由中国农业科学院作物科学研究所育成的中糯1号是目前国内最优良的鲜食糯玉米品种之一。引入河北省北部地区后,经过多年多点试验、示范和推广,已总结出一套行之有效的优质高产栽培技术。主要技术环节如下:1 隔离种植糯玉米的糯性基因属于胚乳性状的隐性突变体。种植中如果与其他类型玉米品种串粉而产生花粉直感现象,就会影响品质,因此必须隔离种植。隔离的方法有:1.1 空间隔离中糯1号种植田周围300m 内不能同期种植其他类型玉米品种。不具备这种条件时,也可利用山体、村落等进行自然屏障隔离。1.2 时间隔离
Zhong Nuo 1, bred by Institute of Crop Science, Chinese Academy of Agricultural Sciences, is one of the finest fresh waxy corn varieties in China at present. After the introduction of the northern region of Hebei Province, after many years of trial, demonstration and promotion, has concluded a set of effective high-yielding cultivation techniques. The main technical aspects are as follows: 1 Waxy genes isolated from waxy corn are recessive mutants of endosperm traits. Planting and other types of corn varieties in series with the resulting pollen directly feeling the phenomenon will affect the quality, it must be isolated planting. The methods of isolation are as follows: 1.1 Spatial Isolation The other types of maize varieties can not be planted within 300m around the No.1 Nuo-Tian area. Do not have such conditions, you can also use the mountains, villages and other natural barrier isolation. 1.2 time isolation
