Section, greatly reduces production cost.
The method of an exemplary embodiment of the present invention, the no-tillage breeding root of purple-flowered peucedanum seedling includes following multiple steps.
Step A: selection plot
In this step, select to fall into disuse sandy loam wasteland of the time within 5 years as breeding plot.
Preferably, the waste ground of the sandy loam does not grow shrub and given birth to weeds are mainly shallow root system weeds, and the sand earth
The soil in native wasteland is in nature rarefaction and drains well, thus provides preferable growing environment.The present invention makes full use of the spare time
The breeding that wasteland resources carry out root of purple-flowered peucedanum seedling is set, cost of land has been saved and breeding effect is preferable.Wherein, soil falls into disuse time control
In 5 years preferably, if falling into disuse overlong time, weeds and shrub are more, are unfavorable for root of purple-flowered peucedanum breeding.
Step B: prepare kind of a root
Root of purple-flowered peucedanum root is truncated into the root of purple-flowered peucedanum root segment of 3~5cm, as kind of a root after using plant ash to starch root of purple-flowered peucedanum root segment receipts.
According to the present invention, above-mentioned root of purple-flowered peucedanum root can be root of purple-flowered peucedanum fresh root, such as root of purple-flowered peucedanum farmer provide root of purple-flowered peucedanum fresh root, here
Signified root of purple-flowered peucedanum fresh root are primarily referred to as direct-seeding and breed the root got, because it does not have culturing and transplanting seedlings link and artificial farming
Soil is typically more deep, and main root is more developed and lateral root is undeveloped, so in particular to for root；Or non-bolting is wild
The fresh root of purple-flowered peucedanum root system of root of purple-flowered peucedanum root system or artificial growth, root of purple-flowered peucedanum root system referred herein are the roots by culturing and transplanting seedlings link processing
System, root of purple-flowered peucedanum main root are damaged when digging seedling and transplanting, and main root growth is restricted but lateral root is relatively flourishing, therefore referred to as root system.
Wherein, what the present invention used is fresh root or root system, should have soil and the resting period is no more than for 24 hours in the cool.
Preferably, the diameter of selected root of purple-flowered peucedanum root is in 0.5cm or more, to guarantee the quality of maternal plant.By root of purple-flowered peucedanum root
After being truncated into the root segment of 3~5cm, root segment quantity obtained can breed more maternal plants, and the plant of 90% root segment breeding
Strain can bloom knot, and this mode for being significantly expanded breeding coefficient retains the medicinal material that soil breeding root of purple-flowered peucedanum seed is abandoned than fresh root
Opportunity cost caused by taking in will be greatly lowered.
Wherein, receiving slurry to root segment using plant ash may be implemented the effect of sterilization, be conducive to the eruption and life of maternal plant
It is long.
Step C: sowing kind root
By kind of root sowing on the breeding plot that step A is selected, wherein kind root is preferably close to soil surface and is placed.
It is close to kind of root again and covers one layer of ground hay, pushes down gap and compacting between kind of root with cogongrass later, while on ground hay again
Cover one layer of cogongrass.Specifically, the sowing time is early March, and the cloudy day for being preferably selected ground moistening after rain carries out kind of a root

Mu needs 6000 yuan；0 yuan of rent of soil；Site preparation opens 0 yuan of compartment expense；Kind 100 yuan/mu of root processing cost, needs 1500 yuan；Sowing
With covering 200 yuan/mu of expense, 3000 yuan are needed；250 yuan/mu of the expenses such as ground hay and cogongrass, needs 3750 yuan.Single mu of cost:
400 (kind root expense)+100 (processing of kind root)+0 (rent of soil)+0 (site preparation opens compartment)+200 (sowing, covering)+250 (cogongrass agricultures
Money)=950 yuan, 15 mu are 14250 yuan total.
The control group of the present embodiment is to take since seedling, intermediate to expand numerous side to breed root of purple-flowered peucedanum seedling without excavation
Formula, then relevant cost are as follows: 300 yuan/mu of seedling cost of field planting seedling needs 4500 yuan；1000 yuan/mu of crop field rent,
Need 15000 yuan；Site preparation opens compartment and beats 600 yuan/mu of nest, needs 9000 yuan；200 yuan/mu of seedling cost is planted, needs 3000 yuan；Intertillage
800 yuan/mu of weeding (2 years half), needs 12000 yuan；300 yuan/mu of the fertilizer means of agricultural production, needs 4500 yuan.Single mu of cost as a result: 300
(seedling cost)+1000 (crop field rent)+600 (site preparation opens compartment and beats nest)+200 (planting seedling cost)+800 (tillage and weedings)+300
(means of agricultural production fertilizer)=3200 yuan, 15 mu are 48000 yuan total.
The production cost contrast table of control group and experimental group in 2 embodiment 2 of table (in terms of 15 mu)
In conclusion the production process of root of purple-flowered peucedanum seedling is optimized in the present invention, using the big advantage of root of purple-flowered peucedanum grain weight,
It is sowed by using root of purple-flowered peucedanum root segment, while building seed and falling the environment that native table and spring next year seed germinate naturally naturally, exempted from
