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。
Aiming at the problem of more than 80% of summer sowing millet planted in dry land and low and unsteady yield, the effects of furrow sowing on the growth and yield of millet root were studied by random block design. The results showed that: Furrow sowing had a significant role in promoting the growth and yield of millet roots. The total root length, total surface area, total volume, root tip number and root diameter of furrow sowing on the micro-ridge film were significantly higher than those of the control 14.63%, 21.59%, 31.59%, 11.44%, 12.39%. The yield increased by 44.59%. The yield had significant positive correlation with root length, total surface area, total volume, root number, root dry weight and root diameter.
