Growth habit edit Euonymus hi light, a little shade, there is a certain degree of cold hardiness in the Huaihe River Basin can be exposed to natural winter, the need to protect wintering in North China, most areas in the northeast and northwest are for pot. Strict requirements on the soil, in slightly acidic, slightly alkaline soil can grow, grow rapidly in the fertile and well-drained soil, branches and more. Common cultivars have the following four kinds: Euonymus (2) Heart of Gold Euonymus (Awens) dry skin taupe, twigs and petioles are yellow, golden yellow leaves of the center. Silver side Euonymus (Albo-marginatus) petioles and twigs were white or gray green leaves very narrow margin with silver stripes. Phnom Penh Euonymus (Ovatus Aureus) margin golden Hokkaido boxwood (new varieties) rounded top, the main characteristics of thick tops, top of the obvious advantages, the backbone obvious straight alone, exhibits excellent characteristics of trees, grow faster, annual growth of up to 70-170 cm, with an average growth of about 70 cm, 5-year seedlings of up to 3 meters. Canopy remains green throughout the winter, cold, drought, a tree can tolerate temperatures of -23.9 ℃. Quoted from Hokkaido, Japan, for planting in North China, northwest and south of the region. [3] ⑶ Occurrence area in Hebei Renqiu insects a year a generation, to fertilize the female adult fixation overwinter in 1 to 2 years old branches. In the female egg is produced, each female can lay 1000-2000, more up to 3000. Overwintering female adults between April 3 to begin feeding Buxus role in mid-April and late parasites increases rapidly, 5 months late start spawning, egg up to 25-30 days in late June to July In late as nymphs hatching. The nymphs hatch more quiet early in the female's 蚧壳 volts, after several days before dispersing out, climbed more veins on both sides of the blade damage, a few days later that secrete a waxy form Kuwana shell stationary. Females mature later moved back branches from leaves and mate with males, after wintering in branches that fixed. Male nymph on August, began in mid-pupation, pupal period is about 15 days in late August, early September emergence as adults. After the male adult emergence, from the wax shell rear exit, looking for females and mate with them, about the life of two days. Female, male after mating, the male death, in order to fertilize the females overwinter. During the eggs hatch, the case of rain, air humidity, temperature normal, hatching eggs and larvae survival rates are high lobular boxwood, Buxus up to 100 percent how much, when heavy damage. Conversely, the lack of rain during this period, high temperatures and dry, a large number of eggs and newly hatched nymphs will dry out and die under the parent shell, then harm will light; female adults during the winter Buxus supply, more rain and snow, ice formed on the branches Under the circumstances, the natural mortality rate is high.
