Description

A kind of astragalus mongolicus high ridge seedbed drip irrigation seedling growing process
Technical field:
The present invention relates to a kind of technology adopting the mode of high ridge seedbed drip irrigation to carry out astragalus mongolicus nursery.
Background technology:
" Chinese Pharmacopoeia " 2010 editions regulation Radix Astragali Original plants are pulse family Astragalus Astragalus membranacus and astragalus mongolicus, but Root Morphology variation is comparatively large in the course of cultivation due to Astragalus membranacus, and astragalus mongolicus is relatively stable.Therefore, astragalus mongolicus is cultivated in recent years and the main flow of Genus Astragalus of Local Used Commercial Huang.
Traditionally, the mode that astragalus mongolicus mainly adopts artificial breeding to transplant is planted.Covering of a seed is hard not easily permeable, soaks, to roll or the mode such as acid treatment impels it to germinate usually through boiling water.Annual the first tenday period of a month May in spring carry out sowing seeds nursery after leveling is ploughed deeply in soil, adopt the mode of broad irrigation to carry out watering irrigating, dig transplantation of seedlings April in Second Year.
Should be noted that following problems in astragalus mongolicus seedling raising process: seed sprouting and Seedling Stage need adequate water, otherwise do not emerge or because of arid and dead; In process of growth, To Be Protected from Heat, is afraid of that ponding flood is hollow, as excess moisture easily occurs rotten; Astragalus mongolicus belongs to phreatophyte, and soil layer is thin, and root grows wild more, and branch is many, in shank shape, of poor quality; Because northern area rainwater is few, dry, moisture evaporation is fast, and traditional irrigation canals and ditches are irrigated or broad irrigation mode easily causes and irrigates uneven and upper soll layer and harden, cause astragalus mongolicus seeding ratio low, seedling percent is low, to produce rice shoot length short, diameter is thin, and quality can not be guaranteed.
This traditional seedling raising manners also exists the problems such as percentage of seedgermination is not high, seed consumption is large, agricultural production efficiency is low, production cost is high, quality of medicinal material can not be guaranteed.
Summary of the invention:
For solving the problem, the invention provides a kind of new astragalus mongolicus seedling growing process.Adopt the mode of high ridge seedbed drip irrigation that seed consumption can be made to reduce, percentage of seedgermination, survival rate improve, and rice shoot length increases, and mechanization degree significantly promotes, and cost of labor significantly reduces, the astragalus mongolicus rice shoot that profit obtains in this way, and quality is higher.
The present invention adopts following technical scheme: a kind of astragalus mongolicus high ridge seedbed drip irrigation seedling growing process, comprises the steps:
(1) inspection of seed
Seed is tested, requires cleanliness >=85%, germination rate >=60%, other plant seed weight≤0.4%, moisture≤12%, seed after the assay was approved, under the condition of be kept at drying, feel nice and cool, ventilating;
(2) selection of nursery
Selection soil is the deep soil of sandy loam, soil layer, can not continuous cropping;
(3) high ridge seedbed Facilities Construction
Ploughing wholely: autumn or spring turn over, and with tractor, nursery are ploughed deeply 20 ~ more than 50cm, applying base manure in conjunction with ploughing, execute farmyard manure 1000 ~ 3000kg, flatten with disk harrow for every mu;
Do seedbed: before sowing in spring, be used as a machine and make seedbed on the arable land ploughing deeply leveling, make bed surface smooth, loosing soil, the wide 1.0 ~ 1.5m in seedbed, seedbed height 25 ~ 35cm, between adjacent seedbed, interval 40cm is as field management service aisle;
(4) sow, lay drip irrigation system
Sowing: the seed precision sower handled well is sowed on bed surface, ditching depth 2 ~ 3cm, earthing 1 ~ 2cm, line-spacing 20 ~ 30cm, sowing quantity 4 ~ 5kg/667m 2, execute diammonium phosphate 10kg/667m simultaneously 2;
Lay drip irrigation system: each bed surface lays 2 ~ 5 drip irrigation pipe, about the spacing 40cm of every root drip irrigation pipe, or often lay drip irrigation pipe 1 in the ranks on bed surface;
(5) field management
After planting seed and drip irrigation system lay, timely unlatching drip irrigation system irrigates 3 ~ 5 hours first, within every 3 ~ 5 days later, look soil moisture drip irrigation 0.5 ~ 1 hour, until when seed sprouting, seedling grow 4 ~ 6 compound leaves, now carry out first pass intertill and clean tillage with cultivator, and carry out artificial thinning simultaneously, keep spacing about the 1 ~ 2cm of seedling and seedling, backsight young plant growing state adopt machinery in time or manually carry out watering, hoe up weeds, deinsectization, the field work such as fertilising;
(6) lifting: before seedling germinates after Second Year thaws the beginning of spring, dug out rice shoot for transplanting land for growing field crops with seedling digging machine at the beginning of about by the end of April or 5 months.
The beneficial effect of employing technique scheme is:
(1) be conducive to saving astragalus mongolicus seed consumption.The sub-skewness of breeding is disseminated, every mu of sowing quantity 11 ~ 13kg in tradition land for growing field crops.Adopt precision sower, sowing accurately, to economize kind, laborsaving, every mu of sowing quantity only needs 4 ~ 5kg.
(2) be conducive to improving astragalus mongolicus percentage of seedgermination.Astragalus mongolicus seed sprouting and Seedling Stage need adequate water.High ridge seedbed drip irrigation system can evenly and exactly instill in the soil horizon at soil surface near crop root zone or crop root place, directly moisture is transported to astragalus mongolicus seedling root, provide the adequate water needed for root growth, be conducive to seed sprouting and growth of seedling; Long-term, moistening soil that is that continue provides the control environment of astragalus mongolicus seed sprouting simultaneously, and seed does not need pretreatment directly to sow, and germination rate is increased to more than 80%, and seedling percent reaches more than 90%.
(3) be conducive to improving astragalus mongolicus quality of medicinal material.The quality of seedlings determines the quality of medicinal material, and traditional implantation methods seedbed is generally 15 ~ 20cm, when astragalus mongolicus seedling grows to 20cm, runs into solid soil and easily bifurcated occurs.High ridge seedbed is highly generally 25 ~ 35cm, for astragalus mongolicus nursery provides the loam that required soil layer is deep, the soil is porous, be conducive to seed sprouting and growth of seedling, keep seedbed below ground 10 ~ 11cm thickness soil to soak simultaneously and namely stop drip irrigation, be conducive to the astragalus mongolicus system of taproot deeply penetrate soil and suppress the growth of fibrous root, seedling system of taproot average length increases more than 10cm, and bifurcated is few.
(4) be conducive to improve agricultural production efficiency, water saving, economize on electricity, laborsaving, reduce production cost.Employing is made a machine and is sat seedbed, precision sower sowing, and mechanization degree significantly promotes; Meanwhile, drip irrigation is than spray irrigation economize 30% ~ 40%, and economize on electricity 20% ~ 30%, than pouring water saving 70% ~ 80%, economize on electricity 75 ~ 85%, compared with broad irrigation, can increase production 20% ~ 30%, therefore, drip irrigation greatly reduces water, electricity and cost of labor, and then improves and ensure that economic benefit.Radix Astragali rice shoot root is generally 20 ~ 30cm, and tradition adopts excavated by manual work seedling, and the present invention by setting up high ridge seedbed, then can realize mechanization and dig seedling, ° not only increases production efficiency, can also reduce the extent of damage to medicinal material root.
