What is the reason why the leaves of the plant are not green and dull

The first point of light is unreasonable, any plant growth can not be separated from the sun, people are also inseparable from the sun, we raise it to a dark environment indoors, the leafy green plants can not carry out photosynthesis, the color of the leaves will be shallow, and dull and dull, so we have to create a suitable environment for him to see the light, the most basic is to ensure that one or two hours of scattered light every day, so as to ensure that its leaves grow large, thick, dark and shiny.

The second point is proper watering, we raise a plant is not to put it there regardless of it, let it grow all the time, if you want to raise it like this, then you can directly raise a pot of fake flowers plastic flowers are no problem, plants and people, growth is inseparable from water, if it itself is more drought tolerant, we drought he will not die, but its leaves will wilt, the color of the leaves will be light and dull, look at it will not be watery, so it is said to be watered regularly, Before we raise a certain plant, understand its demand for water, adhere to the principle that the soil is about to dry out and water him thoroughly, so that basically any plant will not have problems, as long as the indoor environment is well ventilated, the soil surface will not be a problem when watering, so as far as possible to water reasonably, do not water too much, do not over-dry, as long as our soil is well permeable, the soil surface will not be a problem when watering.

The third point is that the fertilizer should be chosen right, a lot of flower friends raise them to throw it to the one to water a little, so that it does not have problems, this method is wrong, plant growth is inseparable from fertilizer, fertilizer supplementation can make its leaves grow big and bright, for the leaves of the plant we don't need it to flower, what we need is to make it quickly long leaves fast long branches, grow luxuriant, leaves grow big, dark and shiny color, fertilizer as far as possible to choose high nitrogen content, other elements are not missing, For example, the number of flowers is more than 10, so as to get enough nitrogen, the branches and leaves grow fast and grow bigger, there is no lack of other elements, the root system can also be more developed, the most basic fertilizer supplement once a month is essential, of course, if we don't want to buy fertilizer, we can make it at home, common oil crop seeds, soybean cake, peanut cake, soybeans, peanuts and the like with water fermentation, this is a very good high nitrogen fertilizer, foliage green plants like him the most.

Plants lacking nitrogen, magnesium, iron, phosphorus, and potassium will have symptoms of non-green leaf color

1. If the plant lacks nitrogen, the plant will be bright and light green, the old leaves at the base will turn yellow, and it will be brown when dry. The stems are short and thin, with few branches or tillers, and premature senescence occurs. If the fruit tree is deficient in nitrogen, it is manifested as small fruit, few fruit, hard peel and so on.

2. If the plant is deficient in magnesium, it will cause the leaves to turn yellow, sometimes variegated, and there is a certain difference from nitrogen deficiency, the leaf veins are still green, and the leaf veins turn yellow, sometimes purple, and necrotic spots appear;

3. If the plant is deficient in iron, there will be green loss between the veins, which is clear reticulated, and in severe cases, the whole leaves, especially the young leaves, are pale yellow or even whitish. Fruit trees in the north, such as apples and pears, are prone to this symptom;

4. Phosphorus-deficient leaves turn from dark green to copper, and the leaf veins, especially the petioles, are yellow with purple. Flower buds are difficult to form, and the flowering is small, few and light-colored, resulting in poor fruit development and even early wilting;

5. Potassium-deficient plants are short, and the stems are soft and easy to lodging. The leaves are often shrivelled, and the old leaves appear black-brown spots along the leaf edges from the tip of the leaf, and the surrounding leaves turn yellow, while the middle and leaf pulse are still green.

Plants lacking nitrogen, magnesium, and iron will cause yellowing of leaves.

Nitrogen deficiency: The plant is light green, the old leaves at the base turn yellow, and brown when dry. The stems are short and thin, with few branches or tillers, and premature senescence occurs. If the fruit tree is deficient in nitrogen, it is manifested as small fruit, few fruit, hard peel and so on.

Magnesium deficiency: The leaves turn yellow, sometimes variegated (as distinguished from nitrogen deficiency), the veins remain green, while the veins turn yellow, sometimes purple, with necrotic spots.

Iron deficiency: the veins lose green, showing a clear reticulation, and in severe cases, the whole leaves, especially the young leaves, are pale yellow, or even whitish. Fruit trees in the north, such as apples and pears, are prone to this symptom;

The green leaves of the plant are called "green factories". Everyone knows that in order for plants to make organic matter, they must photosynthesize, and of course, chlorophyll must be present.

The leaves of some plants, such as rice, red amaranth, and begonias, are often red or purplish-red. Although these leaves are red, they also have chlorophyll in the leaves. As for the red color of these leaves, it is mainly because they contain red chromanthin, which contains a lot of pigments, and the color is very strong, covering the green.

In addition, many plants that grow on the seabed, such as kelp and seaweed, are often red or brown. In fact, they also contain chlorophyll, but the green color is masked by another pigment, brown pigment.

As for the leaves of some plants, like the leaves of maples and maples, which were originally green, they turn red in the autumn because the chlorophyll is destroyed and the anthocyanins (which are red) are revealed.
