摘要
为探究在盐碱地中种植水稻所需要的脱硫渣的最适施用量,采用拉丁方设计,研究了水稻不同生长时期的各项水分生理指标以及在不同脱硫渣施用量条件下的变化情况。结果表明：脱硫渣的施用对盐碱地水稻的根系活力、叶片含水量、水分利用效率等指标均有一定的影响,而且能显著提高水稻的水分利用效率;施用效果并不与脱硫渣施用量呈正相关,脱硫渣施用量过大反而会造成水稻根系活力下降,水分利用效率降低,当脱硫渣施用量在22.50～33.75t·hm^-2处理下水稻生长较好,水稻的各项水分生理指标有较大提高。
In order to explore the optimal quantity of desulphurized waste of planting rice on saline-alkali land,through the paddy field experiment,used the Latin square design,the effect of different quantity of desulphurized waste on water use efficiency and its change in different growth stages on saline-alkali land were studied.The results showed that the desulphurized waste on saline-alkali land had certain influence on rice root system vigor,the leaf water content and the water use efficiency,but the quantity must be appropriate.The oversized quantity of desulphurized waste could create the rice root system vigor to drop,the water use efficiency reduces.When optimal quantity of desulphurized waste was 22.5～33.75t·hm^-2,the water use efficiency was the highest.
