黑龙江省半湿润区玉米高密度超高产综合技术研究初报

Preliminary Report of the Comprehensive Technical Research of High Density and Super High Yield of Maize in the Half Moist District of Heilongjiang

研究了玉米高密度压力下的品种筛选、合理密度、田间种植方式、配方施肥方案。结果表明,玉米新品种江203、龙单26、吉单27、东农250、吉高2、龙单25适合该区种植,且江203、龙单25、龙单26分别在20 cm2、5 cm3、0 cm密度水平下产量最高;所选择的5种田间种植方式中以2比空模式产量最高,产量为827.08 kg/667m2;配方施肥也达到了预期效果。

The study on prescription apply fertilizer scheme, reasonable density, field planting way and the selection of the rarity under high density. Results showed that new corn kind jiang203, longdan26, jidan27, dongnong250, jigao2 and longdan25 suit this district to plant , and jiang203, longdan25 and longdan26 have highest output under the density level of 20 cm ,25 cm and 30 era;In the 5 kinds of field planting way, the yield of 2 to zero pattern is highest, the yield is the 827.08 kg/667m^2 ;Prescription apply fertilizer scheme also reach expected effect.
