通过两年不同灌溉处理对水稻各生育期的灌水量及产量构成因素的影响进行研究。结果表明:控制灌溉每亩用水总量和节水灌溉区每亩用水总量都比常规灌溉节约用水,还降低了成本。第一年参试品种为龙稻21号,第二年参试品种为松粳20号,在控制灌溉和节水灌溉条件下均比常规灌溉增产。 Through two years of different irrigation treatments on the growth of rice during the irrigation amount and yield components of the impact study. The results show that the total amount of water per mu for controlling irrigation and the total amount of water per mu for water-saving irrigation area save water compared with conventional irrigation, and the cost is also reduced. The first year was Longdao 21 and the second was Songjing 20, which increased yield compared with conventional irrigation under controlled irrigation and water-saving irrigation.
