摘要
为了探索冀西北雨养区春玉米单产提升技术,试验设置春玉米增密增肥处理、单施有机肥处理,以当地种植模式为对照,监测春玉米农艺性状、穗部及产量性状.结果表明,增密增肥处理增加了春玉米植株的秃尖率,降低了千粒重及穗粒数,较CK显著增产5.3%;单施有机肥处理增加了春玉米植株的穗粒数和千粒重,降低了秃尖率,较CK显著增产10.4%.2个处理的千粒重、产量与对照间均有显著差异.因此,增加密度、增施有机肥能提升雨养旱作区春玉米产量.
Abstract
In order to explore the techniques to improve the yield of spring corn in the rain-fed area of northwest Hebei Province,we set up treatments of density and fertilizer increasing treatment and single application of organic fertilizer treatment,with local planting patterns as the CK.The agronomic,ear and yield characters of spring corn were monitored.Results showed that density and fertilizer increasing treatment en-hanced the bald tip rate,reduced the 1 000-grain weight and ear per grains,and its yield enhanced by 5.3% significantly.Single application of organic fertilizer treatment enhanced the grains per ear and 1 000-grain weight,reduced the bald tip rate,and its yield enhanced by 10.4% significantly.Compared with CK,the 1 000-grain weight and yield of the two treatments had significant differences with those of CK.Thus,in-creasing planting density and fertilizer could enhance the yield of rain-fed spring corn in dry farming areas.
