摘　　要：为了探讨稻麦两熟制地区,小麦不能适期播种的情况下,晚播尽可能提高产量的对策,特进行小麦机械条播、机械摆播、人工撒播3种方式不同播期试验,研究东海地区小麦播期推迟情况下,不同播种方式对产量的影响。结果表明:机械条播、机械摆播增产优势不明显,3种方式播种越早产量越高,在水稻收获后应尽可能抢墒播种,并通过适当增加播量(基本苗)来提高群体数量。同时,在播期推迟的情况下,适当减少基肥的用量,增加中后期肥料用量,减少无效分蘖的发生,促进壮秆大穗,以利于晚播麦高产。In order to study the measures that could increase the yield of wheat in rice-wheat growing system area when the sowing time was delayed,the test was done with mechanical drilling,mechanical pendulum sowing and artificial sowing in different sowing time.The results showed that the advantages of mechanical drilling and mechanical pendulum sowing were not obvious.The higher yield earlier sowing time ,so that we should sow wheat grabbing moisture after harvesting the rice.Meanwhile ,we could appropriately increase seeding rate （planting density ）to increase the number of groups.When the sowing time was delayed ,we should reduce the amount of basal fertilizer and increase the amount of fertilizer in the late ,so as to reduce the ineffective tillers and get high yield of late sowing wheat.
