Embodiment Construction

[0022] The present invention will be further illustrated below by "an improved method for industrial transplantation of yam tissue culture seedlings and seed potato cultivation".

[0023] 1 Materials and methods

[0024] 1.1 Material: Test-tube seedling of Taizhou purple yam

[0025] 1.2 Test operation method

[0026] ① Seedling hardening: The culture cycle is 60-70 days, and the seedling height is 4-6 cm. The whole bottle is moved to the outdoor where the temperature difference from the culture room is within 5 ℃, and it is placed under scattered light for 5-6 days, and the bottle cap is opened for 1 day.

[0027] ② Seedbed preparation: Apply enough organic fertilizer (N+P 2 o 5 +K 2 O≥7%, organic matter≥30%, Nanjing Changhong Fertilizer Company) 1.5kg m 2 , deep plowing and raking, before transplanting, dig the seedbed with a shovel depth of soil (5-7cm), the width of the seedbed is 1m, break the soil and cover it with nutrient soil (organic cultivation substrate, the o...

Abstract

The invention discloses an improved method for factory transplanting Chinese yam tissue culture seedlings and cultivating seed yams and belongs to the technical field of agricultural production. According to the invention, the tissue culture seedlings are transplanted after seedling hardening; insulation planting boxes which is light transmitting and water conservation and combined with ventilation are adopted during transplanting living plants so that the yam tissue culture seedlings can be adapted to quick external environment change and the transplanting survival rate reaches 71.9%; and then through a series steps of strict seedbed management; finally, the ratio of tissue culture seed yams being 20g and above is 45.3%. According to the invention, by means of the insulation planting boxes for transplanting tissue culture seedlings, the yam tissue culture seedlings transplanting and seed yam reproduction are realized. The method of the invention is simple to operate and the produced seed yams have high quality and the reproduction of seed yam is fast and seed yams have less virus.

Description

technical field [0001] The invention relates to an improved method for factory transplanting of yam tissue culture seedlings and seed potato cultivation, and belongs to the technical field of agricultural production. Background technique [0002] Chinese yam (Dioscorea Opposita Thunb.) is a perennial herbaceous winding vine of the genus Dioscorea of ​​the family Dioscorea, and it is planted in various places in the north and south of my country. Because of its high nutritional value and medicinal value, it is an authentic medicinal material and traditional export commodity in my country, and its products sell well in Southeast Asia, Japan and other countries. Yam is usually propagated by tubers, which has a low reproduction coefficient and high production cost, and the long-term use of tubers for propagation leads to the accumulation of viruses and the degradation of the species, which seriously affects the improvement of quality and yield. [0003] Tissue culture can not o...
