基于WEB的棉花信息管理及施肥推荐决策支持系统建立研究

依据区域土壤肥力差异、作物需肥规律、土壤供肥性能与肥料效应等众多因素,以新疆兵团农五师81团为系统试行和合作地点,建立棉田土壤养分信息管理、施肥推荐模型,利用SQL JSP Win2000构建综合性、数字化和智能化的基于WEB的棉花信息管理及施肥推荐决策支持系统,实现了条田信息管理、智能化施肥决策和数据信息管理的有机耦合与集成。系统于2005—2006年在农五师81团等用户中应用推广,其中2006年应用面积2.87万hm2,平均皮棉单产1806kg,比前3年平均1683kg增产123kg,增产率7.3%,每公顷节约化肥投入成本114元,合计节本增效1584万元。

Study on WEB-based cotton fertilization recommendation and information management decision support system

Based on the regional difference in soil fertility,the nutrient uptake of crop,the nutrient supplying capacity of soil and the response of fertilizers,etc.,this study took the 81th regiment of the 5th agricultural division in Xinjiang Bingtuan as the training and cooperative region,and established the information system of soil nutrients for cotton fields and recommendation model of fertilization.Constructed comprehensive,digital,and intellectualized WEB-based cotton fertilization recommendation and information management decision support system by using SQL JSP Win2000.The system had been applied successfully in 2005 and 2006 there,and in 2006 the mean yield per hm2 increased by 7.3% than that of former 3 years,and the fertilizer cost per hm2 reduced 114 yuan(RMB).
