The growth of any plant needs phosphorus, potassium, calcium, magnesium, iron, manganese, zinc, sulfur and trace elements, and fertilizer can meet the growth of plants. Through NPK fertilizer production process, a variety of nutrients required by plants are mixed together to make particles, which meet the multiple requirements of plants.
Fertilizer effect on plant growth
1. Phosphorus. Phosphorus is the catalyst of plant growth, which can make the plant grow tall, its growth is inhibited due to lack of phosphorus, the plant is short, the leaves become dark green, dark and lusterless, with purple spots, and finally wither and fall off.
2. Potassium. Potassium mainly affects the growth of plant leaves. The leaves lacking potassium appear brown spots, abnormal wrinkles, curly leaf margins, and finally scorched, which looks like burning.
3. Calcium. Calcium affects the downward extension of plant roots, the growth of calcium deficient roots is inhibited, the roots are many and short, the cell walls are sticky, the root tip cells are damaged, and rotten.
4. Magnesium. Magnesium deficiency causes chlorosis, yellowing and white flower disease. Mg-deficient flowers often begin to fade from the lower leaves of the plants, appear yellow, and gradually spread to the upper leaves. Initially, the veins remain green, the latter veins turn yellow, and soon the lower leaves turn brown until they die.
5. Iron. In case of iron deficiency, the young leaves in the upper part of branches are damaged, while the old leaves in the lower part are still green. In case of slight iron deficiency, the mesophyll tissue of flowers is light green, and the veins are green. In case of serious iron deficiency, all the young leaves are yellow white, and there are dry spots and they gradually scorch and fall off.
6. Manganese. Manganese-deficient flowers. The leaves of the manganese-deficient flower turned pale with some gray. After that, brown spots were found at the tip of the leaves, which gradually spread to the basic parts of the leaves. Finally, the leaves quickly withered, the plants grew weaker, and the flowers could not form.
7. Zinc. The auxin in the zinc-deficient flowers is destroyed, and the plant growth is inhibited and disease is caused. Good zinc nutrition can enhance the plant's resistance to fungal diseases.
8. Sulfur. Sulfur deficiency causes green deficiency, and the flower veins are yellow, but the mesophyll tissue remains green, which can be distinguished from the symptoms of magnesium and iron deficiency. Sulfur deficiency begins with red blemishes at the base of the leaves. Usually, the top leaves of flower plants are damaged early, with thick leaves, thin branches and lignification.
Each nutrient has a different effect on plants. In industry, these elements are combined together according to the characteristics of crop growth, and granulated by using a double roller fertilizer granulator to supplement nutrients required for plant growth.
