摘要
不同配方专用肥在河西灌漠土上对春小麦的肥效试验研究结果表明,配方A、配方C较对照分别增产24.8%和24.0%,其中配方A对小麦全生育期营养需要均能满足而能获高产,但对资源分配的协调能力较差;配方C较好地协调了小麦营养生长与生殖生长的养分供应矛盾,使小麦高产抗病,抑制杂草生长,为河西地区首选的小麦专用肥。
Efficiency test of different special fertilizer formula for wheat were conducted in irrigated desert soil in Hexi corridor. The result showed that formula A and C can increase rape yield by 24. 8% and 24. 0% compared with contrast respectively. Formula A can meet the nutrient need during the whole growth period of wheat for high yield, but it can not coordinate resource distribution well. Formula C can harmonize the contradiction of nutrient supply for vegetation growth and reproductive growth well, increase wheat yield and control weed growth. So formula C is the first special fertilizer for wheat in Hexi region.
