Cultivation method of virus-free seedlings of mangos

Abstract

Provided is a cultivation method of virus-free seedlings of mangos.The cultivation method concretely comprises following steps of: firstly, setting up an introduction observation garden, an experimental garden, a foundation stock field, a female plant garden and an exhibition garden; secondarily, selecting original female plant material to enter the introduction observation garden, the experimental garden, the foundation stock field, the female plant garden and the exhibition garden; thirdly, continuously spot-checking infection conditions of viral diseases of nursery stocks by means of the observation garden, the experimental garden, the foundation stock field, the female plant garden and the exhibition garden; and lastly, confirming that no mango in the female plant garden and the exhibition garden is infected with viral diseases and then accelerating propagation of nursery stocks. The cultivation method of virus-free seedlings of mangos has following beneficial effects: through multi-level observation of characteristics of nursery stocks, mass propagation can be carried out in order to ensure that nursery stocks are pure and virus-free and also to make sure that quality and yield of mangos are steadily improved; and by application of the cultivation method, high-quality nursery stocks of mangos can be favorably reproduced in a factory-like, large-scale and intensive mode.

Description

technical field [0001] The invention belongs to the new technology field of plant seedling propagation, and in particular relates to a method for cultivating virus-free mango seedlings. technical background [0002] Mango is one of the most widely distributed fruit trees in the world. It is native to India and Malaysia. India has the longest cultivation history and the largest output, accounting for 80% of the world's output. Mangoes are grown in Taiwan, Guangdong, Guangxi, Hainan and southern Fujian, and southern, southeastern and southwestern Yunnan. [0003] The climate in Guangdong, Guangxi, and southern Fujian in my country is most suitable for cultivating and multiplying mango seedlings. Guangxi is the province with the highest yield, with an annual output of more than 320 million plants per year. [0004] Traditional mango seedling breeding methods are: [0005] (1) Seed kernel processing: select relatively large seed kernels, after cooling and drying, carefully re...

Problems solved by technology

[0008] Since mango is a tropical fruit, continuous cropping is very easy to be infected by viruses, which in turn reduces yield and quality
