| 摘 要： | 为寻求青贮玉米栽培中性状改良、产量升高的新途径和新技术,在贵州松桃县九江乡试验地以青贮玉米(郑青贮1号、豫青贮23)和拉巴豆为研究材料,于青贮玉米行距间套种不同行数的拉巴豆,共设3个处理玉米不套作、一行玉米+一行拉巴豆、一行玉米+两行拉巴豆,研究多行拉巴豆套种对青贮玉米农艺性状和产量的影响。结果表明,青贮玉米行间套种两行拉巴豆时青贮玉米产量最高,郑青贮1号产量达55350.00 kg·hm-2,豫青贮23产量达75410.71 kg·hm-2;套种一行拉巴豆时株高最高,但豫青贮23的产量、株高均优于郑青贮1号,分别高达62013.89 kg·hm-2和298.99 cm;随着套种拉巴豆行数的增加郑青贮1号农艺性状指标叶长增大,叶宽和穗数减小,而豫青贮23的农艺性状指标变异正好相反;郑青贮1号套种两行拉巴豆时穗长最长达37.24 cm,而豫青贮23不套种拉巴豆时穗长最长达43.57 cm;变异分析中,两个青贮玉米品种产量和穗数均是变异较大,达到17%以上;套种两行拉巴豆时的郑青贮1号收入最高可达29335.50元·hm-2,豫青贮23收入最高可达38664.76元·hm-2,豫青贮23的经济效益要显著优于郑青贮1号。

| Abstract: | This research investigated intercropping of two varieties of silage maize (‘Zheng Silage No. 1’ and ‘Yu silage 23’) with Dolichos lablab with the aim of developing new methods to improve the agronomic traits and yield of silage maize. The experiment was carried out at Jiujiang Township, Songtao County, Guizhou Province, and included three treatments: silage maize with no intercropping, alternate rows of silage maize of D. lablab, and two rows of D. lablab between each row of silage maize. The yield of silage maize was higher for ‘Yu silage 23’ than for ‘Zheng silage No.1’ in all planting regimes and for both varieties yield was highest when interplanted with two rows of D. lablab between each row of maize, (55350 and 75411 kg·ha-1 FM for ‘Zheng silage No.1’ and ‘Yu silage 23’, respectively), and lowest for the monoculture, with the one-row D. lablab interplanting regime having intermediate yield. The plant height was highest (299 cm for ‘Yu silage 23’) when intercropping one row of D. lablab, but yield was reduced compared to two-row intercropping (62014kg·ha-1 FM for ‘Yu silage 23’). The leaf length of the agronomic character index of ‘Zheng silage No.1’ increased with the increase in the number of D. lablab interplanting lines, the leaf width and the panicle number decreased, but the variation of the agronomic traits of ‘Yu silage 23’ was just the opposite. The panicle length of ‘Zheng silage No.1’ was 37.24 cm when interplanted with two rows of D. lablab, while that of ‘Yu silage 23’ when not interplanted with D. lablab was 43.57 cm. In variation analysis, the yield and panicle number of two silage maize varieties were larger than 17%. The maximum income from ‘Zheng silage No.1’ and ‘Yu silage 23’ was calculated as 29336and 38 665 CNY·ha-1, respectively. Thus, the economic benefit of ‘Yu silage 23’ is significantly better than ‘Zheng silage No.1’, and interplanting with two rows of D. lablab per row of maize is recommended. |
