mentioned prior art exists, a kind of sweet wormwood kind method for planting of the acquisition high-load high yield that (comprises beach ground and landlocked saline land) in the saline land is provided.
The objective of the invention is to realize through following technical scheme:
The present invention relates to a kind of kind method for planting that obtains high-load high yield sweet wormwood in the saline land, comprise the steps: seed preliminary treatment, consolidation, grow seedlings, transplant and gather in.
Preferably, said seed preliminary treatment is that used salt solution soaking seeds of southernwood or applied microwave are handled seeds of southernwood.
Preferably, said salting liquid is that sodium chloride solution, sodium bicarbonate solution or mass ratio are the sodium chloride of 1:1 and the mixed solution of sodium bicarbonate.
Preferably, the concentration of said sodium chloride solution, sodium bicarbonate solution, mixed solution is 50mmol/L～500mmol/L; The time of said immersion seeds of southernwood is 12～24 hours.
Preferably, during said microwave treatment seeds of southernwood, microwave power is 50～200W, and the processing time is 2～10 seconds, and number of processes is 1～3 time.
Preferably, said consolidation comprises turning over of soil and building of drainage system.
Preferably, turning over of said soil is specially: at the real tillage in the first year of plantation, ploughing depth is 0.15～0.3 meter; In the said drainage system, the degree of depth in drain ditch is 0.3～0.8 meter, and wide is 0.3～0.6 meter, is spaced apart 5～10 meters.
Preferably, said growing seedlings is specially: select loose soil as the seedbed, at sowing in the 1～February in every year, plastic mulching heat and moisture preserving; The seedling spacing is 2～5 centimetres, seedling raise period 2～3 months.
Preferably, said transplanting is specially: transplanting time is 4～May, and spacing in the rows is 60 * 60 centimeters～100 * 100 centimeters.
Preferably, said harvesting is specially: in 8～September, buddingged preceding 3～15 days apart from sweet wormwood, adopt manual work or mechanical mode that sweet wormwood is cut down, dry in the shade or dry collection sweet wormwood cured leaf.
Compared with prior art, the present invention has following beneficial effect:
The present invention is through the pretreatment mode of seed; Be that salting liquid soaks or microwave treatment can strengthen seed resistance; Improve its sprouting characteristic in the saline land and the salt tolerant alkalescence of seedling; Growing seedlings in advance helps sweet wormwood further to adapt to the saline land, and suitable temperature and humidity helps the germination of sweet wormwood, and the suitable spacing and the growth time of prolongation help the health of seedling and healthy and strong.Through the soil construction with drainage system of turning over, help utilizing natural rainfall to fill the pouring soil salt, reduce saline and alkaline, prevent the accumulation of salt in the surface soil.Before the existing bud of sweet wormwood, gather in, help the abundant accumulation of qinghaosu, prevent again that existing bud rear blade from dwindling and cause the underproduction, and the qinghaosu degraded.Through the above mode that is different from the tradition plantation, the guarantee sweet wormwood is grown normally, obtains high-load and high yield sweet wormwood cured leaf.
