龙眼采用压条繁殖,能有效地提高成活率,方法简便,生长快,结果早。不少果农乐于使用。据漳浦县绥安镇果农经验,假植48000多株,平均成活率73.6％,最高达98％,其假植经验总结如下。1.压条落苗时间 落苗最佳时间视高压部根系萌生情况而定,以第一次根成熟(根色变黄),第二次根萌动为最好。过早,不定根脆弱易断,假植不易成活。太迟则由于根系生长受到高压部土球的限制而损伤了根系,影响成活率。如1989年9月所定植的高压苗中,其中有1000多株落苗时第三次根已成熟老化,结果假植后根系生长缓慢,甚至大量坏死,最后成活率只有30％多。其次,要注意落苗时的天气情况,锯苗时间以天晴、高压部土球较干燥为佳,若雨天土球太湿易变形破坏,加上运输震动,势必造 Longan battens multiply, can effectively improve the survival rate, the method is simple, fast growth, the result is early. Many farmers are happy to use. According to Zhangpu County Sui An fruit farmers experience, more than 48,000 plants planted, the average survival rate of 73.6%, up to 98%, the experience of their fake planting are summarized below. 1. Article time to fall seedling seedlings the best time depending on the Ministry of root initiation of high pressure Department may be the first root mature (root yellowing), the second root germination is the best. Premature, adventitious fragile fragile, implants difficult to survive. Too late, due to the growth of the root system by the Ministry of high pressure soil ball damage the root system, affecting the survival rate. As in September 1989 planted high-pressure seedlings, of which more than 1,000 strains of seedlings when the third root has matured aging, resulting in post-implants root growth slow, or even a large number of necrosis, the final survival rate of only 30%. Second, we should pay attention to the weather when the drop seedlings, sawing seedlings sunny days, high pressure Department of soil is better than the dry earth, if the rain is too damp earth deformation and damage, coupled with transport shocks, is bound to build
