A cultivation method for increasing yield of cabbage seed production

Abstract

The invention provides a cultivation method for increasing cabbage seed production yields. The cultivation method has the advantages that seed production fields are reasonably arranged according to plant height difference characteristics of two types cabbage parents, ridges are formed in the east-west directions in such a manner that the distance between each two corresponding groups is larger than the distance between each two corresponding ridges, each group comprises two corresponding ridges, the short parents are cultivated in the south ridge of each group, the tall parents are cultivated in the north ridge of each group, and accordingly natural lighting of the short parents can be guaranteed against being shielded; the parents can be in full-blossom periods simultaneously, the tall parents in the north cannot be affected by the short parents in the south, accordingly, the bee pollination efficiency can be improved, and the cabbage seed production yields can be greatly increased.

Description

technical field [0001] The invention relates to the technical field of cabbage seed production, in particular to a cultivation method for improving the yield of cabbage seed production. Background technique [0002] Cabbage (Brassica oleracea L.) is an annual or biennial herbaceous plant of the genus Brassica in the family Brassicaceae. It has become one of our important vegetables due to its strong adaptability and stress resistance, stable yield, and storage and transportation resistance. Improving the yield and quality of cabbage seed production has also become one of the problems that technicians in this field need to solve urgently. [0003] Measures to improve the yield and quality of cabbage seed production in the prior art mainly include: parental flowering adjustment, good water and fertilizer conditions, standardized management in the field, bee-assisted pollination during flowering, and phosphorus, potassium, boron, and zinc fertilizers sprayed on roots and leaves...

Problems solved by technology

[0004] However, the above-mentioned prior art has ignored the influence of the inconsistency of the plant height of the cultivated parental seedlings on the yield of seed production, and ignores the plant height difference when planting cabbage seeds, according to the male parent one ridge and the female parent one or more ridges. way of colonization

However, for parents whose plant heights differ by more than 30 cm, there will be differences in the utilization rate of light. The parents in the south will block the sunlight of the parents in the north, which will affect the pollination and growth of the parents in the north, thus affecting the production of plants.
