传统的玉米播种一般不用施肥,只是在大喇叭口期一次性进行追肥,这样做的缺点是玉米苗期养分供应不足,造成苗弱、苗小,不利于创高产,到追肥期时还要进行追肥浇水,不仅劳动强度大,而且费力费时。为使玉米苗期长势壮,提高产量,降低劳动强度,通过近几年的实验和示范推广以及大田种植,总结出了一套夏玉米一次性播种施肥的好方法,其具体做法如下:首先要选用优良玉米品种和适应玉米生长的优质化肥,玉米品种一般采用郑单958、掖单20、京玉7号、蠡玉16等品种,化肥采用含氮、磷、钾的专用肥,亩用量50—60斤,选用现在新
Traditional corn sowing generally do not have to fertilize, but only in the big bell mouth one-time top-dressing, the disadvantage of doing so is insufficient supply of corn seedling nutrients, resulting in weak seedlings, is not conducive to a high yield, to the top-dressing period Topdress watering, not only labor-intensive, but also time-consuming effort. In order to make maize seedling grow strong, increase yield and reduce labor intensity, through a series of experiments and demonstrations in recent years and field planting, summed up a set of summer maize one-time good method of sowing fertilizer, the specific practices are as follows: Selection of high quality corn and corn varieties to adapt to the growth of high-quality chemical fertilizers, corn varieties commonly used Zhengdan 958, Yedan 20, Jing Yu 7, Yu 16 and other varieties of fertilizers using nitrogen, phosphorus and potassium fertilizer, mu 50 -60 pounds, choose now new
