Abstract

The invention discloses a planting method of evening primrose. The method comprises the following steps: (1) selecting and preparing of a land, namely, selecting a plot, which is fertile in soil and good in drainage, of which previous crops are beans or melons, fertilizing a barnyard manure or a cake fertilizer as a base fertilizer, deeply harrowing, airing for 15-20 days, smashing, raking and bedding; (2) seeding, namely, digging a seed trench which is 2-3cm wide and 1-2cm deep, spreading a layer of mixture of vinegar residues and field soil in the trench, mixing seeds with 50% phoxim emulsifiable concentrate, fully mixing with fried straw powder at the ratio of 1 to 20, sowing in the trench, and then immediately suppressing, wherein the planting density is 25,000-36,000 plants/mu; (3) intertilling and weeding; (4) transplanting of fixed plants, namely, thinning or transplanting fixed plants when seedlings grow into a rosula form; (5) topdressing, namely, carrying out topdressing for the first time about 15 days after plant fixing, and carrying out topdressing for the second time when an early bud grows; (6) prevention and treatment of plant diseases and insect pests; and (7) harvest processing. The planting method of the evening primrose disclosed by the invention has the advantages of being simple and easy to operate and high in yield; and the quality of medicinal materials is improved.

Description

The implantation methods of a kind of oenothera erythrosepala

Technical field

The invention belongs to Chinese herbal medicine planting technology field, particularly relate to the implantation methods of a kind of oenothera erythrosepala.

Background technology

Oenothera erythrosepala, another name screwtree root, cordate telosma.It is warm in nature, and taste is sweet, bitter, is used as medicine with seed, containing palmitic acid, stearic acid, oleic acid, linolenic acid, linoleic acid etc.Remarkable result is had, all right treatment of obesity, rheumatic arthritis and schizophrenia etc., and the growth of energy inhibition cancer cell to reduction cholesterol and atherosclerosis.In recent years, medical circle shows γ ~ linolenic clinical research: γ ~ linolenic acid also has good improvement result to obesity, schizophrenia, woman month premenstrual syndrome, periodically mammary gland pain and inflammation (rheumatic arthritis, ulcer joint enteritis, ephritis etc.).This just imply that linolenic acid will play larger effect in field of medicaments.And oenothera erythrosepala is as being rich in one of linolenic Chinese herbal medicine, its application in the field of Chinese medicines will be more extensive.

Oenothera erythrosepala is the annual or biennial herb plant of Oenotheraceae.Its basal leaf is grown thickly in rosette-stape, cauline leaf alternate, the long and narrow lanceolar of lower blade, and upper blade is short and small; Stem is upright, branch, root meat before bolting, and white is loose, main root lignification after bolting; Yellow flower, Hua Jing 4 ~ 5 centimetres; Spend single leave armpit, faint yellow, diameter 5 centimetres; Cylindrical capsule, seed is tiny; Petal is heart-shaped, 6 ~ October of florescence, 8 ~ November of fructescence.Oenothera erythrosepala is cold-resistant, drought-enduring, barren-resistant, and happiness light, avoid ponding, adaptability is very strong, light and spacious in ventilation, and loose fertile, well-drained sandy loam all can grow, seedling energy open country safe overwintering.Seed, without resting stage, can be sowed after gathering.But due to the deterioration of ecotope, wild oenothera erythrosepala quantity reduces rapidly, in order to meet the demand of market, home and abroad to evening primrose oil, the present invention proposes a kind of method of artificial planting oenothera erythrosepala, be intended to solve wild resource quantity few, the problem of the medicinal material huge market demand.

Summary of the invention

The object of the invention is to: the implantation methods providing the oenothera erythrosepala that a kind of method is simple, medical material quanlity is high, meets the demand of Chinese Medicinal Materials Markets.

To achieve these goals, the present invention adopts following technical scheme:

An implantation methods for oenothera erythrosepala, comprises the following steps:

1) selection of land wholely: select fertile soil, draining good, front stubble is beans or melon plot, and every mu applies barnyard manure or base manure made by 3000 ~ 4000 kilograms, cake fertilizer, then ploughs deeply, and smash after shining 15 ~ 20 days and rake, and makes the furrow of 1.5 meters wide.

2) sow: the time is on October 8 ~ 25, in step 1) furrow that perform dig wide 2 ~ 3 centimetres, the seed furrow of dark 1 ~ 2 centimetre, and the mixture spreading that in ditch one deck becomes with field local soil type by vinegar grain; With 50% phoxim emulsifiable concentrate seed dressing, then be sowed in ditch after fully mixing in the ratio of 1:20 with the stalk powder fried, broadcast rear timely suppression, thickness of sowing is 2.5 ~ 3.6 ten thousand plants/acre.

3) intertill and clean tillage: can emerge for 10 ~ 15 days after broadcasting, but seedling is before the 2nd pair of true leaf stretches and weeds seedling fairly similar, can not intertill and clean tillage, only just can enter after the 2nd pair of true leaf expansion.

4) transplant determine strain: when seedling grows up to rosette-stape can thinning or transplant determine strain, seeding row spacing is 65 cm x 65 centimetres, during high 30 centimetres of plant, earths up around its base portion, then spread one deck horsehit preserve soil moisture.

5) topdress: within after determining strain about 15 days, carry out first time and topdress, based on fertilizer, can select muck or compost made of stalks, topdressing amount is 700 ~ 1,000,000 grams/acre; Impose during first flower bud second time fertile in order to blooming, solid, based on inorganic fertilizer or composite fertilizer, can select in urea, nitrogen-phosphorus-potassium compound fertilizer, diammonium phosphate, ammonium nitrate, superphosphate, rock phosphate, potassium chloride, ash, potassium dihydrogen phosphate one or more.

6) extermination of disease and insect pest: when after rot morbidity, plant root gradually variable color rots, and blade is wilted withered, after to cause complete stool withered, water root at its period of disease 1% limewash, 50% topsin, 1500 times of liquid or 75% tpn, 1000 times of liquid and prevent and treat; When withered spot disease occurs, prevent and treat with 50% mancozeb, 500 times of liquid or 50% carbendazim, 500 times of liquid at the initial stage of a disease.

7) pick and process: can gather when inflorescence has half mature, with secateurs, inflorescence be cut off, spreads and in the open place is dried, and after sloughing shell and impurity, proceeds to the storage of ventilated place.

Further, in step 2) in, the mixed proportion of vinegar grain and field soil is 1:20.

Further, in step 5) in, when second time is topdressed, the proportioning of inorganic fertilizer and composite fertilizer is 1:2.

The invention provides a kind of method of artificial planting oenothera erythrosepala, have the following advantages:

1) the present invention is prior to seeding first with 50% phoxim emulsifiable concentrate seed dressing, then after mix with the stalk powder fried under broadcast, effectively prevent and treat the generation of spot blight, reduce disease loss, increase economic efficiency.

2) oenothera erythrosepala implantation methods of the present invention has method simply, the advantage that output is high, and improves medical material quanlity, meets Chinese Medicinal Materials Markets demand.

3) the present invention prior to seeding, and in seed furrow, first spread the mixture that one deck is become with field local soil type by vinegar grain, so just serve the effect improving soil pH value, the planting environment keeping oenothera erythrosepala is faintly acid, improves emergence rate.

Embodiment

Below in conjunction with specific embodiment, technical scheme of the present invention is described further, so that the understanding of same domain technical staff.

Embodiment 1
