Technique for forestation of Chinese tamarisk on coastal tidal flats

Abstract

The invention relates to a technique for the forestation of Chinese tamarisk on coastal tidal flats. According to the technical scheme of the invention, the technique comprises the following technological steps: (1) cultivating the shoot of Chinese tamarisk on plots with the salt content thereof being 0.3% to 0.6% by using the cutting propagation method; (2) transplanting the shoot of Chinese tamarisk to flowerpots or other containers to cultivate the container seedling of Chinese tamarisk, wherein the salt content of soil in the container is approximately 1.0% and no higher than 1.2%; (3) transplanting the ball-plant container seedling of Chinese tamarisk with the complete root system to the coastal tidal flats by proper density, wherein according to the conditions for selecting the coastal tidal flats, the coastal tidal flats can be immersed in seawater for a short time instead of immersed continuously for a plurality of days, and the salt content of the tidal flat soil is no higher than 3.0%. The invention has the following beneficial effects: by using the container seedling method, the invention guarantees the complete root system of Chinese tamarisk during the transplanting process, thereby avoiding the effect of root cutting and further increasing the survival rate of forestation of Chinese tamarisk under the condition that the salt content is high. Therefore, the technique is particularly suitable for the actual conditions in the area of coastal tidal flats short of freshwater resources.

Description

1. Technical field: [0001] The invention relates to a Chinese tamarisk afforestation technology, in particular to a Chinese tamarisk afforestation technology on coastal tidal flats. 2. Background technology: [0002] There are more than 20 kinds of Tamarix Chengliu in my country, mainly distributed in coastal saline-alkali areas, followed by a small amount of Chinese Tamarix and multi-branched Tamarix. Tamarix is ​​resistant to salt, drought, and seawater immersion. It is distributed in the intertidal zone of coastal beaches, so it is also known as the northern mangrove. Most of the Tamarix growing on the beach is because the seeds of Tamarix are washed on the beach during the rainy season. The place where there is rainwater gathers to take root, germinate, and grow gradually. Because the germination of Tamarix seeds requires low salt content conditions, the distribution of Tamarix in coastal beaches under natural conditions mainly depends on the amount of Tamarix seeds?

Problems solved by technology

[0003] The current problem is: Chinese tamarix can withstand short-term seawater immersion, but it does not mean that Chinese tamarisk can be directly afforested on coastal beaches. % of the plots achieved a high survival rate of afforestation, but the survival rate was very low on the plots with a salt content higher than 1.5%
