佳木斯市位于三江平原下游,虽然水资源比较丰富,但因年、季降雨量变率很大,春季降雨仅占年降水量的15％,因此,种植水稻常发生春旱渴水现象。过去农民种稻习惯于固定水层深水串灌,不仅浪费水量,加剧干旱,而且影响了稻谷产量和灌溉面积扩大。近几年来,我们为了研究水稻节水高产灌溉制度,在部分重点灌区采用了“浅晒浅”,“浅晒深浅”等变动水层的灌溉制度试验,在
Jiamusi City, located in the lower reaches of the Sanjiang Plain, although rich in water resources, but because of the large annual and seasonal rainfall variability, spring rainfall accounted for only 15% of annual precipitation, therefore, rice often spring thirst and thirst phenomenon. In the past, peasants who used to grow rice were accustomed to fixed-layer deep-water irrigation, which not only wastes water and aggravates the drought, but also affects the output and area of irrigated rice. In recent years, in order to study the water-saving and high-yielding irrigation system for rice, the irrigation system experiments of shallow water layer, shallow water layer and shallow water layer were adopted in some key irrigation areas.
