生产实践证明,大面积种植玉米,实行隔行去雄,不影响玉米的正常授精和结实,可提高去雄株的单株玉米产量;当玉米雄穗散粉结束后,剪除其残花(简称剪雄),仍能促进增产。为充分证明此项工作的现实意义,我们于1983年在崇明县港东公社静南大队,第九生产队选择一农户,在其责任

Production practice has proved that planting corn in large areas, the implementation of interlacing to male, does not affect the normal fertilization and fruiting of maize, can improve the yield per plant of single maize; when maize tassel after the end of the powder, cut its residue (referred to as shears male) , Still can promote the increase of production. In order to fully prove the practical significance of this work, we selected a farmer in 1983 at Jingnan Team, Hong Kong East Commune, Chongming County,
