| 中文摘要: |
| 通过田间小区随机区组试验，研究了不同耕作措施对冷浸田土壤亚铁量、水稻产量构成因素及产
量的影响。结果表明不同耕作措施对土壤亚铁量、水稻生物性状、产量构成因素均有不同影响。采取不同措施后
亚铁量消减了27.97%～44.86%，少耕处理的亚铁消减量最大、为393.35…mg/kg，其次是水旱轮作处理、消减量为451.88…
mg/kg；与农民习惯相比，少耕处理产量最大、为7…790…kg/hm2
，增产4.55%，其次是垄作处理，产量达7…764…kg/hm2
，增产
4.51%。 |
| 英文摘要: |
| A field plot randomized block experiment was conducted to study the effects of different tillage practiceson the ferrous iron of soil，rice yield components and rice yield in cold waterlogged paddy field. The results indicatedthat different tillage practices had different effects on the ferrous iron of soil，various biological traits of rice and yieldcomponents. The ferrous iron reduced by 27.97%-44.86% with different processing methods. The maximum reductionwas obtained in fewer-tillage processing by 393.35 mg/kg，and the treatment with paddy-upland rotation followed by451.88 mg/kg. Compared with farmer's practice，the practice of fewer-tillage led to the highest yield with 7 790 kg/hm2 andthe growth rate was 4.55%. The treatment with ridge tillage followed by 7 764 mg/kg and the growth rate was 4.51%. |
