Embodiment 1

[0055] A kind of method for rapidly raising seedlings of semi-mangrove plant silver leaf tree, comprises the steps:

[0056] (1) Seed collection and disinfection: in the first ten days of October, collect ripe and insect-free silver leaf fruit, and silver leaf fruit is soaked in 0.03wt% potassium permanganate solution for 1h disinfection;

[0057] (2) Fruit pre-treatment: remove 1 / 3 of the husk from the fruit of the sterilized silver leaf tree (from the end of the fruit pedicle), expose the white endosperm, and remove the fruit with poor endosperm development, first in 100mg / L gibberellin solution soak in 150mg / L indole acetic acid solution for 0.5h, and finally soak in 20mg / L 6-benzyl adenine solution for 0.5h to accelerate germination;

[0058] (3) Soil preparation: level the seedbed, ensure smooth drainage, and remove weeds;

[0059] (4) Culture substrate configuration: the culture substrate is a mixture of sea mud and sea sand, and the volume ratio of the two is 1:1;

Embodiment 2

[0063] A kind of method for rapidly raising seedlings of semi-mangrove plant silver leaf tree, comprises the steps:

[0064] (1) Seed collection and disinfection: in the first ten days of October, collect ripe and insect-free silver leaf fruit, and silver leaf fruit is soaked in 0.5wt% potassium permanganate solution for 2h disinfection;

[0065] (2) Fruit pre-treatment: Excise 2 / 5 of the husk (from the end of the fruit pedicle) of the sterilized silver leaf fruit to expose the white endosperm and remove the fruit with poor endosperm development. Soak for 1.5 hours in the water, then soak in 180mg / L indole acetic acid solution for 1 hour, and finally soak in 50mg / L 6-benzyl adenine solution for 1 hour to accelerate germination;

[0066] (3) Soil preparation: level the seedbed, ensure smooth drainage, and remove weeds;

[0067] (4) Culture substrate configuration: the culture substrate is a mixture of sea mud and sea sand, and the volume ratio of the two is 1.5:1;

[0068] (5...

Embodiment 3

[0071] A kind of method for rapidly raising seedlings of semi-mangrove plant silver leaf tree, comprises the steps:

[0072] (1) Seed collection and disinfection: in the first ten days of October, collect ripe and insect-free silver leaf fruit, and silver leaf fruit is soaked in 0.25wt% potassium permanganate solution for 1.5h disinfection;

[0073] (2) Fruit pre-treatment: remove 1 / 3 of the husk (from the end of the fruit pedicle) of the sterilized silver leaf fruit to expose the white endosperm, remove the fruit with poor endosperm development, and first add 120mg / L gibberellin solution Soak for 1 hour, then soak in 160mg / L indole acetic acid solution for 0.75h, and finally soak in 35mg / L 6-benzyl adenine solution for 0.75h to accelerate germination;

[0074] (3) Soil preparation: level the seedbed, ensure smooth drainage, and remove weeds;

[0075] (4) Culture substrate configuration: the culture substrate is a mixture of sea mud and sea sand, and the volume ratio of the t...

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...
