| 摘 要： | 针对江苏沿海地区连作障碍现状，进行了棉花-水稻轮作耕作模式研究。结果表明棉花-水稻轮作可以改善土壤理化性状，大幅度地提高土地产出率，旱改水第一茬水稻比连作水稻增产17．5％，1hm^2农田纯收益增加2736元；同时减少农药使用，减轻农业面源污染，具有明显的经济和生态效益。

| Abstract: | The cultivation pattern of paddy-upland rotation(two kinds of crops employed,rice and cotton)was studied due to continuous cropping drawback in coastal area of Jiangsu Province.Cotton-rice rotation not only improved the soil physical and chemical properties,notably enhanced the land productivity,but reduced the pesticide application so as to alleviate the agricultural pollution.Compared to the continuous cropping pattern,the yield of rice grown in cotton-rice rotation system was increased by 17.5%,which inc... |
