雪松要怎么样的才好呢？怎么样的雪松价格才是最公道的，南京金彪苗圃场来告诉你。
常绿乔木，树冠卵形。树皮灰绿色，平滑不开裂。枝条开展，光滑无毛。单叶对生，卵形或卵状披针形，先端渐尖，基部楔形或近圆形，全缘，表面深绿色，有光泽，无毛，叶背浅绿色，革质。6～7月开花，花白色，花冠裂片与花冠筒近等长，圆锥花序顶生。浆果状核果近肾形，10～11月果熟，熟时深蓝色，有白粉。
1、采种：女贞4月～5月开花，11月～12月种子成熟，幼稚时果皮呈黑色，要适时采收，果实幼稚后并不自行脱落，可用高枝剪剪取果穗，捋下果实，将果实浸水，搓去果皮，洗净，阴干。如不立即播种，可装袋干藏或用2份湿砂和1份种子混合贮藏。
2、育苗：女贞可用收获和扦插两种方法育苗，得播种育苗较为普遍。
1．播种育苗3月上旬至4月中旬播种。圃地土壤要求不严，只要疏松肥沃即可。收获前将去皮的种子，用温水浸种1天至2天，然后收获，条播或撒播。条播行距为20厘米，覆土1.5厘米～2厘米，每亩收获量为7公斤左右。因为女贞出苗时间较长，约需1个月，收获后最好在畦面盖草保墒。小苗出土后要及时松土除草，苗高5厘米时进行间苗，小苗怕涝，要注意排水，但过分干旱时也要灌水，按常规管理追肥12次。每月除草1次。1年生的苗高可达到50厘米。如培养大苗，需换床种植，经2年～4年出圃。
2．扦插育苗可在11月间剪取春季生长的枝条埋藏，次年春二、三月取出扦插，插穗粗0.3厘米～0.4厘米每穗长1518厘米左右，上端平口，下端斜口，上部留叶12片，将插穗插入土中2/3株距10厘米，插后约2个月生根，当年苗高达7090厘米。
高杆女贞枝叶清秀，终年常绿，夏日满树白花，又适应城市气候环境，是长江流域常见的绿化树种；常栽于庭园观赏，广泛栽植于街坊、宅院，或作园路树，或修剪作绿篱用。对多种有毒气体抗性较强，可作为工矿区的抗污染树种
Evergreen trees with ovate crown. Bark gray green, smooth without cracking. The branches are smooth and glabrous. Leaves opposite, ovate or ovate-lanceolate, apex acuminate, base cuneate or suborbicular, entire, surface dark green, lustrous, glabrous, abaxial light green, leathery. Flowers 6~7 months, whitish, corolla lobes nearly equal to corolla tube, terminal panicle. Berry shaped drupe near kidney shaped, fruit ripening in 10~11 months, dark blue in maturity, and white powder.
1. Seed collection: Ligustrum lucidum blossoms from April to May, and matures from November to December. The skin is black when it is young. The fruit should be harvested at the right time. The ears can be cut with high branches and the fruit can be swabbed, rinsed and dried. If it is not sown immediately, it can be bagged or dried or mixed with 2 wet sand and 1 seeds.
2, seedling: Ligustrum lucidum can be harvested and cuttage in two ways, and seeding and seedling raising is more common.
1. sowing and raising seedlings from early March to mid April. The soil in the nursery is not strict, so long as it is loose and fertile. Before harvest, peel the seeds, soaking them in warm water for 1 days to 2 days, then harvest, drill or broadcast. The drill spacing is 20 cm, covering 1.5 cm to 2 cm, and the yield per mu is about 7 kg. Because Ligustrum lucidum has a longer emergence time, it takes about 1 months. The seedlings should be loosened and weeded in time after unearthing. When the seedlings are 5 centimeters high, the seedlings are afraid of waterlogging. Drainage should be paid attention to, but water should also be irrigated when drought is excessive, and fertilizer should be applied 12 times according to the routine management. Weed 1 times a month. The seedling height of 1 years old can reach 50 centimeters. If the seedlings are grown, they need to be planted in bed for 2 to 4 years.
2. Cutting seedlings can be cut in November and buried in the branches growing in spring. The cuttings are taken out in February and March of the following year. The cuttings are 0.3 cm to 0.4 cm in diameter and about 1518 cm in length per spike. The upper end is flat, the lower end is oblique, and the upper leaves are 12 pieces. The cuttings are inserted into the soil 2/3 plants are 10 cm apart, and rooted about 2 months after the cuttings. M.
Ligustrum lucidum is a common greening tree species in the Yangtze River valley, which has beautiful branches and leaves, evergreen all the year round, full of trees and white flowers in summer and adapts to the urban climate. It has strong resistance to various toxic gases and can be used as an anti pollution tree species in industrial and mining areas.
