丁香栽培技术Ding Xiang Ding Xiang spent a short, also known as purple Ding Xiang, ragged flowers, osmanthus flowers for families is a deciduous shrub or small tree. Plants with high 4~5m, the bark dark gray or gray-brown, a fissure, branches glabrous. Leaves ovate or reniform, apex acute, leaf base cordate, margin entire, leathery. Early spring flowers blossom, single or double, opened in the year branchlets, terminal or axillary, blossom end four crack, cylindrical, show panicle, flap soft purple color, fragrance Xiren, as Chinas famous garden flowers. 一、地块选择 A, site selection 丁香性喜阳光,忌积水,耐寒耐旱,一般不需多浇水。要求肥沃、排水良好的砂壤土,切忌栽于低洼阴湿处。如果栽在荫蔽环境中,则枝条细长较弱,花少且花序短小而松散。若种植在瘠薄的土地上,虽然也能生长,但花少,且长势瘦弱。因此,宜栽在向阳、肥沃、土层深厚的地方。 Clove like sunlight, avoid seeper, cold and drought resistance, generally do not need watering. Requirements of sandy loam soil fertile, well-drained, avoid by all means is planted in the low-lying damp. If planted in shade environment is weak, slim branches, flowers and inflorescences short and loose. If planted in poor soil, although also can grow, but spend less, and growing thin. Therefore, should be planted in sunny, fertile, deep soil. 二、苗木繁殖 Two, seedling breeding 1.种子繁殖,9~10月份,蒴果由绿色变为黄褐色,为种子成熟标志,应立即连同果枝剪下,以防种子散失。从小枝上采集果穗后及时放入通风干燥的室内阴干,不宜曝晒,以免种子强度失水而丧失生命力。在室内堆放厚度4~5cm,并经常翻动使其慢慢阴干,待有2/3蒴果开裂时,即可用柳条或其他木棒抽打脱粒,除去毗籽即得净籽。用清水浸泡种子,每5d换1次水,1个月后捞出用0.03%的高锰酸钾消毒2h,然后进行催芽(可常温也可加温),但要经常翻动。选择土质疏松肥沃的砂质土壤、排水良好、较干燥的地块,做成长10m、宽1.5m、高15~20cm的高床,底肥施碳铵150~225kg/hm2、腐熟有机肥30~45t/hm2,并用硫酸亚铁150kg/hm2或退菌特150~225 kg/hm2进行土壤消毒。秋季播种,秋播种子不必处理,采种后即在10月下旬播种,播幅宽8cm,行距宽20cm,沟深2~3cm,覆土厚度2.0~2.5cm,播后秋灌,以利保墒。翌年春发芽早,出苗也整齐。春季播种,处理过的种子经过催芽有30%种子裂嘴露白,4月下旬开始播种,技术同秋播。试验表明,春播比秋播效果好,虽然出苗迟,但出苗整齐,出苗率较高,而且生长略高。 1 seed breeding, 9~10 month, capsule change from green to brown, as seed maturity, should immediately with the branch cut, to avoid seed loss. Collection ear from branchlets timely in ventilated and dry room to dry, unfavorable insolate, lest seed strength loss and loss of vitality. Stacked 4~5cm thickness
