| 摘 要： | 以“天紫22号”糯玉米为试材,于2009年夏季北京市郊农业园区蔬菜温室休闲期,模拟不同降雨条件,研究其对填闲作物糯玉米产量、根系生长和养分吸收的影响.结果表明:在不同降雨条件下,D-2和F-2处理鲜糯玉米产量分别达到13.4 t/hm2和13.3 t/hm2,产量差异不显著；F-2处理对氮、磷、钾养分吸收量均低于D-2处理,说明大量降水影响作物对养分的吸收；D-2处理各土层的根长密度和根系干重均高于F-2处理,说明适当干旱有助于根系生长和养分的吸收,减少土壤养分的流失.

| Abstract: | 'Tianzi No.22' waxy corn was used as test materials to study on the effect of simulated different rainfall on the yield,root growth and nutrient uptake of catch crop-waxy corn in vegetables greenhouse of outskirts agricultural park in Beijing in the summer fallow period in 2009.The results showed that differences was no significant of waxy-corn yield for D-2 and F-2 treatment under simulated different rainfall treatment,the fresh corn production reached 13.4 t/hm2 and 13.3 t/hm2;By comparison N,P and K upta... |
