摘　　要：在冀东北两茬积温不足地区，以两茬作物持续高产高效为目标，利用农业生态学原理，采用定点、单项、组合优化和示范重演等方法，通过作物种植模式的改良，提高环境资源的转化率及系统生产率。经过３ａ的研究，提出了以两茬套种持续高产高效为特点的种植模式。与当地习惯的带田套种和两茬复种比较，生育期间积温增加３４６．２～３８４．９℃，光能利用率分别提高０．３１％和０．１４％，产量分别提高３１．０％和１９．０％。产值分别增加２７．８０％和１３．６５％，为该区“两高一优”农业的建设提供了栽培管理技术依据。In two-crop infficient cumulative temperature areas of northeast Hebei,for the aimof continuous high prodution and high efficiency of two-crop Strains, Utilizing agricecol-ogy theories,adopting the means of fixed places, single item,combinatorial optinizationdemonstration。repeating and so on,we could raise transition probability and system pro-ductivity of enviromental resources by improving strain planting pattern. Through thestuolip for 3 years,put forward the planting pattern with the characteritios of continuonshigh production and high efficiency of two,crop interplanting. Compared with the localconventional interplant and two-crop multiple cropping,during the growth period,cumulatime temperature increased 346.2～384.9℃, efficiencies of light energy utilizationwere raised 0. 31%and 0. 14%respectively,the outputs were improved 31.0%and 19.O%respectively,output value were increased 27.8%and 13. 65%respectively. It provided reasons for cuItivation n1anagement technogy in the local“high prodaction,high effi-cency and the optinllzation”agricuItural construction.
