Method for improving hybrid seed production yield and quality of common head cabbages

Abstract

The invention relates to a method for improving hybrid seed production yield and quality of common head cabbages, which belongs to the technical field of plant cultivation. The method comprises the following steps of: seeding and raising seedlings from a female parent and a male parent in early August, and seeding English wallflower in mid-to-late September; planting the raised seedlings of the female parent and the male parent of the common head cabbages in a hybrid seed production field of the common head cabbages in mid-to-late September, wherein English wallflower planting points are reserved in each seed production field; planting young English wallflower seedlings in the field planting points reserved in the hybrid seed production field of the common head cabbages in later October; applying aqueous solution of honey with the concentration of 0.5-1 percent to foliages for 2-3 times during a flowering period of common head cabbage plants, putting about 60000 bees in two boxes for auxiliary pollination in each mu during natural pollination; and harvesting and timely airing and threshing the common head cabbages when common head cabbage pods are yellowed and seeds are browned. The honey source crops are reasonably planted in the seed production field, and the honey mixed solution is sprayed during the flowering period, so that the bees can be effectively attracted to perform pollination, the cross pollination probability obviously increases, and the seed production yield and quality of the common head cabbages are obviously improved.

Description

technical field [0001] The invention relates to a breeding method of cabbage, in particular to a method for improving the yield and quality of hybrid seed production of cabbage, belonging to the technical field of plant cultivation. Background technique [0002] Heading cabbage (Brassica oleacea L.var.cap itata L.) is a variety of Brassica genus Brassica, also known as cabbage, cabbage, cabbage, cabbage, cabbage, lotus white, etc. It is grown in China and many countries in the world Main vegetable crops. Due to its obvious heterosis, almost all the excellent cabbage varieties used in production are first-generation hybrids, and there are two main ways to produce the first-generation hybrids of cabbage: the use of self-incompatible lines for seed production and the use of male sterile lines for seed production . In order to improve the yield and quality of cabbage hybrid seeds, through continuous research and conclusion, people have realized that harvesting high-quality and...

[0004] Although the flower color of head cabbage is brighter when it blooms, the nectary glands are not developed enough (there are large differences between different varieties), especially the flowering period of head cabbage, which coincides with the blooming period of many other plants, and many of these plants are more sensitive to bees. Alluring variety, so it will attract most bees away, even if the cabbage farming bees will not help
