河南省沿黄稻麦区土壤培肥与水肥运筹中的几个突出性问题及其技术对策

Main Problem and Technical Countermeasures for the Management of Soil,Water and Fertilization under the Rotation System of Rice and Wheat along Yellow River in Henan Province

针对河南省沿黄稻麦轮作区近年土壤培肥和水肥运筹中的问题，提出实现稻麦持续均衡高产应采取的技术对策：（１）对症下药，消除障碍稻麦生育的主要土壤因子，培育持续均衡高产所必需的土壤；（２）组装现有土肥成果，配合稻麦栽培、植保等相关学科，加强技术示范和推广；（３）开展稻麦轮作区土壤培肥与均衡高产施肥和节水管理的系统研究。

Based on the investigation on the current situation of soil management and fertili zation under the rotation system of rice and wheat along Yellow River in Henan province,three technical countermeasures were put forward for attaining sustainable and balanced high yield of rice and wheat as follows:(1)removal of main factors being unfavor for the growth of rice and wheat to get the fertile soil which could ensure sustainable high yield of crops,(2)realignment of various concerning achievements,combining with other cultivated technique and strenthening the work of demonstration and popularization (3)systematical study on soil fertility and balanced high yield of rice and wheat under the rotation system of rice and wheat along Yollow River.
