How to raise common succulent plants?

Succulent plants refer to a certain part of plant vegetative organs, such as stems or leaves or roots (a few species have both), which have well-developed parenchyma for storing water and appear to be thick and succulent in appearance. Most of them grow in arid areas, do not absorb water from the roots for a long time every year, and live only by the water stored in the body. Sometimes people like to call such plants desert plants or psammophytes, but it is not quite exact that many succulent plants grow in desert areas, some do not grow in deserts, and there are many plants that are not succulent plants in the desert.

How on earth should succulent plants be raised? As there are many kinds of succulent plants, the editor will not introduce their breeding methods one by one here. Here, the editor introduces several common breeding methods of succulent plants, and most of the others are similar.

Culture methods of succulent plants in Sedum family

Crassulaceae plants are perennial succulent herbs, blooming in summer and autumn, small and luxuriant flowers, a variety of colors. The epidermis has wax powder, stomatal subsidence, can reduce transpiration, is a typical xerophyte, strong asexual fecundity, the so-called leaf picking can plant roots. Crassulaceae plants are short, because they are fleshy and consume little water and fertilizer, so they are easy to plant and watch. Crassulaceae plants have become the first choice of roof greening because of their short resistance to wind, no need for a lot of water and fertilizer, and resistance to pollution.

1. Planting: dry planting in fluvo-aquic soil, not dry planting in wet soil, mix some moisture in the soil, do not stick to the hand, do not pinch into a ball, wait for watering slowly, give the plant time to adapt to new soil and new roots, do not expose to the sun at the initial stage of planting, but should have bright scattered light.

2. Soil: keep water and breathable, find a balance point, do not accumulate water, need to be breathable. Commonly used formula: peat, perlite, vermiculite, light stone 1, 1, 1, 1, 1, 1, 1, 1, 1, 1. If these things can not be found, you can use Cuiyun beautiful soil mixed with small particles of blue stone or phytolith or other granular things, beautiful soil is a kind of composite medium, but it is a bit too water-retaining for succulent plants, so mix some particles to balance it.

3, illumination: most crassulaceae plants like plenty of sunshine, the initial colonization needs bright scattered light, do not expose to the sun, and need shading at noon in midsummer to prevent burns.

4, temperature: crassulaceae is relatively hardy, general varieties above zero will not have greater damage, 5-30 degrees plants are more cool, the greater the temperature difference, the better.

5, moisture: do not fixed quantity, if six or seven centimeters of the soil layer, then the surface layer of two centimeters dry can be irrigated, that is, the bottom soil has 40 to 50% moisture, too dry hurt the root, too wet retting root, if not sure, then usually insert a toothpick inside, at any time to grasp the soil moisture. Winter watering can be in the sunny noon, spring and autumn evening or early morning watering, when the sun comes out, the soil has been relatively dry, to avoid too heavy moisture stuffy steaming, summer water control, water supply can be in the cool and sunny evening. With regard to this, everyone is different. I have personally seen the ancestor teacher in Jinan pour water into the Martian rabbit in the greenhouse at the end of June at noon. Even if this thing is not dormant in summer, it is surprising enough. Maybe Yigao people are bold.

6. Ventilation: pay attention to ventilation to avoid the coexistence of high temperature and high humidity and low temperature and high humidity.

Culture methods of succulent plants in Cactaceae

Cactus plants are easy to reproduce and can be sown, cut or grafted. Most of them are cultivated as ornamental plants, but they are cultivated as cash crops in Mexico and Central and South America. The fruits are rich in nutrients and vitamins and can be eaten as fruits. Tender stems can be used as vegetables or candied fruits.

1. Watering: terrestrial cacti have obvious growth period and dormant period, which should be watered during the growing period, less or even no watering during the dormant period. For epiphytic type, if the winter temperature is kept above 12 ℃, it can be watered and sprayed all the year round; if the winter temperature is kept below 12 ℃, watering can be reduced and stopped. Water temperature should be close to soil temperature as far as possible, early (before sunrise) and late (after sunset) in summer, from 10:00 to 11:00 in winter, and directly onto basin soil, otherwise the appearance of thorns will be affected. In addition, it is necessary to sprinkle water on the ground in summer to increase air humidity.

2. Fertilization: to master the principle of fertilization: timely, appropriate amount, depending on the object. Fertilization is carried out in spring and autumn, and once every 20 days, it should be carried out in the early morning or evening on a sunny day. If the basin soil is dry, sprinkle some water on the basin soil and then apply fertilizer with a concentration of 0.05%-0.2%. The effect is better if it is watered once the next morning. Terrestrial fertilization requires fertilizers rich in potassium and phosphorus and less nitrogen, while epiphytic fertilizers require more nitrogen fertilizer.

3. Illumination: terrestrial type prefers plenty of sunshine, especially in winter. Generally, tall, cylindrical and flat cacti are more resistant to strong light and can be placed outdoors without sunshade in summer, while smaller spherical ones prefer semi-overcast conditions in summer, covering the top growing point of Jinzhu with a circular plastic film in June and August in summer high temperature season, so that all parts of the sphere grow evenly. Epiphytic cacti require semi-overcast conditions all the year round.

4. Temperature: the optimum temperature for cactus growth is between 20 and 35 ℃. The terrestrial type does not require a high temperature during the dormancy period in winter, but the temperature can be maintained at 4: 7 ℃ while keeping the basin soil dry. Epiphytic type, however, requires a higher temperature in winter to maintain a temperature of 10-13 ℃ or higher. When the cactus reaches 30: 35 ℃ in summer, the growth rate of most cacti slows down, and sometimes some kinds of stems turn yellow or burn, so the sun must be shaded and more water must be sprinkled on the ground to lower the temperature.
