Abstract

The invention discloses a rapid seedling raising method for mangrove plant excoecaria agallocha. The method comprises the following steps of 1) selecting a coastal mud flat medium-tide zone as a nursery garden, removing weeds, and leveling the land; (2) cutting current-year semi-lignified branches of the middle-upper part of the excoecaria agallocha stock plant, wrapping the branches with a wet towel for moisturizing after picking, moving the branches to a shady and cool place for pruning the cutting slips, keeping the length of the cutting slips at 20-25cm, reserving 2-3 buds, removing leaves, wax-sealing top cuts of the branches, and cutting bottom cutting openings into inclined planes to be smooth; enabling the cutting slips to be soaked in rooting liquid for 2-3 h and then inserted into a matrix of a seedling culture nutrition bag, after seedlings grow for a period of time, enabling the seedlings to be transplanted into the matrix of the non-woven fabric seedling culture bag to becultured and taken out of a nursery, and obtaining excoecaria agallocha seedlings. According to the method, the seedling survival rate reaches up to 90%-95%, operation is easy, the cost is low, the seedling period is short, a large number of high-quality excoecaria agallocha seedlings can be obtained in a short time, and a reliable technical guarantee is provided for ecological restoration of thetropical coastal mangrove forest.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a method for rapidly growing seedlings of mangrove plant lacquer. Background technique [0002] Sea lacquer, also known as soil agarwood, belongs to Euphorbiaceae and genus Agarwood, and is a dicotyledonous plant, shrub or tree-like. It is mainly distributed in Hainan, Guangdong, Guangxi, Fujian (extinct), Hong Kong and Taiwan, India, Sri Lanka, It is also distributed in Thailand, Cambodia, Vietnam, the Philippines, and Australia. Sea paint grows on the saline-alkali land in the high tide zone or super high tide zone in the sea-land transition zone. It does not have high requirements on the soil. It can grow on the wet and poor gravel soil or the high place on the edge of the tidal trench. It is a typical amphibious species. Half mangrove plant. It grows faster and is one of the pioneer species of mangrove afforestation. [0003] At present, there are rel...
