Method for quickly rooting in ormosia hosie cuttage process

Abstract

The invention discloses a method for quickly rooting in the ormosia hosie cuttage process. The method includes the steps of cutting selection, cutting band girdle treatment, seedling culturing matrix matching, seedling culturing bed building, and cuttage temperature preservation management and protection, wherein the cuttage temperature preservation management and protection is achieved through a method that cuttings are cut on the position 2 cm to 3 cm below the cutting band girdle position where callus is formed, the cutting blades and lateral branches are removed totally, three to six sprouts are left, the scissoring openings of the top ends of the cuttings are flushed with one another and are coated with Vaseline, the cutting roots are immersed in rooting power solutions or rooting agents, the matrix is inserted, a small plastic film arch shed is built, a shading net with the shading coefficient ranging from 60% to 75% covers the small plastic film arch shed, the temperature of the matrix is controlled within 23 DEG C to 28 DEG C, and the water content of the matrix is remained within 60% to 70%. Root systems are formed 15 days to 20 days after cuttage, counted from cuttage time, the cycle of seedling culturing is shortened by 35 days to 100 days, counted from band girdle pre-treatment, the cycle of seedling culturing is shortened by 20 days to 80 days, the actual survival rate after cuttage reaches 90%, the cycle of seedling culturing is shortened greatly, and production cost is saved.

Description

technical field [0001] The invention belongs to the technical field of plant seed breeding, and in particular relates to a method for cutting and propagating red bean trees. Background technique [0002] Red bean tree (Ormosia hosieiHemsl.et Wils.) is a second-class national key protected wild plant. Its material is heavy and its pattern is unique. It belongs to mahogany wood. It is a special economic and high-grade material for office and residential high-end decoration and making Longquan sword scabbard. The distribution range is narrowing day by day, and the wild resources are gradually exhausted. [0003] The conventional method of raising seedlings of red bean mainly adopts seed propagation, but because the flowering of red bean is late and unstable, it usually takes 35 years to bloom and bear fruit, and it will enter the peak fruiting period after 50 years, so the source of seeds and the number of seeds are difficult to meet the market demand. The conventional cuttin...

Problems solved by technology

[0004] The technical problem to be solved in the present invention is to overcome the defects of slow rooting, difficult rooting, low survival rate, long cultivation period and high cultivation cost of existing red bean tree cutting seedling cultivation technology, and its purpose is to provide a kind of method for fast rooting of red bean tree cuttings, with Shorten the rooting period, increase the survival rate of cuttings, reduce the cost of cultivation, and improve the market supply capacity of red bean seedlings
