Salt-resistant straw application device for saline-alkali soil

The saline-alkali soil straw salt-blocking application device comprises an I-shaped support and an agricultural machine body, the I-shaped support is fixedly connected with the agricultural machine body, a rotary plow is installed at the lower end of the agricultural machine body, an ingredient filling mechanism is arranged at the upper end of the I-shaped support, and an anti-blocking layer application mechanism is arranged at one end of the I-shaped support. And a main material storage mechanism is arranged above the I-shaped bracket. The device has the beneficial effects that straws can stably and efficiently fall into the soil under the action of the anti-blocking layer application mechanism to form a straw layer, so that the soil pore connectivity is destroyed to achieve the salt blocking effect; meanwhile, straw decomposition not only can increase the content of organic matters and the like in soil, but also can improve the soil structure; by optimizing the application structure near the plow pole, the
