The leaves are divided into several stages of growth, 6 stages of plant growth

The six stages of plant growth were slow seedling stage, vigorous growth stage, flower bud stage, flowering stage, fruiting stage and fruit drop stage. During the seedling slowing period, it is necessary to ensure that the environment is cool and ventilated, and the soil needs to be moistened in the evening growth period, and an appropriate amount of top dressing. In the bud stage and fruiting stage, the frequency of watering and fertilization should be adjusted appropriately according to the growth of the plant, so as to make the plant grow better.

The process of re-adaptation of limb plants after transplanting and environmental change during the slow seedling stage is called the slow seedling stage. During the slow seedling period of the plant, it is necessary to ensure the coolness and ventilation of the environment, and it is not appropriate to apply fertilizer during the slow seedling period.

The vigorous growth period refers to the period of time when the plant grows more vigorously, and the watering needs to be used in the vigorous growth period. Appropriate fertilizer can also be added. For plants dominated by foliage, nitrogen fertilizer can be appropriately added, and phosphorus and potassium fertilizer can be appropriately added for plants dominated by flowers and fruits.

In the bud stage, the plant has a higher demand for water and fertilizer, and the growth of flower buds and fruits consumes nutrients, while the growth of leaves is the accumulation of nutrients. If you find that the soil is dry, you need to water it. The frequency can be adjusted appropriately according to the growth of the plant and the change of temperature.

During the dormant period, when the plant rests, growth stops almost completely, and even leaves fall off. Fertilization can be stopped during the dormant period of the plant, but it is necessary to ensure that there is sufficient water.

The flowering period refers to the process of the plant from flowering to flowering, and the flowering period is generally 5 to 14 days. The length of the flowering period, as well as the morning and evening, is related to the local climate, with earlier flowering and shorter flowering periods when the temperature is higher. Cooler or more rainy days, late flowering, and longer flowering periods.

The fruit drop period refers to the period when the fruit falls off due to physiological and climatic reasons after fruit set. During the fruit drop period of the plant, nitrogen, phosphorus and potassium fertilizers should be added under the tree 20 to 30 days in advance. At the same time, it should be watered immediately after top dressing, so as to facilitate the fertilizer effect as soon as possible.

The growth of plants is 6 stages of slow seedling stage, vigorous period, flower bud stage, flowering period, fruiting period and dormant period, when the plant is in the slow seedling stage, it should be placed in a ventilated astigmatism place, and when the vigorous growth period and flower bud stage, it will be placed in a sunny environment to promote the smooth flowering and fruiting of the plant.

stages

There are 6 stages of plant growth, namely slow seedling stage, vigorous growth stage, flower bud stage, flowering stage, fruiting period and dormant stage.

2. Provide light

Plants in the vigorous period, bud stage, flowering period and fruiting period, the demand for light is higher, it needs to be placed in an environment with sufficient scattered light, so that the plant receives full sunlight, promote the growth of flowers and fruits, pay attention to the slow seedling stage and dormant period, do not let the plant be illuminated by strong light, otherwise it will lead to plant death.

3. Control the temperature

In the process of maintaining plants, it should be placed in an environment between 10-30 degrees to prevent the plant from stopping growing due to high or low temperatures, pay attention to the need to ventilate and dissipate heat for the plant in summer, and place it in a warm room for overwintering in winter.

4. Apply fertilizer

In the process of maintaining plants, after the slow seedling period, it is necessary to apply a diluted decomposed organic fertilizer to improve the fertility of the soil, promote the growth of plants, and in the later stage of maintenance, it is necessary to supplement liquid fertilizer for plants every 15 days to maintain the growth of branches and leaves, pay attention to the dormant period, can not fertilize plants, otherwise fertilizer will be produced.

The way the leaves are arranged on the stem is called leaf inflorescence. Through a certain leaf sequence, the plant body makes the leaves evenly and appropriately arranged, fully receiving sunlight, which is conducive to photosynthesis.

Fascicled: Two or more leaves are born on a stem with extremely shortened internodes, which is called a cluster. For example, Masson pine is a bunch of 2 needles, whitebark pine is a bunch of 3 needles, and ginkgo biloba and cedar have multiple leaves in clusters. In some herbaceous plants, the stems are extremely shortened, the internodes are not distinct, and the leaves appear to grow in clusters from the roots, called basal leaves, such as dandelions, plantainium.

Basal leaves often gather to form rosettes, which are called rosettes.

Alternate A leaf is born on each node of the stem, called mutual, such as camphor and sunflower. The leaves are usually distributed in a spiral pattern on the stem, so this leaf inflorescence is also called a spiral leaf inflorescence.

Opposite: Two leaves are born opposite each node of the stem, which is called opposite, such as privet and caryophyllus. On each node of some pairs, two leaves are arranged on both sides of the stem, which is called two rows of opposites, such as Metasequoia. The upper and lower leaves on the stems and branches are staggered at a certain angle, and are usually arranged at right angles, which is called interactive opposites, such as privet.

Whorled is the birth of three or more leaves on each node of the stem, which is called whorled. For example, oleander is three-leaf whorls, 100 are four-leaf whorls, and seven-leaf and one-branch flowers are 5 11 leaf whorls.

Among the various plants, the vast majority of plants have one leaf inflorescence, and some plants will grow two leaf inflorescence types on the same plant body. For example, juniper and gardenia have two kinds of leaf inflorescences: opposites and three-leaf whorls; Crape myrtle and wild stork have two kinds of leaf inflorescences: alternate and opposite; Snapdragons can even see three types of leaf inflorescences: alternate, opposite, and whorl.

The three growth forms of the leaves are opposite, alternate, and whorl.

The three ways in which the leaves grow are opposite, alternate, and whorl.
