Detailed Explanation of Key Points of Vegetable Leaf Cuttage Cultivation Technology
Vegetable Leaf Cuttage Cultivation Technology
Using vegetable leaves for asexual propagation, applied to cabbage, Chinese cabbage, cauliflower, mustard, radish and rapeseed, etc., with a seedling survival rate as high as 80%-90%. Plants that survive cuttage have mild diseases, high seed yield, and stable genetic traits in the offspring. The leaf cuttage cultivation technology is as follows:
Making the seedbed: The seedbed requires high terrain, smooth drainage, good ventilation, a level bed surface, and loose and fertile bed soil, with a layer of 1-2 cm thick yellow sand spread on top, forming a sand-mud double-layer seedbed.
Selecting and retaining mother plants: Select excellent plants with the characteristics of this variety and free from pests and diseases as seed-retaining mother plants, use leaves from the middle part of the leaf head for cuttage, and the base of the leaf stalk must have axillary buds and some basal tissue. When the axillary buds have not yet sprouted, the cut should be kept away from the center of the base of the leaf stalk. Hormone treatment: Immerse the cut at the lower part of the stem of the cut leaf in an indoleacetic acid solution with a concentration of 2000 ppm for 2-3 seconds and then immediately remove it. Note that the axillary buds must not be immersed in the liquid, so as to avoid inhibiting sprouting.
Leaf cuttage: After the leaves are dipped in the hormone solution, they can be inserted into the seedbed. Keep the bed temperature at 15-25 degrees and the humidity at 70%-80%, avoid direct sunlight, and roots and sprouts will appear 7-8 days after sowing.
Transplanting and field planting: After the leaves take root and sprout, transplant them into nutrient pots, and plant them in the middle and late ten days of February of the following year, with field isolation for seed production, at a plant-row spacing of 54×60 cm. Field management is the same as for ordinary seed production.
