Embodiment Construction

[0038] Applying and implementing the technical scheme of the present invention in the cotton field of Haixing State-run Haixing Farm, Cangzhou City, Hebei Province, comprises the following steps:

[0039] Formed through several years of construction and improvement: the water surface area of ​​the ecological control pool 1 is 1.0hm 2 , the water depth is 3.5m, and the water surface area of ​​the breeding pond 2 is 0.2hm 2 , the water depth is 1.8m; the ecological control pond 1 and the breeding pond 2 jointly form a circular pond, and a control gate 10 is provided at the connecting position of the two to control the connection or closure of the two ponds. Terrace 3 has a height of 1.8m and a width of 200m; the bottom of Terrace 3 is paved with isolation materials: no laying is carried out at 0-50m from the pond, corn straw is laid at 51-100m, cotton straw is laid at 101-150m, and reed straw is laid at 151-200m. The method is compaction, the thickness is about 20cm; the platfo...

Abstract

The invention provides a coastal saline-alkali soil ecological improvement system. The system comprises an ecological regulation pond, a culture pond, a platform field, an alkali discharge ditch and a shallow groundwater extraction system, the ecological regulation pond and the alkali discharge ditch are connected with the alkali discharge ditch and a river through ditches, the ecological regulation pond performs rainy season fresh water accumulation and individual rainy year water draining, and the culture pond performs underground water or fresh water supplementing and aquaculture. The platform field is paved with different kinds of straw according to different distances with the pond, the shallow groundwater extraction system provides power by means of blending of wind energy and solar energy to extract shallow groundwater continuously day and night. The invention further provides a matched high-yield cotton planting method. Accordingly, adversity stress of saline-alkali, drought and water logging of coastal saline-alkali soil is significantly changed, and normal growth and development of cotton are promoted; meanwhile, the pest and disease damage is significantly lowered, management is conducted more conveniently, the cotton yield is significantly increased, the cotton quality is significantly improved, and the cotton planting earnings of farmers are directly increased.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a coastal saline-alkali land ecological improvement system and a high-yield cotton planting method thereof. Background technique [0002] Cotton is the second largest crop after grain in my country, and it is a strategic material related to the national economy and people's livelihood. With the social progress and development, the demand for food increases, and the contradiction between grain and cotton competing for land becomes increasingly prominent. It has become one of the main trends of my country's cotton production to transfer cotton with strong saline-alkaline tolerance to coastal saline-alkali areas with low production capacity. one. The climate in coastal saline-alkaline areas is characterized by uneven distribution of precipitation within a year and large differences between seasons. The saline-alkali area around the Bohai Sea is dry in spring an...
