Cutting seedling raising method for caribbean pines

Abstract

The invention discloses a cutting seedling raising method for caribbean pines. The method comprises the following steps: step 1, separately smashing dried pine needles, cottonseed hulls, peanut shells, bagasse, saw dust, artemisia argyi, paper scraps and corn stalks, mixing the smashed materials, performing soaking treatment, performing exposure treatment under the blazing sun, and performing expanding treatment to obtain a second mixture; step 2, mixing the second mixture with konjac flour, agar powder, clay brick powder, chitosan, hyaluronic acid, humus soil, sandy soil, fine river sand, perlite, citrus maxima inner peel powder, white gourd pulp, animal bone meal, waste coal residues and a fermentation material to obtain a third mixture; step 3, immersing the third mixture into the firstmixture, performing freezing, performing exposure under the blazing sun, and performing smashing to obtain a cutting matrix; step 4, performing girdling pretreatment on cutting ears, and performing atomization pretreatment; and step 5: sleeving the lower part of the pretreated cutting ears with cylinders, filling the cylinders with a nutrient fertilizer, and finally cutting the obtained cutting ears onto seedbeds. The method provided by the invention can improve the rooting rate and the survival rate of seedlings and shorten the rooting time.

Description

technical field [0001] The invention relates to the field of plant cutting propagation. More specifically, the present invention relates to a method for raising seedlings by cuttings of Pine caribbean. Background technique [0002] Caribbean pine alias Cuban pine, English name Caribbean Pine; Latin name Pinus caribaea Morelet; Pinaceae Pinus. Caribbean pine natives are distributed in the Bahamas in the Caribbean, western Cuba, Honduras on the eastern coast of Central America, eastern Guatemala and northeastern Nicaragua. Caribbean pine is a tree species with important economic value and ecological safety protection. It is not only an ideal raw material for pulp and paper, but also very suitable for poles, coastal piles, marine masts and construction materials. Due to its large resin content, the yield of turpentine is 2.4 times higher than that of masson pine, 32% higher than that of slash pine, and its quality is relatively good. It is a good resin-producing tree species....

AI Technical Summary

Problems solved by technology

[0003] At present, most of the Caribbean pine seedlings are cultivated from Caribbean pine seeds, but this seedling cultivation method takes a long time and costs a lot, and the obtained species of Caribbean pine seedlings are unstable

There are few research reports on the technology of caribbean pine cutting seedling raising, and the published cutting seedling raising technology has the problems of long seedling raising time and low rooting rate
