Bee attractant and method for field seed production and bee pollination of soybean hybrids

Abstract

The invention discloses a bee attractant and a method for field seed production and pollination of soybean hybrids. The method comprises the following steps of: selecting a field which is suitable for the growth of soybeans, duly sowing the soybean hybrids, and intercropping male parents and female parents across ridges; selecting a required amount of healthy pollination swarm within 5 to 7 days before pollination, and transporting into the field of the soybeans at the early flowering stage of the soybeans; feeding attractant syrup within 1 hour before the bee attractant is sprayed everyday or every other day in the seed production field of the soybean hybrids which just blossom; spraying the bee attractant on leaves of hybrid soybean plants of the male parents and the female parents in 1 to 5 ridges of field across 1 to 5 ridges of field every 1 to 3 days so as to ensure that bees are attracted into the field and fall down to the leaves of the hybrid soybean plants to eat the syrup; spraying the attractant on two sides of stalks of the hybrid soybean plants to attract the bees to fall down to hybrid soybeans to collect so as to pollinate the hybrid soybeans; and stopping spraying the bee attractant in rainy days, and restoring the spray when the weather gets better so as to maintain the attractant which can meet the requirements in the field. The attractant is obtained by mixing a honeycomb liquid, a flower aroma imitation liquid and syrup in a proportion and diluting by using quantitative cold boiled water.

Description

technical field [0001] The invention relates to a bee attractant and a pollination method for soybean hybrid field production. Background technique [0002] Soybeans are self-pollinating plants that set pods normally without insect pollination. However, soybean hybrids must be artificially pollinated or insect pollinated to bear fruit. The soybean hybrids selected by the Jilin Academy of Agricultural Sciences for many years have a yield increase of more than 20% compared with ordinary soybeans, and some have increased yields by 30-50%. Soybean hybrids are composed of different varieties of soybean cytoplasmic male sterile lines as the female parent and different varieties of soybean restorer or maintainer lines as the male parent. However, cross-pollination of soybean is the bottleneck of the key technology of field seed production of soybean hybrids, which prevents large-scale promotion of soybean hybrids. Therefore solving soybean hybrid pollination has become the top pr...

Problems solved by technology

[0003]Bees are excellent pollinating insects, but bees do not like to interview soybean flowers, because soybean nectar and pollen are less, and the scent of flowers is low, which is not very attractive to bees. Therefore, Pollinating soybean hybrids the same way bees pollinate other crops does not work well
