我县麦田历年均出现弱苗,影响小麦产量,只有促弱扶壮,才能夺取平衡增产。现就我县小麦弱苗情况及管理措施分述于后: (1)晚播弱苗,一般是10月25日以后播种,年前主茎叶龄2—3片,个别的达到4片,次生根极少或没有,叶片瘦长,但叶色正常,主要是积温不够所造成。管理措施应以中耕提温为主,促进麦苗生长,也可适当追些速效氮肥,以利冬肥春用。返青后,主茎叶龄3—4片,单株分蘖0—1个,次生根约1.5条,生长缓慢。对于地力好,墒情足,冬 Weak wheat over the years appeared in our county weak seedlings, affecting wheat production, only to weaken the strong, in order to seize the balance of production. Now on the county weak wheat seedlings situation and management measures are described later: (1) late sowing weak seedlings, usually October 25 after sowing, 2-3 years ago the main stem leaf age, individual to 4, Secondary root little or no, elongated leaves, but the color leaves normal, mainly caused by insufficient accumulated temperature. Management measures should be dominated by cultivating temperature to promote the growth of wheat seedlings may also be appropriate to catch up with some quick-acting nitrogen fertilizer to facilitate winter fertilizer use. After returning to green, the main stems 3-4 leaves, tillers 0-1 per plant, about 1.5 secondary roots, slow growth. Good for the land, moisture enough foot, winter
