A kind of papaya high-pressure propagation method

Abstract

The invention relates to the technical field of plant propagation, in particular to a method for high-pressure propagation of papaya. It includes three steps: preparation for high-pressure measures, implementation of high-pressure measures, and treatment of high-pressure seedlings. The specific implementation is to select an adult hermaphrodite papaya with good performance in the field as the female parent tree, and perform high-pressure directly on the lower end of the lowest fruiting part of the female parent plant or place the papaya Cut off the upper part of the plant, induce multiple side branches to sprout from the lower part of the cut, and then apply high pressure on the side branches. Coconut bran is used as the rooting substrate. After the adventitious roots grow out after high pressure, the plants that have succeeded in high pressure can be cut off from the mother tree, moved into a nutrition bag for artificial planting, and transplanted to the field when the root system is further developed and new leaves are born. The high-pressure propagation method of papaya of the present invention has simple operation process, short required time, and its rooting rate and survival rate are both over 90%, which is a simple and efficient asexual propagation method of papaya.

Description

technical field [0001] The invention relates to the technical field of plant propagation, in particular to a method for high-pressure propagation of papaya. Background technique [0002] Papaya (Carica Papaya) is a herbaceous fruit tree native to tropical America. It is now widely cultivated in tropical and subtropical regions of the world. The growth period of papaya is short, and it can be harvested in the same year when planted in the same year, and the yield is high. Papaya has a wide range of uses. In addition to being used as fruits and vegetables, papaya enzymes can also be used in food processing and other fields. [0003] The propagation of papaya can adopt the sexual propagation of seeds and the asexual propagation of cuttings, grafting and tissue culture. Papaya has three different plant sexes: male plant, female plant and hermaphrodite plant. Among them, the male strains cannot bear fruit, and the fruit shape and quality of the fruits produced by the female s...
