摘要:
为选出适宜贵州省种植的全株青贮玉米(Zea mays L.)品种(系),对7个玉米品种(系)进行引种生产性能比较试验,并探讨其各农艺性状与产量、品质的相关关系。结果表明,在生物学产量方面,以青丰4号表现最好,鲜质量和干质量分别达到64.68、19.28 t/hm2;在品质方面,粗蛋白、粗脂肪等含量以青丰4号最高,分别为8.07%、463%,显著高于其他各品种(系)(除对照组外)(P<0.05),粗纤维含量以红单10号最低,显著低于其他各品种(系)(P<0.05)。农艺性状与产量、品质有一定程度的相关性,生物学产量与叶片数、株高、茎粗、穗位高、穗质量均呈显著正相关关系(P<0.01);叶片数、叶长、叶宽与粗蛋白含量均呈显著正相关关系(P<0.05);叶片数、叶长、叶宽与粗脂肪、粗灰分含量均呈正相关关系,但不显著;叶片数、叶长与粗纤维含量均呈显著负相关(P<0.05)。从生物学产量及营养品质2个方面综合评定,以青丰4号表现最为良好,适宜在贵州省推广种植。
