| 中文摘要: |
| 在滴灌条件下,分别设置295 mm、345 mm、395 mm4、45 mm这4个不同的灌水处理;同时设置1个沟灌处理为对照,对不同灌水量处理的大豆田间土壤水分动态及大豆田间耗水规律进行分析研究,初步确立在石河子地区,滴灌大豆适宜的灌溉制度参数为:灌溉定额为395~445 mm,灌水定额为35~45 mm,苗期和成熟期取下限,灌水周期为7 d;花荚期和鼓粒期取上限,灌水周期5 d,整个生育期灌水13次。 |
| 英文摘要: |
| Under drip irrigation, four irrigation treatments, such as 295 mm, 345 mm, 395 mm and 445 mm were deisigned, and a furrow irrigation was also established as the control.According to the arrangement of irrigation and water requirement of soybean, the schedule of drip irrigation was: 35 mm for every 7 days in seedling stage, 45 mm for every 5 days in bloom-pod setting stage and pod setting-seed filling stage, 35 mm for every six days in seed filling-maturity stage, and with water consumption between 395 mm and 445 mm during the whole stage. |
