Second, the ideal soil. Aloe vera is a "desert lily" that grows in a harsh desert. Strong vitality, no need to prepare special soil. It can adapt to any soil except clay and hardened ground which are not suitable for the healthy growth of aloe. Based on this, as long as the soil is broken and some sand is added to make it have good porosity, permeability and drainage, aloe can thrive. The function of sand is to facilitate drainage and prevent root rot; The ideal soil for aloe planting is mainly composed of swamp soil and sandy soil. Adding humus soil, plant ash and shell pieces can make the ideal soil for aloe growth.
Third, practice essentials. Aloe can be planted from spring to autumn, but if it is planted before first frost, in rainy season or in summer when the temperature is above 30 degrees, even the vitality of aloe will be adversely affected. Therefore, aloe planting should try to avoid these periods, and frost-free May is better. If you plant it in a flowerpot, you can buy it in March-April. If there is a greenhouse or a greenhouse with thermal insulation facilities, it can be cultivated all the year round. When planting, it should be carried out in a place without direct sunlight, and the roots should be cleaned as much as possible to avoid injury. Too long roots should be cut off, then prevent them from entering the seedling pit or pot, and then gently put the soil. After the soil is put away, gently press the topsoil by hand, and then water it thoroughly at one time, without watering for one month.
Fourth, fertilization methods Aloe growth does not require a lot of fertilizer, and there is no need to worry that Aloe will wither because there is no fertilizer; However, if too much fertilizer is applied, it will rot its roots and lead to its death. Therefore, if the soil contains fertilizer, there is no need for fertilization at ordinary times; If it is raw land and needs fertilization, chicken manure and oil dregs can be mixed into the prepared soil half a month before planting aloe, and mixed into the soil according to the ratio of 1 500g/m2 to make it rot; Topdressing 5438+ 10 from September to June, and applying a small amount of organic fertilizer to aloe roots is just right; The larger aloe should be fertilized every 2 months; In order to make it blossom, some phosphate fertilizers such as oil, chicken manure and rice bran should be added every 10 day. Winter (11-March) is the period when aloe stops growing, and fertilization should be stopped during this period.
Verb (abbreviation of verb) water aloe leaves. Aloe leaves have the function of storing water. They were originally grown in the desert and have strong drought tolerance. If planted in the ground, the dug soil has drainage capacity. If planted in the ground, the deep-dug soil has both drainage capacity and water retention capacity, and does not need watering. Of course, if it doesn't rain for a long time and the soil surface cracks, it should be watered in time according to the situation; When transplanting aloe in spring, it is not advisable to give too much water. Water can be watered once every five days. If it rains continuously, the watering days need to be extended. The temperature is low at night in spring and autumn. In order to prevent the residual moisture in the soil from freezing aloe vera, watering should be carried out in sunny morning. On the other hand, in the hot summer, the moisture contained in the soil is heated, and the root of aloe vera will be hurt if the ground temperature rises too high, so watering should be done after sunset instead of in the morning; In winter, the climate is cold, and aloe enters a dormant state, so watering should be stopped. In a word, the most important thing in aloe cultivation is not to use too much water, otherwise it will dilute beneficial ingredients and medicinal ingredients, and in serious cases, it will rot the roots and die, so special attention should be paid.
Six, overwintering technology. Aloe vera from South Africa is heat-resistant and cold-resistant, and wintering is the key technology. According to China's situation, there is no wintering problem in Guangdong, Guangxi and southern Fujian. In the south of the Yangtze river basin, it is necessary to build a greenhouse for wintering; On the other hand, potted aloe in the courtyard, balcony and indoor can overwinter in the sun or in the air, that is, after entering 165438+ 10, pay attention to moving the flowerpot to a sunny place indoors and keep warm at night, or control the water supply of aloe after entering 165438+ 10, until the soil is completely.
Fertilization methods of potted aloe are mainly base fertilizer and topdressing. The base fertilizer is to mix the fertilizer and the substrate fully before filling the pot. In general, the proportion of organic fertilizer in the substrate is about 10: 1, and then it is evenly mixed and put into the pot. When organic fertilizer is used as base fertilizer, it must be fully fermented in advance, otherwise it will burn seedlings and hurt potted aloe.
After potted, topdressing during the growth of aloe. Topdressing should be carried out after the fertilizer solution is quenched. Generally, it is irrigated with urea with concentration less than 2% or 1% calcium superphosphate supernatant. When topdressing, the fertilizer solution should not be too concentrated, otherwise it will cause "fertilizer damage", especially when foliar spraying is used for topdressing outside the roots, the fertilizer concentration should not exceed 0. 1%. Topdressing can generally be applied every 20 ~ 30 days/kloc-0 times, or according to the growth of potted aloe and different seasons. Generally, topdressing grows faster in spring and autumn, and the number of topdressing can be increased appropriately. Growth is slow in winter, so you can apply less fertilizer or even no fertilizer.
Water requirement of potted aloe is different from other potted plants. Aloe is very drought-resistant, even if it is not watered for 3 to 5 months, it will not die. But we can't unilaterally think that aloe likes drought. Although aloe still survives without watering for a long time, its growth is restrained, its leaves wither without juice, and its utilization value is greatly reduced. Therefore, it is advisable to water aloe to see dry and wet. 48 respondents:
