| 摘要: |
| 采用小四轮拖拉机，铁牛－６５０和ＪＬ－１０６５联合收获机在松软的春小麦种床上压地１遍，苗期测定基本苗，生物量和播深一致性，收获后测定产量等，与免压处理进行比较，结果表明，在干旱的气象条件下，３种压实处理的春小麦产量分别比兔压处理低，６．２８％，２１．４４％和２３．３７％，农业机械造成的土壤压实验对春小麦生产发育的不利影响十分明显。 |

| Effects of Soil Compaction on Spring Wheat Growth |

| Abstract: |
| Small wheeled tractor, Tieniu-650 tractor and JL-1065 combine harvester were used respectively to compact the freshly tilled soil before drilling spring wheat. The plant population, biomass, uniformity of crop establishment and grain yield after these treatments were measured and compared with those in uncompacted treatment. The results showed that in drought growing season, the grain yield of compacting treatments were reduced by6. 28%, 21. 44% and 23. 37% respectively than that of the unwheeled treatment. The effects of soil compaction by the agricultural machinery on the growth of spring wheat is very harmful. |
