| 摘 要： | 以丹玉39为试验材料,在3种不同种植形式(2比空、大垄双行和清种)和3种不同播种方式(双株定向种植、双株紧靠种植和单株种植)条件下,对春玉米光合特性变化与产量结果进行比较分析。结果表明,双株定向播种方式下净光合速率、气孔导度、胞间CO2浓度、蒸腾速率均较高,双株定向播种、大垄双行种植形式下净光合速率最高,为18.20μmol/(m2.s);双株定向播种、清种种植形式下产量最高,为10 786.50 kg/hm2,双株定向播种、大垄双行种植形式下产量次之,为10 260.00 kg/hm2。大垄双行与双株定向组合较清种与双株定向组合的光合速率更高,说明大垄双行的种植形式更有益于通风透光,提高光能利用率。

| Abstract: | Using Danyu39 as the experimental material,the comparison results between photosynthesis capacity and yield of spring maize with planting patterns(2-0 culture,double rows on a big ridge and single planting),sowing pattern(two-line orientation,two-line hug and individual planting) were analyzed.The results showed that there were higher photosynthetic rate,stomatal conductance,intercellular CO2 concentration and transpiration rate under the condition of two-line orientation cultivation,the photosynthetic rates reached the reached a highest value of 18.20 μmol/(m2·s) with two-line orientation cultivation and double rows on a big ridge cultivation.The highest value of yield was 10 786.50 kg/ha using two-line orientation cultivation and single planting cultivation,the production under two-line orientation cultivation and double rows on a big ridge cultivation took second place(10 260.00 kg/ha).These results provided the corroborative evidence of high yield of and high photosynthetic efficiency with two-line orientation cultivation and double rows on a big ridge cultivation. |
