Embodiment 1

[0020] 1) Seed collection and treatment: select large-grained, insect-free seeds, soak the seeds in water for 0.5 hours, put the seeds in the sun, wash them with water after taking them out, and soak them in water every 7 hours for 4 hours. First time, when soaking in water, turn the seeds gently, and pick out the seed coat, and finally place the seeds in a cool place, soak them in insecticide for 8 minutes, and drain them naturally;

[0021] 2) Sowing: Insert the seeds into the pre-prepared nutrient bag, insert the long radicle end of the seed downward into the nutrient soil in the bag, the insertion depth is 1 / 3 of the seed, and sow 1 seed in each nutrient bag , after sowing, irrigate with fresh water or low-salinity seawater;

[0022] 3) Seedling management:

[0023] ①Hydraulic management: within 4 days of sowing, water the seedlings with fresh water once a day in the morning and evening; Wash away the silt to prevent the silt from adhering to the seedlings;

[0024] ②Fe...

Embodiment 2

First time, when soaking in water, turn the seeds gently, and pick out the seed coat, and finally place the seeds in a cool place, soak them in insecticide for 9 minutes, and drain them naturally;

[0029] 2) Sowing: Insert the seeds into the pre-prepared nutrient bag, insert the long radicle end of the seed downward into the nutrient soil in the bag, the insertion depth is 1 / 3 of the seed, and sow 2 seeds in each nutrient bag , after sowing, irrigate with fresh water or low-salinity sea water;

[0030] 3) Seedling management:

[0031] ①Hydraulic management: within 5 days of sowing, water the seedlings with fresh water once a day in the morning and evening; Wash away the silt to prevent the silt from adhering to the seedlings;

Abstract

The invention discloses a mangrove plant Avicennia marina seedling raising method, which comprises the steps of seed collection and treatment, seeding, seedling management and seedling hardening and outplanting, wherein the seedling management comprises water management and fertility management. Avicennia marina seeds are put under sunshine after the Avicennia marina seeds are soaked in water to promote the germination of the seeds; when the seeds are interruptedly soaked in water, the seeds are slightly stirred to promote the aerobic respiration of the seeds and further accelerate the germination of the seeds; and since the situation that the seeds are rotted at the period when seedling height is 5-15cm, chlorothalonil is sprayed at an interval of 5 days to prevent the seeds from being rotted, the seeds can be prevented from being rotted and the survival rate is improved.

Description

technical field [0001] The invention relates to a method for raising seedlings of plants, in particular to a method for raising seedlings of the mangrove plant cochineal. Background technique [0002] Mangroves are woody plant communities that grow in the intertidal zone of tropical and subtropical coasts. They have huge ecological, economic, and social values. important role. Bone soil (also known as sea olive, sea bean, and salt water dwarf wood) is a plant of the family Verbenaceae in mangroves. It is the largest mangrove plant species in my country, and it is also the mangrove with the strongest salt and flood tolerance. Tree plants, which have wide adaptability to soil and are not demanding on soil fertility, can appear on silt, semi-silt and sandy beaches. With the development of the economy, problems such as deforestation and aquaculture and seawater pollution have become more and more serious, and its ecological system has suffered serious damage. The development mo...
