Transplanting and seedling exercising method of sugarcane detoxification and tissue culture rooting seedlings

Abstract

The invention discloses a transplanting and seedling exercising method of sugarcane detoxification and tissue culture rooting seedlings. The transplanting and seedling exercising method comprises thefollowing steps: A, selecting laterite or a mixed medium containing the laterite as a transplanting and seedling exercising medium of the sugarcane detoxification and tissue culture rooting seedlings;B, taking out the sugarcane detoxification and tissue culture rooting seedlings from a culture container and washing a culture medium on roots; C, dividing the washed sugarcane detoxification and tissue culture rooting seedlings into single plants and carrying out field planting on the transplanting and seedling exercising medium; D, keeping the moisture content of the transplanting and seedlingexercising medium to be 60 percent or more; E, shielding 30 percent or more than 30 percent of the sugarcane detoxification and tissue culture rooting seedlings from light; F, after one month, gradually entering a full-light seedling exercising phase when the survival rate of the sugarcane detoxification and tissue culture rooting seedlings reaches 95 percent; after two months, planting the sugarcane detoxification and tissue culture rooting seedlings in a large field. By adopting the transplanting and seedling exercising method disclosed by the invention, the problem that sugarcane tissue culture seedlings can survive after two times of transplanting is solved and 95 percent or more of the sugarcane tissue culture seedlings can survive by only one time of transplanting, so that the cost is reduced and the quality is improved; the economic benefits of a whole sugarcane industry are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of planting, and in particular relates to a method for transplanting and hardening seedlings of sugarcane detoxified tissue culture rooted seedlings. Background technique [0002] Sugarcane, (scientific name: Sanccharum officenarum L.) is a perennial tall solid herb of the genus Saccharum. Cane stems are thick and tall. Stems 3-5(-6) meters high. China Taiwan, Fujian, Guangdong, Hainan, Guangxi, Sichuan, Yunnan and other southern tropical regions are widely planted. Sugarcane is suitable for planting in places with fertile soil, sufficient sunlight, and large temperature differences between winter and summer. Sugar cane is a temperate and tropical crop that is used as a raw material for the manufacture of sugar and for ethanol as an energy substitute. There are more than 100 countries producing sugar cane in the world, and the largest sugar cane producing countries are Brazil, India and China. Sugarcane...

Problems solved by technology

It cannot solve the problem of one-time direct application to the production of pressed cane

[0004] There is also a limited number of virus-free stem seedlings. Only after three years of nursery expansion, can they be put into the production of pressed cane in the fourth year. The problem is that after three years of planting these two virus-free seedlings in the nursery, there are still two major problems. One is that the virus-free seedlings have re-susceptible to the disease, but the virus is lighter than that of the ones that have not been virus-free. shortened by more than one year; the second is still unable to get rid of the traditional cultivation mode of using cane stalks as seeds. Each acre of sugarcane needs to use about one ton of cane stalks as seeds, resulting in waste of cane stalks and very labor-intensive handling and sowing. Therefore, it is very necessary to develop a production technology of sugarcane detoxified tissue culture seedlings that can solve the above two problems and the field planting technology of this kind of tissue culture seedlings.
