摘要
据调查,丹江口市种植和上市销售的糯玉米普遍存在大穗比例不高(穗长10～20 cm占60%～70%),小穗和劣质穗比例大(穗长10 cm以下、虫蛀、稀子穗占30%～40%),单季鲜穗产量达不到每公顷10 t,产值每公顷1.5万元左右。为了提高全市糯玉米科学种植水平,提高群体大穗比例,提高公顷产值,根据美糯2号、赣新花糯1号优质高产、高效栽培示范,提出了双季糯玉米鲜穗产量每公顷超30 t、产值每公顷超6万元的主要技术措施。
In order to improve the cultivation level of waxy corn in our city, incease the proportion of big ear in population and the output per hectare, some technical measure was studied in this paper to enhance the output of double cropping fresh waxy corn up to more than 30t·hm^-2 and increase its value up to more than 60 000 Yuan·hm^-2.
