补充资料：播种
| 播种 sowing 将播种材料按一定数量和方式，适时播入一定深度土层中的作业。播种适当与否直接影响作物的生长发育和产量。 适时播种是使作物从种子发芽、出苗到成熟的各个生育期获得有利气候条件、全苗壮苗、植株正常生长、适时成熟的重要措施。不同作物的播种适期主要决定于品种特性、温度、水分、栽培制度、土质和地势。播入单位面积土地的种子重量， 以千克/公顷为单位。适宜的播种量是合理密植的前提。一般按每公顷密度（株数）、种子千粒重、发芽率和田间出苗率等指标计算。播种深度关系到种子的发芽、出苗的好坏和幼苗生长。应根据作物、土壤、气候条件确定适宜深度。播种方式应根据作物种类，生育特性，耕作制度、种植密度和播种机具等因素确定。一般分为撒播、条播、点播3类。 |
