人们总以为浸透的种子能加快萌芽,但实际上这样做却弊多利少。通常,种子播下后,就从土壤吸取水分,形成根尖,在种皮上突破一小孔,幼苗遂得以自由伸展、长大。可是,如果种子浸泡过或土壤太湿,种子吸水太快,种皮就会爆裂。氨基酸、蛋白质和糖等内含物会透过这些裂缝渗到土壤周围去。它们滋养了土壤中的致病真菌,并使幼嫩而易受感染的幼苗感病。对于禾谷类和豆类作物来说,这个问题更大,即使不浸种,若将种子播在湿土中或播后 People always think that the seeds soaked can speed up germination, but in fact it does more harm than good. Normally, after the seeds are sowed, water is drawn from the soil to form a root tip, which breaks through a small hole in the seed coat to allow the seedlings to freely stretch and grow. However, if the seeds are soaked or the soil is too wet, the seeds will absorb water too quickly and the seed coat will burst. Amino acids, proteins and sugars penetrate the soil through these cracks. They nourish pathogenic fungi in the soil and sensitize young, vulnerable seedlings. This problem is even greater for cereals and legumes, and even if the seed is not soaked, if the seed is sown in wet soil or after sowing
