采用随机区组设计,研究了渗水地膜穴播对谷子根系生长发育和产量的影响,结果表明:渗水地膜穴播对谷子根系的生长发育和产量具有显著的促进作用,谷子的总根长、总表面积、总体积、根尖数分别较对照增加了51.30%、47.89%、48.39%、41.63%。产量增加48.57%,产量与根长、总表面积、总体积、根尖数、根干物重具有显著的正相关关系,发达的根系是渗水地膜穴播增产的根源。 Randomized block design was used to study the effect of water-seeded film-mulching on the growth and yield of millet roots. The results showed that water-permeable film-mulching had significant effects on the growth and yield of millet roots. The total root length, total surface area, The total volume and root tip number increased by 51.30%, 47.89%, 48.39% and 41.63% respectively compared with the control. The yield was increased by 48.57%. There was a significant positive correlation between yield and root length, total surface area, total volume, root tip number and root dry matter weight. Developed root system was the root cause of water-hole mulching.
