| 摘 要： | 根据田间试验资料,对冬小麦畦灌与喷灌条件下的耗水量与灌溉制度进行了研究分析,并取得初步成果:冬小麦生育期内深层土壤水的利用量随着灌溉水量的增加而减少;为了节省灌溉用水量,充分利用土壤水,灌水次数不宜过多;在灌水量相近的情况下,喷灌与畦灌相比可获得更高的产量,其水分生产率较高;喷灌可以实现小水勤灌,但在冬小麦生长期灌水次数不宜过多。 |

| Abstract: | Water consumption and irrigation system are studied on winter wheat under the condition of spray and boundary irrigation, the primary result is obtained based on field experiment: The amount of soil water utilization in deep layer soil is decreased within procreating period of winter wheat along with the amount of irrigating water increasing; the time of irrigation might not be suitable overabundance in order to full use of soil water for saving irrigation water; The yield of crop irrigated by spray irrigation is higher than the one irrigated by boundary irrigation, and its water productivity of wheat is higher. A small amount of irrigation might be realized, but the time of irrigation might not be suitable overabundance during the growing period of winter wheat. |
