為什麼一些植物會生病甚至死亡（why some plants become sickly or die）
there are a variety of factors to be considered when explaining plants become sickly or die.
first of all, dryness in the soil causes the leaves to loose freshness, or wilt, and may result in death of the plant.
on the other hand, too much water may result in the leaves loosing their strength and drooping, or in their becoming yellow, and occasionally in the rotting of the leaves and stems.
while sunshine is necessary for plants, if it is too strong,the soil may be baked and the roots killed. however, if there is no light, the leaves will become pale and the stems thin, and if not corrected, the consequence will be the death of the plant.
為什麼有些植物會生病會死亡
為什麼有些植物會生病或死亡這個問題，有很多因素值得考慮。
首先，土壤乾燥致使葉子失去水份或枯萎，最終有可能導致植物的死亡。 ()
相反，太多的水份有可能使葉子失去力量，向下垂落，或變黃，有時葉子或莖部變腐壞死。
雖然陽光對植物是非常必要的，但如果陽光過強，土壤會被烤乾，根被燒死。然而，如果沒有陽光，葉子就會長得蒼白無力，莖部會變得細嫩單薄。若得不到及時的糾正，結果只有死路一條。
