Abstract

The invention provides a culture method for improving appearance quality of maca rootstocks. The culture method comprises the steps of soil preparation and moisture, seed treatment, seeding, seedling management and field management. The culture method is characterized by directly and uniformly sowing treated maca seeds onto the moist ground according to 0.2-0.3 kilogram of maca seeds per Mu, and thinning the seedlings according to a planting space of 15cm*20cm when the maca seedlings grow to have eight leaves and one core. According to the culture method provided by the invention, the roots of the transplanted maca seedlings are protected from being destroyed and bent, the rootstocks of the maca seedlings can grow longitudinally, and the forfication and branching of the maca seedlings are avoided; and compared with a maca product cultured by a seedling transplanting method, the maca product provided by the invention has the advantages in appearance, the main root of the maca product is clear and free from branches, and the root of the maca product has few fine hairs, so that the appearance quality of the maca rootstock is obviously improved, the processing of the maca product is benefited and the processing cost of the maca product is reduced.

Description

A kind of cultivation method that improves MAJIA Rhizome type quality

Technical field

The present invention relates to a kind of cultivation method that improves MAJIA Rhizome type quality.

Background technology

Maca (Lepidium meyenii Walp, transliteration is " agate coffee ") is the annual or 2 years raw herbaceous plant of Cruciferae (Cruciferae) separate row Vegetable spp (Lepidium).Agate coffee have antifatigue, anti-oxidant, strengthen immunity, improve sexual function, regulate internal secretion, improve the effects such as fertility.The method that the artificial planting of agate coffee is transplanted after adopting and growing seedlings at present, although the method can be controlled the quality of seedling preferably, after transplanting, MAJIA Rhizome bifurcated, the branch of results are more, and on rhizome, fine fleece is also more, bring difficulty to the processing of agate coffee product, increased agate coffee product processing cost.

Summary of the invention

The object of the invention is for the problems referred to above, a kind of cultivation method that improves MAJIA Rhizome type quality is provided.

The present invention is achieved in that and the present invention includes whole geographical moisture in the soil, seed treatment, sowing and seedling management, field management step, it is characterized in that treated agate coffee seed, be sown on moisture in the soil face by every mu of 0.2～0.3 kilogram of Direct Uniform, agate coffee seedling grows to eight leaves wholeheartedly time, carries out thinning according to the specification of 15 × 20 centimetres of seeding row spacings.

Adopt the present invention, while transplanting after having avoided agate coffee to grow seedlings, root damages and bending, assurance agate coffee shoot root stem is vertically grown, avoid bifurcated, Bifurcation Phenomenon, the agate coffee product of the present invention's results is compared with cultivating seedlings and transplanting method: main root is obvious, without branch, on root, fine hair is few, make MAJIA Rhizome type quality obviously improve (referring to following table), be conducive to the processing of agate coffee product, reduced agate coffee product processing cost.

Embodiment

Below in conjunction with embodiment, particular content of the present invention is described.

The present invention includes whole geographical moisture in the soil, seed treatment, sowing and seedling management, field management step:

1, whole geographical moisture in the soil

Select that the soil is porous, fertile, soil structure good, water source is level land or gentle slope ground easily, turns over after plough removal of impurities every mu and apply 1.5～2 tons of decomposed manures, dig and mix thoroughly, base area is block-shaped manages moisture in the soil with slope aspect, and moisture in the soil length is 8～10 meters, moisture in the soil is wide is 1.2～1.5 meters, and ditch depth is 0.25～0.3 meter.

2, seed treatment

Select the seed of producing in high, the high purity of maturity, germination rate is high, germination vigor is good first year, bask seeds 1～2 day, hot water treatment of seeds 36～48 hours with 30～35 ℃, when seed soaking, add 0.5% carbendazim or fenaminosulf.After pulling seed out, admix slow fire earth burning, vernalization under 20～25 ℃ of conditions, often spreads stirring seed out, sowing after 60% seed shows money or valuables one carries unintentionally.

3, sowing and seedling management

Sowing in 5～June, broadcast after front elder generation irrigates moisture in the soil face and spray 500～800 times of liquid of fenaminosulf, agate coffee seed is by 0.2～0.3 kilogram every mu, and Direct Uniform is sown on moisture in the soil face, sowing bonnet is burnt 0.2～0.3 centimetre, soil, and uniform fold pine tag, water permeable after, tiling nonwoven or sunshade net, keep in seedbed 15～25 ℃ of temperature in daytime, night 5～10 ℃ of temperature, the rate 60～70% of sheltering from heat or light, often waters and keep moisture in the soil face moistening daytime.After seedling all sprouts, remove pine tag, artificial weeding 1～2 time between nursery stage, sprayed bacillus and prevents and treats disease 1～2 time every 8～12 days, sprayed 500 times of liquid of fish albumen 1 time in the time that the agate coffee number of blade reaches 4～5 every 6～8 days, sprayed altogether 2～3 times.

4, thinning

Sow after 50～60 days, agate coffee seedling grows to eight leaves wholeheartedly time, opens nonwoven or sunshade net, carries out thinning according to the specification of 15 × 20 centimetres of seeding row spacings.

5, field management

In agate coffee process of growth, carry out artificial weeding 2～3 times, in the time that agate coffee leaf growth is the most vigorous, sprayed 500 times of liquid of fish albumen 1 time every 6～8 days, spray altogether 2～3 times.

6, results

Can gather in the crops by the end of December, individual plant weighs 35 grams of left and right, and per mu yield is more than 350 kilograms.
