Purple potato will become one of primary raw material of anthocyan, on the Zi Shu world, domestic market, extremely sells well, and development prospect is boundless.

But traditional purple potato cultivation exists the major defect of two aspects: the one, and potato shoot survival percent is low, and knot potato evening, the growth of cereal crop seedlings is inhomogeneous, and the fast size differences of potato is large; The 2nd, abuse chemical fertilizer and agricultural chemicals, or growing area soil is subject to industrial pollution serious, and the purple potato of producing is contaminated serious, heavy metals exceeding standard, quality declines, infringement people's physical and mental health.

Summary of the invention

goal of the invention: the present invention is directed to problems of the prior art, provide one neither contaminated, keep quality, improve again potato shoot survival percent, the growth of cereal crop seedlings is even, and potato is consistent soon, the purple potato culture technique method that output is high.

technical scheme: the cultivation method of a kind of organic purple potato of the present invention, specifically comprises the following steps:

1, milpa is selected: select without industry, free of contamination rural soil, soil layer is deep, quality is loose, physical features is mild, well-drained neutral sand loam plot;

2, whole ground: choose behind plot, carry out weeds cleaning in spring, then entirely cultivate and loosen the soil, deep plough 40 centimetres, hack is raked, ridging, 70～90 centimetres of row spacings, 35～40 centimetres of row spacings, ridge is high 35 centimetres, the surrounding ditch that begins to rehearse;

3, apply fertilizer to the subsoil: apply base fertilizer, every mu of organic fertilizer 2500～3000kg, is spread on fertilizer on the face of ridge equably, plough under in soil layer with hoe;

4, seed selection: select the kind that mouthfeel is good, pigment content is moderate, disease resistance good, potato type is attractive in appearance, select without scar, do soon potato seed without the potato of scab;

5, grow seedlings: the time fixes on when mid-February, temperature reached 15 degree left and right, first carry out seedbed, seed traverse is connected and come on seedbed, and 5 centimeters of left and right of line space, cover fine earth, soil is squirted with sprayer, build mulch film, topped day film, moisture-heat preservation, while growing to more than 20 centimeters to bud seedling, just can cut and be inserted into large field;

6, field-transplanting: the field-transplanting time, potato seedling was to be inserted as crosswise in annual late April to May, and the degree of depth is advisable to plant into three bud joints, and spacing is 18～22 centimetres, and density is every mu and inserts purple potato seedling 3500～4000 strains;

7, enhancement of field management, timely intertill and clean tillage: intertill 2-3 time, in conjunction with cultivation and banking support ridger, purple potato is afraid of accumulated water, must get rid of in time, when arid is serious, and timely trickle drought resisting;
