东北苏打盐碱地生态渔业模式研究

Eeo-fishery model in soda saline-alkaline land of northeast China

  • 摘要: 试验结果表明,东北苏打盐碱地实施鱼一稻一苇一蒲生态渔业模式效益显著,平均单产水稻为6024.2kg/hm2 、芦苇8336.2kg/hm2 和蒲草7387.6kg/hm2;平均鱼产量稻田养鱼为912.Ikg/hm2 、蒲塘养鱼3537kg/hm2 和苇塘养鱼2766k/hm2;平均净收入5667,l元/hm2 ,产投比为2.074。1个生长期节水1.9万m3/hm2 ,节约化肥290kg/hm2,降低土壤盐分507kg/hm2

     

    Abstract: The exDeriments show that eco-fishery pattern of fish-rice-reed-cattail in soda saline-alkaline land of northeast China has a significant benefit.The average yields of rice grain,reed and cattail are 6024.2kg/hm2,8336.2kg/hm2and 7387.6kg/hm2,respectively,and the average fish yields are 912.1kg/hm2 ,3537kg/hm2and 2766kg/hm2 in paddy fields,reed ponds and cattail ponds,respectively.The average net income is 5667.1 yuan(RMB)/hm2 and the ratio ofoutput and input is 2.074 in the experimc ntal area.19000m 3/hm2 of water and 290kg/hm2 of chemical fertilizer can be sayeel,respec-tively,and the total amount of the salinity of 507kg/hm2 has been cut down at a growth period.
