河北省盐碱地综合利用的现状、问题及建议
Current situation,problems,and suggestions for comprehensive utilization of saline-alkali soil in Hebei Province
摘要
Abstract
Saline-alkali land is becoming one of the most important potential farmland resources to guarantee national food security as the population increases.As one of the 13 major grain-producing areas in China,Hebei Province has three types of saline-alkali soil—coastal saline-alkali soil,saline-alkali soil in the Huang-Huai-Hai Plain,and saline-alkali soil in inland arid areas.These are a typical representative of saline-alkali soil in China with an area of 3.89×105 hm2.Therefore,it is of great significance for implement a food security strategy and the development of characteristic agriculture in the saline-alkali land region to study the comprehensive utilization of saline-alkali land in Hebei Province.Based on data from the second and third soil surveys on saline-alkali land and the published data,this study comprehensively analyzed the changes,current situation,problems,and development paths of the compre-hensive utilization of saline-alkali land in Hebei Province.Over the past 40 years,the area of saline-alkali land in Hebei Province has demonstrated a significantly decreasing trend,with a rate of decrease of 68.52%.Before 2011,most of the decreased area of saline-alkali land was mild saline-alkali land with an area of 2.377×105 hm2;however,the moderate and heavy saline-alkali land signific-antly decreased in area after 2011,with an area of 1.111×105 hm2.And,the areas of saline-alkali land in Zhangjiakou City and Hengshui City have decreased by relatively large margins,which were 2.33×105 and 1.12×105 hm2,respectively.However,the areas of saline-alkali land in Cangzhou City and Tangshan City have decreased by relatively small amounts,which were 3.37×104 and 2.49×104 hm2,respectively.The comprehensive utilization of saline-alkali land in Hebei Province has improved over the past 40 years with the development of new technologies.New salt-tolerant crop varieties,including winter wheat and alfalfa,have been developed.Researchers have developed the joint utilization of multiple water sources in farmlands,including rainfall,shallow brackish water,and soil water.Soil quality improvement technologies,including straw return with organic fertilizer application,construction of fer-tile cultivation layers,specialized fertilizers,and specialized equipment,have been developed.The joint application of new varieties,technologies,products,and equipment to various types of saline-alkali lands has significantly improved the soil quality of saline-alkali farmlands and crop production capacity.With the implementation of the major strategy of national food security,coordinated development of the Beijing-Tianjin-Hebei region,and the increasing demand for quality of life,there is an urgent need for the com-prehensive utilization of technology for saline-alkali lands.However,the maturity and penetration of comprehensive utilization tech-nologies for different saline-alkali land regions,policy continuity,comprehensive utilization technology,research and development potential,and promotion of varieties still need to be improved.There is also an urgent need to develop saline-alkali land characterist-ic industries that would benefit farmers'income and sustainable agricultural development.Given the current food requirements and the distribution and area of saline-alkali land,modern technologies for their utilization have been developed,and corresponding coun-termeasures and suggestions were put forward from various avenues of politics,industry,academia,research,and finance in this paper.关键词
