A method for directional breeding of lotus hybrid f1 generation by bee pollination

Abstract

The invention discloses a kind of bee vector pollination directed cultivation lotus hybrid F 1 The method of generation, comprising: in the isolated net room that planted with lotus male parent and lotus female parent, collects the wasp eggs of the wasp at low temperature, when pollination, heats up the egg of wasp and hatches the egg of the wasp to pollinate, and then the wasp lays eggs , and continue to store the obtained wasp eggs at low temperature, and then in the next pollination period, hatch to obtain the wasp, and repeat the cycle operation. In the present invention, during the pollination period, the wasp hatches and is pollinated by the wasp, and the wasp can subsequently lay eggs, and the eggs will continue to be stored at low temperature. When the next pollination period is reached, the eggs will be hatched to obtain adults, which can be obtained during the pollination period. Carry out pollination, repeat cycle hatching and obtain wall bee, maintain sufficient number of wall bee to pollinate during pollination period. In addition, the flowers of the lotus female parent can be bloomed in sequence, and only one mature flower is kept at the same period, so as to avoid the self-pollination of the lotus female parent and affect the pollination effect of the lotus male parent, ensure that the pollination is hybrid pollination, and increase the probability of hybrid pollination.

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...

Problems solved by technology

Although this method can ensure the existence of bees in the insect net and pollination by bees, it is difficult to guarantee the survival of bees, and it cannot ensure that there must be bees during pollination, which will affect pollination
