Abstract

The invention discloses a kind of cultivation method of giant knotweed, its step is at first to be to put in order ground with selecting, selects thicker soil, loose, fertile loam, and leveling, rake are carefully; Next is the breeding of stem branch, and the stem branch is cut off at crotch, the stem branch is disposed across in the shallow ridges blinding compacting; The 3rd is transplant planting, when the long root of branch, sprout after, be cut into trifle from the branch node that sprouts, every trifle is a transplanting stock field planting; The 4th is field management, intertill and clean tillage, topdresses, waters; The 5th is to gather and preserve, and 2 years can begin to gather, and rhizome is processed the back storage.The inventive method is easy, and adopting the stem branch of giant knotweed is propagating materials, gets the direct implantation of stem branch, and survival rate is more than 98%.

Description

The cultivation method of giant knotweed

Technical field

The present invention relates to the wild breeding field of changeing family's kind of a kind of traditional Chinese medicine giant knotweed, more specifically relate to a kind of cultivation method of giant knotweed.

Background technology

Giant knotweed Polygonum Cuspidatum Sieb.et Zucc is polygonaceae perennial herb or semishrub plant, cries spot root, spot cane, radix dactylicapni again.Often be grown in the following patana of height above sea level 1400m, limes marginis, roadside, the moist place of sylvan life, mainly be distributed in provinces such as various places and Shaanxi on the south China the Changjiang river, Hubei, Sichuan.The giant knotweed rhizome is rich in as Polydatin, resveratrol, archen, Chrysophanol, Rhein etc., and its extract is widely used in multiple industries such as medicine, healthy product, cosmetics, and the international market demand space is very big.At present the giant knotweed medicinal material mainly come from wild resource, excavate for a long time and certainly will will cause excessively shortage of wild resource, therefore, carry out the research of giant knotweed artificial cultivation technique and just seem very urgent and necessary.According to the seldom ripe germinating to seedling of field observation giant knotweed seed, prolong with the root string and open-air procreation is many, its root is the main source of medicinal material, does propagating materials as relying on root, the easy like this amount of growth of root and the amount of excavating of causing reduces, and cutting the stipes cottage propagation with common stem secateurs almost is to survive.About document: the report of giant knotweed biological property and standardized cultivation technology (2004 (5) Shaanxi agricultural science 113) and Chinese medicine voluminous dictionary (1977, the first volume 1329-1331 of the Shanghai People's Press), breeding all is by seminal propagation and root division." the direct implantation of stem branch " of the present invention is a kind of new giant knotweed method for quickly breeding, and be promptly economical, convenient and easy again.

Summary of the invention

The object of the present invention is to provide a kind of cultivation method of giant knotweed, method is easy, and adopting the stem branch of giant knotweed is propagating materials, gets the direct implantation of stem branch, and survival rate is more than 98%.

In order to realize above-mentioned task, the present invention adopts following technical scheme: before giant knotweed is bloomed, adopt the stem branch of perennial giant knotweed, cut off at crotch, making branch is vertical bar, in cutting bed or chesson, branch is imbedded in the soil (sand), covered fine sand, by general cottage propagation management, about 9-10 days can eustipes part send out roots must and stem eye, hole pressing is apart from 60 * 30 field planting, and through field management, can gather in 2 years obtains the giant knotweed medicinal material.

Step of the present invention is:

1, must be before blooming, promptly Mei Nian 5-6 adopts during the month and cuts the stem branch.

2, cut off at the branch crotch, keep 5-10 node, making branch is the vertical bar that contains a plurality of stipes points, neatly imbeds in the soil (sand) by 10cm line-spacing strip, must guard against and can not be cut into sections from eustipes part.

3, treat long root after, and grow tender shoots, hole pressing is apart from 60 * 30cm field planting, every cave kind 1-2 brood body, bud point is upward to be put.

4, fine earth in the training waters normal root water.

The present invention compared with prior art has the following advantages and effect:

1, branch is nutritious before 5-6 month giant knotweed is bloomed, and helps surviving.

2, owing to be hollow in the giant knotweed stem branch, directly cutting the joint cuttage can not survive, and can keep branch nutrition to run off more than the node and keep 5-10, is convenient to take root.

3, with the direct implantation of stem branch, survival rate is more than 98%.

4, solved the problem of directly making propagating materials of giant knotweed medicinal material (root).

Embodiment

1. put in order to choosing ground: the cultivation giant knotweed must select weather warm, and rainfall is better or irrigate environmental condition easily, selects thicker soil, and loose, fertile loam is ploughed deeply (25-35cm) once for well with the soil, and leveling, rake are carefully.

2. stem branch breeding: before 5-6 month giant knotweed is bloomed, select healthy and strong anosis stem branch, cut off at crotch, making branch is vertical bar, opens the dark ditch of 5-8cm in chesson or sand, line-spacing 10cm, 1 in traverse stem branch, blinding compacting.Keep upper soll layer moistening, can water less or not water until rudiment is complete.

3. transplant planting: when the long root of branch, sprout after, be cut into trifle from the branch node that sprouts, every trifle is a transplanting stock, and the formation of bud and root must be arranged on every joint, hole pressing is apart from 60 * 30cm field planting.

4. field management: (1) intertill and clean tillage: growing period is intertill and clean tillage in time, annual assurance cultivation uproot 2-3 time, and the top layer, soil is moistening does not have weeds with the field to keep.Note hoeing up weeds shallow (2-4cm), can not hurt the root of giant knotweed.(2) topdress: giant knotweed should be executed farmyard manure.For before the early spring plant germination, open shallow ridges (3-5cm) at two interlines and bury and execute people's animal manure 2000kg/ mu.Nitrogenous fertilizer is generally seldom used in the giant knotweed cultivation, in case branches and leaves excessive growth.(3) water: the giant knotweed happiness is moistening, and under the situation of arid, its rhizome is thin and branch is more, influences its yield and quality, should in time water, and guarantees the demand to moisture content.

5. gather and preserve: gather (1): 2 years can begin to gather, and its root and rhizome are used as medicine, and all can excavate in spring and autumn, and the rhizome of excavating spring can stay the root segment that bud point is arranged that to do propagating materials standby earlier.(2) processing: the rhizome after excavating is removed fibrous root, end pin, and segment or section are dried, and put aeration-drying place, notes mildew-resistant, anti-damaging by worms, and medicine materical crude slice should be put wooden case, cylinder is stored.
