In order to adapt to the environment in the place of origin, almost every variety has formed the annual inherent physiological habits of dormancy or semi-dormancy. Due to different varieties, some of their dormancy period is in summer, some in winter, and some varieties in summer and winter. Although they have emigrated to a foreign country and bred ten or eight generations or even thousands of generations, this habit remains infatuated. Because of the existence of this habit, the management of this period is different from that of the growing period. If "equal treatment", it is easy to make succulent plants grow poorly, or even rot and die, resulting in failure or loss. Therefore, it is very important for the planting and maintenance of succulent plants to identify the dormancy period of succulent plants and the management of corresponding periods.

Identification of growth dormancy period of succulent plants

Identifying dormant and semi-dormant periods is easy for experienced professional producers and a bit tricky for amateurs. In fact, when succulent plants are dormant, a series of physiological changes occur in the body, which must be shown on the outside. As long as they are carefully observed, the essence is seen through the phenomenon, and they can be judged and identified according to the changes of some characteristics of the plant.

Characteristics of dormancy period of succulent plants:

Body color: 1. The color of the leaves is dull and dull. two。 The leaf color of the whole plant is basically the same. 3. The lower leaves change color, or the whole plant changes color. 4. The color and lustre of stem and shoot are basically the same. 5. The color of the whole plant is the same as that of Daihua and petrochemical varieties.

View root system: 1. The interruption color of the root slightly above the root is basically the same. two。 The root slightly and the middle part of the root is an old root system, and the root diameter is gradually smaller. 3. There is no obvious new root system in the root.

View the growth state: 1. Heart leaves: pointed leaves become wider and extend outward; become shorter and flat-topped; broad-shaped leaves extend outward. two。 There are a small number of fallen leaves, leaf tip or leaf tip withering phenomenon. 3. Completely dormant, the whole plant was deciduous, and the stems of some varieties withered above the soil. 4. The stem tip and branch tip aged and thickened into obtuse angle. 5. The plant growth stagnated.

Characteristics of growing period of succulent plants:

Body color: 1. The new leaves with plush leaves are lighter or darker than the old ones. two。 The leaves are glabrous, the old leaves are smooth and shiny, and the new leaves are fresh and beautiful. 3. The color of stem tip, branch tip and middle part of stem branch is either dark or light, which can be divided into two kinds of color. 4. There are obvious differences in color between the top and the middle and lower parts of belt chemical and petrochemical varieties.

View root system: 1. The root tip is darker and lighter than the middle part of the root. two。 The root tip has a tender shoot 3 to 5 mm long and its diameter is larger than that in the middle part of the root. 3. It has the largest new root system.

View the growth state: 1. Heart leaves: pointed leaves are long and narrow, uneven, and broad ones close or curl in the middle. two。 There are no fallen leaves, withered leaves and so on. 3. Stem tip, branch tip fresh and tender, acuminate into an acute angle. 4. The plant is full of vitality.

Management of dormancy period of succulent plants

When the succulent plant is in the dormant period, the active tissue activity in the body slows down or even stops the absorption, synthesis, conversion and release of nutrient water, and the plant will stop growing. In this period, the following key measures should be taken:

1. Water and fertilizer management: water completely dormant without watering, keep the soil dry: generally dormant to keep the soil moist; semi-dormant appropriate watering mouth fertilizer no matter what kind of dormancy, stop fertilization to avoid fertilizer damage to roots.

two。 Temperature control: due to different varieties of succulent plants, the temperature they need during the growing period is different, and the temperature they need is very close when they are dormant. Practice has proved that the most suitable temperature is 25: 32 ℃ for summer dormancy, 2-5 ℃ for winter dormancy, and 7-10 ℃ for a few cold-resistant ones.
