Papaya tissue culture seedling transplanting method

Abstract

The invention belongs to the technical field of fruit tree growing, and particularly relates to a papaya tissue culture seedling transplanting method. The method comprises the steps of 1, taking well cultured papaya tissue culture seedlings out of a culture vessel by clumps, placing the papaya tissue culture seedlings in a container with the bottom and periphery hollowed out, and determining the number of the papaya tissue culture seedlings arranged in the container according to the size of the container; 2, soaking the roots of the papaya tissue culture seedlings in the container completely in disinfectant for 5-10 min, and then taking the papaya tissue culture seedlings out; 3, planting the papaya tissue culture seedlings which are taken out in a culture medium by clumps. By the adoption of the method, the transplantation survival rate of the papaya tissue culture seedlings can be increased, and growth recovery of the papaya tissue culture seedlings is quick; the formula of the disinfectant is reasonable, the possibility of generation of damping-off pathogenic bacteria in the transplanting period of the papaya tissue culture seedlings can be reduced, and growth of roots of the transplanted papaya tissue culture seedlings is facilitated; the adopted culture medium has air permeability and a water retention function, so that survival and growth of the papaya tissue culture seedlings are facilitated.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, in particular to a method for transplanting papaya tissue culture seedlings. Background technique [0002] Papaya (Caricapapaya L.), also known as papaya, milk melon, longevity fruit, is a tropical and subtropical evergreen cork large perennial herb, evergreen cork small tree, up to 8-10 meters, with latex; stems are not branched or Sometimes branched at the damaged site, with helically arranged stipules. The fruit grows on a tree and looks like a melon, hence the name papaya. The milk of papaya is the main ingredient for making loose meat powder. [0003] Papaya is distributed in tropical and subtropical regions of the world. Native to southern Mexico and adjacent central America, it is now mainly distributed in Malaysia, the Philippines, Thailand, Vietnam, Myanmar, Indonesia, India and Sri Lanka in Southeast Asia; Central and South America, the West Indies, Florida, Hawaii, an...

Problems solved by technology

During the transplanting process of papaya tissue culture seedlings, due to transplanting from sterile medium to bacteria-carrying planting substrate, because the substrate is not clean, bacteria are carried to varying degrees, which can easily cause root pathogens to cause rotten roots and seedlings and reduce the growth rate of the group. The transplanting survival rate of cultivated seedlings; the traditional method needs to wash the seedlings to remove the medium before transplanting, which will cause most of the root damage and cause abnormal root system function of the plant, which will affect the growth of papaya tissue culture seedlings; the traditional cultivation medium generally uses soil, Its air permeability and water retention are poor, and it is difficult to provide appropriate water and nutrition for papaya tissue culture seedlings, thereby affecting the growth of papaya tissue culture seedlings
