Common performance of flowers under fertilizer deficiency

Flowers need to be fertilized in the process of cultivation. If you want flowers to grow well, fertilization is essential. If flowers are short of fertilizer, flowers will behave in a variety of ways. The editor has sorted out several performances of flowers when they are short of fat for you. Interested flower friends can learn about them together.

The main results are as follows: 1. The growth of nitrogen deficiency is blocked, the leaves are small and light, and the leaves are sparse and easy to fall, which affects photosynthesis, so the growth is poor, the plant is small, the branches are few, and the fruit is small and few.

2. The growth of phosphorus deficiency was inhibited, the plant was short, and the leaves turned dark green, gray and dull, with purple spots, and finally withered and fell off.

3. Potassium deficiency leaves showed brown spots, abnormal wrinkles, leaf edge curling, and finally scorched, showing a burning state.

4. The growth of calcium-deficient root system was inhibited, the root system was many and short, the cell wall was sticky, and the root tip cells were destroyed, resulting in decay.

5. Magnesium deficiency causes chlorosis, chlorosis and white flower disease. Magnesium-deficient flowers often begin to fade from the lower leaves of the plant, appear yellowing, and gradually spread to the upper leaves. At first, the leaf veins remain green, the rear veins turn yellow, and soon the lower leaves turn brown until they die.

6. under iron deficiency, the upper tender leaves of branches are damaged, and the lower old leaves remain green. When iron deficiency is light, the mesophyll tissue of flowers is light green, and leaf veins remain green. In severe cases, the tender leaves are all yellow and white, and withered spots appear and gradually scorch and fall off.

7. the leaves of manganese-deficient flowers turned pale and gray at first, and then brown spots were found at the leaf tip, which gradually spread to the base part of the leaves, and finally the leaves withered rapidly, the plant growth became weak, and the flowers could not be formed.

8. Auxin in zinc-deficient flowers was destroyed, plant growth was inhibited and disease occurred. Good zinc nutrition can enhance the resistance of plants to fungal diseases.

9. Sulfur deficiency causes chlorosis, and the leaves of flowers turn yellow, but the mesophyll remains green, which can be different from the symptoms of magnesium deficiency and iron deficiency. Sulfur deficiency begins with red withered spots at the base of the leaves, usually the top leaves of flower plants suffer early, the leaves are thick, the branches are thin and lignified.

10. The growth and development of flowers deficient in trace elements have a greater demand for nitrogen, phosphorus, potassium, calcium, magnesium and sulfur, but less demand for iron, manganese, zinc, copper, boron, selenium, molybdenum and so on. However, the lack of trace elements will also be disadvantageous to the growth and development of flowers. Therefore, it is necessary to apply micro-fertilizer properly in order to ensure that the flowers are always bright.
