Cultivation method of Ilex cornuta (points for attention in feeding Ilex cornuta)
Ilex cornuta is an evergreen tree of Ilex, especially cat thorn and tiger thorn. It is produced in the Yangtze River valley in China, parts of the Qinling Mountains and all parts of the south. It grows very slowly, mostly in mixed forests or shrubs on hillsides, valleys and streams. It is cultivated in Qingdao and Jinan, Shandong Province, and has high cultivation value. Let's take a look at the planting techniques in Osback!

Growth habit of bone formation

Broussonetia papyrifera is produced in Jiangsu, Shanghai, Anhui, Zhejiang, Jiangxi, Hubei, Hunan and other provinces. It is cultivated in gardens in cities such as Kunming, Yunnan, and also in botanical gardens in some countries in Europe and America. Like light, slightly tolerant of shade, like warm climate and fertile moist slightly acidic soil with good drainage, not cold-resistant, quite adaptable to urban environment, strong ability to resist harmful gases, slow growth, strong germination and pruning resistance.

Osteogenic propagation technique

1. Sowing: Broussonetia papyrifera can harvest mature seeds from September to10, and the seeds germinate after 3 months of maturity. They are stored in the sand layer and sown in March-April of the following year, and the emergence rate is high. The seedlings of Ilex cornuta varieties with colored stripes will appear atavism and the leaves will turn green.

2. Cutting: Both hard and soft branches are acceptable. Soft branches are generally used in rainy season, and the survival rate is high. Cuttings were cut from plants with rich fruits and vigorous growth, with a length of 12 ~ 15 cm and a depth of 8 ~ 10 cm. After cutting, they are shaded and moisturized. In order to promote rooting and improve the propagation effect of cuttings, cuttings should be treated before cutting, and if possible, the rooting rate can be greatly improved by using ABT2 rooting powder during cutting.

3. Grafting: Grafting propagation of Broussonetia papyrifera is mainly used for the propagation of tree species with colored stripes on their leaves, which is usually carried out before germination in spring. Using Ilex cornuta as rootstock, the survival rate of cutting or budding is high.

Bone structure implantation technique

1. Transplantation: Bone transplantation can be carried out in spring and autumn, preferably in March-April in spring and autumn. Due to the scarcity of fibrous roots of Ilex cornuta, it is necessary to prevent pine cones and cut off some branches and leaves to reduce transpiration, otherwise it will be difficult to survive.

2. Water: Water frequently during the vigorous growth period of bones. Generally, the basin soil should be kept moist and free of water, and leaves should be sprayed with water frequently in summer to facilitate evaporation and cooling.

3. Fertilization: Generally, pancake fertilizer is applied every two weeks in spring, topdressing every month in autumn, no fertilization in summer and/kloc-0 fertilizer in winter.

4. Pruning: Ilex cornuta has strong germination ability and is very resistant to pruning. Unnecessary overgrown branches, sprouted branches and redundant buds can be pruned to maintain a certain tree shape. For the wood to be processed, certain branches can be reserved as needed to facilitate processing and molding.

5. Pot-turning: Pot-turning of Holly bonsai is generally 2-3 years 1 time, usually in February-March in spring, or when the trees enter dormancy after autumn. When turning the pot, you can trim some old roots, apply sufficient base fertilizer, keep 1/2 old soil, and reload the pot.
