汉沽农场就海水倒灌后如何种稻问题 ,提出了一整套补救措施 ,即全部清排毛 ;用辅助水源井淡水洗盐压碱 ;增施磷肥和酸性肥料 ;监测不同地块的水质及时排灌 ;加强田间管理 ;充分利用回归水等。通过以上措施使公顷产量达 750 0kg以上 ,与正常年份持平。同时对海水倒灌后土壤的水盐动态进行了观测 ,总结出了换水后土壤氯离子随时间的推移而减少的规律。提出了水稻返青期和分蘖期的耐盐极限
Put forward a set of remedial measures to solve the problem of how to grow rice after seawater intrusion in Hangu Farm, that is, to clean all wool; to wash salt and alkali with fresh water from auxiliary water source wells; to add phosphate fertilizer and acid fertilizer; to monitor irrigation and drainage of water in different plots timely; Strengthen field management; make full use of return water. Through the above measures, the output of hectare will reach over 750kg, which is the same as that of the normal year. At the same time, the water and salt dynamics of the soil after the seawater intrusion were observed, and the law of the soil chloride ion decreasing with the passage of time was summarized. The salt tolerance of rice during turning-back and tillering stages was proposed
