Abstract

The invention relates to a medicinal plant cultivation method, in particular to a hydroponic angelica dahurica cultivation method. The method includes: selecting sterilized mature angelica dahurica seeds, soaking in clear water, putting soaked angelica dahurica seeds in planting plates, filling nutrient solution into the planting plates, timely adding nutrient solution after angelica dahurica takes roots and gives off seedlings, keeping the nutrient solution in a flow condition under external force, replacing the nutrient solution at regular intervals, cultivating by controlling illuminance and temperature, and harvesting when rootstocks of angelica dahurica are 10-15cm in length and 2-2.5cm in diameter. The hydroponic angelica dahurica cultivation method has the advantages that angelica dahurica cultivated according to the method is short in growth cycle, the rootstocks can be harvested in one year, plant diseases and insect pests are avoided, the rootstocks are trim, thick and solid, and high mealiness, rich fragrance and high survival rate are achieved.

Description

A kind of cultivation method of the water planting root of Dahurain angelica

Technical field

The present invention relates to a kind of cultivation method of medicinal plant, be specifically related to a kind of cultivation method of the water planting root of Dahurain angelica.

Background technology

The root of Dahurain angelica is the plant of Umbelliferae angelica, be distributed in the ground such as northeast and North China of China's Mainland, be grown on height above sea level 200 meters to 1, the area of 500 meters, generally be born in sylvan life, border, by small stream, shrubbery and meadow, mountain valley, there is wines used as antirheumatic, to invigorate blood circulation apocenosis, myogenic pain relieving, for headache, toothache, nasosinusitis, intestines wind anal fistula, leukorrhea with reddish discharge, ulcer sores, pruitus, because the application of the medical aspect of the root of Dahurain angelica widely and have edibility simultaneously, therefore requirement is very large, but the amount wild because of the root of Dahurain angelica is very little, can not meet now medical and edible demand at all, therefore artificial cultivation is carried out imperative.The emergence rate of existing artificial seeding's method gained is low, and plant is short and small, and root development is bad.

Summary of the invention

The object of this invention is to provide a kind of good and water planting root of Dahurain angelica method that bud ratio is high of root development.

A cultivation method for the water planting root of Dahurain angelica, it comprises the following steps:

Select the root of Dahurain angelica seed after ripe sterilization, put into clear water and soak 12-16 hour;

After immersion, root of Dahurain angelica seed is put into field planting dish, in fixed planting pot, inject nutrient solution, the height of nutrient solution is 5-6cm, changes one time of nutrition liquid every 10 days, and growing temperatures is 22 DEG C, and intensity of illumination is 1000-1500Lx;

After the root of Dahurain angelica is taken root and grown seedling, add nutrient solution in time, make nutrient solution be enough to flood the root of the root of Dahurain angelica, make nutrient solution keep flow regime by external force, flow rate is 60m/min, within every 15 days, changes one time of nutrition liquid, growing temperatures is 23 DEG C, and intensity of illumination is 2000-2500Lx;

When the root of Dahurain angelica grows to more than 10cm height, spray a chlormequat every other month, and timely trimming leaf, control the quantity of petiole at 6-8 root, make nutrient solution keep flow regime by external force, flow rate is 60m/min, within every 15 days, changes one time of nutrition liquid, growing temperatures is 20 DEG C, and intensity of illumination is 4000-4500Lx;

The rhizome length being cultured to the root of Dahurain angelica is 10cm-15cm, and diameter is 2-2.5cm;

Wherein, nutrient composition and concentration thereof are (mg/L): ammoniacal liquor 100-150.2, calcium cyanamide 50-80.6, calcium phosphate 200-230.4, potassium pyrophosphate 150-180.2, B (OH) 310-15.4, basic zinc carbonate 0.02-0.03, ferrous sulfate 0.02-0.03, sodium molybdate 0.01-0.02, copper sulphate 0.015-0.03, nitrate of lime 0.1-0.3, silica 0.002-0.004, heteroauxin 4-5, gibberellin 2-3 part, basic element of cell division 2-3 part, glucose 100-150.

Beneficial effect of the present invention is, through the root of Dahurain angelica that this cultivates, growth cycle is shorter, rhizome of just can gathering for 1 year, and without damage by disease and insect occur, rhizome is neatly sturdy, mealiness foot, give off a strong fragrance, survival rate is high.

Embodiment

Select the root of Dahurain angelica seed after ripe sterilization, put into clear water and soak 14 hours;

After immersion, root of Dahurain angelica seed is put into field planting dish, in fixed planting pot, inject nutrient solution, the height of nutrient solution is 5cm, changes one time of nutrition liquid every 10 days, and growing temperatures is 22 DEG C, and intensity of illumination is 1200Lx;

After the root of Dahurain angelica is taken root and grown seedling, add nutrient solution in time, make nutrient solution be enough to flood the root of the root of Dahurain angelica, make nutrient solution keep flow regime by external force, flow rate is 60m/min, within every 15 days, changes one time of nutrition liquid, growing temperatures is 23 DEG C, and intensity of illumination is 2200Lx;

When the root of Dahurain angelica grows to more than 10cm height, spray a chlormequat every other month, and timely trimming leaf, control the quantity of petiole at 6, make nutrient solution keep flow regime by external force, flow rate is 60m/min, within every 15 days, changes one time of nutrition liquid, growing temperatures is 20 DEG C, and intensity of illumination is 4200Lx;
