Spinach seed retention technology
The sex types of spinach plants can be roughly divided into the following four types: one is an absolute male plant, and only male flowers are opened. The second is the male vegetative strain, which only opens male flowers. Compared with the absolute male plants, the basal leaves are larger and the convulsions are later. The third is a female plant, which only has female flowers, and the convulsions are later than the male plants. The fourth is monoecious, the same plant is opened with female flowers and male flowers, or "two sex flowers", the flowering period is close to the female plants. When some plants in the seeding field are found to start convulsing, the absolute male plants and the female plants with early twitching, as well as the diseased plants, weak plants, and hybrid plants should be removed early, and then the topdressing should be followed up to promote the multiple branches of the plants. . In the future, some nutrient male plants should be removed one after another. Usually, only 3-5 strains of male plants that bloom at the same time as female plants can be left per square meter (for pollination). After the female plants are seeded, all the male plants can be removed to promote seed development. When the stems and leaves of the plants are mostly yellow and the peel turns yellow-green, the seed plants can be harvested and stacked for 3-5 days to be "post-ripened", then threshed and dried for storage. For the production of spinach hybrid seeds, it is generally preferred to adopt a 1:4 line of parent and female, but it is necessary to pay attention to all the male and female strains in the female parent, as well as the female and amphoteric strains in the parental line. , all removed in time. Because the sex type of spinach plants is more complicated, it is necessary to pay attention to mastering the techniques of seed retention.
