The kohlrabi Cruciferae is a variant of mustard, and many people love to eat because of the rich flavor after processing. However, in recent years, due to the improper selection and retention of seeds, the rutabaga in many localities has been degraded such as small heads, leaves, bolting, and quality decline. Now introduce the causes of its degradation and rejuvenation methods. First, the cause of the degradation of the kohlrabi 1. Do not leave the seeds of the big plants. Some farmers often use small, weak, or short-term seedlings at the headland, small areas, or seedlings that are late for seedlings. They believe that these plants have no processing value and receive more seed. However, after several generations of heredity, the kohlrabi will become "toutou". 2. There are other cruciferous vegetables (especially mustard) near the planting site. Therefore, the offspring of the offspring that had not grown long heads and only long leaves had a "change of vegetables." 3. The seed collection time is too late. Some vegetable farmers only pursue a high seed production and germination rate, and they overlook the fact that kohlrabi seeds are too old and that their offsprings have been bred. Second, the rejuvenation of kohlrabi approach 1. Seed plant selection. Before the bolting of kohlrabi, the plants with large heads, short leaves, and few pests were selected and planted and planted. The phosphorus and potassium fertilizers were applied at a later stage and less nitrogen was applied to prevent the occurrence of soft rot. 2. Avoid variation in insect pollination. If there are cruciferous vegetables in the vicinity of the flowering at the same time, a net cover is needed to prevent insect pollination. 3. Timely harvest. The flowering period of kohlrabi is very long, and the flowers that are opened later only consume nutrients. When the seeds in the middle and lower part of the flowering branch are slightly hard, the unopened flowers on the top of the flowering branch should be removed, so that the nutrients can be concentrated for the development of the lower seed. After about 10 days, the branches were retracted, hung in a ventilated place for several days, dried in the hot sun, and then threshed and stored.
