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] Soybean hybrids were planted in the field according to 1 ridge male parent → 2 ridge female parent separated by ridges, a total of 11 male parent ridges and 20 female parent ridges were planted, each ridge length 150m.

Embodiment 2

[0030] With the embodiment 1, the difference is that on the male parent of the 1st ridge, the male parent of the 5th ridge, the male parent of the 10th ridge, every interval is 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 2 seedlings when they emerge. In this way, a certain number of nectar source plants are evenly distributed in the soybean field.

Embodiment 3

[0032] With the embodiment 1, the difference is that on the male parent of the 1st ridge, the male parent of the 5th ridge, the male parent of the 10th ridge, every interval is 30 meters (that is, at 0 meters, 30 meters, 60 meters, 90 meters, 120 meters, 150 meters at each point) plant the seeds of C. chinensis, and select 2 seedlings when the seedlings emerge. In this way, a certain number of nectar source plants are evenly distributed in the soybean field.

Abstract

The present invention relates to the technical field of crop pollination, in particular to a method for increasing the pollination rate of soybeans, by planting honey-pollination plants at the same flowering stage as soybeans among soybean crops, so that a certain number of honey-pollination plants are evenly distributed in the soybean field, by Therefore, during the flowering season of honey pollen source plants and soybeans, honey pollen source plants can attract a large number of flower-visiting insects to collect, and flower-visiting insects are looking for honey pollen sources in soybean fields. During the shuttle collection process, a large number of soybean flowers can be found, prompting The flower-visiting insects take the initiative to collect, and can stabilize the pollinators in the seed production field, continuously pollinate the hybrid seed production soybeans, and achieve the purpose of timely and effective pollination for the seed production soybeans.

Description

technical field [0001] The invention relates to the technical field of crop pollination, in particular to a method for improving the pollination rate of soybeans. Background technique [0002] Soybeans are self-pollinating plants. Commonly grown soybeans can set pods normally without pollination by insects. However, hybrid seed soybeans must be pollinated manually or by insects before they can bear fruit. Artificial pollination has problems such as high labor intensity, high labor cost and low efficiency. Insect pollination can not only increase yield, but also improve the quality of fruits and seeds, improve the vitality of offspring, and help improve the ecological environment and protect 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 little nectar and pollen, low floral scent, and are not attractive to flower-visiting insects. The method of u...
