目前麦田铺草通常在播后苗前进行,这容易形成“黄苗”、“豆芽苗”,对麦子立苗、分蘖、成穗,甚至当季产量都有一定影响.近三年,我们结合本地实际,在麦田进行了“苗后行间铺草”试验研究,较好克服了麦田常规铺草的不利影响.材料与方法试验田土壤为夹沙土,肥力水平中等偏下,0~20cm土层有机质含量为1.34%,全氮0.087%,速效磷3mg/kg,速效钾76mm/kg,土壤容重1.29g/cm~3
At present, the wheat field grass is usually carried out before sowing after sowing, which is easy to form “yellow sprouts” and “sprouts sprouts” and has certain influence on the wheat seedling, tillering, spike formation and even seasonal yield. In the past three years, According to the actual situation in our country, the experiment of “laying grass between seedlings and rows” was carried out in wheat field to overcome the unfavorable effects of conventional grass planting in wheat field.Materials and Methods The soil in the experimental field was sand-clayey soil with medium-low fertility, 0-20 cm soil layer Organic matter content 1.34%, total nitrogen 0.087%, available phosphorus 3mg / kg, available potassium 76mm / kg, soil bulk density 1.29g / cm ~ 3
