转蓝光长寿光转换多功能地膜对玉米生长发育的影响

分别采用功能地膜、普通地膜覆盖，分2行和3行两种种植方式，观测了各处理对河西绿洲灌区玉米生长发育的影响。结果表明，无论是种植2行还是3行玉米，转蓝光长寿光转换多功能地膜覆盖比普通地膜覆盖在玉米大喇叭口期耕层土壤温度高0～1．24℃。种植2行玉米时，功能地膜比普通地膜在玉米大喇叭口期0-40cm土层土壤水分低11．9～25．3g，kg，株高提高10．90％，玉米生物量提高20．57％，折合产量提高11．53％。种植3行玉米时，功能地膜覆盖比普通地膜覆盖在玉米大喇叭口期0--40cm土层土壤水分低6．5～18．2g／kg，株高提高7．80％，生物量提高34．23％；折合产量提高9．28％.

Effects of Light Transform Multifunctional Mulch Film of Convert Blue Light and Longevity on Growth Development of Corn

Two rows and three rows two kinds of planting mode respectively used functional mulch film and common plastic mulch film, the effects of each treatment on growth development of corn were observed in Hexi Oasis Irrigation. The results showed that whether planted two rows or three rows of corn, soil temperature of muhifunctional mulch film were higher by 0 - 1.24 ℃ over that of common plastic mulch film in the bell-mouthed period . When planting two rows of corn , 0 -40 cm soil moisture of muhifunctional mulch film were lower by 11.9 - 25.3 g/kg that of common plastic mulch film the bell-mouthed period, and the plant height, biomass, yield respectively increase by 10.90%, 20.57%, 11.53%, respectively. When planting three rows of corn, 0 - 40 cm soil moisture of muhifunctional mulch film were lower by 6.5 - 18.2 g/kg that of common plastic mulch film in full expansion leaves, and the plant height, biomass, yield respectively increase by 7.g%, 34.23%, 9.2g%, respectively.
