Description

A kind of mating system of the fleece-flower root

Technical field

The present invention relates to a kind of fleece-flower root seedling-cultivating method.

Background technology

The fleece-flower root call, Polygonum multiflower knotweed, silk tree rattan, smart, be polygonaceae perennial winding liane.Root is elongated, and end becomes loose block root, and appearance bronzing is to crineous.Respectively, the block root of plant, rattan and leaf all can hyoscines, and Chinese medicine name is respectively: the fleece-flower root, Polygonum multiflower knotweed, tuber fleeceflower leaf for medicinal effects.The Chinese medicine fleece-flower root have Radix Polygoni Multiflori and RADIX POLYGONI MULTIFLORI PREPARATA point: Radix Polygoni Multiflori function is detoxified, relax bowel, disappear carbuncle; RADIX POLYGONI MULTIFLORI PREPARATA function enrich and benefit essence and blood, black beard and hair, strengthening the bones and muscles, filling liver kidney.

The fleece-flower root seedling-cultivating method that tradition adopts: seedling raise period generally selects part from January to February, with annual old tendril or still immature rattan as cuttage seeding, be cut into 2----3 eye, be about the cutting of 20 cm, article 40 to 100, be bundled into a bundle, yellow mud is dipped in lower end, and storing frescade is for subsequent use; Open traverse furrow by line-spacing 10-15 centimetres, ditch depth 10 centimetres, puts the cutting got ready by furrow bank, spacing in the rows 1 centimetre, and earthing compacting, makes clip slightly basset, then lid layer straw, and about about 100 days, seedling grew to 15---can land for growing field crops be transplanted to when 20 centimetres.

Mainly there is following problem in prior art:

One, the tendril of nursery has has tender always, and having carefully has thick, and the full rate of bud is not high, does not have special nursery kind rattan plot, and the tendril adopting under is not by sterilization, and seriously, cutting lower end clip is inconsistent, poor stability, and planting percent is low for courses of infection;

Two, soil is exposed to the sun without ploughing deeply the sun, does not carry out soil sterilization sterilization;

Three, cuttage branch lower end clip is inconsistent, and root of hair is slow;

Four, cuttage bar does not add clean yellow mud with root-inducing powder, and easy dehydration is dried up;

Five, lime sulfur is not sprayed before rudiment;

Six; Do not set up seedbed standard design, be not easy to field management;

Seven: newborn long shoot reaches 20 centimetres and do not cut top, free growth, after fleece-flower root germinating time has and first has, the tendril first grown covers the shoot growth point of rear sprout growth, the rudiment point delaying growth can not get sufficient sunlight, and be easily subject to various courses of infection, planting percent is low.

Summary of the invention

For the deficiencies in the prior art part, the present invention aims to provide a kind of fleece-flower root seedling-cultivating method, and mainly solve above-mentioned shortcoming, and a kind of seedling raise period provided is short, planting percent is high, the fleece-flower root seedling-cultivating method of stable yield.

Technical scheme of the present invention: a kind of fleece-flower root seedling-cultivating method, comprises the steps:

(1) set up the special plot of fleece-flower root nursery, cultivate high-quality stolon rattan, stolon rattan is close to ground surface soil, and internode is shorter, and 90% joint growth has vapour to take root root system, and branch is in the same size, is to determine fleece-flower root survival rate of seedling height key point;

(2) 8-September of the nursery Season select lunar calendar;

(3) Caiyu seedling stem rattan avoids misty rain weather, the non-lignification place of stem rattan cuts, a wisp is bundled into by 100, according to nursery consumption, be soaked in the mould spirit dilution of 30% evil 400 times of solution 20-30 minutes, take out and drain liquid, then every bar rattan is by cutting a bit of every three bud joints, upper clip is level and smooth, and lower clip is tiltedly level and smooth, and each hundred cuttage bar is bundled into one by upper and lower clip;

(4) cuttage bar process: fresh yellow clay, clean water, root-inducing powder, evil mould spirit=300:300:0.1:1 are mixed the mud mixed by quality proportioning, fleece-flower root wisp lower end is invaded and to steep in mud 10-15 minutes, flood second section to be as the criterion, discharge after taking-up slurries are slightly dry in clean shady and cool place, spell and accomplish that nursery process cuttage on the same day is complete;

