聊玉23号简化栽培增产增效技术集成研究

开展聊玉23号机械单粒播种方式、机收时期、氮磷钾肥配比、"一防双减"、种肥同播和籽粒灌浆特性的试验,结果表明应按75 000粒/hm~2机械单粒播种,播种后105~110 d机械收获,氮磷钾肥配比2∶1∶2,授粉结束后用直升机喷施混合药剂防治后期病虫害,用玉米专用控释肥600 kg/hm~2种肥同播,吐丝51 d后的灌浆速率、脱水速率明显变小。从做好备播工作、机械单粒播种、种肥同播、节水灌溉、综合防治病虫草害和机械适期收获等方面介绍了聊玉23号简化栽培增产增效技术。

Study on Technology Integration of Increasing Yield and Benefit for Liaoyu 23 Simplified Cultivation

The study carried out the test of mechanical single grain sowing way,mechanical harvesting period,the ratio of NPK fertilizer,spraying way,seed manure simulcasting,grain filling properties for Liaoyu23.The results showed that we should take mechanical single grain sowing way according to 75 000 grains/hm2,mechanical harvest after sowing 105-110 days,apply the ratio of NPK fertilizer 2:1:2,use helicopters spraying mixed medicament control plant diseases and insect pests in the later period after pollination,seed manure simulcast by using the special controlled release fertilizer 600 kg/hm2 for corn.In those cases,grouting rate and dehydration rate decreased significantly after spinning 51 days.The technology of increasing yield and benefit for Liaoyu23 simplified cultivation was introduced from the aspects of preparatory work,mechanical single grain sowing,seed manure simulcasting,water-saving irrigation,disease pest and weed comprehensive prevention,mechanical harvesting in time.
