Cultivation method of red heart red dragon fruit

Abstract

The invention provides a method for cultivating red-pulp hylocereus polyrhizus. The method includes the steps that anthracnose-free hybridized target single plants with the features that the numbers of borne fruits are large in successive years, the weight of single fruit bodies is 400 g or above, the fruit bodies are elliptic, fresh, sweet, elegantly fragrant and good in taste, pulp is bright and rosy, and branches are thick and solid are marked; particularly, branches of the plants in which pistil protrudes out of stamen thrums by 1 cm or less are preferentially and independently collected, sterilized, detoxified and subjected to seedling growing, seedlings are transplanted to land, large-area fruit tree management is carried out, and commercial hylocereus polyrhizus is formed. After three-year intensive-culturing test application, the yield can be continuously high, and the fruits are large and are stabilized to be 0.4-0.5 kg or above; compared with the earlier stage, the fruits are fresher, sweeter and more elegantly fragrant, the shapes of the fruits are not varied and kept elliptic, the content of fructose is about 6.8%, the content of glucose is about 4.2%, and the content of haematochrome is about 4%; other excellent substance characters such as nutrients, the health caring function and the medicine function are not changed, the characters of the original male parent are kept, the hybrid vigor is remarkably expressed, the survival rate is 97% or above, the fruit bearing rate is 95% or above, and the red-pulp rate is 95% or above.

Description

technical field [0001] The invention belongs to the field of cultivation of economic crops, and in particular relates to a cultivation method of red heart red dragon fruit. Background technique [0002] With the development of the economy and the acceleration of the pace of life, consumers have a deeper understanding of healthy life. Healthy, environmentally friendly and healthy fruits are more and more needed by people. Fruits that are polluted, have excessive radiation and pesticide residues threaten people's health. The inventor has been committed to the research of red dragon fruit. Red dragon fruit, also known as giant dragon fruit, is different from red-skinned and white-fleshed dragon fruit and sesame fruit. It comes from Mexico in Central America and is a cactus triangular prism. It is one of more than ten varieties of honey family. It is a vine perennial succulent plant. The inventor used the hybridization theory to combine the local wild and wild male sterile germ...
