The invention provides an efficient water-saving communicating vessel irrigation water source system, relates to the field of agriculture and forestry irrigation, and aims to provide a water source solution for efficient water-saving irrigation. According to the solution, on the basis of the communicating vessel principle, finite water source points are transferred and copied according to required irrigation positions and the number, and the large grid-shaped communicating vessel irrigation water source system composed of a reservoir, a pipe network and a multifunctional water taking device is built in an engineering method. The efficient water-saving communicating vessel irrigation water source system is characterized in that non-power water conveying, automatic non-power water transferring and automatic pollution discharge can be achieved; the system is composed of independent system units which can constitute a large-scale irrigation water source network. By means of the solution, water sources can be completely and conveniently provided for efficient water-saving irrigation with low cost.

The invention discloses a sandy farmland water conservation method in the technical field of sandy land remediation. The specific steps of the method include in-situ stripping of topsoil, drilling holes, placing anti-seepage bags, covering the holes for water collection, The combination of hole making, anti-seepage bag planting measures and film mulching measures around the hole forms a soil profile spatial structure in which the underground local water barrier and the surface local catchment are coupled in dry farmland, which can reduce the leakage of precipitation into the deep soil. At the same time, the precipitation is collected to the crop planting area, and the collected rainwater is stored in the soil layer around the root system in the middle and lower parts, which is conducive to reducing surface evaporation and ensuring the water demand of crops during drought, thereby reducing the decline in crop yield caused by drought. To achieve better water and fertilizer retention effect, at the same time, the materials used are all degradable materials, and solid wastes such as straw can also be effectively used.

The invention discloses a non-fired water absorbing pillar for water supply of nursery stock and its production method, and belongs to the technical field of building materials of forestry. The non-fired water absorbing pillar is prepared from, by weight, 60-70 parts of tile powder, 25-30 parts of Portland cement, 1.0-2.0 parts of waste and old cotton, 5-10 parts of saw dust, 1-5 parts of leaf powder, 1-5 parts of hay meal, and 35-40 parts of water. The tile powder comprises fine tile powder and coarse tile powder; the dosage ratio of the tile powder and coarse tile powder is 1: 2.35-2.87. The non-fired water absorbing pillar provided by the invention is formed by adding water to waste tile gravel, waste and oil cotton, ordinary Portland cement, saw dust, tree leaf, and dry grass, mixing and extruding the raw materials; the waste tile and the waste cotton are main raw materials; the non-fired water absorbing pillar has the advantages of waste use and environmental protection.

The invention discloses a heat insulation culvert pipe system between internal lines in a railway station and a burial and construction method. The heat insulation culvert pipe system comprises a heat insulation culvert pipe and a protective culvert pipe. The heat insulation culvert pipe is buried below two adjacent existing lines. The protective culvert pipe stretches over the existing lines and is buried below the existing lines. One end of the heat insulation culvert pipe is connected with the protective culvert pipe. The other end of the heat insulation culvert pipe is connected with a platform to which water is to be supplied. The heat insulation culvert pipe and the protective culvert pipe are internally provided with a water supply pipeline, a drainage pipeline and heat supply pipelines. The burial and construction method comprises the steps of erection of a D-shaped beam, jacking construction of the protective culvert pipe, excavation of a pipe ditch between the existing lines, installation of the heat insulation culvert pipe, installation of the water supply pipeline, the drainage pipeline and the heat supply pipelines and burial completion. According to the heat insulation culvert pipe system, the heat insulation culvert pipe and the protective culvert pipe are laid below the existing lines, supplied water is successfully led into the platform to which the water is to be supplied, the water supplement capacity to passenger trains can be enhanced, input of manpower, materials and equipment is reduced, and it is guaranteed that railway transport is fast and unobstructed; by means of the construction method, the construction period is shortened, the working efficiency is improved, and safety and reliability are achieved.

The invention relates to a method for solving the salt deposition of a conical evaporator, which relates to the technical field of solar seawater desalination. The purpose of the present invention is to solve the problem that the existing conical evaporator is prone to salt deposition, which leads to a decrease in evaporation rate and cannot realize long-term continuous and stable operation in the seawater desalination process. Method: place the cylindrical thermal insulation device on the surface of seawater, ensure that one end of the hydrophilic water guiding device is immersed in the seawater, and then wrap the hydrophilic fiber material on the circumferential surface of the cylindrical thermal insulation device and stick it tightly At the same time, one end of the hydrophilic fiber material is uniformly distributed on the upper edge of the conical light-to-heat conversion film, and the other end of the hydrophilic fiber material is immersed in seawater to realize the in-situ anti-salt deposition function of the conical evaporator . The invention can obtain a method for solving the salt deposition of the conical evaporator.

The invention provides a soil water ecological effectiveness control method; the operation steps comprise that bacterial manure base material and bacterial cellulose are prepared and mixed into water ecological effective bacterial manure base material, and the water ecological effective bacterial manure base material is prepared into water ecological effective bacterial manure serum and the serumis sprayed on the soil surface; and then protective serum is sprayed, the soil is turned over after 5 to 7 days, and the water ecological effective bacterial manure serum and the protective serum aresprayed again; and the soil is turned over and leveled after 5 to 7 days. The soil water ecological effectiveness control method has the advantages of very significant control effect to the soil water characteristics, high-efficiency mechanical implementation, lower integrated cost, convenient operation and easy large-area implementation and promotion, and is mainly used for improving the water characteristics of the soil.

The application relates to the technical field of soil improvement, and specifically discloses a soil conditioner for planting seedlings and a method for using the same. A soil conditioner for seedling planting comprises the following raw materials: sucrose solution, superabsorbent resin and clear water. The use method comprises the following steps: taking the soil where the seedlings grow and mixing the sucrose solution in proportion to form mud; digging out the root system of the seedlings completely, wrapping the root systems of the seedlings with mud, and then planting the seedlings wrapped in mud back to the original place; The superabsorbent resin is buried in the roots of the seedlings, and then the soil balls are dug out, tied tightly with grass ropes, poured with clean water, and then transported after the soil balls and seedlings are loaded on the truck; after transporting to the destination, the soil balls are buried, and the The nutrient is evenly sprinkled on the soil at the roots of the seedlings, and then water is poured on the roots of the seedlings. The soil improver for planting seedlings and its use method of the present application can be used to improve the soil in the transplanting process of seedlings, and has the advantages of regulating the activity of seedlings and continuous water supply.
