玉米被称为饲料之王,然而玉米单产却一直徘徊在400千克左右,因此,努力搞好夏玉米栽培,对提高粮食产量具有重要的意义。一、选用良种选用优良的玉米杂交种,是获得玉米增产的关键技术措施之一。选用适宜的优良玉米杂交种,在不增加其他投入的条件下,也可获得较好的收成,一般可增产30%左右,若做到良种与良法配套,增产潜力更大。不同的优良品种有不同的特征特性,郑单958株型比较紧凑。要使玉米获得增产,就必须根据当地的实际情况选用良种。一般平原地区选用郑单958、中科4号、浚单20、蠡玉16等。
Corn is called the king of feed, however, corn yield has been hovering around 400 kg, therefore, efforts to improve summer corn cultivation, to improve food production is of great significance. First, the selection of elite varieties of hybrid corn selection, access to corn yield one of the key technical measures. Selection of suitable hybrid corn hybrids, without increasing other inputs under the conditions, but also get better harvest, the general increase of about 30%, if good varieties and good law, increase production potential even greater. Different varieties have different characteristics and characteristics, Zhengdan 958 plant type is more compact. For corn to increase production, it must be selected according to the local conditions. General plains area selection Zhengdan 958, Section 4, Jun Dan 20, Yu-16 and so on.
