Description

Rainwater collecting device in saline-alkali soil drainage ditch

Technical Field

The utility model belongs to the technical field of the collection rain device, concretely relates to collect rain device in saline and alkaline land escape canal.

Background

The salt in the soil migrates with the movement of water, and when water in the soil is lost by evaporation, the salt in the soil is left in the soil and is concentrated to the surface. If the ground water level is too high for a long time, soil moisture evaporation can be aggravated and then the enrichment of soil salinity on the top layer is aggravated, and because higher ground water level rainfall can not drip wash soil top layer salinity to deep soil again, the soil salinization of a long time aggravates, and then forms saline-alkali soil, influences the production of crop planting and grain. In order to reduce the underground water level and control the salinity of soil, an open ditch or an underground concealed pipe is generally adopted for draining water and discharging salt. The open ditches are deep ditches dug at two sides of the field and connected with the main drainage ditch, and when the underground water level with excessive moisture in the field soil is higher than the bottom of the ditches in rainy season, the moisture in the field soil can be drained into the open ditches at the two sides and flows to the drainage ditches to be further drained into rivers, lakes and seas. But the open trench drainage occupies cultivated land, so that the cultivated land is reduced. The hidden pipe drainage is that the drain pipe is buried at a certain depth underground, when the underground water level is higher than the pipeline in rainy season, the water can be discharged through the pipeline, and then the underground water level is controlled. The hidden pipe drainage solves the problem that open ditch drainage occupies farmland, but the manufacturing and burying costs are higher.

The northern China is a temperate zone monsoon climate region, rains are excessive in summer, drought frequently occurs in spring and autumn, and the rainfall in summer is about 70% of the rainfall in all the year. When the excessive rainfall in summer is drained along with the drainage ditch or the hidden pipe, the fresh water is lacked during irrigation in spring, autumn and winter, and particularly the crop planting and the grain production are seriously influenced by the lacked fresh water during sowing in spring. If the rainfall in the rainy season can be collected for spring and autumn winter irrigation, the utilization rate of rainfall resources can be greatly improved, and the grain yield and the water utilization efficiency can be improved.

At present, a rain collecting system is mostly carried out in a greenhouse, a greenhouse ceiling is used as a rain collecting surface, a flow guide device is arranged for collecting rain, and then warm irrigation is introduced, but the method can be carried out only under the condition that the greenhouse is available. There are also methods of digging a rain collecting pit separately or arranging a large rain collecting barrel on the ground, but this method occupies land resources. In the saline-alkali area, the farmland has only drainage facilities and does not have equipment for draining water and collecting rain.
