Embodiment 1

[0022] In the plant selection base of saline-alkali land in Nansha District, Guangzhou, the ripe cattail fruit was harvested in time, the fruit was dried in the sun and split naturally, and the seeds were collected, mixed with fine river sand at a mass ratio of 1:3, and spread over the whole area. Cover the fine and flat seedbed with about 1cm of thin sand, and then cover it with straw, so that the soil is not visible, and keep it moist by pouring water every day. Covering the straw can prevent exposure to the sun and water evaporation. After about 2 weeks, the seeds will start to germinate, and the cover will be covered Remove the straw, support it with a bamboo bow, cover it with a shading net with a shading rate of 90%, and keep it moist every day. % shading rate of the shading net for shading, and the shading net can be removed after about 1 month. When the seedling height is 30cm, move it to a planting bag with a specification of 20cm×20cm×20cm. The planting bag is equippe...

Abstract

The invention provides a method for ecologically greening coastal saline and alkaline land, which is characterized by comprising the following steps: seeds of syzygium odoratum (Lour.) DC. which has the characteristics of saline and alkaline resistance, water and humidity resistance, fast growth rate, luxuriant foliage, beautiful shape and attractive flowers and fruit are sowed for propagation, after seedlings are 30cm high, the seedlings are transplanted into planting bags with a certain salt matrix and conventionally managed in a seedling nursery, and the syzygium odoratum (Lour.) DC. of two years old is moved out of the seedling nursery to be directly applied to greening the saline and alkaline land and managed by adopting the conventional garden technology, wherein the syzygium odoratum (Lour.) DC. of three years old has the height of over 2m and the crown size of 1m*1m, is green all year round, has red fresh leaves and creates the beautiful landscape. The syzygium odoratum (Lour.) DC. has very good application prospects in coastal saline and alkaline land and coastal beaches in the southern part of China.

Description

Technical field: [0001] The invention belongs to the field of ecological and environmental protection science and technology, and in particular relates to a method for ecological greening of seaside saline-alkali land. Background technique: [0002] Soil salinization has become one of the most important environmental problems in the world. According to incomplete statistics from the United Nations Educational, Scientific and Cultural Organization (UNESCO) and the Food and Agriculture Organization (FAO), the current global saline-alkali land area is about 950 million hectares 2 , accounting for 25% of the land area, the saline-alkali land area in my country is about 99.13 million hm 2 , accounting for about 1 / 28 of the saline-alkali land in the world, and the area is equivalent to 1 / 4 of the existing cultivated land in my country. The saline-alkali soil in my country is mainly distributed in five major regions, namely the coastal saline-alkali soil area, the North China sal...
