摘要
为探究等带宽条件下玉米/秋马铃薯不同间作行比对秋季马铃薯生长及遮阴效果的影响,筛选出适合中原二作区特别是鲁西南地区推广应用的玉米/秋马铃薯间作模式,设计T1(玉米/秋马铃薯=1/1)、T2(玉米/秋马铃薯=1/2)、T3(玉米/秋马铃薯=1/3)、T4(玉米/秋马铃薯=1/4)、T5(玉米/秋马铃薯=2/2)、T6(玉米/秋马铃薯=2/3)、T7(玉米/秋马铃薯=2/4)共7个处理,分析比较不同行比间作下马铃薯生长环境、形态特征、产量的变化。结果表明:在各处理中,T2处理较T5处理产量显著增加9.74%,增产效果明显;马铃薯的株高随着玉米/秋马铃薯行比的减小而减小;各处理的土壤含水量的差异不显著;T2处理较T7处理的日均土壤温度显著降低8.9%,日温差显著降低46.7%。综合分析,针对中原二作区特别是鲁西南地区玉米与秋马铃薯等带宽间作模式,1行玉米间作2行秋马铃薯的间作模式更有利于秋马铃薯的生长。
To explore the effects of different row ratios in maize/autumn potato intercropping on the growth of autumn potato in the central double cropping system zone.this experiment set up seven row ratios:T1(maize/potato=1/1),T2(maize/potato=1/2),T3(maize/potato=1/3),T4(maize/potato=1/4),T5(maize/potato=2/2),T6(maize/potato=2/3)and T7(maize/potato=2/4).The morphological characteristics and yield of potato and edaphic condition under different row ratios were analyzed and compared.The results showed that T2 increased the yield compared to other treatments;The plant height of potato decreased with the decrease of the row ratio.There was no significant difference in soil moisture content among the treatments;The daily soil temperature in T2 was reduced 8.9%and the daily temperature reduced 46.7%compared to T7.Based on comprehensive analysis,one row of maize and two rows of autumn potato(maize/potato=1/2)is more implementary with respect to the growth of autumn potato in Shandong province,especially in the southwest part.
