对巨桉二代萌芽更新进行整地施肥试验研究,结果表明:整地即伐前全翻土10cm～15cm,对巨桉二代萌芽更新效果、萌芽林生长均没有影响。而施肥能明显促进萌芽林的生长,与一代新植林一样,合理施肥是提高二代萌芽林生长量和维护地力的关键技术措施,在萌芽条萌发稳定后,结合整理萌芽条、除草培土,每伐根施过磷酸钙250g+复合肥200g对促进根系发育、林分生长都是相当有利的,但合理的施肥量还有待进一步研究。
The second generation of Eucalyptus germination and regeneration of land fertilization experiment study showed that: preparation of land that is full of pre-cutting soil 10cm ~ 15cm, the second generation of Eucalyptus germination and regeneration of sprouting forest growth have no effect. Fertilization can obviously promote the growth of sprout forest. Like the new generation of plantation, the rational fertilization is the key technical measures to increase the growth of second-generation sprout forest and maintain the soil fertility. After the sprout germination is stable, combined with budding and weeding, Fluxed through calcium phosphate 250g + 200g compound fertilizer to promote root development, stand growth are quite favorable, but a reasonable amount of fertilizer remains to be further studied.
