Rapid seedling raising method for hemi-mangrove plant heritiera littoralis dryand

Abstract

The invention relates to the technical field of forestry afforestation, in particular to a rapid seedling raising method for semi-mangrove plant heritiera littoralis dryand. The rapid seedling raising method comprises the following steps that (1), seed collection and disinfection are carried out, specifically, mature and pest-free heritiera littoralis dryand fruits are collected and disinfected; (2), the fruits are pretreated, specifically, part of shells of the disinfected heritiera littoralis dryand fruits are cut off, the fruits with poor endosperm development are removed, and the fruits are soaked in a solution A to accelerate germination; (3), soil preparation is carried out, specifically, a seedbed is leveled, smooth drainage is ensured, and weeds are removed; (4), a medium is prepared, specifically, the culture medium is prepared from sea mud, sea sand and plant ash; (5), planting is carried out, specifically, the fruits subjected to germination acceleration are planted in a nutrition bag filled with the culture medium; and (6), seedlings are transplanted, specifically, when the height of the seedlings of the heritiera littoralis dryand is 20-30cm, the seedlings are transplanted into non-woven bags filled with the culture medium in the step (4), the height of the seedlings is 45-55cm, and the seedlings can be outplanted. The rapid seedling raising method for the semi-mangrove plant heritiera littoralis dryand has the advantages of being good in germination rate, seedling preservation rate and seedling height effect and short in seedling raising period.

Description

technical field

[0001] The invention relates to the technical field of forestry afforestation, in particular to a method for rapidly growing seedlings of the semi-mangrove plant silverleaf. Background technique

[0002] Semi-mangrove plants refer to amphibious woody plants that can survive in the intertidal zone, become dominant species on the beach, and reproduce naturally in the terrestrial environment.

[0003] Silver-leaved tree (scientific name: Heritiera littoralis Dryand.) is a plant of the genus Silver-leaved Tree of the Sycamore family. It is distributed in the intertidal zone of tropical and subtropical coasts or on the coast of estuaries. Rare amphibious mangrove plant. Silver leaf tree branchlets and the back of leaves are covered with silvery white scales, which can be used to reflect strong light, reduce temperature, and reduce water loss, hence the name of silver leaf tree. At the base of the trunk of the silver leaf tree, there are plank roots with a relati...