(5) seedbed selection of land: suitable selection of land is smooth, irrigation and drainage are convenient, loose fertile sandy loam, the cuttage previous moon ploughs 25-30 centimetres, soil, and every mu is spilt quicklime 100 kilograms, sterilizes to soil comprehensively killing, after one week, every mu is spilt and executes Chemical Mixed Fertilizer 100 kilograms, apply fertilizer latter 20 days, fertilizer transforms completely, does not cause fertilizer damage to cuttage bar clip;

(6) railway carriage or compartment, seedbed face width one meter, furrow width 25 centimetres, ditch depth 20 centimetres, after arrangement, every mu of use 70 to 80 milliliters of sprinklings weed killer herbicide;

(7) the seedling time is arranged and spraying herbicide interval is 10 to 15 days, valley is dug in face, railway carriage or compartment, dark 10 to 15 centimetres, by the cutting handled well by oblique spacing in the rows 4 centimetres discharge, then cover first row cutting with the fine earth digging the second row, lid is above the second bud, trample tight, second row and first row neatly discharge, and keep line-spacing 10 centimetres, lid layer 1-1.5 centimetres of straw, water foot surely with water;

(8) budding period management: according to local temperature condition, eye starts to sprout when expanding, and sprays the lime sulfur solution of dilution 90 times;

(9) seedling management; Pinch when seedling grows to 15 centimetres high, control its growth, ensure nursery stock neat and consistent.

Above-mentioned fleece-flower root seedling-cultivating method and traditional seedling-cultivating method have the following advantages.

1, build special nursery plot, it is consistent to plant rattan specification, and the bud joint growth of stolon rattan more than 90% has vapour to take root to be;

2, nursery to be in the fleece-flower root second time summit of growth phase season, and avoid storm wind heavy rain season, damage by disease and insect incidence is few;

3, collect seedling rattan time avoid wind and rain mist wet weather;

4, new cadmium yellow clay, take root, dislike mould spirit, yellow clay is the very stable material of a kind of moisture absorbability and moisture retentivity, and add root-inducing powder, yellow clay has dislikes mould spirit protection, and new root is seldom subject to courses of infection;

5, nursery soil ploughs deeply sterilizing fertilising has the regular hour to arrange, quicklime is basic mineral, fleece-flower root producing region is nearly all acid ground, germ in acid ground, run into strong basicity, eliminated immediately, P in soil H value is improved, by after biological transformation, just fertilizer damage must can be avoided with Chemical Mixed Fertilizer;

6, seedbed control grass; Nursery weeding is a very strong link of consumption labour, because fleece-flower root seedling density is very large, artificial weeding difficulty, after adopting face, railway carriage or compartment to arrange, spraying herbicide, has very strong killing power to annual gramineae, isolate after 10 days, seedlings plugging does not have an impact, and whole seedling stage grows grass very sparse, reduces nursery labour cost;

7, seedling is arranged, traditional cottage method, because Caulis Polygoni Multiflori rattan is more pliable and tougher, when inserting soil, first segment clip cortex is easy to damage, is subject to courses of infection, is lowered into motility rate, too much consuming time, adopt valley row seedling, branch lower end clip cortex is not subject to any damage, and nursery speed is fast, and survival rate is high;

8, seedling growth is more weak the budding period, and resistivity is poor, easily suffers that damage by disease and insect is attacked, and when eye expands, sprays lime sulfur, has very strong lethality to aphid and fungi;

9, traditional seedling management, after branch rattan grows, allow its free growth, vine is wound around mutually, because the growth of fleece-flower root rattan is fast, easily cause closing, weak branch is wound around by enriching shoot, weak branch can not get growing space, progressively dead, the time lethality that rainwater is many is very high, cut the heart when adopting seedling to grow to 15 centimetres to pinch, should be after pinching, new growing point just will send through more than ten days time, there is provided Time and place to the slow shoot growth that germinates, vine can not be allowed between whole nursery stage to be wound around mutually, see to twine and just cut, promote that base portion is sturdy, well developed root system, lay high yield basis to immigration land for growing field crops.
