摘要/Abstract

摘要： 本试验比较了31个玉米品种全株青贮的农艺性状和产能，以期筛选出适合在关中地区推广种植的优良青贮品种。结果表明，品种之间的农艺性状和产能均差异显著，其中生长时间最长的107 d，最短的87 d；叶片数最多的16.5片，最少的11.3片；株高最高的281.3 cm，最矮的199.5 cm；青贮产量最高的6.2吨·亩^-1，最低的2.1吨·亩^-1；干物质产量最高的1.8吨·亩^-1，最低的0.6吨·亩^-1。对产量最高的4个品种（‘DB08’、‘DK625’、‘JKQZ932’和‘HY36’）进行营养成分分析发现，除灰分之外，与对照粮饲兼用品种DZ12相比，它们的粗蛋白、粗纤维和粗脂肪含量存在显著性差异（P<0.05）。根据青贮产量和奶牛饲喂价值的需求，本文建议专用青贮玉米‘DB08’和‘DK625’适宜作为全株青贮玉米在关中地区进行大面积推广种植。

Abstract: In this study,31 corn varieties were tested for agronomic traits and production capacity as the whole plant silage to screen out suitable silage maize varieties for promotion in Guanzhong area. The results showed that their agronomic traits and productivity were significantly different,with the longest growth period of 107 days and the shortest 87 days;the maximum number of leaves was about 16.5 and the minimum was about 11.3;the highest plant height was about 281.3 cm,and the shortest was about 199.5 cm;the highest silage production was about 6.2 tons·mu^-1,the lowest was about 2.1 tons·mu^-1;the dry matter yield was the highest about 1.8 tons·mu^-1,the lowest was about 0.6 tons·mu^-1. Analysis of the nutrient contents of the four highest-yielding varieties (DB08、DK625、JKQZ932 and HY36) revealed that except ash,there was a significant difference (P<0.05) in their crude protein,crude fiber and crude fat content compared to the control varieties. According to silage production and requirements of the feeding value of dairy cows,we recommend that DB08 and DK625 are suitable for promotion as whole plant silage corn in Guanzhong area.
