Method for cultivating Chinese yam

Abstract

The invention discloses a method for cultivating Chinese yam, relates to a method for planting medicinal plants, belonging to the field of agricultural planting. The method comprises the following steps: a Chinese yam block is put in a biochemical incubator for accelerating germination until a bud eye germinated on the Chinese yam grows to be a budlet with the height being 0.2-0.4cm and the bud eye is completely germinated; a culture condition is that dark culture is implemented at 26-28 DEG C; after a tuber with the budlet is regularly disinfected, the tuber is transplanted onto an MS culture medium containing activated carbon to be cultured; the culture condition is that illumination lasts for 16 hours, the illumination intensity is 0.01-0.03mmol m<-2>.s<-1>, and the temperature is 26-28 DEG C; the dark culture lasts for 8 hours, and the temperature is 20-22 DEG C; the illumination and the dark culture are alternatively implemented. The method has the beneficial effects that the breaking of tuber dormancy is facilitated, and a certain amount of aseptic seedlings can be obtained by inducing, and therefore microtubers can be obtained by inducing; the survival rate of field transplanting of tubers achieves 100 percent; the method is not influenced by factors such as seasons and provides efficiently and fast good-quality Chinese yam.

Description

technical field [0001] The invention relates to a planting method of medicinal plants, which belongs to the field of agricultural planting, in particular to a planting method of Chinese yam. Background technique [0002] Dioscorea, commonly known as yam. Perennial herbaceous plant with vines, often purple, cylindrical root, opposite leaves, ovate or oval, milky white flowers, dioecious; light-loving, poor cold resistance. It should grow in well-drained, loose and fertile loam soil. Avoid flooding. The underground stem is cylindrical, and may also be deformed due to different growth geology, fleshy and thick. Root tubers contain starch and protein. Because of their rich nutrition, they have been regarded as a good quality and cheap tonic since ancient times. They can be used as staple food and vegetables. [0003] According to production surveys, the field tuber propagation coefficient of yam is generally about 10 times, and the degree of field variety mixing is as high a...

AI Technical Summary

Problems solved by technology

[0004] In terms of production, yam varieties are seriously mixed, resulting in a low degree of standardization of the cultivation technology system; for a long time, the asexual reproduction method of tuber breeding has been used for reproduction, and the reproduction coefficient is low, which seriously hinders the promotion of improved varieties.
