A, tree species characteristics:Huang ke of evergreen shrubs or small trees, tree trunks smooth gray, densely branches, four prismatic branches.Leaves opposite, leathery, margin entire, elliptic or obovate, apex rounded or slightly concave, surface light green, green and yellow on the back.Flowers in clusters axillary or branch end, 4 ~ 5 month open, floral green.
It has little sparrow tongue, leaf spoon or oblanceolate, surface dark green, glossy;Pearl boxwood, evergreen, shrubs, leaf shape, luster.Above two trees is graceful, are all making the precious trees bonsai.
Growth habit: neutral, slow growth, resistance to clip, resistance to pollution
Landscape USES: ornamental, hedge
Second, the huang - ecological features
1. Yin xi light resistance, under the condition of indoor and outdoor can keep grow well.Although long-term shaded environment, blade can keep green, but easy to lead to moderate growth or weak branches.
2. The moist, resistant to continuous wet weather around January, but avoid water for a long time.
3. The drought, as long as the surface soil and the soil not completely dry, no abnormal performance.
4. Heat resistant to cold, can withstand the summer sun and resistance to cold of minus 20 degrees Celsius, but should be more hot humid summer ventilation pervious to light.
5. The soil is relaxed, is better to easily fertile sandy loam, potted plants can also vermiculite and peat or soil, strong alkali resistance.
6. Tillering sex is extremely strong, resistant to trim, easy to shape.
7. After autumn light fully and enter a dormant state, to be converted into a red leaf.
8. To the four seasons in a basin or transplanting, summer or new bud germination when transplanting shade should be paid attention to and prevent the soil is too wet, otherwise easy to cause the original leaf defoliation.
Three, huang - form features
Huang Yang as the evergreen trees, up to 8 ~ 10 meters, leaves leathery, positive is dark green, back to light green, in cold winter leaf color is green, no falling leaves.The leaves ovate or elliptic, 5-6 cm long, 4 ~ 5 cm wide, margin in shallow wavy, petiole 1 centimeter or so.Flowers light yellow, 0.1 ~ 1 cm in diam., capsule nearly globose, 4, 1 ~ 2 cm in diameter, fruit is light green when young, sunny slope is maroon, seeds nearly round sphere, in November, mature, mature skin automatically craze, orange-red pursued the seeds of skin exposed, full crabapple tree leaves, far see a house that has interest, beautiful scenery.
Four, huang Yang seed collection and sowing
Liaoning linghai Jiang Mu forest farm based on their geographical location and actual situation, I have a set of mature forest farm of technical measures, seed time in late June to late July, when the skin discoloration, will harvest in time, otherwise the mature seeds are easy to birds to eat.Fell to the ground is not easy to collect, after collect in ventilated dry indoor shade, remove red aril, take off a kind of hard to soft leather, overweight, hard seeds will crush easily.In mid-september, Wells, blisters for 24 hours, planting, ridge 3 cm deep, spread bottom case, covering 0.5 cm to 1.0 cm, rather thin thick "principle, to step on, better combining the seeds and soil, a week before frozen soil filling and a foot of water!Antifreeze and seed dry, reoccupy dry grass curtain!Next year in the soil should be promptly removed after grass curtain, such doing can avoid seed storage in winter.Also avoid the difficulty in seed storage and spring sowing time is not easy to master.This method is simple, more important can reduce the cost is worth promoting.
With seeds of breeding seedlings, variable phenomenon is more obvious, especially the shape of the leaves vary considerably.In the west, there are 50% to 60% of the seedling leaves the same as the female parent, there are 20% to 40% of the nursery stock become pointed leaf blade, 1% to 10% of the seedling leaves become wide.With seed sowing of breeding seedlings, no matter how change, leaf shape on the west of Qiao Hua traits and behavior is almost the same with the female parent of rapid growth.But should pay attention to is that breeding the west don't easily will those leaves type seedling thrown away.
Fifth, the management of nursery stock
Spring from grass curtain after pouring enough water in time, the north spring drought less rain and evaporation is big, every 7 to 10 days for the second time, water, keep the soil moist seedlings out to shovel in time after grass, grass before watering, lest hurt seedlings, thinning out and singling to prevent the occurrence of plant diseases and insect pests, fertilizer 1 to 3 times, 3 years for transplanting, seedling grading, for the management, so can be little seedling cultivation.
Other reproduction methods Liquid is good, cutting and grafting survival rate is high.
Six, huang Yang saplings versatility, good prospects for development, make the human intellect and similar species out of the city, town, gardens, streets, parks, yards, in road, river Banks, fields, often flash his figure, the construction of colorful living environment.Multiply by huang seedling can bring considerable economic benefit to the nursery.
