人们发现,如今出售的瓜果,如西红柿(番茄)虽个个红艳欲滴,但口感反不如从前香甜。这是什么原因呢?蔬菜研究人员发现,现在瓜果从培植到开花结果,整个过程中,除了化肥,还要使用植物生长素和农药等多种化学物品。这些东西的使用,虽缩短了瓜果的生长周期,促进了农作物的商品成熟。即外观上的成熟,虽然对人体健康无害,但却把瓜果的自然成熟过程改变了,也就是说瓜果并未达到真正的生理成熟。又如西瓜,看样子熟了,但瓜籽却是白的,口味不如从前,也是这个缘故。所以如今不论瓜果,甚至蔬菜,味道都变得不自然,不香了。 People found that the fruits sold today, such as tomatoes (tomato) although a red Yan dripping, but the taste is not as sweet as ever. What is the reason? Vegetable researchers found that fruits are now cultivated from the flowering to fruiting, the whole process, in addition to fertilizers, but also the use of auxin and pesticides and other chemicals. The use of these things has shortened the growth cycle of fruits and promoted the maturity of crops. That appearance of maturity, although harmless to human health, but the fruits of the natural maturation process changed, that is, fruits and vegetables did not achieve the true physiological maturity. Another example is the watermelon, looks like cooked, but the seeds are white, tastes worse than before, but also for this reason. So now regardless of fruits and vegetables, even vegetables, the taste has become unnatural, not fragrant.
