摘要： 针对夏播谷子80%以上种植于旱地、产量低而不稳的问题，采用随机区组设计，研究了微垄膜侧沟播对谷子根系生长发育和产量的影响，结果表明：微垄膜侧沟播对谷子根系的生长发育和产量具有显著的促进作用，微垄膜侧沟播的总根长、总表面积、总体积、根尖数、根直径均显著高于对照，分别较对照增加了14.63%、21.59%、31.59%、11.44%、12.39%。产量增加44.59%，产量与根长、总表面积、总体积、根尖数、根干物重、根直径具有显著的正相关关系，发达的根系是微垄膜侧沟播技术增产的根源。

Abstract: 80% of summer sowing millet is planted in dry land and has low and unstable yield. To solve this problem, the effect of furrow sowing beside plastic film covering micro-ridges on root growth and development and yield of millet are studied by randomized block design. The results showed that this new cultivation technique significantly promoted root growth and development and yield of millet, the total root length, total surface area, total volume, number of root tip and root diameter increased by 14.63%, 21.59%, 31.59%, 11.44% and 12.39%, respectively, compared with that of CK. The yield increased by 44.59%, the yield had significantly positive correlation with total root length, total surface area, total volume, number of root tip, root dry matter and root diameter, developed root system was the reason for yield increase under the cultivation technique of furrow sowing beside plastic film covering micro-ridges.
