丘陵区旱地两熟全程机械化玉米品种的鉴选

Maize Varieties Selection for Entire Mechanization and Two Cropping System in Hilly Rainfed Land

为鉴选出适宜西南丘陵区旱地两熟全程机械化种植的优良玉米品种,对近年来品种筛选试验中表现较突出的6个玉米品种,开展了全程机械化鉴选试验。结果显示,蠡玉16全生育期适中、产量高、播种质量好、出苗整齐、成穗率高、收获时籽粒含水率低、机收损失率低,较适宜丘陵区旱地两熟全程机械化种植。此外,正红505、国豪玉7号的综合表现也较好,可进一步研究利用。

To select qualified maize varieties for entire mechanization and two cropping system in southwest hilly rainfed land,6 maize varieties which had better overall performance in recent years,were selected tocarry out varieties selection by entire mechanization.The results showed that Liyu 16 is more appropriate variety for entire mechanizationand two cropping system in the southwest hilly rainfed land.It has moderate whole growing period,higher yields,better sowing quality,and better uniformity in emergence,highercob rate,lower grain water content and lower loss rate at harvest.In addition,Zhenghong 505 and Guohaoyu No.7 can be used further study,which hasrelatively good overall performance.
