specific Embodiment approach 1

[0022] Specific implementation mode one: this implementation mode is a method for improving saline-alkali land by a kind of croaker-grass comprehensive breeding, specifically completed according to the following steps:

[0023] 1. Layout: The saline-alkali land is divided into several plots to be treated by digging ditches and embankments, and a number of breeding ponds are set up in the saline-alkali land. The surroundings of each plot to be treated are dams, and the outside of the dam is ditch;

[0024] 2. Treatment: At the end of April, soak and wash several plots to be treated for 6 to 10 times, and then plant saline-alkali-tolerant pasture grass. The water consumption for a single soak and wash is 130m 3 / mu ~ 160m 3 / mu, to obtain the treatment of saline-alkali land wastewater;

[0025] 3. Each aquaculture pond is equipped with a bait feeder. The water source of the aquaculture pond is to control saline-alkali land wastewater, groundwater or river and lake water, and...

specific Embodiment approach 2

[0041] Specific embodiment 2: the difference between this embodiment and specific embodiment 1 is: the height of the embankment in step 1 is 40 cm, and the width is 80 cm. Others are the same as the first embodiment.

specific Embodiment approach 3

[0042] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: the ditch described in step 1 has a depth of 60 cm to 80 cm and a width of 80 cm. Others are the same as those in Embodiment 1 or 2.

Abstract

The invention discloses a leuciscus waleckii-pasture comprehensive planting and breeding saline-alkali soil improving method, and relates to a saline-alkali soil improving method, in particular to a method adopting leuciscus waleckii-pasture comprehensive planting and breeding for saline-alkali soil improving. The problems that according to existing saline-alkali soil improving methods, the improving efficiency is low, the project scale is large, the investment and operation cost is high, and the improvement effect is poor are solved. The leuciscus waleckii-pasture comprehensive planting and breeding saline-alkali soil improving method comprises the steps of 1 laying out the saline-alkali soil; 2, performing soaking and flushing; 3, preparing a culture pond; 4, performing fingerling stock;5, performing culture management, wherein feed feeding is performed, the oxygen content in water is controlled, the water quality is regulated, and bacillus powder is added into the culture pond periodically; 6, utilizing pond culture water in the culture pond for performing soaking and flushing in a plurality of land parcels to be treated. The method is used for saline-alkali soil improvement.

Description

technical field [0001] The invention relates to a method for improving saline-alkali land, in particular to the improvement of saline-alkali land by adopting crocodile-grass comprehensive breeding. Background technique [0002] Saline-alkali soil mainly refers to various saline soils, alkaline soils, and soils with different degrees of salinization or alkalization. It contains more saline-alkali components and has poor physical and chemical properties. Most plants cannot grow normally on its surface. There are about 36 million hm of saline-alkali land in my country 2 , and the salinized area has a tendency to expand year by year. At present, the improvement measures for saline-alkali land mainly include water conservancy improvement, physical and agricultural improvement, chemical and biological improvement, etc. In the application process of these technical measures, there are problems such as low improvement efficiency, large project scale, high investment and operation a...
