    ③播种方法 播种方法以条播较多,有利于中耕除草。北方播种后镇压,是保墒保苗的重要环节;南方因雨水较多,播后覆土即可。生长越整齐,产量越高。影响生长整齐度***重要的是垄内稻苗分布均匀程度,播种时要确保落粒均匀。覆土的厚度对出苗影响也很大,直接影响早稻的发芽率和出苗整齐度。如覆土过浅,遇到天旱,地表水分蒸发快,难以满足种子所需要的水分,不能发芽。如遇先雨后旱,已发芽也会引起胚芽过度生长,消耗种子养分,芽鞘出土能力减弱,甚至叶片在土内即展开,形成出苗缓慢,出苗率低,根系不发达。覆土厚度应根据土壤质地、季节和水分而定。一般壤土以3~4厘米为宜,沙土及土壤干旱时覆土可较深,粘土及土壤水分多时可较浅。南方春播覆土可浅些,3厘米左右即可,夏播宜稍深。
