摘要：为探究不同改良施肥措施对3个不同品系桉树早期生长的影响,分析在同等低立地条件下桉树全营养基肥(S1)、有机肥+桉树全营养基肥(S2)、生物炭+生石灰+桉树全营养基肥(S3)、常规化肥(CK)对L11、L39、新桉8号3个品系桉树的早期生长的影响。结果表明:L11品系对S1响应最佳,胸径较CK高出9.30%,且蓄积量在4种施肥处理中最高,蓄积量达75.30 m3·hm?2,但L11在S1施肥处理下的树高生长表现最低;L39品系在S3处理下的综合优势明显,其树高、单株材积、保存率、蓄积量均优于其他处理,胸径的生长表现也较为突出,其中蓄积量较上一年增长50.03 m3·hm?2;新桉8号在CK处理下的综合生长表现最为突出,蓄积量达53.98 m3·hm?2,在S3处理下的生长表现最差,树高、胸径、单株材积以及蓄积量均低于CK。综合来看,不同改良施肥措施对不同品系的桉树早期生长有着不同程度的影响。在实际的桉树种植中,应根据具体的品系特点来选择合适的施肥措施。对于L11品系,可优先考虑使用桉树全营养基肥;对于L39品系,生物炭+生石灰+桉树全营养基肥能较好地促进其生长;而常规化肥则更符合新桉8号早期生长的营养需求。
To explore the effects of different improved fertilization measures on the early growth of three eucalypt clones under the same low site conditions,this study analyzed the impacts of four fertilization treatments,including eucalypt full-nutrient base fertilizer(S1),organic fertilizer+eucalypt full-nutrient base fertilizer(S2),biochar+quicklime+eucalypt full-nutrient base fertilizer(S3),and conventional chemical fertilizers(CK),on the early growth of eucalypt clones L11,L39,and Xin’an No.8.The results showed that clone L11 had the best response to S1.Its diameter at breast height(DBH)was 9.30%higher than that of CK,and its volume was the highest among the four fertilization treatments,reaching 75.30 m3·hm?2.However,the height growth of L11 under S1 treatment was the lowest.Clone L39 showed obvious comprehensive advantages under S3 treatment.Its height,individual tree volume,survival rate,and stand volume were all better than those under other fertilization treatments,and the growth performance of DBH was also prominent.Among them,the stand volume increased by 50.03 m3·hm?2 compared with the previous year.Clone Xin’an No.8 had the most prominent comprehensive growth performance under CK treatment,with a stand volume of 53.98 m3·hm?2,while its growth performance under S3 treatment was the worst,with height,DBH,individual tree volume,and stand volume all lower than those of CK.In conclusion,different improved fertilization measures had different degrees of influence on the early growth of different eucalypt clones.In practical eucalypt planting,appropriate fertilization measures should be selected according to the specific characteristics of clones.For clone L11,eucalypt full-nutrient base fertilizer(S1)was preferred;for clone L39,the combination of biochar+quicklime+eucalypt full-nutrient base fertilizer(S3)could better promote its growth;while conventional chemical fertilizers(CK)better met the nutritional needs of Xin’an No.8 during its early growth stage.
