What are the fertilizer absorption characteristics of flowering plants?
Flowering plants mainly absorb nutrients through their roots, and different plants absorb mineral elements differently, each with its own characteristics. Today, the editor will introduce them to you.
(1) The fertilizer absorption of flowering plants mainly concerns the relationship between the roots' absorption of mineral elements and their absorption of water. Mineral elements can only be absorbed by plants when dissolved in water. Water directly affects the absorption and transport of mineral elements, but there is no direct proportional relationship between the two; each has relative independence.
(2) Plant roots have the characteristic of selective absorption of mineral elements. In the fertilizer absorption of flowering plants, the number of salt ions absorbed by the roots is not proportional to the ions in the solution. Even the anions and cations of the same salt enter the plant in different proportions, causing the composition and pH of the nutrient solution to gradually change.
(3) Single-salt toxicity and the antagonism between ions. If any plant is placed in a nutrient solution containing a single salt, it cannot grow; this is called single-salt toxicity. If a small amount of other salts is added to it, the single-salt toxicity can be eliminated. This phenomenon, in which ions can mutually eliminate toxicity, is called antagonism. Therefore, when determining and selecting a nutrient solution formula, the formula should be chosen according to the characteristics of different species.
That is all for now. I believe everyone has gained some understanding. I hope this article is helpful to everyone.
