摘要：

In order to explore the influence of different agricultural tires on soil compaction in northeast black soil area, explore effective ways to reduce soil compaction, improve farmland ecology and protect black land, typical black soil cultivated land in northeast China was taken as object, and field operation comparative experiments were carried out based on different agricultural tires in the link of corn seeding. Two types of agricultural tires, ultra-low pressure radial tire and ordinary radial tire, were set up in the experiment. Four key soil physical property parameters, namely soil compactness, soil moisture content, soil bulk density and soil porosity, were calculated by scientific sampling method. On this basis, a comprehensive evaluation model of soil compaction was established based on CRITIC - Entropy weight method, and the soil compaction status of ordinary radial tire ( CK) and ultra-low pressure radial tire ( VF) at depth of 5 cm, 10 cm, 15 cm and 20 cm was evaluated statistically. The test results showed that in 0 ~ 20 cm soil depth, compared with radial tire, ultra-low pressure radial tire reduced soil compactness by 11. 38%, 7. 97%, 5. 36% and 4. 55%, and increased soil moisture content by 11. 06%, 10. 07%, 7.37% and 5.95%, respectively. Soil bulk density was reduced by 3.71%, 3.81%, 3. 12% and 2. 73%, and soil porosity was increased by 11. 13%, 12. 25%, 8. 92% and 5. 86%, respectively. The soil comprehensive evaluation scores of different treatments in descending order were VF5, VF10, CK5, VF15, CK10, VF20, CK15, CK20, indicating that under the same conditions, the soil comprehensive condition of compacting ultra-low pressure radial tire was better than that of ordinary radial tire. The results showed that ultra-low pressure radial tire had positive effects on reducing compaction of black soil and maintaining soil physical environment, which was helpful to protect black soil and ensure national food security. © 2023 Chinese Society of Agricultural Machinery.
