| 摘 要： | 六年试验结果得出，玉米、小麦、大豆产量均轮作高于连作，其中，豆茬玉米六年平均产量５６１５．９０ｋｇ／ｈｍ＾２，连作玉米为４９０９．４２ｋｇ／ｈｍ＾２，二者之间达到１％极显著差异。麦茬麦六年平均产量１８７６．３５ｋｇ／ｈｍ＾２，豆茬麦在１５４０．７８ｋｇ／ｈｍ＾２，连作麦是１４１９．３７ｋｇ／ｈｍ＾２，三者之间达到１％极显著差异水平。麦茬豆六年平均产量１６１３．６３ｋｇ／ｈｍ＾２，油菜茬大豆１５７４ |

| Abstract: | The research shows that rotation yield of corn, wheat and soybean are more high than continuous cultivation in six years. Among them average yield of corn in soyben stubble is 5615.90 kg/hm~2, average yield of continuous cultivation corn is 4 909kg/hm~2, between two reach 1% significance difference level. Average yield of wheat in wheat stubble is 1 876.35 kg/hm~2, wheat yield in soybean stubble is 1540.78 kg/hm~2, yield of continuous cultivation wheat is 1419.37 kg/hm~2, among three reach 1% signicance difference level. Average yield of soybean in wheat stubble is 1613.63 kg/hm~2, soybean yield in cole stubble is 1574.64 kg/hm~2, yield of continuous cultivation soybean is 1428.06 kg/hm~2, among three reach 5% significance difficance level. |
