摘　　要：为了研究在阴雨天气影响下,稻茬晚播小麦不同播种方式对小麦生长及产量的影响。以罗麦10号为研究对象,研究在稻茬小麦晚播情况下不同播种方式对小麦生长及产量的影响,结果表明:零共生小麦在播种期提前19 d情况下,全生育期增加17~19 d,成熟期提前1~2 d,有效穗数增加2.1%~4.6%,穗实粒数增加1.8~7.2粒,千粒重增加1.4~1.9 g,产量增加7.2~27.1 kg/667 m 2,同时对稻茬晚播小麦的茎秆性状也有显著的影响。在水稻迟收又遇到连阴雨天气的情况下,选择零共生套播种方式可以使小麦生育期和产量得到保障。In order to study the effects of different sowing methods on growth and yield of wheat under the influence of rainy weather.Luomai 10 was adopted as the material to study the effects of different sowing methods on wheat growth and yield under the condition of late sowing of rice stubble wheat.The results showed that the whole growth period of zero symbiotic wheat was increased 17~19 days when the sowing time was 19 days ahead.The maturity period was 1~2 days ahead.The number of effective ears increased 2.1%~4.6%.The number of grains per ear increased 1.8~7.2 grains.The weight of 1000 grains increased 1.4~1.9 g,and the yield increased 7.2~27.1 kg/667 m 2.At the same time,it also had a significant impact on the stem characters of late sowing wheat.In the case of late rice harvest and continuous rainy weather,the zero symbiosis sowing mode can ensure the growth period and yield of wheat.
