小麦“叶龄指标促控法”,是以小麦主茎上出现的叶片数作为指标,采取促控措施的一种科学管理方法。由于小麦主茎上的每一片叶,都与植株上的某一器官(如根、分蘖、节间、叶鞘和穗)的生长发育密切相关,所以按叶龄采取促控措施,就可以有预见性地控制小麦的各个器官,使其向人们所预期的方向发展,从而达到高产稳产。此法在北京郊区推广以来,已获得较显著的增产效果。由于它是以小麦生长发育的共性规律为基础,所以具有普遍意义,可以在全国各地辩证应用。 Wheat “leaf age index control method”, is based on the number of leaves on the main stem of wheat as an indicator, to take measures to promote a scientific management approach. Since every leaf on the main stem of wheat is closely related to the growth and development of certain organs (such as roots, tillers, internodes, leaf sheaths and spikes) on the plant, it is foreseeable Sexually control the organs of wheat to the direction expected by people to achieve high and stable yield. This law has been in the suburbs of Beijing since the promotion, has been more significant yield increase. Because it is based on the common law of wheat growth and development, it has universal significance and can be dialectically applied across the country.
