                圆茄果实花萼处皴皮是什么原因?

                菜农咨询:圆茄果实花萼处皴皮,卖相不好,十天没有打药了,也没有蓟马或螨虫,请问这是什么原因,如何解决?

                圆茄果实花萼处皴皮是什么原因?

                解答:从描述分析,这个现象与虫害和药害无关,也与缺素症和侵染性病害无关,应是点花药出了问题。点花药浓度过大时,就会抑制幼果生长,幼果紧缩发硬和开裂。如果点花药抹花抹的面积大,太重,甚至点花药滴到花萼处,就会形成皴皮。高温天气点花药浓度也要降低浓度,每斤点花药加50毫升清水,加7-8滴赤霉素或碧护。在果实膨大期,适当喷施苏莱特或几丁碳酶或芸苔素加中微量元素叶面肥。(文章来源:北方蔬菜报)
