Problems solved by technology

[0012] The existing seedling raising method of viviparous mangrove species generally adopts nutrient bags to raise seedlings directly. This method is not high enough in survival rate when mangrove afforestation, and the afforestation cost is high, so it is difficult to be used for ecological restoration of mangroves on difficult sites.

Embodiment 1

[0046] A kind of bamboo raft seedling raising method of viviparous mangrove tree species, concrete steps are as follows:

[0047] When harvesting mangrove viviparous seedlings, choose mature, plump and disease-free mangrove viviparous seedlings, either fresh or on the ground. When harvesting, be careful not to let the seeds suffer later damage, such as exposure to the sun, dehydration, etc.

[0048] Wash the harvested mangrove viviparous seedlings with water, remove diseased seeds, and select seeds with a maximum diameter of more than 1 cm. Soak with low-concentration rooting powder for 1 to 5 hours, then transplant to seedling raising bamboo rafts and put them into a pre-prepared pool with a water temperature of 20 to 25 °C.

[0049] Nutrient pools: hardened with conventional cement or natural pools. The depth of the pool water is not less than 15 cm, and the pool water is adjusted to the conventional seawater ratio or directly watered with seawater. During the seedling raisi...

Embodiment 2

[0057] This embodiment is the second embodiment of the method for raising seedlings on bamboo rafts of viviparous mangrove species. The difference between this embodiment and Embodiment 1 is that in the cultivation process, it also includes the use of seawater with a salt content of 2.0% to 2.5% for mangroves. The step that tree viviparous seedlings are sprayed;

[0058] Other steps are identical with embodiment 1.

[0059] To cultivate seedlings for afforestation, it is advisable to use seawater spray irrigation with a salt content of 2.0% to 2.5%, or mix high-salinity seawater with an appropriate amount of fresh water for spray irrigation to improve the vitality of seedlings. Sprinkling frequency can be carried out irregularly at least once a month.

Abstract

The invention discloses a bamboo raft seedling growing method for viviparous mangrove species. The method comprises the following steps: S1, soaking harvested viviparous mangrove seed seedlings by using rooting powder; S2, inserting the treated viviparous mangrove seed seedlings into a seedling growing bamboo raft, placing the seedling growing bamboo raft in a nutritional water pool, and performing culturing, wherein the seedling growing bamboo raft is composed by arranging a plurality of bamboos, and the seedling growing bamboo raft is provided with a plurality of seedling growing positions;and S3, lifting the seedlings after the culture of the viviparous mangrove seed seedlings is completed. The bamboo raft seedling growing method adopts the seedling growing bamboo raft and the nutritional water pool to carry out seedling insertion and cultivation, makes the viviparous mangrove seed seedlings grow and develop well and be easily lifted and transplanted, can significantly improve thesurvival rate during mangrove forestation and reduce the forestation cost, and is suitable for the ecologic restoration of mangroves in a difficult site. Mangrove resources are cherished resources ofscientific research, and have the values of protection and appreciation. The seedling growing method can greatly promote the forestation work of mangroves, and has a broad market prospect.

Description

technical field [0001] The invention relates to the technical field of seedling raising, and more specifically, relates to a bamboo raft seedling raising method for viviparous mangrove species. Background technique [0002] Mangroves are woody plant communities that grow on the beaches of tropical and subtropical coastal areas. my country's Zhejiang, Fujian, Guangdong, Guangxi, Hainan Island and the coastal areas of Taiwan all have its distribution. Most of the mangrove forests are very dense. When the tide is high, the trunks of the trees are partially or completely submerged by the sea, and the crowns of the trees are often rippling on the water surface; [0003] Mangroves are mostly composed of evergreen trees and shrubs, which can be composed of a single tree species or as many as dozens of tree species. The plant species that make up mangroves can be divided into true mangrove plants (tree species) and semi-mangrove plants (tree species) according to their growth type...
