肥料与密度对春大麦干物重和产量的影响
|
摘要
以大麦新品种"蒙啤麦5号"为试验材料,研究了氮、磷、钾肥与密度互作对春大麦干物重和籽粒产量的影响.结果表明,在一定范围内,大麦干物重随施氮量的增加而增加,合理的施肥量与种植密度对大麦产量也有显著增产效果.本试验研究得出该品种大麦抽穗期干物重理论最大值为14499.67 kg/hm~2,相应的栽培措施是N 110.19 kg/hm~2、P_2O_5124.88 kg/hm~2、K_2O 77.29 kg/hm~2、密度594.53万株/hm~2.大麦籽粒产量理论最大值为6046.38 kg/hm~2,相应的栽培措施是N 108.92 kg/hm~2、P_2O_5124.63 kg/hm~2、K_2O 80.51 kg/hm~2、密度631.36万株/hm~2.
The effects of nitrogen,phosphorus,potassium fertilizer and density on dry matter weight and grain yield of a new barley variety"Mengpimai 5"were determined. In a certain range,the dry weight of barley increased with the increase in the amount of nitrogen applied. Reasonable fertilizer application and planting density also had a significant effect on barley production. The theoretical maximum value of dry matter weight at the heading stage of this variety of barley was found to be Ymax=14499.67 kg/hm~2,the corresponding cultivation measures N 110.19 kg/hm~2,P_2O_5124.88 kg/hm~2,K_2O 77.29 kg/hm~2,and the density 594.53 Million/hm~2. The maximum barley yield theory was found to be Ymax=6046.38 kg/hm~2,the corresponding cultivation measures N 108.92 kg/hm~2,P_2O_5124.63 kg/hm~2,K_2O 80.51 kg/hm~2,and density 631.36 Million/hm~2.
