Abstract

The invention relates to the technical field of seedling cultivation of traditional Chinese medicinal materials and specifically relates to a seedling cultivating method for angelica sinensis. The method comprises the steps of land selecting, land preparation, seeding, seedbed management, seedling lifting and storage. By employing the seedling cultivating method, angelica sinensis is high in emergence rate and yield.

Description

A kind of seedling-cultivating method of Radix Angelicae Sinensis

Technical field

The present invention relates to a kind of seedling-cultivating method of Radix Angelicae Sinensis.Belong to field of agricultural cultivation.

Background technology

China's Radix Angelicae Sinensis seedling-cultivating method is the earliest: (1) wholely: plough with choosing; (2) sow: seed is evenly sprinkled into ground, then trimly throw with rake and turn over, seed is imbedded the lower 2-3cm of soil; (3) lid grass.This seedling-cultivating method is too coarse, and emergence rate is low.

Summary of the invention

The object of the invention is to develop a kind of Radix Angelicae Sinensis seedling-cultivating method, through field trial, this method emergence rate is high, simple to operation.Its cultivation method is as follows:

One, propagation method

1, selection of land: late May-early June, select that the soil is porous is fertile, be rich in humus, deep, the well-drained black mature soil of soil layer, blackland carry out nursery, require that the gradient is less than 20-25 °; 2, wholely, apply fertilizer: within 10 days before broadcasting, carry out wholely.Whole in conjunction with ploughing deeply, mu executes diammonium phosphate about 30-40 kgs/acre, rakes and does furrow, furrow face width 60-80 centimetres, and furrow spacing 20 centimetres, furrow are high 15 centimetres, and furrow are to same slope aspect; 3, seed is selected and process: selects 3 years raw normal matures, preserve well, nothing is gone mouldy, anosis worm, germination rate more than 70% seed, broadcast first 1 day per kilogram seed 50% carbendazim or root 'qifuling ' powdered agent 5g dresses seed; 4, sow: late May-early June loses no time in sowing while there is sufficient moisture in the soil sowing, the amount of broadcasting about 5 kgs/acre.During sowing, seed is evenly sprinkled into by whole good furrow face, suppresses a little, earthing 0.3-0.5 centimetre, after planting uniform fold one deck wheat stalk, overlay capacity 400-500 kg/acre, thick about 3 centimetres, moisturizing of shading, keep soil from packing together, in order to emerging, after covering, interval 2m soil zone pushes down covering, in order to avoid wind; 5, seedbed management: emerge for after planting about 20 days.When returning July seedling to grow 1-2 true leaves, choose loose seedbed covering, first time uprooting weed; Height of seedling 4 centimetres, when namely August, the 4th true leaf grew, pull out second time grass, select the cloudy day to throw off covering.Weed in seedbed to be extracted in time, prevent disease worm from endangering.Every mu of use 40% phoxim 40 milliliters is watered 45 kilograms of sprayings and carries out flea beetle control, every control in 7 days once, sprays 2 times; Thinning, final singling is carried out, seedling spacing about 2 centimetres in conjunction with weeding.

Two, lifting and storage

1, lifting: the young plant cultivated late September-early October lifting, be placed on the storage of suitable place; 2, seedling is selected: seedling, excessively seedlings will be crossed by underproof during lifting, or the too much seedling of side root, sick seedling, insect bite and mechanical damage seedling pick; 3, seedling is tied: after young plant digs out selection, seize the blade on seedling, leave the petiole of about 1 centimeter length, about 100 seedlings are bundled into one; 4, dry in the air seedling: at the shady and cool dry place that ventilates, by seedling one leaning on one, the symptom of a trend is tiltedly put outwardly in the ground being covered with the thin dry immature soil, makes it to lose portion of water; 5, seedling is store: by the seedling dried well, in early November, alternatively gesture high, ventilate, shady and cool place digs dark wide each 1 meter, be about the hole of 2 meters, stack with the half-dried immature soil and young plant layering, every layer of seedling shoot thickness 5-7 centimetre, every layer of thick about 2-3 centimetre of soil, pile 10 centimetres above ground level of sub-top earthing, prevent ponding.

Claims

1. the seedling-cultivating method of a Radix Angelicae Sinensis.

2. the seedling-cultivating method of Radix Angelicae Sinensis according to claim 1: select the gradient to be less than 20-25 °, the soil is porous, and fertile blackland carries out nursery; Within 10 days before broadcasting, carry out wholely; Whole in conjunction with ploughing deeply, mu executes diammonium phosphate about 30-40 kgs/acre, rakes and does furrow, furrow face width 100-120 centimetres, and furrow spacing 30 centimetres, furrow are high 15 centimetres, and furrow are to same slope aspect; Select 3 years raw normal matures, preserve good, without going mouldy, anosis worm, germination rate more than 70% seed, broadcast first 1 day per kilogram seed 50% carbendazim or root 'qifuling ' powdered agent 5g dresses seed; Late May-early June loses no time in sowing while there is sufficient moisture in the soil sowing, the amount of broadcasting about 5 kgs/acre, during sowing, seed is evenly sprinkled into by whole good furrow face, suppress a little, earthing 0.3-0.5 centimetre, after planting uniform fold one deck grass, overlay capacity 400-500 kg/acre, thick about 3 centimetres, shading moisturizing, keeping soil from packing together, in order to emerging; After covering, interval 1.5m soil zone pushes down covering, in order to avoid wind; Within after planting about 20 days, emerge, when returning July seedling to grow 1-2 true leaves, choose loose seedbed covering, first time uprooting weed; Height of seedling 4 centimetres, when namely August, the 4th true leaf grew, pull out second time grass, select the cloudy day to throw off covering; Weed in seedbed to be extracted in time, prevent disease worm from endangering; Every mu of use 40% phoxim 40 milliliters is watered 45 kilograms of sprayings and carries out flea beetle control, every control in 7 days once, sprays 2 times; Thinning, final singling is carried out, seedling spacing about 2 centimetres in conjunction with weeding; The young plant cultivated late September-early October lifting, be placed on the storage of suitable place, the seedling risen to be dried in the air at the shady and cool dry place of ventilation seedling, and seedling one handle is leaned on one, and the symptom of a trend is tiltedly put outwardly in the ground being covered with the thin dry immature soil, makes it to lose portion of water; By the seedling dried well, in early November, alternatively gesture high, ventilate, shady and cool place digs dark wide each 1 meter, be about the hole of 2 meters, stack with the half-dried immature soil and young plant layering, every layer of seedling shoot thickness 5-7 centimetres, every layer of thick about 2-3 centimetre of soil, piles 10 centimetres above ground level of sub-top earthing, prevents ponding.
