Ilex latifolia seedling cultivation method

Abstract

The invention relates to the technical field of ilex seedling plantation and management, in particular to ilex latifolia seedling cultivation method. The method is characterized by including the steps: seed treatment: soaking seeds in water at the temperature of 40 DEG C for 12 hours, standing for 24 hours at the low temperature of 5 DEG C, soaking in water at the temperature of 40 DEG C for 10 hours, soaking the seeds in 0.3% potassium permanganate solution for 20-30 minutes, taking out, soaking in clean water for 8-10 hours, and placing in a sand bed for accelerating germination, wherein seeds sprout successively after about 2.5-3.5 mouths; transplantation of bud seedlings; fertilization; winter protection: additionally spreading potash fertilizers after autumn to seedling lignification, properly shortening shading time in the later period, gradually removing sunshade nets from the beginning of September to increase illumination, and erecting tunnels and mulching to prevent cold and keep a full stand of seedlings before extreme temperature in winter comes. The ilex latifolia seedling cultivation method has the advantages of simplicity in operation, short seedling cultivation period, high sprouting rate, quickness in sprouting and improvement of economic benefit of ilex latifolia seedling cultivation.

Problems solved by technology

Most of the existing methods of raising seedlings of Ilex chinensis adopt the method of sowing and raising seedlings. Because the dormancy period is as long as 3 years, the seeds need to be stored in wet sand for 1-1.5 years. This will lead to a very long time period for sowing and raising seedlings. The time is very long and the germination rate is also very low
