What part of the cactus spines degenerate from?

The spines of the cactus are degraded from its leaves.

Appearance characteristics of cactus:

upper branches broadly obovate or nearly spherical, green to blue, hairless; prickly yellow, with light brown streaks, hard; Barbs, erect. The leaves are diamond-shaped, green. The petals are radial; Receptacle obovate, tapering at base; The perianth is yellow with green ribs in the middle; The filaments are pale yellow; The anthers are yellow; The columella is pale yellow; The stigma is yellowish-white.

Most of the seeds, oval-shaped, have slightly irregular edges.

The spikes of the cactus are the result of the degradation of the plant to adapt to the hot and arid desert environment. The cactus is turquoise in color and beautiful in color, and has a high ornamental value. Plants have good vitality and adaptability, easy to raise, suitable for indoor planting, can be used as decoration, can reduce eye fatigue, and can also purify the air in the room.

Key Value: Medicinal.

Cactus in China as a medicinal plant was first published in the Qing Dynasty Zhao Xuemin's "Compendium of Materia Medica", which recorded: cactus has a light taste, cold has the effect of activating qi and blood, clearing heat and detoxifying, reducing swelling and relieving pain, strengthening the spleen and stopping diarrhea, calming the nerves and diuretic, and taking it internally and externally. Cactus is mainly poisoned by boils, swelling and poison, and can also be used for stomach pain, abdominal pain, acute dysentery, intestinal hemorrhoids, diarrhea, asthma and other symptoms.

Edible. Cactus berries are sweet and sour and edible. The cactus fruit is fragrant and sweet, tender and juicy, and is generally eaten fresh; Mexico and other places also use fresh fruits to process into canned food or alcoholic beverages, and can also be added with honey and fresh milk ice cubes to make juice, and the flavor of ice cream is better.

The spines on the cactus are actually the product of the degeneration of the plant's leaves. The spines of the cactus are formed by the degeneration of the leaves, because the stems of the cactus can replace the green leaves for photosynthesis and can also make nutrients, while the green leaves that are supposed to make nutrients have degenerated into needles and become slender and hard.

Cactus cultivation method

Cacti are cultivated at home, and asexual propagation is mostly used, that is, the division method, the cutting method and the grafting method. Most cactus flowers are very easy to divide seedlings or balls, and their seedlings or balls are pulled out and planted separately, which is very easy to survive.

For some varieties that are not easy to meristem balls, they can be forced to reproduce daughter balls by cutting off. That is, the upper part of the stem of the mother plant is cut off, and the cut part can be used as a cutting, so that it loses the growth point of the upper part and can no longer grow upward. Strengthen water and fertilizer management, and new balls can grow.

Most of the cacti cultivated at home are propagated by cuttings, and the survival rate is extremely high. Cuttings can be done in spring, summer and autumn. Cuttings should be selected not old and tender stems, after the stems are cut from the mother plant, first put in a semi-shaded and ventilated place to dry for 5 to 7 days, and so the incision is dry, the cortex shrinks slightly inward, and a layer of film is generated, and then cuttings, the length of the cuttings is 10 cm, and the depth of the cuttings is 3 cm.

Insert it into the sterilized sandy soil, water it after a few days, and water it slightly when watering to prevent the cuttings from rotting, and the cactus generally takes root after 20 days of cuttings.

The spines of the cactus are formed by the degeneration of the leaves. The cactus thorn is significant for the cactus itself, a product of a protective mechanism designed to adapt to the harsh climate. This thorn belongs to the leaves of the cactus, which reduces the transpiration area of the plant and saves a lot of water consumption.

The spines of the cactus take on many other forms, reflecting intense light and reducing water loss.

Cactus precautionsMost of the cactus flowers are native to desert and open areas, with good ventilation and fresh air. Therefore, in the hot weather of midsummer, the ventilation and cooling of the cultivation site should be done.

The cultivation greenhouse should be in an environment with good air circulation, and more ventilation openings such as windows and skylights should be set up to facilitate ventilation in hot summer weather. If necessary, equipment such as exhaust fans, hair dryers or electric fans can also be installed to enhance the air circulation effect of the environment to promote the safe summer of cactus flowers.

The spines on the cactus are actually the product of the degeneration of the plant's leaves.

The spines of the cactus are formed by the degeneration of the leaves. In order to adapt to desert life and reduce transpiration, the leaves of the cactus become spikes. Cactus is a variant of the cactus family, native to Mexico, the United States and other places, and cultivated in the coastal areas of southern China.

The fleshy stems of the cactus can be used as livestock feed, and its fruit is tender and juicy enough to be eaten directly.

Precautions for cactus farming

Cactus is more drought tolerant, during the growth period to water an appropriate amount, give the right amount of water to meet the growth, not too much watering to cause water damp roots. In winter, as the temperature drops, the growth is slow, and the need for water decreases, so it is necessary to control the watering.

Cacti do not like fertilizer, are very barren tolerant, and long-term non-fertilization will not affect growth. In order to promote the vigorous growth of cactus, you can apply a little thin fertilizer water, and apply a thin and well-rotted liquid fertilizer every half a month during the growing season.
