Name: White wax

Alias: White wax, Chinese wax, insect wax, Sichuan wax, yellow wax, beeswax, green palm tree, white wattle

Family: Oleaceae, genus

Species: street tree/deciduous tree

在春天土球:1:7, autumn and winter, 1:8 in summer

Branch point: 2.5~3.2 meters optional

Growth temperature: 16~32 degrees

Nursery method: sowing, grafting

Planting season: Planting before germination in spring and autumn; planting in the second winter; planting in the third summer with 55-80% survival rate.

Main features:

In the cold and dry climate in the north in winter, only a few tree species are suitable for street trees. Baila is one of them, from Shandong, Henan, Hebei, Shanxi, Beijing, Tianjin, to Xinjiang, Ningxia, Qinghai, Gansu and other places in the northwest, regardless of planting For fertile soil, or barren salt-alkali soil with a shortage of water, even sand and gravel soil, as long as there is a little water, white wax can keep a strong inventory and grow vigorously. Its main advantages are cold tolerance, drought tolerance, extreme heat tolerance, and less pests and diseases. The tree is beautiful, tall and straight, and grows fast. It is one of the commonly used trees in the north. It has strong anti-pollution resistance and certain resistance to sulfur dioxide, and can be planted in heavily polluted factories, streets and highways.

Nursery management:

Briefly talk about important issues such as tree cultivation, planting row spacing, watering and fertilization. As for the details of planting and grafting, I won't talk about it here. It takes some effort in the early stage of planting pewter, and it can be managed extensively in the middle and late stages. Simply watering, fertilizing, and pest control are enough.

The canopy must be trimmed three times before it can be fully formed. Fertilization Use compound fertilizer 4 to 5 times a year, bury the roots. The time is 2~3 times in spring and summer, and 1~2 times in summer and autumn. Choose the time according to the climate of the year. If conditions permit in winter, organic fertilizer can be spread on the ground. Decomposed chicken manure, pig manure, cow manure, etc. are all very good fertilizers.

Keep the watering dry without watering, and pour thoroughly. It is recommended to lay drip irrigation channels to facilitate watering at any time. High efficiency and low cost are worth considering for new nurseries.

Key points of project planting:

The problem of planting in spring and autumn is not too big, as long as the water is enough, pewter can easily survive. The survival rate of planting in summer is low, and sometimes it is necessary to plant. based on many years of experience in Changjing Gardens, the experience of planting green seedlings in off-season is summarized: first, the soil ball is large; second, the seedling, transportation, and planting take a short time; third, immediately after planting Most of the leaves are removed, most of the branches are trimmed, and the main skeleton branches are left; the fourth is to water frequently, the summer is hot, the trees are easy to dry out, and when they are planted, the water is not enough.
