Background technology
Radix Angelicae Sinensis [
angelica sinensis(Oliv.) Diels.] be the Umbelliferae archangel, the another name Qin is returned, Min returns, China's parts of generic medicinal plants have the title of " ten side's rules for doing division with a one-digit divisor on the abacus ", have enrich blood, invigorate blood circulation, the effects such as menstruation regulating, pain relieving, ease constipation.The Radix Angelicae Sinensis main product in Gansu, the province such as Yunnan, Sichuan, Shaanxi, Qinghai, the Angelica Sinensis area under cultivation accounts for the whole nation more than 75%, accounts for domestic market more than 85%, and export trade accounts for national Radix Angelicae Sinensis export volume more than 90%, Angelica Sinensis with Minxian County, Gansu the best, has the title in " township of Chinese Radix Angelicae Sinensis " especially.The conventional production cycle of Angelica Sinensis is 3 years, the 1st year 6-7 month seeding and seedling raising, and late October is dug the seedling storage, the 2nd year 3-4 month transplant planting, gather in the crops fleshy root autumn and do medicinally, and within the 3rd year, the maternal plant bolting of reserving seed for planting blossoms and bears fruit, the results seed, if the 2nd year bolting is called Early bolting.
At present, the Radix Angelicae Sinensis more options of growing seedlings are opened up wasteland and are grown seedlings on the mountain region of height above sea level 2400~2800m.Opening up wasteland two kinds of virgin land and abandoned lands though this seedling raising manners has, is all to select Schattenseite ground, edge, forest zone, strikes off shrub, cuts off weeds, after burning the grass on waste land, turning over, does drill seeding kind.This seedling raising manners not only heavy damage ecotope, and be difficult to control because the impact that is subject to climatic environment makes seedling size, cause Radix Angelicae Sinensis Early bolting rate high.Investigation shows: general Chinese Angelica Field Early bolting rate is 20%~30%, and when serious, up to 60%~80%, the angelica root pollard materialization after bolting, lose medical value, to peasant's production and income, brings great loss.
Extend Radix Angelicae Sinensis vegetative period by the winter greenhouse seedling growing process, become life in 2 years into annual, avoid seedling can solve the difficult problem of Radix Angelicae Sinensis Early bolting by low temperature vernalization seedling stage.The main transplanting of Solar Greenhouse in Winter feeding block seedlings raising carrying substrates, the seedbed seedling raising and transplanting etc. of nursing young plants in hothouses of adopting, but the nutritive cube carrying substrates is transplanted many employing soil or organic matter is seedling medium, carrying is inconvenient, the amount of labour used is large, and root-naked transplanting is due to Radix Angelicae Sinensis seedling tool meat taproot, directly transplanting can cause offspring to proceed to resting state impact growth, cause the root-naked transplanting survival rate low, transplanting seedling time is long.Existing Radix Angelicae Sinensis greenhouse transplantation of seedlings all only adopts the gibberellin breaking dormancy, although there is certain short root to delay the seedling effect, but due to the defect of himself, cause and transplant that Radix Angelicae Sinensis transplantation of seedlings survival rate is not high and seedling-slowing stage is long, because gibberellin has the effect that promotes flower bud differentiation, cause the Early bolting rate to rise simultaneously.Therefore, seek and a kind ofly can break the Radix Angelicae Sinensis root-naked transplanting dormancy of nursing young plants in hothouses and improve survival rate and shorten conditioning agent that seedling-slowing stage can reduce again the Early bolting rate the nurse young plants in hothouses popularization of root-naked transplanting technology has great importance to Radix Angelicae Sinensis.
Summary of the invention
Purpose of the present invention is exactly for above-mentioned defect of the prior art, do not provide can damage to the Radix Angelicae Sinensis seedling, easy to use, promote root system to occur, improve the root-naked transplanting survival rate, shorten the slow seedling agent of the short root of Radix Angelicae Sinensis root-naked transplanting of seedling-slowing stage.
To achieve these goals, technical scheme provided by the invention is: the slow seedling agent of the short root of root-naked transplanting of nursing young plants in hothouses of a kind of Radix Angelicae Sinensis, add the following following material according to weighing scale in every 100kg water: gibberellin 0.1-1.0g, compound sodium nitrophenolate 0.2-0.8g, diethyl aminoethyl hexanoate (DA-6) 0.1-1.0g, indolebutyric acid 0-0.2g, methyl α-naphthyl acetate 0-0.4g.
Second purpose of the present invention has been to provide the nurse young plants in hothouses preparation method of the slow seedling agent of the short root of root-naked transplanting of above-mentioned a kind of Radix Angelicae Sinensis, comprises the following steps:
1) methyl α-naphthyl acetate of the gibberellin of 0.1-1.0g and 0-0.4g is placed in to the 5-10ml absolute ethyl alcohol and dissolves, obtain mixture one;
2) compound sodium nitrophenolate 0.2-0.8g, diethyl aminoethyl hexanoate (DA-6) 0.1-1.0g and indolebutyric acid 0-0.2g are placed in to 100kg water and dissolve, obtain mixture two;
3) mixture one step 1) obtained is added to step 2) in the mixture two that obtains, stir, obtain the Radix Angelicae Sinensis slow seedling agent of the short root of root-naked transplanting of nursing young plants in hothouses.
The 3rd purpose of the present invention has been to provide the application of the slow seedling agent of the short root of root-naked transplanting in Radix Angelicae Sinensis greenhouse bareroot seedling is transplanted of nursing young plants in hothouses of above-mentioned a kind of Radix Angelicae Sinensis, described Radix Angelicae Sinensis is nursed young plants in hothouses the using method of the slow seedling agent of the short root of root-naked transplanting for before transplanting, after Radix Angelicae Sinensis greenhouse bareroot seedling is soaked to 3-5 hour in the slow seedling agent of the short root of root-naked transplanting, drain the solution on root surface, then transplant and get final product.
Beneficial effect of the present invention is: by soaking root compliance test result experimental data, can find out, Radix Angelicae Sinensis greenhouse seedling is used a kind of Radix Angelicae Sinensis provided by the invention slow seedling agent of the short root of root-naked transplanting of nursing young plants in hothouses, can promote Winter wheat, fast sending out, shorten transplanting seedling time, improve transplanting survival rate.
