1. Temperature: its cold resistance is very strong, and it can accept a low temperature of minus 20 ℃. If it's a purple shirt in Northeast China, April to October is its growth period. The temperature in this period should be controlled below 30 degrees, and the temperature at night should be controlled below 25 degrees.
2. Watering: the consumption of water in the germination period is relatively large. In case of dry weather, it needs to be watered once from ten days to half a month manually. For plants that are afraid of potted maintenance, it needs to be watered every week. For the plants to be cured in the open, the drainage work in rainy season should be done well to avoid the root of the plants from being waterlogged.
3. Fertilization: in case of potted plants, the rotten fertilizer cake water shall be used for fertilization. In the growth period, the alum fertilizer water of 1:10-1:15 shall be used. The interval of fertilization is 30 days. If the plant needs to be changed, the pot needs to be mixed with base fertilizer in the soil, which is helpful for the growth of the plant.
4. Light: purple shirt is a slow-growing tree species that is more suitable for semi shade environment. It likes to live in warm and humid environment, and does not like to live in places with long light duration and high light intensity, especially the seedlings cultivated from seeds, which need shade maintenance. It is easy to receive astigmatism, and the light duration can be maintained in five hours a day.
1. Reproduction: it can be propagated with ovules. First of all, we need to put the collected mature fruit in a basin, which is mixed with coarse sand and water to remove the skin of the ovule, and then mix the ovule into the wet sand for storage for one year, so that the germination rate can reach more than 80%. After the above steps are completed, the seedlings can be sown. The seedling base shall be leveled and the row spacing shall be 20cm. After sown, the thin soil shall be covered and the straw shall be covered, so that the seedlings can survive through the winter smoothly. After the seedlings grow four leaves, the seedlings can be thinned. That is to pull out the seedlings with poor growth and start topdressing in May. Once a month, you can go out of the garden in a year
2. Planting: near the end of winter, according to the row spacing of 2 * 2 meters, 80 cm depth of the planting hole began to customize. When planting, we should make sure that the seedlings are correct, the roots stretch, and the soil is compacted when backfilling.
1. Insect damage: Generally speaking, aphids, mites and other pests are the most favorite to parasitize on the plant. If found, they should spray insecticides on the plant in time to kill insects.
2. Disease: in the growing period, the plant is easy to wither and root rot, if found, it needs to be transplanted as soon as possible to avoid further infection.
1. Edible: not edible.
2. Toxicity: non toxic.
