Problems solved by technology

[0005] However, at present, the seedling breeding and cultivation technology of semi-mangrove mangrove is still in a blank state. Through the research and development of mangrove seedling breeding and cultivation technology, it can be applied to the protection, research and development of mangrove, afforestation and expansion, and increase the diversity of mangroves. , can be applied to bioremediation and landscape configuration of coastal wetlands, and has broad market prospects

Embodiment 1

[0029] In June 2009, along the coastline of the Dongchong River in Dapeng, Shenzhen, a piece of land was selected to be flattened and used as a nursery (3m×10m) in a place where the wind and waves are small and the seawater can hardly be submerged, and it was disinfected according to step A. In July 2009, 1,200 fruits were collected in the mangrove distribution area of ​​Dongyong River, Shenzhen, and 2,500 seeds were selected after soaking and disinfection (1 sea lacquer fruit contains 2-3 seeds). Sow directly, 15 cm apart and 30 cm apart in rows. After sowing, the seedbed is sprayed or watered with fresh water or sea water according to step D. After 10 days, seedlings emerge from the ground one after another, and the emergence rate reaches 98% after 25 days. In October, 2085 surviving seedlings reached an average height of 25 cm. In February 2010, 1980 saplings with an average height of 0.55 m were obtained. In March 2010, 1,980 surviving sea varnish seedlings were transpla...

Embodiment 2

[0031] In May 2013, a flat piece of land was selected in the seaside countryside in the west of Shenzhen, where the wind and waves are small and the seawater can hardly be submerged. It was used as a nursery, and it was disinfected according to step A. In May 2013, 800 fruits were collected in the mangrove distribution area by the seaside of Kaozhouyang, Huidong County, and 1,000 seeds were selected after soaking and disinfection (1 sea lacquer fruit contains 2-3 seeds). Sow directly, 15 cm apart and 30 cm apart in rows. After sowing, spray or irrigate the seedbed with fresh water or salt water according to step D. After 15 days, seedlings emerge from the ground one after another, and the emergence rate reaches 95% after 40 days. In October, 923 surviving seedlings reached an average height of 38 cm. In February 2014, 878 sea varnish saplings with an average height of 0.82m were obtained. In March 2014, 878 surviving sea lacquer seedlings were transplanted to the seaside of ...

Embodiment 3

[0033]In June 2011, in the mangrove distribution area of ​​the Dapeng Xichong River Estuary, a piece of land with little wind and waves and hardly inundated by seawater was selected to be used as a nursery, and disinfected according to step A. In July 2011, 1,500 fruits were collected on both sides of the Dapeng Xichong River, and 2,000 seeds were selected after soaking and disinfection (1 Haiqi fruit contains 2-3 seeds). Sow directly, 20 cm apart and 25 cm apart in rows. After sowing, the seedbed is sprayed or watered with fresh water or sea water according to step D. After 15 days, seedlings emerge from the soil one after another, and the emergence rate reaches 89.1% after 40 days. In October, 1650 surviving seedlings reached an average height of 35-40 cm. In February 2012, 1,646 sea lacquer saplings with an average height of 0.75-0.90 m were obtained. In March 2012, 1,646 surviving sea lacquer seedlings were transplanted to the seaside near Yangshuo Island, Kaozhou, Huido...

Abstract

The invention provides a seedling breeding and cultivation method for excoecaria agallocha of mangrove plants. The method comprising the following steps that A, the land nearby a mud flat high-tide zone is selected as a nursery garden, the land is leveled, a drainage field ditch is formed, and disinfection is carried out; B, plants with the plant height not smaller than 3 m and without plant diseases and insect pests are selected as seed trees, and excoecaria agallocha fruits with the full form and yellow peels are harvested in June to August on the Gregorian calendar; C, harvested and disinfected excoecaria agallocha seeds are directly seeded in a substrate of the nursery garden, and sunshade treatment is carried out; D, alternate domestication is carried out through sea water and fresh water; E, after the excoecaria agallocha seedlings grow to 0.5 m to 1.5 m, transplantation and seedling toughening are carried out. The method has the advantages that cost is low, the seed germination rate is high, the transplantation range of the excoecaria agallocha is expanded, the seedling survival rate of the excoecaria agallocha seedlings is improved, and the wide development prospect is achieved.

Description

technical field [0001] The invention relates to a method for afforestation and multiplication of mangroves, in particular to a method for breeding and cultivating mangrove plant sea lacquer seedlings. Background technique [0002] Sea paint ( Excoecaria agallocha ), belonging to Euphorbiaceae (Euphorbiaceae), sea paint ( Excoecaria ), shrub or tree-like, dicotyledonous, dioecious, raceme, flowering and fruiting period from January to September, and the fruit of sea lacquer is plastic fruit. Sea lacquer is mostly scattered on the inner edge of the mangrove ecological sequence above the high tide zone, and can only be flooded by spring tide or super tide, or in areas where there is no tide all year round. It is one of the important semi-mangrove plants in my country and is a non-viviparous species. . Sea lacquer is distributed in Hainan, Guangdong, Guangxi, Hong Kong, Taiwan and other places in China. The original distribution in Fujian Province is now extinct. [0003] Th...
