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.

The invention relates to a method for improving the hybrid seed production yield of cabbages in facility, and belongs to the technical field of vegetable farming. The method includes the steps of seeding and seedling raising, land preparation and bedding, field planting of parent materials, bolting, bee depositing for fertilization, harvesting and the like. According to the method, seed productionof hybrid seeds of the cabbages in the facility is adopted, exotic other-cabbage pollen is effectively avoided, and the purity of the hybrid seeds is ensured; in the facility, black mulching film islaid, the growth of weeds can be effectively inhibited, the method also plays the roles of cooling and moisturizing the ground, and in this way, farm operation such as weeding and watering during beepollination can be reduced as far as possible; bees and mason bees are adopted to conduct matched pollination, and the mason bees are used for solving the problem that in a facility greenhouse, illumination is deficient, the temperature is high, the activity space is small, and bee pollination is deficient; the method not only can improve the yield of hybrid seed production, but also is low in cost, and reference is provided for facility seed production of other cruciferous crops.
