Abstract

The invention discloses a method for planting isatis roots on sand soil land parcels. The planting process comprises five steps of soil selection and preparation, sowing, field management, pest and disease damage prevention and harvest. The method adopts distillers' grains as a base fertilizer and traditional Chinese medicine residues as additional fertilizers, is excellent in reasonable application of a microelement fertilizer, a potash fertilizer, a molybdenum fertilizer, a zinc fertilizer and the like, and can greatly improve the yield of isatis roots. According to the invention, the traditional Chinese medicine materials are adopted for seed soaking and the traditional Chinese medicine material liquor is sprayed for precaution, so that pest and disease damages to the isatis roots are greatly reduced, and the growth environment of the isatis roots is purified. When the method is adopted for planting, the isatis roots are kept away from pest and disease damages on the whole.

Description

The implantation methods of a kind of sand plot Radix Isatidis

Technical field

The implantation methods that the present invention relates to a kind of sand plot Radix Isatidis, belongs to field of plant growing technology.

Background technology

Radix Isatidis is called large indigo, ancient name for Chinese cabbage orchid, ancient name for Chinese cabbage green grass or young crops, smalt etc.For Cruciferae biennial herb.With the root title Radix Isatidis that is used as medicine, with leaf, be used as medicine and claim folium isatidis, root and leaf bitter, cold in nature.Have function clearing heat and detoxicating, blood cooling and ecchymoses removing, normal and other Chinese medicine composition compound, is widely used in various diseases as influenza, encephalitis, hepatitis etc.Radix Isatidis is distributed in the ground such as China Inner Mongol, Shaanxi, Gansu, Hebei, Shandong, Jiangsu, Zhejiang, Anhui, Guizhou.

The source difference of Radix Isatidis, is used as Chinese medicine, also there are differences, and shows as clinically the difference in drug effect.This is relevant with concrete cultivation method and production environment, and the Radix Isatidis that therefore how to obtain high-quality and high yield is the target that Radix Isatidis plant personnel and enterprise are pursued.

Summary of the invention

The object of this invention is to provide the implantation methods of a kind of sand plot Radix Isatidis, profit can improve the yield and quality of Radix Isatidis in this way effectively.

For reaching above object, the present invention adopts following technical scheme:

The implantation methods of a kind of sand plot Radix Isatidis comprises following content:

(1) the whole ground of selection of land

Select draining good, fertile loose sand plot plantation, every mu of barnyard manure 4000-5000 kg that executes to become thoroughly decomposed, superphosphate 50-80 kg, potassium sulfate 20-30 kg, urea 15-20 kg, carbon ammonium 30-40 kg, peat composed of rotten mosses 500-600 kg, alum 3-5 kg mix and stir and use, evenly be spread on and in ground, plough deeply 30-40cm, then make flat furrow, sow waiting;

(2) sowing

Early April, the liquid first Radix Isatidis seed being made into the 10-15% traditional Chinese medicine extract powder of 40-50 ℃ seed soaking 10-12 h, pulls out and mixes ash after drying and broadcast sowing; The liquid that 10-15% traditional Chinese medicine extract powder is made into is: 8-10 weight portion Radix Isatidis, the 8-10 weight portion tuber of stemona, 10-12 weight portion paulownia sawdust, 8-10 weight portion tea root add decocting to boil, collect filtrate to be condensed into dried powder and to obtain traditional Chinese medicine extract, then above-mentioned powder is made into the liquid that mass concentration is 10-15%;

(3) field management

When height of seedling 8-10 cm, in conjunction with intertill and clean tillage, carry out thinning, press the final singling of 7-10 cm spacing in the rows, the transplanting of simultaneously filling the gaps with seedlings during thinning, to guarantee full stand, after final singling, in conjunction with intertillage, repeatedly topdress, mu is executed slow-release carbamide 3-5 Kg, soya bean grouts 100-120 Kg, potassium sulfate 10-15 Kg, ferrous sulfate 2-3 Kg, borax 0.5-1.0 Kg, Radix Isatidis or folium isatidis dregs of a decoction 200-240 Kg, composite microbiological fertilizer 3-5 Kg, living bacteria count in composite microbiological fertilizer >=0.2 hundred million/gram, during arid, should water in time, should note ditch cleaning draining rainy season, prevent rotten of ponding and introduced disease between furrow,

Folium isatidis sprayed the potash fertilizer of molydbenum fertilizer that blade face concentration is 0.1-0.2% and 0.1-0.2% zinc fertilizer, 0.1-0.2% vegetative period every three weeks;

(4) damage by disease and insect prevention

In whole vegetative period, the Chinese medicine preventing disease and pest agent of converting 300-400 times of water for one time every spray in 1-2 month, described Chinese medicine preventing disease and pest agent is by following raw materials in part by weight: 8-10 part rhizoma nardostachyos, 8-10 part root of langdu, 10-12 part tuber of stemona, 8-10 part wilson passionflower herb, 8-10 part Swamp Mahogany Leaf add decocting to boil, collect filtrate to be condensed into dried powder and to make;

(5) gather

Annual harvesting folium isatidis 2～3 times, for the first time in mid-June; For the second time in late August; In conjunction with receiving root, cut off overground part November for the third time, select qualified blade to be used as medicine.

The described molydbenum fertilizer of step (3) is ammonium molybdate or sodium molybdate, and zinc fertilizer is zinc sulphate or zinc chloride, and potash fertilizer is borax or boric acid.

The present invention has following beneficial effect:

1. implantation methods of the present invention, by execute the peat composed of rotten mosses as base manure, Chinese medicine slag as topdressing, the reasonable use of outstanding micro-fertile potash fertilizer, molydbenum fertilizer, zinc fertilizer etc., can greatly improve the output of Radix Isatidis, every per mu yield Radix Isatidis 450-550 kilogram, folium isatidis 200-250 kilogram.Than normal plantation per mu yield, increase more than 25%.

2. the present invention, by adopting traditional Chinese medicine seed soaking, the prevention of traditional Chinese medicine liquid to spray, can greatly reduce Radix Isatidis damage by disease and insect, has purified the growing environment of Radix Isatidis, and in the invention process planting process, Radix Isatidis there is no generation damage by disease and insect.
