Problems solved by technology

At present, the seedling raising method of purple sweet potato mostly adopts soil cultivation and seedling cultivation, which is greatly affected by the temperature environment, has certain seasonality, low seedling yield, difficult control of conditions, uneven emergence, and is not conducive to unified management. Therefore, a kind of High-efficiency seedling raising method of purple sweet potato, improving the yield and quality of seedling raising, and expanding the planting scale of purple sweet potato
At present, purple sw

Embodiment 1

[0038] A kind of seedling raising method of purple sweet potato, it specifically comprises the following steps:

[0039] 1 Sterilization: Collect the young budding stems of purple sweet potato from the field, remove the leaves and excess petioles, trim them into 0.5cm-long stems, wash off the dust and soil on the surface with a brush under running water, and then use Sterilize with ascorbic acid solution, wash with washing powder solution, rinse with running water for 30 minutes; sterilize with alcohol, rinse with sterile water twice, then sterilize with mercury chloride solution, rinse with sterile water twice for later use; Bacteria can kill the harmful microorganisms carried by the shoot tip of purple potato, avoid introducing harmful microorganisms into the culture medium to cause pollution, and at the same time prevent the absorption and utilization of the culture medium by microorganisms, and provide sufficient nutrients for the shoot tip cells for their differentiation; ...

Embodiment 2

[0053] A method for raising seedlings of purple sweet potato, comprising:

[0054] a) Get the young and tender stem section of purple potato with buds and trim it into small sections, then carry out sterilization treatment;

[0055] b) the subsection of step a) is propagated and cultivated in a proliferation medium containing powdery activated carbon to obtain seedlings;

[0056] c) the seedlings of step b) are cultivated in the rooting medium to obtain the increased seedlings of purple sweet potato;

[0057] d) The purple sweet potato seedlings are sterilized after hardening and transplanted.

[0058] Wherein, the proliferation medium is MS medium containing 8g / L sucrose, 15mg / L benzylquinine chloride, 0.4g / L ethanol, and 0.12g / L oxytetracycline.

[0059] In the method of the present invention, firstly, the young purple sweet potato stem section with buds collected from the field is trimmed, and after being sterilized with ascorbic acid solution, alcohol, and mercuric chlorid...

Embodiment 3

[0076] Example 3 is basically the same as Example 2, except that in Example 3, the proliferation medium does not contain benzylquinine chloride.

Abstract

The invention provides a seedling culturing method for purple sweet potatoes, and belongs to the field of purple sweet potatoes. The seedling culturing method includes the steps that a, purple sweet potato tender stem segments with shoots are trimmed into small segments and then sterilized; b, the small segments in the step a are subjected to proliferation culturing in a proliferation culture medium containing active carbon powder, so that seedlings are obtained; c, the seedlings in the step b are cultured in a rooting culture medium, so that purple sweet potato proliferation culturing seedlings are obtained; d, after being hardened, the purple sweet potato proliferation culturing seedlings are sterilized and transplanted. The seedling culturing method has the advantages that during proliferation culturing, the active carbon is added to reduce the browning rate of stem tips, callus induction and differentiation are easy, the secretion and activity for growth of related protein enzymeson the stem tips are improved, the seedlings have robust activity, during rooting culturing, auxin type substances are not prone to being degraded by light and can reach acting positions through complexing and decomplexing to realize the effect of adjusting growth, finally, root systems of the seedlings are sturdy and dense, and the survival rate of transplantation can reach 100%. The seedling culturing method for purple sweet potatoes is good in culturing effect and high in survival rate of transplanting.

Description

technical field [0001] The invention belongs to the technical field of purple sweet potato cultivation, and in particular relates to a purple sweet potato seedling raising method. Background technique [0002] Purple potato (Ipomoea batatas (L.) Poir. Convolvulaceae Convolvulaceae sweet potato genus) is also called black potato, and the potato meat is purple to dark purple. In addition to the nutrients of ordinary sweet potatoes, it is also rich in selenium and anthocyanins, and purple potatoes are one of the main raw materials for anthocyanins. Purple sweet potato likes a warm climate environment, and the suitable growth temperature for stems and leaves is 18-25°C, and stops growing when the temperature is lower than 15°C. The optimum growth temperature of tubers is 22-24°C, and the growth will stop when the ground temperature is lower than 20°C. [0003] In the process of introduction, propagation and production of new varieties or lines of purple sweet potato, vegetativ...
