在当前的种植业中,油菜是一个经济效益比较高的大众作物。社会效益和生态效益也较为理想,所以其种植面积是一个持续发展的势头。产量不断提高,这和选用一个适应现有耕作制度,具有稳产高产性能的良种是密切相关的。随着油菜种植面积的不断扩大,复种指数的相对稳定,油菜后茬由以往的后季稻秧田改为很大一部分面积移栽早稻和其它经济作物。这就需要扩大种植中早熟品种,使熟期相应提
In the current crop industry, rape is a popular crop with high economic returns. Social and ecological benefits are also ideal, so its planting area is a continuous momentum of development. The continuous improvement of production is closely related to the selection of a good seedling that has been adapted to the existing farming system and has a stable yield and high yield. With the continuous expansion of rapeseed planting area and the relative stability of multiple cropping index, the rapeseed crop was changed from the former post-season rice seedling field to a large part of the transplanted early rice and other cash crops. This requires the expansion of early maturing varieties, so that the corresponding maturity
