Problems solved by technology

[0004] However, generally mangrove plants are suitable for growth in a light saline environment with a salinity of 5ppt to 15ppt. Completely fresh water will cause poor growth of mangroves and are prone to pests and diseases
At present, although relevant researchers have begun freshwater cultivation of mangrove plants, they have not achieved ideal results.

Embodiment 1

[0016] 1) Seedbed selection and preparation

[0017] Prepare a seedbed with a moderate area, and use tidal flat soil suitable for mangrove plant growth as its growth substrate.

[0018] 2) Mangrove embryo selection and pretreatment

[0019] Choose tung flower tree (Aegiceras corniculatum) as the mangrove plant for freshwater domestication and cultivation, use a clean container, such as a tank, bucket, etc., use coarse sea salt and aeration to prepare light salt water according to the concentration ratio of 2‰, and filter The well-developed mangrove embryos are soaked in light salt water for one day and one night.

[0020] 3) Freshwater domestication technology

[0021] The soaked tung flower tree (Aegiceras corniculatum) embryos were planted in the seedbed prepared in advance, and the distance between each plant and row was 50 cm. From the date of planting, the saline water with a salinity of 20‰ prepared with coarse sea salt and aerated tap water was used for irrigation an...

[0025] 1) Seedbed selection and preparation

[0026] Prepare a seedbed with a moderate area, and use tidal flat soil suitable for mangrove plant growth as its growth substrate.

[0027] 2) Mangrove embryo selection and pretreatment

[0028] Choose tung flower tree (Aegiceras corniculatum) as the mangrove plant for freshwater domestication and cultivation, use a clean container, such as a tank, bucket, etc., use coarse sea salt and aeration to prepare light salt water according to the concentration ratio of 2‰, and filter The well-developed mangrove embryos were soaked in light salt water for 30 hours.

[0029] 3) Freshwater domestication technology

[0030] The soaked embryos were planted in the pre-prepared seedbed, and the distance between plants and rows was 60 cm. From the date of planting, the salt water with a salinity of 23‰ prepared by coarse sea salt and aerated tap water was used for irrigation and cultivation for 15 hours every day. After 20 days, the concentrati...

Abstract

The invention provides a fresh water acclimatization culture method of a mangrove plant, comprising acclimatization culture steps as follows: selection of well-developed Aegiceras corniculatum embryo, saline soaking processing with salinity of 2 per thousand, planting of the processed Aegiceras corniculatum embryo in a seedling culture bed and fresh water acclimatization culture for the planted Aegiceras corniculatum according to the set cycle and salinity gradient. By utilizing the method for fresh water acclimatization culture of the Aegiceras corniculatum of the mangrove plant, the survival rate can reach up to over 90%, the Aegiceras corniculatum of the mangrove plant after acclimatization can grow under the environment of light salt brine and completely fresh water and is suitable to be planted under wetland environment of lake, reservoir and estuary lake and reservoir and estuary, and the Aegiceras corniculatum of the mangrove plant plays an important role in soil and water ecological conservation of fresh water wetland systems.

Description

Technical field: [0001] The invention relates to the technical field of plant cultivation, in particular to a cultivation method for improving the planting characteristics of the mangrove plant Aegiceras corniculatum. Background technique: [0002] Freshwater basins such as lakes, reservoirs, and estuaries are typical types of wetland systems. Although these wetland systems do not have periodic tidal fluctuations, their water surface heights also fluctuate up and down. When the water level drops, the soil layers along the shores of lakes, reservoirs, and estuaries will be exposed to the air. When exposed to the sun, it will easily lead to the loss of nutrients and water in the soil layer. Rainwater invasion may also cause the surface layer to peel off, which is not conducive to these Soil and water conservation in freshwater wetland systems. [0003] Soil and water conservation in wetland systems such as lakes, reservoirs, and estuaries can be achieved by planting vegetatio...
