Artificial hybridization, breeding and pollination method of moringa oleifera

Abstract

The invention relates to a hybridization, breeding and artificial pollination method of moringa oleifera. The method comprises the steps that male and female parents are selected, dwarf pruning is carried out on a female parent tree body, and flower thinning is carried out in the full-bloom stage for removing bloomed simple flowers and retaining buds with consistent states; when the buds turn white and bulge out in the day before the female parent blooms, castration and marking are carried out, and then whole plant netting is carried out on the female parent to prevent the interference of foreign pollen carried by pollinating insects; when the buds turn white and bulge out in the day before the male parent blooms, marking is carried out, then whole plant netting is carried out on the male parent to prevent foreign pollen carried by pollinating insects from contaminating target pollen; in the third day of blooming of the female parent, male parent pollen in the first day of blooming is given, a net is disassembled after a week of pollination, and pods obtained through hybridization are harvested in time. By adopting the hybridization, breeding and artificial pollination method, the effective pollination of the moringa oleifera can be ensured, the pod setting percentage of the moringa oleifera is increased, the variety of the moringa oleifera is improved, the artificial hybridization and breeding efficiency is improved, and the development of a moringa oleifera breeding technology in China is accelerated.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a pollination method for artificial cross breeding of Moringa oleifera. Background technique [0002] Moringas p p ., also known as drumstick tree and miracle tree, is a miraculous tropical and subtropical multifunctional plant with a long history of edible, rich and comprehensive nutrition. The best sources of plant protein, vitamins, folic acid, pantothenic acid, calcium, iron, selenium and other nutrients have been found, which have unique economic value and health benefits. There are "miracle tree" (miracle tree) and "mother's best" abroad. Friends" (mother's bestfriend) and "nature's medicine cabinet" (nature's medicine cabinet), while in Taiwan, China, they are known as "21st century bodyguards". As early as hundreds of years ago, there were records of eating or using moringa. In the 19th century, Europe imported moringa oil (called Ben oil) from India for making per...

AI Technical Summary

Problems solved by technology

[0006] Moringa is a single family and a single genus. At present, there is no report on artificial pollination technology of Moringa

Artificial pollination is difficult to achieve mainly due to the following reasons: (1) Moringa has a large amount of flowers, the flower stalk is short, and it is easy to fall off. Artificial bagging is easy to break the flowers and cause a large number of flowers to fall; (2) Moringa The flowering time is short, there is a time difference between the maturity of stamens and pistils, the amount of pollen of stamens is small, and it is difficult to collect, and the pollination time of pistil stigma is short; No fruit; (4) The full flowering period of Moringa is just the period with the largest precipitation in the south, and there are less insect activities, resulting in a low fruit setting rate
