Bionic Design of Furrow Opener Based on Muskrat Claw-Toe Structure to Improve the Operating Performance of Deep Application of Liquid Fertilizer in Paddy Fields in Cold Region of China

The deep application of liquid fertilizer in paddy fields is a fertilization technique that applies near the root system field crops, which can effectively improve absorption rate crops and reduce amount applied. In cold regions China, soil return furrowing operation low, easily cause excessive leakage affect crop growth. Therefore, it difficult to popularize large areas. According characteristics China operating requirements high backfill low disturbance fertilizer, this paper designed bionic furrow opener based on claw-toe structure muskrat. study, an indoor bin test was conducted by constructing environment for fields. results showed effects key parameters design opener, spraying pressure speed resistance, fertilizer. has when 0.8 m s−1, 0.2 MPa. This significantly improves performance suitable region.
