High-quality and high-yield cultivation method for radix angelicae pubescentis

Technical Field

The invention relates to a cultivation method of medicinal plants, in particular to a cultivation method of radix angelicae pubescentis with high quality and high yield.

Background

The radix angelicae pubescentis is a traditional common Chinese medicinal material in China and is a dry root of Angelica crenata (oliv.) Diels of Umbelliferae. Has the effects of dispelling wind, eliminating dampness, dispelling cold, relieving pain and the like, is commonly used for treating wind-cold-dampness arthralgia, lumbago, knee pain, rheumatic arthralgia, wind-cold headache and the like, and is a key medicine for treating wind-cold-dampness arthralgia. Besides being used for clinical formulas, the traditional Chinese medicine is also an important raw material for Chinese patent medicine production, and has high medicinal value. Wild radix angelicae pubescentis grows in valleys, hills, grasses, bush centers or stream ditch edges of high and cold mountain areas with the elevation of 1400 + 2600 meters, and soil is rich in humus and fertile. The radix angelicae pubescentis is perennial root herbs, is suitable for cold, cool and humid climatic conditions, and has the characteristics of preferring yin, cold resistance, fertility and waterlogging. Wild radix angelicae pubescentis grows dispersedly and is inconvenient to collect, and at present, wild radix angelicae pubescentis is rare and mostly adopts an artificial cultivation method, but the overall yield is not high due to some defects in the cultivation technology.

Detailed Description

Embodiment 1, a high-quality and high-yield cultivation method for radix angelicae pubescentis, which comprises land selection and preparation, a propagation method, field management, disease and insect cellar control, harvesting and processing, and is performed according to the following methods:

2. the method comprises two propagation methods, wherein (1) the seeds are propagated, direct seeding is adopted, fresh seeds are collected in 10 months during winter sowing and immediately sown, spring sowing is carried out before and after clearness, drill sowing or bunch sowing is carried out, the drill sowing is carried out according to the row spacing of 50 cm, ditching is carried out for 3-4 cm in depth, the seeds are uniformly sowed into ditches, bunch sowing is carried out according to the row spacing of 50 cm and the bunch spacing of 20-30 cm, opening holes are required to be flat with large opening and large bottom, 10-15 seeds are sowed in each hole, soil is covered for 2-3 cm, slight pressing is carried out, about 1 kilogram of seeds is used per mu, and soil is kept moist before; (2) after the root buds are propagated in autumn, the overground part withers, a mother plant is dug out, root heads with the buds are cut off, holes are formed in the ridge according to the line spacing of 30 cm and the plant spacing of 20 cm, 1-2 root heads are placed in each hole, the buds stand upright and go upwards, the original bud heads which have germinated need to be planted with soil, the bud tips which do not emerge with soil are 3-4 cm below the soil surface, the surface soil is slightly compacted, watering is carried out for stabilizing the roots, and the seedlings emerge in spring of the 2 nd year;

3. performing field management, (1) intertillage weeding when seedlings are 15-30 cm high in spring by intertillage weeding, weeding for 1 time each month in the first 5-8 months, applying clear water manure after weeding, and removing field weeds in time at the seedling stage; (2) thinning and final singling when the height of the seedling directly sowed by the seeds is 20-30 cm, thinning, reserving 1-2 big seedlings at a distance of 30-50 cm, growing on the spot, transplanting separately, spring planting for 2-4 months, autumn planting for 9-10 months, preferably spring planting; (3) topdressing and stumping, namely, weeding and topdressing are combined and applied to pigs, cow dung and compost for 1 time respectively in spring, autumn and winter, and fertilization in winter can be mixed with mountain forest humus soil to topdressing root and stump forming, so that lodging is prevented and the plants can safely overwinter;
