本文探讨了利用天津东南地区浅层咸水和深层高钠碱性淡水配制成的微咸水灌溉农田对冬小麦产量及籽粒品质的影响,以期解决当地农业用水严重不足的问题。盆栽试验表明,用微咸水灌溉的冬小麦与用深层高钠碱性淡水灌溉的冬小麦相比,前者不仅产量高,而且籽粒品质也有所改善。由于微咸水取咸水和高钠碱性淡水之长,而避它们之短,所以,采用微咸水灌溉农田,可能是解决天津东南地区农业用水不足的有效措施之一。
This paper discussed the effects of using brackish water irrigated farmland on the yield and grain quality of winter wheat by using the shallow saltwater in the southeast of Tianjin and deep-seated high-sodium alkaline freshwater to solve the serious shortage of local agricultural water. Pot experiments showed that compared with winter wheat irrigated with deep, high sodium and alkaline fresh water, the former was not only high in yield but also improved in grain quality. Because brackish water takes the length of saltwater water and high sodium and alkaline freshwater and avoids their shortness, using brackish water to irrigate farmland may be one of the effective measures to solve the shortage of agricultural water in southeast area of Tianjin.
