fertilize是什么意思

When an egg from the ovary of a woman or female animal is fertilized, a sperm from the male joins with the egg, causing a baby or young animal to begin forming. A female plant is fertilized when its reproductive parts come into contact with pollen from the male plant.

To fertilize land means to improve its quality in order to make plants grow well on it, by spreading solid animal waste or a chemical mixture on it.
