北京市正在农村地区推进籽种更新换代。由于种子质量的千差万别,造成地里庄稼参差不齐、产量高低不均的现象,将逐渐在京郊销声匿迹。日前,房山区已率先启动了小麦籽种更新工程,计划用3年时间更新全区1万公顷小麦的籽种,预计可由此增产10%。 Beijing is promoting seed replacement in rural areas. As the seeds of different quality, resulting in uneven cropping, uneven output levels will gradually disappear in the suburbs of Beijing. Recently, Fangshan District has taken the lead in starting the wheat seed renewal project, and plans to update the seed of 10,000 hectares of wheat in the whole region in three years, and is expected to increase the yield by 10%.
