玉米“一穴多株”种植技术模式是一项有效增加玉米种植密度的技术措施,但在推广该技术的同时,必需同当地农田灌溉条件相结合,才能发挥出应有的效果。在一般旱地和二、三类旱地上不宜大面积推广。本文通过3年来该种植模式的试验、示范,探讨出玉米“一穴多株”在灌溉条件和不同降水年景情况下,该种植模式的增产、增效作用。 Corn “one hole more than one ” planting technology model is an effective measure to increase the density of corn planting techniques, but in promoting the technology at the same time, must be combined with local farmland irrigation conditions in order to play its due effect. In general dry land and two or three types of dry land should not be large-scale promotion. Through the experiment and demonstration of this planting mode in three years, this paper explores the effects of increasing yield and increasing synergism of this planting mode under the condition of irrigation and different precipitation years.
