Embodiment

[0026] The cultivation method of sea mulberry seedlings is carried out through the following steps:

[0027] (1) Nursery stock cultivation

[0028] ① Sowing seedlings

[0029] Disinfect seeds and seedbeds with 3-5g / L potassium permanganate solution before sowing. Take the reserved sea mulberry seeds, rinse them with clean water and sow them on the seedbed. The sowing method is evenly spread, and covered with 1.0cm thick nutrient soil, then lightly compacted with a wooden board, and then covered with a film.

[0030] ② Seedling management

[0031] When the true leaves of S. apetalum seedlings come out, introduce seawater to irrigate the seedling border; when the seedlings have 2-3 true leaves, pour the seedlings with fresh water to keep the border moist, and introduce seawater soaked seedling border at the same time; when the seedlings grow out When there are 3-4 true leaves, the stem is more than 2cm and the degree of lignification is strong, introduce seawater immersion s...

Abstract

The invention discloses an efficient cultivation method for sonneratia apetala Buch-Ham seedlings. The purpose is to solve the problems that in the forestation initial stage of sonneratia apetala Buch-Ham, the survival rate is low, and the preserving rate is low. The method includes the following steps of seedling cultivation, seedling transplanting and stem and root cutting, and the cultivation method has the advantages that stem cutting and secondary root cutting are performed on the container-grown seedlings of certain specifications in the later stage of sonneratia apetala Buch-Ham seedling cultivation, so that the sonneratia apetala Buch-Ham seedlings are developed in root system, plants are robust, the thickness of stems is increased obviously, and high-quality seedlings good in uniformity can be provided for coast protection forest construction. The seedlings cultivated by the application of the technology can make the original forestation survival rate be improved above 95% from 85%, and the original preserving rate of annual growth sonneratia apetala Buch-Ham can be improved to 90% from 81%. Therefore, compared with the traditional mode that half year growth seedlings of the 40cm-70cm height are adopted for performing forestation, the forestation survival rate and the preserving rate are greatly improved. The technology is particularly suitable for performing mangrove forest forestation on coastal mud flat.

Description

technical field [0001] The invention relates to a seedling cultivation technique in forestry, in particular to a seedling cultivation method of Sangria apetalum among mangrove plants. Background technique [0002] Sonneratia apctala Buch-Ham is a plant of the family Sonnerataceae, native to the mangrove area of ​​Sundarban, Bangladesh. It is a tall tree with rapid growth, developed root system, and bamboo-like respiratory roots. It is a bare beach Pioneer tree species for plantation. In recent years, the mangrove forests in coastal tidal flats in our area have been damaged in different ways and in varying degrees, resulting in the deterioration of the coastal ecological environment. Therefore, it is imperative to vigorously promote coastal mangrove afforestation. The introduction of Sangria apetalum is conducive to changing the stand structure of coastal tidal flats, changing the single-layer forest structure into a multi-layered forest structure, and creating conditions fo...
