Method for pollinating and producing seeds of rapes by osmia

Abstract

The invention relates to the field of pollination and seed production of rapes, in particular to a method for pollinating and producing seeds of the rapes by osmia. The osmia is Japanese osmiacornifrons; and the method comprises the following steps: 1-2 days before the flowering of the rapes, moving beehives with bee releasing openings on one side into a rape seed producing field or a seed producing shed, wherein the distance between the adjacent beehives is 20-30 m and the distances between the lower end surfaces of the beehives and the ground are 1.2 m; and when the flowering period of the rapes is finished, finishing the pollinating task of the osmia, finishing bee rearing and collecting the bees into the beehives. Compared with the traditional bee pollination and seed-production, the method for pollinating and producing the seeds of the rapes by the osmia, provided by the invention, has the advantages as follows: (1) the seed producing efficiency is high and seed purity is good; (2) time and labor are saved once for all; (3) times are consistent and the operation is easy; and (4) the method is used for both scientific research and production, not only is suitable for requirements of large-area seed production fields but also can preferably satisfy small-area seed production sheds, in particular hybrid seed productions in the small-area seed production sheds; and difficulty problems of crossing, more labors, low seed setting rate and the like are effectively solved.

Description

technical field [0001] The invention relates to the field of pollination and seed production of rapeseed, in particular to a method for pollination and seed production of rapeseed bees. Background technique [0002] At present, rapeseed pollination and seed production mainly adopt three auxiliary pollination methods: wind pollination, insect vector and artificial pollination. Wind media is affected by geography and climate, so it is generally not used as the main method. In production practice, two auxiliary methods, insect vector and artificial, are mainly used. The main insect vector is honeybees. It is reported that honeybees can improve pollination quality and yield by assisting pollination. However, honeybees have a large range of activities and a wide range of food, which has a certain impact on the purity of seed production. At the same time, it is greatly affected by the weather. In case of rainy weather easily lead to lower yields. For the small-area seed pro...
