Method for increasing flower visiting rate of bees for hybrid soybean seed production

Abstract

The invention relates to the field of pollination of crops, in particular to an effective method for increasing the flower visiting rate of bees. The flower visiting frequency and the number of flowers visited by the bees are increased by combining bee colony control and spraying of an attractant on plants. The method comprises steps as follows: a hybrid soybean field adopting bee pollination is selected; the structure of a bee colony is adjusted; the bee colony for pollination is transported to the soybean field, and the selected bee colony for pollination is transported to the hybrid soybean seed production field in the early stage of flowering of the soybeans; the attractant to be sprayed to the plants is prepared from linalool, benzyl alcohol, ocimene, geraniol, nerol, mushroom alcohol and 2-heptanone. The bee colony is released in the pollination field after being prepared, and the attractant is sprayed on flowers of crops in the flowering period of the crops to attract the bees to visit the flowers. The biological characteristic that pollen and smell are taken as one of approaches to food-source orientation of bee larva is utilized, a large quantity of bees are attracted, the number of the flowers visited by the bees and the natural pollination rate are increased, the yield of the crops is increased, and the method has the characteristics that the method is scientific, simple, convenient and easy to operate, low in cost and remarkable in effect and materials are low in price and easy to obtain.

Description

technical field [0001] The invention relates to the field of crop pollination, in particular to an effective method for improving honeybee visits to flowers and improving crop pollination effects. Background technique [0002] Honeybee insects have unique morphological physiological structure and biological characteristics, and are the most ideal pollinating insects for crops. Many economically developed countries in the world attach great importance to using bees to pollinate crops to improve the ecological environment of farmland and ensure high-quality and high-yield crops. The pollination of crops by bees can not only increase the yield, but also improve the quality of fruits and seeds and the vitality of offspring, which is conducive to the improvement of the ecological environment and the protection of people's health. It has been affirmed that bees pollinate crops and fruits and vegetables, and improve their fruit setting rate and quality. However, when bees pollina...

Problems solved by technology

However, soybean hybrids must be artificially pollinated or pollinated by insects to bear fruit. At present, artificial pollination is used to solve the pollination problem, which has problems such as high labor intensity, high labor cost, and low efficiency.

Although bees are excellent pollinating insects, bees do not like to interview soybean flowers, because soybean nectar and pollen are less, and the fragrance of flowers is low, which is not very attractive to bees. Pollination, the effect is not ideal

[0004] In short, soybean cross-pollination is a bottleneck that plagues the key technology of soybean hybrid field seed production, preventing soybean hybrids from being widely promoted
