水稻浅水灌溉.即以浅灌为主。根据水稻不同生育期对水分的要求.采取深浅结合,适当烤田等措施调节温度和养分.促进根系生长、稻秆粗壮,防止倒伏,控制生育,以及形成大穗.增加千粒重等,达到增产的目的。如营口水源灌区,浅水灌溉,生育期的平均水温为24.2℃,比深水灌溉提高1.2度;平均地温23.5℃.比深水灌溉提高0.7度.既有利于水稻的生长发育,又可节约用水四分之～至二分之一。降低水电成本。根据一些地区的经验.现将浅水灌溉的做法介绍如下:
Shallow irrigation of rice, which is mainly shallow irrigation. According to the different growth stages of rice water requirements .Adopting the combination of shades and depths, appropriate baking fields and other measures to adjust the temperature and nutrients to promote root growth, stout thick, to prevent lodging, control fertility, and the formation of big ears. Increasing 1000-grain weight, to increase production purpose. For example, Yingkou Irrigation District and shallow water irrigation have an average water temperature of 24.2 ℃ during the growth period, an increase of 1.2 degrees compared with that of the deep-water irrigation, an average ground temperature of 23.5 ℃, 0.7 degrees higher than that of the deep-water irrigation, which is beneficial to the growth and development of rice, ~ ~ One half. Reduce water and electricity costs. Based on the experience of some regions, the practice of shallow water irrigation is as follows:
