Embodiment 1

[0026] A kind of bee vector pollination directed cultivation lotus hybrid F 1 method, including the following steps:

[0027] (1) Choose an insect-proof mesh of more than 100 meshes to build an isolation mesh room;

[0028] (2) the net room is divided into the male parent's planting area and the female parent's planting area, and the distance between the male parent's planting area and the female parent's planting area is 100cm;

[0029] (3) 5 lotus male parents are planted in the male parent planting area in the net room, wherein the plant spacing of the lotus male parent is 30cm, and 1 lotus female parent is planted in the female parent planting area; wherein, the male parent planting area and the female parent planting area Both are set as the existing conventional lotus planting environment, and the planting methods of the lotus male parent and the lotus female parent are also planted using the existing conventional planting method; , to remove the remaining flowers, tha...

Abstract

The invention discloses a method for directive breeding of a lotus hybrid F1 generation by bee pollination. The method comprises the following steps: Osmia eggs of Osmia are collected and stored at low temperature in an isolation net chamber where a locus male parent and a lotus female parent are planted, during pollination, the Osmia eggs are heated and hatched to produce Osmia for pollination, Osmia lays eggs later, the obtained Osmia eggs are collected and stored continuously at low temperature and then hatched to obtain Osmia in a next pollination period, and the operation is repeatedly circulated. The Osmia is hatched in the pollination period, pollination is carried out by the Osmia, the Osmia can lay eggs later, the laid eggs are collected and stored continuously at low temperatureand hatched to obtain adults, pollination can be carried out in the pollination period, the Osmia is obtained by repeated circulating hatching, and sufficient Osmia is kept in the pollination period for pollination. Besides, flowers of the lotus female parent can bloom sequentially, only one flower in a mature period is reserved in a same period, effects of self-pollination of the lotus female parent on the pollination effect of the lotus male parent are avoided, hybrid pollination is ensured, and the probability of hybrid pollination is increased.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a bee vector pollination directional cultivation lotus hybrid F 1 method of generation. Background technique [0002] The lotus is a perennial aquatic herb with beautiful flowers and leaves, rich colors, long flowering period, and high ornamental value; the root of the lotus can absorb toxic substances such as lead, mercury, and phenol in the water, and is a rare water purification plant; Has medicinal value. [0003] The lotus pollen and the stigma of the same flower of lotus have a time difference in the maturity period, and the same flower self-pollination cannot be performed. If pollination is required, cross-pollination is usually used. The method of alienation pollination includes self-pollination and hybridization. The method is usually based on hybridization, and requires external media, such as natural pollination methods such as wind and inse...
