松嫩平原稻区防止次生盐渍化的研究

PREVENT SECONDARY SALINIZATION IN SONGNEN PLAIN

松嫩平原种稻区防止土壤次生盐渍化技术研究表明 ,合理灌溉、加强排水、增施有机肥、调控水盐平衡和肥盐平衡 ,是农业生产中的一个重要问题。通过旱改水种稻治涝防止土壤次生盐渍化技术的研究 ,明确了井灌、渠灌。

Through researching the technology of prerent secondary salinization in Songnen Plain,indicates that rational irrigation reinforce drain off water,increase using organic fertilizer,regulate the balance between water and salt or the balance between salt and fertilizer,which is an important question in Agricalturd produce.By researching the technology that change the dry farmland to paddy field and grow rice to prevent secondory salinization,it makes clear the influence of well irrigation,canal irrigation,and well-canal irrigation to soil secondary salinization.
