Method for raising seedlings of American red maple red sunset by cutting

Abstract

The invention relates to a method for raising seedlings of American red maple red sunset by cutting, which comprises three steps of preparing matrix, processing branch and cutting, wherein the matrix is selected from perlite, vermiculite, turfy soil and rough river sand, potassium permanganate and carbendazim are used for sterilizing, then the growth regulator immersed branch is cut according to a certain line-spacing, plant spacing and depth, the cut branch is kept in a certain temperature and humidity and sterilization for the matrix and topdressing of a foliage fertilizer are performed on time. After the perfect cooperation of the above steps, the rooting rate of the branch is more than 97%, and compared with the prior art, the survival rate is increased by 15%, therefore, the defects in seeding breeding and the present cutting breeding technology are overcome, and the income of the grower is improved.

Problems solved by technology

When planting the American red maple, it can be planted by spring or autumn sowing. The spring sowing needs to go through steps such as soaking, sand storage, sowing, water and fertilizer treatment, etc., and the seedlings grow slowly after unearthed and have poor resistance. Careful care should be taken. Scores can be carried out in two years; among them, the germination rate of autumn sowing is generally not high, so growers generally do not use autumn sowing unless the seedlings are very nervous. Careful care, so some farmers buy branches for cutting propagation, but due to the processing of branches and immature cutting technology, the rooting rate and survival rate of branches are not high
