| 摘 要： | 试验表明,吉林西部苏打盐碱地实施鱼麦轮作模式效益显著,平均鱼产量2 793.3 kg/hm2,小麦产量3 197.6 kg/hm2,平均净收入8 686元/hm2,产投比为2.491。2个生长期0 cm~20 cm土层平均减少盐分8 179.2 kg/hm2,随排水排出系统的盐分约7 200 kg/hm2,土壤含盐量平均下降69.6%,土壤有机质、全量氮、全量磷分别增加了201.7%、46.0%及40.0%。鱼麦轮作模式不会造成土壤次生盐碱化,可在同类地区的农业综合开发中推广应用。表3,参6。

| Abstract: | The experiment showed that the rotation of fish and wheat pattern in saline sodic land of the west of Jilin Province in China has a significant benefit.The average yields of fish and wheat are 2 793.3 kg/hm~2 and 3 197.6 kg/hm~2,respectively.The average net income is 8 686 yuan(RMB)/hm~2,and the ratio of output and input is 2.491 in the experimental area.The total amount of salt of 8 179.2 kg/hm~2 has been cut down in the soil bed from 0 to 20 cm,and the amount of salt drained away is about 7 200 kg/hm~2 with water at two growth periods.Total salt decreased by 69.6%,and organic matter of soil,total N and total P increased by 201.7%,46.0% and 40.0%,respectively.This pattern can be used to comprehensive agricultural development in the same kinds of saline sodic land of other areas. |
