灌溉农业中,小麦产量常受灌水早晚、灌水次数与灌水期距的影响。要使小麦高产稳产,首先要促壮苗;其次是拔节以后促壮株;第三是保花、增粒、促穗齐;最后是促灌浆,使籽粒饱满,正常落黄。要达到这些目的,用水促控,效果最为明显。为了探索 Irrigated agriculture, wheat yield often affected by irrigation sooner or later, the number of irrigation and irrigation interval effect. To make wheat high and stable yield, we must first promote strong seedlings; followed by promoting strong strains after jointing; the third is to protect the flower, grain, and promote ear Qi; Finally, promote grouting, so full of grains, the normal yellow. To achieve these goals, water control, the effect is most obvious. To explore
