番茄空心也叫空洞果,主要表现为果实外观不圆整,表面呈棱角状,表皮厚薄不匀。果实内胎座组织发育不充实,果实与胎座组织分离,形成空腔。果实水分少,重量轻,品质差。一、形成原因一是大棚内浇灌水的温度过低,是造成“空心果”的直接起因,在低温情况下,番茄根部受冷收缩,根须活力降低,吸水性差,如此时植株幼果正处于膨大期,在短期缺少水分供应的情况下,则易出现局部的果中少肉现象。二是留果过多,每穗留果量不宜太多,否则 Tomato hollow also called hollow fruit, mainly for the appearance of fruit is not round, the surface is angular, uneven skin thickness.
