specific Embodiment approach 1

[0023] Specific embodiment one: present embodiment is a kind of saline-alkali land fishery-agricultural comprehensive breeding method, specifically completes according to the following steps:

[0024] 1. Layout: The saline-alkali land is divided into several plots to be treated by digging ditches and dams, and aquaculture ponds are set in the saline-alkali land. The surroundings of each plot to be treated are dams, and the outside of the dams are ditches;

[0025] 2. Treatment: At the end of April, soak and rinse several plots to be treated for 6 to 10 times, and then plant saline-alkali-tolerant plants. The water consumption for a single soak and rinse is 130m 3 / mu ~ 160m 3 / mu, to get the treated saline-alkali land wastewater;

[0026] 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 the water storage capacity of 1 acre of aquaculture pon...

specific Embodiment approach 2

[0042] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the height of the embankment described in step one is 40cm, and width is 80cm. Others are the same as the first embodiment.

specific Embodiment approach 3

[0043] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: the depth of the ditch described in step one is 60cm~80cm, and the width is 80cm. Others are the same as those in Embodiment 1 or 2.

Abstract

The invention discloses an agricultural-piscatorial comprehensive planting-breeding method used for saline and alkaline land and relates to a saline and alkaline land improving method, in particular to adopted agricultural-piscatorial comprehensive planting-breeding saline and alkaline land and aims to solve the problem that an existing saline and alkaline land improving method is low in improvingefficiency, large in construction scale, high in investment, operation and maintenance cost and poor in improvement effect. The agricultural-piscatorial comprehensive planting-breeding method used for saline and alkaline land comprises the steps of saline and alkaline land layout, soaking and flushing, breeding pond preparation, fingerling stocking, breeding management including feeding putting,water oxygen content control, water quality regulation and control, periodical adding of bacillus powder towards breeding ponds, and soaking and flushing of a plurality of plot to be treated by utilizing pond breeding water in the breeding ponds. The agricultural-piscatorial comprehensive planting-breeding method is used for improving the saline and alkaline land.

Description

technical field [0001] The invention relates to a method for improving saline-alkali land, in particular to improving saline-alkali land by adopting fishery-agricultural 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, which contain more saline-alkali components and poor physical and chemical properties, and most plants cannot grow normally on the 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 and ...
