First, culture soil
The soil is required to be porous, air-permeable, and well drained, but it has a certain water retention capacity and is neutral or slightly acidic. The highland ball species (Month World Genus, Yuehuayugenus, and Euphorbia genus) and Rock Peonies can add a little more ash and small weathered rocks. Large columnar species can be mixed with large-sized quartz sand to fix the plant.
Second, transplant and plant
It should generally be done during the recovery period when the plant's dormancy has just ended. Root before planting. After the roots have been cleaned, they must be aired for a few days and then planted in a moist culture soil. After the seeds are properly shaded, do not rush to water. Do not apply fertilizer within one month.
Third, the adjustment of temperature and light
Cactus and succulents generally prefer warmth and a large temperature difference between day and night. In addition to the type of cactus of the epiphytic type and the 12-volume species, the light should be sufficient, but soft. For this reason, except for a few flat stem sections and tall columnar species and some plants of the genus Agave, they should generally be cultivated in greenhouses all year round.
The type of epiphytic type should be shaded except for winter, combined with cooling in summer, and the degree of shading should be 50% to 70%. Although pods and lotus flowers have a certain degree of cold resistance, keeping warm in the winter is beneficial to flowering in the following year. The amount of cultivar used as the rootstock that is cultivated in large amounts is not tolerant to cold, and it is required to maintain at least 5°C in winter and require sufficient exposure to sunlight.
Most terrestrial types of cacti thrive most vigorously during the day from 28°C to 35°C and at night from 10°C to 15°C. When the indoor temperature is often higher than 35°C to 38°C, the growth stagnates, and part of the species of highland ball and wool column is also very likely to rot. Therefore, it is necessary to cool down, but it is not possible to reduce too much light like the epiphytic type in order to cool down.
Most terrestrial type species can tolerate low temperatures of 2°C or even 0°C during the winter when basin soil is kept dry, but they cannot be directly affected by snow. Caribbean species of the genus Caulis in the Caribbean and winter flowering spherical species are maintained at higher temperatures.
Succulent plants growing in summer can basically adjust the temperature with reference to terrestrial cactus. Their requirements for light are relatively low, some species with enlarged stem bases are not tolerant to cold, and winters should maintain higher temperatures.
Succulent plants growing in winter are kept cool during ventilation during the summer period of dormancy. In winter, sunlight is required and the minimum temperature is maintained above 7°C.
Fourth, watering and fertilizing
Watering should be done according to its growth state. Regardless of the type of winter hibernation or hibernation in the summer, watering of the basin is stopped during the dormant period. However, the types of hibernation in the summer must be tanned in the walkways, etc. to maintain a certain degree of air humidity. Plants that thrive during vigorous growth should fully meet their water requirements. Small seedlings need more watering, less big balls (number of times), less land type, more epiphytic type, more flowering time, less flowering, less fruit and less water, more thin leaves The leaves are thick and little less poured.
Fertilization should be carried out during the period of vigorous growth and budding. Organic fertilizer must be fully cooked. When fertilizer is applied, the ratio of nitrogen, phosphorus and potassium is 5:15:10 or 5:10:10, and a small amount of trace elements should be mixed.
The fertilizer is rather light and not strong, and it can be applied several times when necessary. Those with root damage, poor growth, and wounds on stems and leaves are prohibited from fertilizing.
V. Pest Control
Prevention and control of pests and diseases is mainly prevention. First, the environment should be tidy. Exotic plants must be strictly controlled, and they must be placed in the shed when there is no pest or disease. In the early winter, early spring, and rainy days, the spraying of medicines in the sheds had a multiplier effect. In addition, there is a good preventive effect on the disinfection of cultured soil.
Commonly-used agents include mainly fungicides for preventing and treating diseases (such as carbendazim, thiophanate, chlorothalonil, zeocin, etc.) and insecticides (such as omethoate, miticide, marathon, and fenvalerate). Etc.) Two categories, can be prescribed for the remedy. The concentration of the drug should be strictly controlled according to the instructions for use, especially insecticides. If the concentration is a little thicker, it will produce phytotoxicity. This is particularly sensitive to the crown and some of the Euphorbiaceae succulents.
The spray should be sprayed several times before it is effective (interval 2 days). After the same drug is used twice, it needs to be changed. The use of a pesticide for a long period of time can easily produce drug resistance.
