油菜生育期长,田间管理的好坏,对于产量高低具有决定性的影响。因此,应坚持推广“种下就管,一管到底”和“抓早、抓紧、抓好”的经验,切实把田间管理工作搞好。油菜的生长发育过程是有规律有阶段的,每一阶段又有它不同的生长发育特点和对外界条件的要求。为此,提出田间管理要分段分期进行。油菜的整个生育期可分为三个阶段,即苗期、现蕾抽苔期、开花结果期。要油菜高产,必须在不同阶段实现不同的要求,而上一阶段又为下一阶段作准备、打基础,必须环环扣紧,一管到底。
Long rapeseed growth period, field management is good or bad, for the yield level has a decisive impact. Therefore, we should persistently promote the experience of “planting under one tube, one tube in the end” and “catching up early, paying close attention to and doing a good job” so as to effectively improve field management. Rape growth and development process is a regular stage, each stage has its different growth and development characteristics and requirements of the external conditions. To this end, proposed field management should be phased staged. The whole growth period of rape can be divided into three stages, namely seedling stage, budding bolting stage, flowering period. To rapeseed production, must be achieved in different stages of different requirements, and the previous stage and prepare for the next stage, laying the foundation, we must ring-fastening, one tube in the end.
