Dogwood breeding method
Temperature and light
Dogwood is a warm and warm tree -positive tree species. It has a suitable growth temperature between 20 and 30 ° C and poor growth exceeding 35 ° C. Strong cold resistance and low temperature-18 ℃ low temperature.
The dogwood is more overcast but with sufficient light. It is usually in the middle and lower parts of the hillside, and the yin slope, yang slope, valley, and cross -strait of the river grow well. But in summer, avoid direct light.
Dogwood should be planted in a well -drained soil, which is rich in organic and fertile soil. The soil should be mixed with the right amount of river sand to increase drainage and breathable performance. It is slightly slightly acidic.
Water and fertilizer management
During the growth process, dogwood should have three major irrigation every year. The first time before the Spring Festival sprouting and flowering, the second time in the summer fruits, and the third time before the winter, the dogwood can be safe in winter.

Precautions for breeding of dogwood
Dogwood has breeding methods such as sowing, cutting propagation, grafting and breeding, and press breeding. Because the breeding coefficient of the dogwood is relatively large, the grafting seedlings can be fruitful for 2 to 3 years. The method of grafting can make the dogwood early results and benefit early.
During the growth process of dogwood, there will be diseases such as corner spots, anthracnose, ginkgo disease, gray plaster disease and other diseases, as well as fructile moths (dog meat, carnivores, carrin and meat insects), large moths (debt -avoiding moths), wooden ruler (撩 山 山 山 山 山 山 山 山 山Bridge insects), leaf cicada, thorns, pests, wooden pocket moths, grystums pests, green -legged dew and locusts (locusts) and other insect pests.
