Cultivation techniques of Aloe

1 Aloe is selected for warm and humid climate, which is not cold resistant The room temperature in winter shall not be lower than 5 ℃, and it is suitable for drying in dormancy period Like good drainage, fertile sandy loam The soil requirement is not strict, it is resistant to drought and salt alkali, and it does not need large water and fertilizer management But like the sun, do not bear the shade, in the shade environment, do not blossom 2 The propagation method is cutting, splitting or sowing Often does not produce seeds (1) seed sowing method seeds are sown in spring, seedlings need to be raised in sand tray, and then transplanted (2) the new tillering plants around the mother plant were cut off from the underground stem of the mother plant in the early spring combined with the basin changing method, which was used as the seed plant cultivation However, the number of tillers and reproduction of this method is small (3) generally, cuttage is used for propagation The method is to cut the small lateral branches between the base of main stem and leaf axil between spring and summer Cut 10-15 cm long buds from the base with a knife, place them in the shade for 1 day, dry them slightly, and then insert them into the culture soil The planting depth is 3-4cm, watering can be done after one week, and rooting can be done in about 20-30 days The trunk can also be cut The best cutting time is spring, so as to survive the winter safely In frost areas in the north, plastic sheds or warm rooms should be used Do not water more in winter to prevent rotten roots Generally planted in the spring of the second year The plant grows rapidly in summer and autumn In the first few years after cutting, the pot soil should be changed once a year when leaving the room in spring (with sand culture soil) At the same time, remove the old plants and plant the young plants During the slow seedling period after potting, water should be controlled and the pot should be placed outdoors in summer Well ventilated half shade, fully watered After autumn, gradually control the watering In winter, set a sunny place not lower than 5 ℃ in the room, keep the basin soil dry properly, and then you can survive the winter safely 3 After the seedlings are divided in the field, they should be irrigated, but not too wet When it is dry in summer, it should be irrigated once every 1-2 days and once every 3-4 weeks to remove weeds in the field Move into the greenhouse in winter to prevent cold, and avoid direct sunlight in summer 4 Harvest and process in the season of vigorous growth and development of aloe, harvest in batches the leaves with large growth in the base and middle (the tender leaves on the tip cannot be picked) Remove the leaves, wash them, slice them, put them into water of the same weight, cook them for 3-4 hours with high fire, filter them with gauze, and concentrate the filtrate into a viscous state Fresh leaves can be picked at any time.
