Embodiment

[0016] A kind of papaya breeding method is characterized in that, comprises the following steps:

[0017] A. the selection of papaya seedling single plant: the selected single plant grows vigorously, has no damage by disease and insect, and is good in variety, and the height of the selected single plant is controlled at 15cm;

[0018] B. Cultivate the making of soil: choose a petri dish, lay one deck coarse soil in the inside of this petri dish, the particle diameter of coarse soil is 150 orders, and the thickness of coarse soil layer is 4cm;

[0019] C. The planting of single plant: the single plant of the papaya seedling selected in step 1 is planted in the soil prepared in the step b, the root of single plant extends in the coarse soil layer, then inserts straw in the outside of single plant, The straw is inserted into the coarse soil layer, and the nitrogen fertilizer solution is injected through the straw. The nitrogen fertilizer content of the nitrogen fertilizer solutio...

Abstract

The invention discloses a papaya breeding method. The papaya breeding method comprises the following steps: selection of single plants of papaya seedlings, production of cultivation soil, planting ofthe single plants, and transplanting. The cultivated papaya plants have good disease resistance, and the plantability is stable; the cultivation time of young plants can be shortened; the germinationrate of papaya seeds is improved to 93%; germination and emergence are neat, and the quality of the seedlings is high; the problem of low germination rate or long germination time of papaya in normalconditions can be solved; and the papaya breeding method can improve the key technology of papaya seedling cultivation, provides a simple and practical method for mass propagation of papaya seedlings,and is wide in application range.

Description

technical field [0001] The invention relates to a papaya breeding method. Background technique [0002] Wild papaya is a woody vine of the genus Wild papaya in the family Akebia. Wildly distributed in Guangdong, Guangxi, Hong Kong, Hunan, Guizhou, Yunnan, Anhui, Zhejiang, Jiangxi, Fujian and other places. Growing in dense mountain forests, mountainside shrubs or sparse forests by valleys and streams at an altitude of 500-1300 meters. It has 5-7 palmate compound leaves, and the leaves are dark green and shiny. It is a vine with high ornamental value and can be used as a good material for vertical greening. In addition, the flowering period of wild papaya is from March to April, and the fruiting period is from June to October. The fruit is oblong, 7-10 cm long, and 3-5 cm in diameter. The pulp is edible and can be developed as a fruit variety. In addition, the whole plant of wild papaya can be used medicinally. According to folk records, it has the effects of relaxing tendo...
