晚播麦田的特点是播种晚、施肥少、分蘖少、亩茎数少,这类麦田成全县小麦再上新台阶的拉腿田。因此早春巧管晚播麦,促进早春分蘖成穗,是夺取晚播麦丰产的关键。 一、中耕锄划、增温保墒。若入冬后总降水量大,土壤墒足,早春要中耕锄划,增温保墒,破除板结,促进土壤微生物和小麦分蘖节活动,以利于晚播麦早返青,早牛长,促使早春多分蘖,提高分蘖成穗率。 二、清棵:晚播麦一般播种较深,个体发育细弱,在早春土壤化冻后用竹耙把麦行里的土往行间扒一些,使分蘖节盖土厚度变薄,利于提高分蘖节周围的 Late-sowing wheat field is characterized by late sowing, fertilization less, less tiller, the number of acres of stalks less, such wheat fields into county wheat to a new level of legged fields. Therefore, early spring coincidentally late sowing wheat, to promote early tillering panicle, is the key to seize the late sowing wheat yield. First, cultivating hoe draw, warming moisture. If the winter after the total rainfall, soil moisture footprinting, hoeing in the early spring to cultivate, warming soil moisture, breaking the knots and promote soil microbes and wheat tillering Festival activities in order to facilitate the early sowing wheat early greening, early cattle long, prompting more spring and more Tiller, increase tillering rate. Second, the clear trees: Late sowing generally sowing deeper, individual development is weak, after the soil thaw in early spring bamboo rake to the line between the soil grilled some, so that tiller Festival cover thinner, which will help improve the tillering Festival surrounding
