Method for raising seedlings of plant kandelia candel fruit in mangrove forest

Abstract

The invention provides a method for raising seedlings of plant kandelia candel fruit in a mangrove forest, which is used for planting the kandelia candel in a region from the north of 25 degrees northlatitude to 40 degrees north latitude. The method comprises the following steps: 1, collecting kandelia candel fruit, 2, after October, arranging a constant temperature shed on an empty land of a coastal beach; 3, soaking kandelia candel seeds in potassium permanganate solution for 30 minutes, and then taking out the seeds and airing for later use; 4, screening the kandelia candel fruit which isdamaged or rotted, and inserting the intact kandelia candel fruit into the sea silt in the constant temperature shed with the roots downwards to carry out seedling raising so that the kandelia candelfruit grows into a kandelia candel seedling; 5, transplanting the kimchi seedlings, and enabling the kandelia candel seedlings to adapt to the temperature transition from 15 DEG C of the constant-temperature shed to 10 DEG C of outdoors to 0 DEG C of the seawater so as to adapt to the local climate temperature. The method is simple, easy to carry out and low in cost, and the risks of high cost, high death rate and the like which frequently occur in manual seedling digging, transportation, planting and the like in the transplanting process are avoided; and meanwhile, the survival rate of the kandelia candel seedlings in high-latitude areas is ensured.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a method for raising seedlings of candela fruit in mangroves. Background technique [0002] Nantong is located between 31°1'-32°43' north latitude and 120°12'-121°55' east longitude. It has a north subtropical and warm temperate monsoon climate, with abundant sunlight and rain, four distinct seasons, and a mild and pleasant environment. Nantong has a total area of ​​more than 6 million mu of coastline from the coastal area of ​​Dongtan in Shanghai to the coastal tidal flats of Lianyungang in Jiangsu. Jiangsu Province stipulates that more than 2 million mu will be designated as an ecological bird and aquatic nature reserve. In order to protect the reproduction of birds and various organisms in the ocean, and to protect the ecological balance of coastal beaches, the only option is to plant various species of mangroves in seawater. We have screened and compared the plants ...

AI Technical Summary

Problems solved by technology

[0007] In view of the foregoing, the present invention provides a method for raising seedlings of candela fruit in mangroves, which solves the problem that the annual seedlings of candela can not survive the winter in an environment of -10 degrees, which causes candela seedlings to be transplanted to the north of 25 degrees north latitude. The coastal tidal flat areas between 40 degrees north latitude and 40 degrees north latitude cannot survive, and a large amount of manpower and material resources are consumed in the transportation process, resulting in technical problems of high cost and high mortality
