摘要
为了进一步提高玉米产量,以玉米庆单3号为供试品种,于2016年在黑龙江八一农垦大学试验实习基地进行试验,在喷施叶面肥黄金宝一号条件下,设置了3个处理,分别为CK:不喷施叶面肥;A1:喷施叶面肥浓度为0.150%,兑水300kg·hm^(-2);A2:喷施叶面肥浓度为0.107%,兑水300kg·hm^(-2),研究叶面肥对玉米叶绿素、干物质及产量的影响。结果表明:玉米喷施叶面肥黄金宝一号后,在一定范围内,可增加叶绿素含量,提高光能利用率与光能转化率;光合速率增强,延缓叶片衰老,可增加干物质积累的数量和质量;玉米穗行数、行粒数和百粒重也分别增加了0.2~0.4行、3.3~3.4粒和0.89~1.40g,其产量与对照CK相比多增产540.39~99.48kg·hm^(-2)。玉米喷施叶面肥黄金宝一号后可增加叶面积和提高叶绿素含量,促进玉米增产。
In order to further increase the yield of maize, taking the maize Qingdan3 as the experimental variety, the influences of leaf fertilizer to chlorophyll, dry matter and yield of maize under the condition of spraying leaf fertilizer Huangjinbao 1 were studied. The experiment was carried out at the experimental practice base of Heilongjiang Bayi Agricultural University in 2016,and three groups were set including CK： Non-spraying of leaf fertilizer; AI： Spraying of leaf fertilizer about 0. 150% with water mixed about 300 kg·hm^-2 ; A2.. Spraying of leaf fertilizer about 0. 107% with water mixed about 300 kg·hm^-2 . The results showed that after leaf fertilizer Huangjinbao 1 sprayed on the maize,it could increase the chlorophyll content,improve the efficiency for solar energy utilization and conversion efficiency to solar radiation, enhance the photosynthetic rate,delay leaf senescence,increase the cumulative quantity and quality of dry matters; the rows per ear, grains per row and 100- grain weight were increased 0.2～0.4 rows,3.3～3.4 grains and 0.89～1.40 g respectively. Compared with CK,the final yield of the maize was increased by 540. 4 ～ 699. 5 kg· hm^-2. After spraying leaf fertilizer H uangjinbao 1 on the maize,it could increase the leaf area and chlorophyll content,promote the yield of maize.
