Matrix special for narcissus twin-bud-scale propagation

Abstract

The invention mainly relates to the field of planting technology, and discloses a special substrate for the double-scale propagation of narcissus, which is made of the following raw materials: corn stalks, bran, sheep dung, sweet potato vines, fallen leaves, sawdust, cocklebur, neem, vermiculite , perlite, sepiolite, and EM bacteria; rich in raw materials and uniform nutrition, the scale propagules of narcissus can be formed into balls in 40-45 days, and the ball forming rate can reach 98%, which obviously improves the double-scale propagation efficiency of narcissus; corn stalks, bran Skin, sweet potato vines, fallen leaves and sawdust are mixed and pulverized and fermented with EM bacteria to decompose the macromolecular nutrients in the raw materials into small molecular nutrients, promote the absorption and utilization of daffodil scales, enhance the cell vitality of scales, promote reproduction, and improve Ball forming rate: After adding sheep manure, cocklebur and neem seeds, the second fermentation will provide balanced nutrients, fully extract antibacterial substances, prevent scales from moldy and rot, improve the ball forming rate, and shorten the ball forming time.

Description

technical field [0001] The invention mainly relates to the technical field of planting, in particular to a special substrate for the double-scale propagation of narcissus. Background technique [0002] Narcissus, a traditional ornamental flower, is one of the top ten famous flowers in China; the propagation methods of narcissus are mainly lateral ball propagation, lateral bud propagation and double scale propagation. The traditional double scale propagation is to cut off the upper end of the scale and leave 2cm as propagation material. Then use a plastic bag to hold vermiculite with a water content of 50% or sand with a water content of 6%, put the propagation material into the bag, close the mouth of the bag, and place it in a dark place at a temperature of 20-28°C. After 2-3 months, small vegetative growths will grow. For bulbs, the ball forming rate can only reach 80-90%, which obviously reduces the reproductive efficiency of narcissus.
