| 摘 要： | 对土质、肥力、面积相同的两块水田地分白天、晚间两个时间进行地下水灌溉试验。结果表明,白天灌地下水对水稻的生长发育和产量有较大影响,其中分蘖始期延迟5d、有效分蘖期延迟6d,最高分蘖期延迟6d,抽穗期延迟4d,成熟期延迟4d,产量降低5.1%。

Effects of Different Irrigation Time of Groundwater on Growth and Yield of Rice |
| |
| Abstract: | Effects of different irrigation time of groundwater on growth and yield of rice were analyzed in the paper. The results indicated that effects were obvious. Compared with irrigation at 5:00 PM, the initial tiller stage of rice irrigated at 8:00 AM was delayed by five days, the effective tiller stage was delayed by six days, the maximum tiller number stage was delayed by six days, the heading stage was delayed by four days, the maturation was delayed by four days, and the yield was decreased by 5.3%. |
