摘要
本研究于１９９３年采用掖单１３玉米和克山白马铃薯，间套种与清种（ＣＫ）；１９９４年用掖单１３玉米品种分５２５００、６００００、６７５００株／公顷３个处理。在主要发育期观测玉米冠层热平衡方程中净辐射（Ｒｎ）、土壤热通量（Ｇ）、显热通量（Ｈ）、潜热通量（ＬＥ）的变化特点，及其对玉米干生物量和产量、效益等的影响。热平衡方程中各分量随栽培方式、密度和气候条件的不同而变化。
Maize Cultivar Ycdan No. 13 and Potato Cultivar Kcsanbai wcrc plantcd with inter-croping and monoculture in 1993. Yedan No. 13 was planted with three dcnsitics (52500, 60000, 67500 plants/ha) in 1994. At the main growth stage, the varibles in the heat balance equation of maize canopy were investigated. These varibles included Net Radiation (Rn),Soil Heat Flux (G),Sensible Heat Flux(H),Lattent Heat Flux (LE). Their influnces on dry biomass,yield and profit of Maize were studied. The values of the varibles in the heat balance equation changed with cultivated techniques,crop densities and weather conditions.
