发展水稻是改造三江平原低产田提高产量的有效途径 ,但受地表水资源限制 ,必须合理地开发利用地下水资源。但地下水出井温度只有 4～ 6℃ ,这对喜湿喜温的水稻是一个致命的弱点 ,怎样才能有效地提高井水温度来满足水稻生产发育 ,是需要解决的一个现实问题 ,文章论述了通过灌溉渠道升温、折冲式晒水池升温 ,普通晒水池调温三种工程措施的试验 ,认定普通晒水池效果最好 ,不仅可拦截水旱田径流 ,还可养鱼养鸭养鹅 ,肥水灌田
Developing rice is an effective way to improve the yield of low-yielding fields in the Sanjiang Plain. However, limited by surface water resources, groundwater resources must be rationally exploited. However, the outlet temperature of groundwater is only 4 ~ 6 ℃, which is a fatal weakness to hi-humidity rice. How to effectively raise the temperature of well water to meet the needs of rice production is a realistic problem to be solved. Irrigation channels warming, folding sunbather heats up, ordinary sunbathing thermostat test of three engineering measures, that the best ordinary sunbathing, not only to intercept runoff and water runoff, but also fish duck goose, fertilizer and irrigation
