中文摘要：试验旨在研究不同收获期对粤西地区青贮玉米农艺性状的影响。选用雅玉青贮8号、文玉3号、曲辰19号和北农青贮356共4种青贮玉米为原料,在雄穗开花后5(t1)、10(t2)、15(t3)、20(t4)、25(t5)、30(t6)、35(t7)、40 d(t8)时收割,测定农艺性状。结果表明,收获期相同时,雅玉青贮8号、文玉3号和曲辰19号的农艺性状较好;随着收获期延长,4种青贮玉米在t5、t6、t7时茎粗、茎重较优,在t5、t6时叶片重明显高于其他时间点,各青贮玉米的穗重和籽粒重呈先增加后减少趋势;4种青贮玉米的鲜重产量在t4、t5、t6时较高。研究表明,4种青贮玉米在t5、t6时的茎重达到最大,株高及穗部性状趋于稳定,产量较高,此阶段适宜收获。

外文摘要：The study was to explore the effect of harvest period on agronomic traits in western Guangdong.Four kinds of silage maize(Yayu silage No.8,Wenyu No.3,Quchen No.19 and Beinong silage 356)were selected as raw materials and harvested at 5(t1),10(t2),15(t3),20(t4),25(t5),30(t6),35(t7)and 40 d(t8)after male panicle flowering to determine the agronomic traits.The results showed at the same time,the agronomic traits of Yayu silage No.8,Wenyu No.3,and Quchen No.19 were better;with the extension of harvest period,the stem diameter and stem weight of four kinds of silage corn were higher at t5,t6 and t7,and the leaf weight at t5 and t6 was obviously higher than that of other time points.The ear weight and grian weight increased first and then decreased,the fresh weight yield of the four silage maize varieties was higher at t4,t5 and t6.The study indicates the stem weight of silage maize reached the maximum at t5 and t6,the plant height and ear traits tend to be stable,and the yield was higher,which are better for harvesting.
