种植密度对鲜食玉米遵糯4号的产量及性状的影响

摘要

The ridomized block design was adopted to study the inlfuences of different planting densities on yield and traits of fresh edible maize variety Zunnuo No.4. The results indicated that with increasing planting density, plant height, ear height, barren tip and fresh ear number all increased, while yield of fresh ear and number of commodity ear increased ifrstly and then decreased. Comprehensively considering, choosing planting density of 60000 plants/hm2 is beneficial for the plant growth, thus increasing yield and number of commodity ear of Znunuo No.4.%运用随机区组设计，研究了不同种植密度对鲜食玉米遵糯4号产量及其性状的影响。结果表明：株高、穗位高、秃尖、鲜穗数均随种植密度增加而增加；穗粗、穗长、穗行数、商品穗率均随种植密度增加而减小；而鲜穗产量、商品穗数则随种植密度增加先升后降。综合考虑，选择种植密度为60000株/hm2，这样有利于植株的生长发育，从而提高鲜食玉米遵糯4号的产量及商品穗数。
