1、 Curing method

1. Temperature: it has strong cold resistance and can accept a low temperature of minus 20 degrees. If it is a purple shirt in Northeast China, its growth period is from April to October. During this period, the temperature should be controlled below 30 degrees and the temperature at night should be controlled below 25 degrees

2. Watering: the water consumption during the germination period is relatively large. In case of dry weather, it needs to be watered manually once every ten days to half a month. If it is a plant that is afraid of potted maintenance, it needs to be watered every week. For plants maintained in the open field, it is necessary to do a good job of drainage in the rainy season to avoid waterlogging at the root of the plant

3. Fertilization: for potted plants, rotten fertilizer cake water needs to be used during fertilization, and alum fertilizer water of 1:10-1:15 needs to be used during growth period. The interval of fertilization is 30 days. If the plant needs to change pots, the soil needs to be mixed with base fertilizer when planting pots, which is helpful for the growth of the plant

4. Light: Zishan is a slow-growing tree species that is more suitable for semi shade environment. It likes to live in a warm and humid environment, but does not like to live in places with long light time and high light intensity, especially the seedlings cultivated by seeds, which need shade maintenance. It is relatively easy to accept astigmatism, and the illumination time can be maintained at five hours a day

2、 Breeding skills

1. Reproduction: it can be bred using ovules. First of all, we need to put the collected mature fruit in a basin, mix it with coarse sand and water, remove the outer skin of the ovule, and then mix the ovule into the wet sand for storage for one year, so that the budding rate can reach more than 80%. After completing the above steps, you can plant the seedlings. Level the seedling base and start the drill sowing according to the row spacing of 20cm. After planting, cover it with thin soil and straw, so that it can survive the winter smoothly, and the seedlings can appear in the coming year. After the seedlings grow four leaves, you can sparse the seedlings from time to time, that is, pull out the seedlings with poor growth. You need to start topdressing in May, once a month and out of the nursery in a year

2. Planting: at the end of winter, the planting holes with a row spacing of 2 * 2 meters and a depth of 80 cm should be customized. When planting, the seedlings should be correct, the roots should be stretched, and the soil should be compacted when backfilling

3、 Problem diagnosis

1. Insect pests: Generally speaking, aphids, mites and other pests like to parasitize on the plant most. If found, spray insecticides on the plant in time to kill the insects

2. Disease: during the growth period, the plant is prone to leaf wilt and root rot. if it is found, it needs to be transplanted as soon as possible to avoid further infection

4、 Other issues

1. Edible: not edible

2. Toxicity: non toxic
