Sulfate type saline-alkali pond construction system and ecological breeding and planting method

Abstract

The present invention provides a sulfate type saline-alkali pond construction system and an ecological breeding and planting method. The construction system comprises a ring-like outer channel, one end of the ring-like outer channel is provided with a water inlet communicated with an external water source, and the other end of the ring-like outer channel is provided with a water outlet communicated with an external drainage channel; the area enclosed by the ring-like outer channel is divided into m*n planting regions, each planting region comprises a rice field and a field ridge, a circular trench and a channel ridge which successively surround the rice field from inside to outside, an inner channel communicated with the ring-like outer channel is disposed between any two adjacent plantingregions, and each field ridge and each channel ridge are respectively provided with a water gate; m and n are integers greater than or equal to 2. Ecological breeding and planting operation can be well performed in saline-alkali areas, direct influence of water between the channel and the rice field can be relieved, the rice field can also be prevented from being influenced by the excessively high water level in the production period, and fish can also be prevented from entering the rice field.

Description

technical field [0001] The invention relates to the field of ecological breeding, in particular to a construction system for a sulfate-type saline-alkali pond and an ecological breeding and planting method. Background technique [0002] Saline-alkali water is the third water resource different from seawater and fresh water. There are 690 million mu of saline-alkali water resources in my country, which are widely distributed in 19 provinces, municipalities and autonomous regions in China, and are increasing year by year. my country is a country short of fresh water resources. Several droughts in recent years have had a great impact on agricultural production. Therefore, the Ministry of Water Resources has clarified that the red line of total water consumption in 2020 will not exceed 670 billion cubic meters, and put forward more strict regulations on the development and utilization of unconventional water sources. high demand. [0003] my country is a large agricultural coun...

Problems solved by technology

[0005] At present, it is difficult to carry out planting and breeding operations in some saline-alkaline areas (such as the arid Northwest region)

At the same time, at present, the canals are generally directly irrigated to the rice fields through the gaps. During the i...
