Spinach retention techniques

The spiny plant can be divided into the following four types: First, the absolute male, only open male flowers. The second is the male-dominant plant, which only has male flowers. Compared with the absolute male, the basal leaves are larger and the convulsions are later. The third is the female plant, which only has female flowers. The convulsions are later than the male plants. The fourth is the male and female plants, the same plant opens female flowers and male flowers, or opens "bisexual flowers", and the flowering period is close to that of female plants.

When it is found that some plants in the retained fields begin to twitch, absolute male plants and females with early twitches, as well as diseased plants, weak plants, hybrid plants, etc., should be removed as soon as possible, and then top dressing should be performed immediately to promote multiple branches of the plant. . In the future, a part of nutritional male plants should also be gradually removed. Usually, only 3-5 male and female plants that need to bloom at the same time per square meter can be left (for pollination purposes). After the female plants are seeded, all the male plants can be removed to promote seed development and maturation.

When most of the plant's stems and leaves have yellowed and the peel turned yellow-green, they can harvest the seedlings, stack them for 3-5 days, allow them to be “post cooked”, and then thresh and dry them for storage.

In the production of spinach hybrid seeds, it is generally advisable to use a 1:4 line planting method for the parent and the female, but it is necessary to pay attention to all the male and hermaphrodite strains in the mother line, as well as the female and hermaphrodite strains in the parent line. All clean and timely. Due to the complexity of the spinach plants, attention should be paid to mastering the techniques for seed retention.
