Problems solved by technology

However, soybeans have less nectar and pollen, low flower fragrance, and are not very attractive to flower-visiting insects. The method of using flower-visiting insects to pollinate other crops to pollinate soybean hybrids is not ideal, and the pollination effect is poor. low, thus affecting the effect of seed production
Therefore, the problem of high-efficiency pollination in soybean hybrid seed production is a bottleneck that plagues the key technology of soybean hybrid field seed production, which prevents soybean hybrids from being widely promoted and hinders the industrialization process of hybrid soybeans

Embodiment 1

[0028] Field seed production of soybean hybrids is carried out according to 1 ridge male → 2 female ridges with interplanting. A total of 11 male ridges and 20 female ridges are planted, and the length of each ridge is 150 m.

Embodiment 2

[0030] With embodiment 1, difference is, respectively on the male parent of the 1st ridge, the male parent of the 5th ridge, and the male parent of the 10th ridge every interval of 30 meters (that is, at 0 meters, 30 meters, 60 meters, 90 meters, 120 meters, 150 meters at each point) plant motherwort seeds, and choose to stay 2 seedlings when emerging. In this way, a certain number of honey powder source plants are evenly distributed in the seed production soybean field.

Embodiment 3

[0032] With embodiment 1, difference is, respectively on the male parent of the 1st ridge, the male parent of the 5th ridge, and the male parent of the 10th ridge every interval of 30 meters (that is, at 0 meters, 30 meters, 60 meters, 90 meters, 120 meters, 150 meters at each point) plant sweet-scented osmanthus seeds, and choose to stay 2 seedlings when emerging. In this way, a certain number of honey powder source plants are evenly distributed in the seed production soybean field.

Abstract

The invention relates to the technical field of crop pollination, in particular to a method for increasing the pollination rate of soybeans. According to the method, nectar and pollen plants with the same flowering phase as soybeans are planted between soybean crops, a certain number of the nectar and pollen plants are evenly distributed in a soybean field, so that in the flowering season of the nectar and pollen plants and the soybeans, the nectar and pollen plants can attract a large number of flower visiting insects to come for collection, the flower visiting insects seek nectar and pollen in the soybean field, can find a large number of soybean flowers in a shuttling collection process and are promoted to actively come for collection, moreover, pollination insects can be stabilized in a seed production field, pollination is continuously conducted on hybrid seed production soybeans, and therefore, the purpose of timely and effectively pollinating the seed production soybeans is achieved.

Description

technical field [0001] The invention relates to the technical field of crop pollination, in particular to a method for improving soybean pollination rate. Background technique [0002] Soybeans are self-pollinating plants, and commonly grown soybeans can set pods normally without being pollinated by insects. However, soybeans for hybrid seed production must be artificially pollinated or pollinated by insects to bear fruit, and artificial pollination has problems such as high labor intensity, high labor cost, and low efficiency. Insect pollination 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. Flower-visiting insects pollinate crops and fruits and vegetables, and have been affirmed in improving their fruit set rate and quality. However, soybeans have less nectar and pollen, low flower fragrance, and are ...
