黄淮海平原豫北土地风沙化对土壤肥力的影响

Effect of Sandification on Soil Fertility in North Henan Province on Huang-Hui-Hai Plain

对风沙化引起的土壤机械组成、持水能力、容重和空隙度、土壤化学性质及对土地生产力的影响等方面进行了详细的论述。在此基础上 ,提出风沙化土地的整治要以防护体系的建设为前提 ,以发展水利为保证 ,以增施化肥 ,秸秆还田等措施提高地力为关键。

This paper analyzed the characteristic and process of land sandification in north Henan province, detailedly expounded the effect of sandification on soil mechanical composition, bulk density, total porosity, soil chemistry and land productivity, and put forward that the premise of harnessing land sandification is to establish wind break system, the ensurance is to develop water conservancy, the key is to increase fertilizer and to return crop remains.
