湖北咸宁市是全国桂花重点产区之一,对桂花苗木繁殖有着丰富的经验。全市每年繁殖桂花苗100多万株,其中短穗扦插繁殖占90%以上,短穗扦插繁殖具有成本低,速度快、成活率高、经济收入大的优点,一般头年春、夏扦插,次年春季移栽培育,第三年出圃,苗高可达一米以上,亩平收入在2.5—3万元。其方法是: 1、扦插时期:桂花从三月至九月均可扦插,全年分三次进行,第一次“春插”,清明至谷雨,选择桂花隔年秋梢扦插;第二次“夏插”,小署至大署,选择桂花当年生长幼梢扦插;第三次“秋插”,立秋至处署,选择当年生长较成熟新梢扦插。 Xianning City, Hubei Province, is one of the key producing areas of osmanthus, osmanthus seedlings have a wealth of experience breeding. The annual breeding sweet-scented osmanthus seedlings in the city more than 1 million, of which short-cuttage propagation accounted for more than 90%, short ear cutting propagation with low cost, high speed, high survival rate, the advantages of large economic income, usually the first spring and summer cutting, the following year Spring transplanting cultivation, the third year of nursery, seedlings up to one meter above, mu flat income in the 2.5-3 million. The method is: 1, cutting period: Osmanthus can be cuttings from March to September, the year is divided into three times, the first “spring inserted”, Qingming to Guyu, choose sweet-scented osmanthus autumn shoots of the next year; the second “summer Insert ”, the agency to the Department, the choice of osmanthus growth of young shoots cuttings; the third“ fall insert ”, set the beginning of autumn office, select the growth of more mature shoots cutting.
