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.
