为什么月季大苗缓苗不能晒太阳？

月季是一种美丽的花卉，许多人喜爱将其种植在花园中。然而，对于月季大苗来说，它们在生长初期需要特别的照顾和环境。其中一个重要的注意事项是避免过度暴露在阳光下。

月季大苗作为刚刚移植到新的环境中的植物，它们的根系通常还不够健壮。如果暴露在强烈的阳光下，光照和高温会导致大量的水分蒸发。这会使得根系无法吸收足够的水分和养分，从而导致幼苗枯萎和死亡。

此外，强烈的阳光照射还会引起月季叶片的灼伤。月季叶片嫩绿且柔嫩，容易被日晒损伤。受损的叶片会变黄、枯萎甚至褪色，影响到植物的生长和美观。

因此，在月季大苗缓苗时，我们应该选择一个部分阴凉的地方，避免直接暴露在强烈的阳光下。这可以通过在花园中选择位置，或者使用遮阳网、遮荫网等方法来实现。

Why can't the rose seedlings be exposed to sunlight?

Rose is a beautiful flower that many people love to grow in their gardens. However, for rose seedlings, they require special care and environment during their initial growth stage. One important consideration is to avoid excessive exposure to sunlight.

As newly transplanted plants, rose seedlings usually have fragile and underdeveloped root systems. If exposed to intense sunlight, the combination of bright light and high temperatures can result in rapid water evaporation. This prevents the roots from absorbing sufficient water and nutrients, leading to withering and death of the seedlings.

Furthermore, strong sunlight can also cause leaf burn on rose seedlings. The young and delicate leaves of roses are susceptible to sunburn. Damaged leaves turn yellow, wither, and even fade, affecting both the growth and appearance of the plant.

Therefore, when growing rose seedlings, it is important to choose a partially shaded location, avoiding direct exposure to intense sunlight. This can be achieved by selecting the right spot in the garden or using shading nets or screens.
