2006—2008年,在辽西地区开展了促进红富士苹果果实着色的配套栽培技术研究,主要采取了控冠改形、土肥水管理、果实套袋、摘叶转果、地面铺反光膜等一系列技术措施。研究表明,示范园的果实花青苷含量比对照高出1.64～2.70倍,果实着色面积比对照高出10%以上,全红果率比对照高出5倍以上。说明这些生产技术措施对于促进果实着色都十分有效,而且果实较对照色泽更鲜艳浓红,果实综合品质也有很大提高。
From 2006 to 2008, research on the cultivation techniques for promoting the fruit coloration of Red Fuji apple was carried out in western Liaoning. A series of experiments were carried out to control the coloring of red Fuji apple fruits, such as crown control, fertilizer management, fruit bagging, leaf pick-up, Technical measures The results showed that the fruit anthocyanin content in the demonstration garden was 1.64-2.70 times higher than that of the control, the fruit coloring area was over 10% higher than the control, and the whole red fruit rate was more than 5 times higher than that of the control. This shows that these production techniques and measures are very effective for promoting fruit coloring, and the fruit is brighter than the control color, and the comprehensive quality of the fruit is also greatly improved.
