甜玉米是一种营养价值很高,深受人们喜爱的食品,近年来我省各地已有较多种植。为了提高其食用品质和经济效益,必须根据甜玉米的特性,采用相应的栽培管理方法。主要需注意以下几点: 一、注意与普通玉米隔离种植目前我国育成的甜玉米杂交种有两类,一类是由隐性基因甜—1(SU—1)控制的普通甜玉米,另一类是由隐性基因凹陷—2(Sh2)控制的超甜玉米。这两类甜玉米若与普通玉米串粉,表现为普通玉米的胚乳特性,鲜果穗失去甜性。为防止其串粉,要有300米左右酶隔离距离。也可根据不同品种散粉、吐丝的时期,利用错开播种期的方法进行时间隔离。
Sweet corn is a high nutritional value, loved by the people of food, throughout the province in recent years have been more planted. In order to improve its edible quality and economic benefits, corresponding cultivation management methods must be adopted according to the characteristics of sweet corn. The main points to note are as follows: First, pay attention to isolation and planting of common maize At present, there are two types of sweet maize hybrids bred in China, one is the common sweet corn controlled by the recessive gene sweet -1 (SU-1) Classes are super sweet corn controlled by recessive gene recession -2 (Sh2). If these two types of sweet corn with ordinary corn skewer powder, the performance of the endosperm characteristics of ordinary corn, fresh ears lose sweetness. In order to prevent its string meal, there should be about 300 meters enzyme isolation distance. Can also be based on different varieties of loose powder, spinning period, the use of staggered sowing method of time isolation.
