摘要
通过多点田间对比试验,分析了不同灌溉模式、不同施肥方式对南方地区单季水稻需水特性的影响。研究表明,同一区域不同灌溉模式单季水稻需水量变化基本一致;不同区域受外部水文气象条件的影响,其需水高峰期出现的时间存在差异;施肥方式对单季水稻需水量的影响小于灌溉模式,在合理施肥条件下、增加施肥次数会略增加水稻需水量。
Using field experiment to analysis the effects of different combinations of fertilizations and irrigations on the water requirement of single cropping rice in south China. The results indicate that, in the same region, the rhythms of rice water requirement between different irrigation models are consistent; The fastigium of rice water requirement between different regions are differ; Fertilization modes show fewer influence on rice water requirement than irrigations. Increasing times of fertilization will enhance the water requirement of rice.
