This utility model provides a heat-insulating and water-storing tree fence, comprising: a moisture-retaining component, which includes several water collection tanks, each with a water collection cover on its upper surface and a water outlet at its bottom, the tanks arranged in a ring shape; and an insulation pad connected to the inner ring of the ring-shaped water tank. During construction, tree grates are placed around the base of the tree, and the fence is installed around the tree on the grates. The grates, in addition to preventing soil erosion and trampling, provide support for the fence. The combined components of this device provide protection for the tree, soil and water conservation, and heat and moisture retention. It is more aesthetically pleasing than traditional drip irrigation, and the water collection tanks collect rainwater, saving water resources. Rainwater replenishment further extends the moisture retention time.

The utility model discloses an ecological model of carbon loss and gain of grazing grassland ecosystem, which couples carbon loss caused by grazing, increase of soil organic carbon pool caused by animal excrement and carbon loss caused by animal trampling plant by establishing grazing carbon balance model and animal trampling carbon loss model, so as to obtain actual carbon loss and gain of grassland ecosystem. In the application, the utility model fully considers the factors of animal grazing, animal excretion and animal trampling in the whole grazing process, perfects the influence of disturbance factors of whole grassland ecosystem on vegetation, reduces the uncertainty of regional grassland carbon cycle simulation and improves the accuracy of results. Therefore, the utility model has high accuracy.

The invention discloses a boar feeding anti-treading detection device, and relates to the technical field of boar feeding, the boar feeding anti-treading detection device comprises a base and a feeding assembly installed on the top of the base, the top of the base is provided with a limiting piece, the top of the limiting piece is provided with a limiting groove, and a limiting plate is slidably inserted in the limiting groove; a first screw rod is rotationally arranged in the limiting piece, the first screw rod is sleeved with a first nut in a threaded mode, one end of the first nut penetrates through the limiting piece in a sliding mode and is fixedly connected with one side of the limiting plate, and a motor is arranged at the top of the limiting piece; a single boar is driven onto the base, then a motor is started, a first screw can be rotated, a first nut drives a limiting plate to move upwards in a limiting groove, the boar is made to approach the feed trough conveniently, then the limiting plate is put down according to the principle, and the single boar can be limited; and the problem of treading caused by crowding when a plurality of breeding pigs enter the ingestion area at the same time is avoided.
