我县水稻面积较大,随着复种指数的提高,稻茬麦比例增加,晚茬面积不断扩大,1980年全县霜降后播种的三麦15万亩左右,约占三麦总面积的25%。总结稻茬麦的增产经验,改变晚茬麦低产局面,促使大面积平衡增产,是三麦生产上急待解决的重要问题。晚茬麦低产原因(一)播种季节晚,不利于早发壮苗。我县稻茬麦播种时间一 The area of ​​rice in our county is larger. With the improvement of multiple cropping index, the proportion of rice in wheat increased and the area of ​​stubble continued to expand. In 1980, about 15 million mu of smeltery was planted after the frost reduction in the county, accounting for about 25% . Summarizing the experience of increasing yield of rice stubble wheat, changing late crop low yield wheat situation, and promoting large-scale balanced yield increase, is an urgent need to be solved in Sanmai production. Late crop of wheat low yield reasons (A) late sowing season is not conducive to early seedlings. My county rice stubble planting time one
