Abstract

The invention discloses an inoculation method of tissue culture seedlings of potatoes. The inoculation method is characterized in that impact factors of the growth of the detoxified tissue culture seedlings of the potatoes are strictly controlled, and the tissue culture seedlings are subjected to integral cutting, dispersed tissue culture and cutting again after inoculation appliances, a culture room and an inoculation room are strictly disinfected and sterilized, so that the purposes of high speed, short cycle, low pollution, simple operation and low cost of the detoxified tissue culture and breeding of the potatoes are achieved.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, in particular to a method for inoculating potato tissue culture seedlings. Background technique [0002] With the continuous development of agricultural technology, potato detoxification technology has been widely used. The so-called virus-free means: cut out the growth cones of potato shoots at 0.2-0.3 mm, carry out tissue culture, cultivate virus-free test-tube seedlings, and then produce virus-free tubers. It has become the best method for preventing and controlling potato viruses and increasing potato yields. method. Combining shoot tip virus-free, tissue culture, and virus-free seed potato breeding to form a complete virus-free rapid propagation system can truly achieve the purpose of fast potato breeding and good quality. [0003] However, in the existing virus-free tissue culture technology, the investment in tissue culture is large and the economic benefit is low, which has se...
