要想知道让果实膨果上色好,就得从现在这个时段,影响果实膨果上色的原因说起。那冬季影响果实膨果上色的因素有哪些呢?

1、土壤根系问题:

很多土壤,由于酸碱化严重,加上肥料残留过多,导致营养富集严重,有的有害病菌也很多,导致根系很差,导致养分供应慢,不能满足果实膨果上色的营养需求。

2、果实上色期叶片过少:

这个其实也跟营养有关系,由于在果实转色期叶片大量脱落,无法制造足够的营养,果实想膨大转色效果就差。

3、进入冬季由于温度太低,前期营养积累的又不是很足,加上一般果实膨果转色增甜的理想温度达不到,一般为:26-30度果实膨果转色更好,因此需要我们想法提高植物的光合作用及温度。

4、挂果量太大或植株太旺:

这个很容易发生,需要我们平时注意一下,并注意氮肥与浇水量的控制。

其实总结一下,影响果实膨果上色的因素除了病虫害及天气原因外,主要就是土壤根系及营养供应的问题,因此针对上面四点,总结了以下几个措施:

1、如果根系土壤不好,在果实膨果转色期,建议冲施养护改良土壤的自带营养生物菌冲施肥,为土壤补充有机质的同时,为根系补充所需的氨基酸、蛋白质,维生素,并同时补充可以活化分解营养的有益生物菌群,这样的组合可以有效提高土壤活力并消灭有害病菌,为根系生长补充所需营养,对于膨果转色期效果比较好。

2、除了地面施肥外,建议结合叶面喷施果实膨果转色所需的磷、钾、硼、钙等营养元素,可以叶面喷施高磷钾钾的液体肥,这样补磷补钾效果更好,对于硼钙元素肥可以补充可以钙硼同补的硼钙叶面肥或钙硼合剂。

3、由于现在光合作用弱,因此我们可以使用提高植物自身光合速率的叶面肥,常见的有有机钛硼钙叶面肥,有机钛可以提高植物本身的光合作用,并同时补充膨果转色需要的硼钙元素,综合效果还是不错的。

我觉得其实如果要自然来说的话,最好还是让它多晒太阳,这个样子它的果实就感觉特别饱满,而且效果也特别好。

回答3:

一、果实着色原理
叶绿素、类胡萝卜素、和花青素是决定果实颜色的三大类植物色素。
这三种物质显示的颜色分别是:绿色、黄色、红色,在正常成熟的果实中,叶绿素显示的颜色(绿色)褪去,或与类胡萝卜素显示的颜色(黄色)构成果面的底色,花青素显示的颜色(红色)构成表色。
因为这三种物质在果皮内生成的比例不同,而形成各种色调的果子。

可以给果实喷硼砂,兑上白糖,效果很好的。希望可以帮到您,感谢您的采纳!

秋季是果实膨果着色的关键期,用磷酸二氢钾+硼砂+氨基酸钙喷施效果好
