搞好品种的适区种植,是关系到农业生产是否持续增产的大问题,也是各级政府、农业部门十分关心的问题。近几年来,由于我省温度较高,一些地方选用的品种越来越晚,这样就会给农业生产带来潜在危险。晚熟品种一般高产,但危险性大,早熟品种虽然比较安全,但产量低,这是一个矛盾。 It is a major issue that concerns whether the agricultural production will continue to increase its production, and it is also a matter of great concern to governments at all levels and to the agricultural sector. In recent years, due to the high temperature in our province, the varieties used in some places become more and more late, which will bring potential danger to agricultural production. Late-maturing varieties generally high yield, but the danger is high, although the precocious varieties are relatively safe, but the yield is low, this is a contradiction.
