摘要
为分析不同肥料处理下油茶林生长发育状况以及油茶产量的变化。在2020~2022年,于青田县某油茶生产基地开展了试验,设置3个处理,分别为对照组(不施肥)和试验Ⅰ组(施用复合肥)、试验Ⅱ组(施用复合肥+微生物有机菌肥),对比了三个处理油茶林生长发育状况、油茶产量。结果表明:试验Ⅱ组叶片、枝干、根系、全株生物量显著高于试验Ⅰ组(P<0.05),极显著高于对照组(P<0.01);试验Ⅱ组年平均树高、冠幅增长量显著高于试验Ⅰ组(P<0.05),极显著高于对照组(P<0.01);试验Ⅰ组和试验Ⅱ组单株平均产量无显著差异(P>0.05),但是均显著高于对照组(P<0.05);试验Ⅱ组鲜果含油率显著高于试验Ⅰ组和对照组(P<0.05),三组干出仁率、干出籽率、种仁含油率比较无显著差异(P>0.05)。指出了施用复合肥+微生物有机菌肥不仅对油茶林生长发育产生促进作用,还能有效提高油茶产量和鲜果含油率。
Objective To analyze the growth and development of Camellia oleifera forest and the change of Camellia oleifera yield under different fertilizer treatments.Methods The experiment started in 2020 and ended in 2022,and lasted for three years.The experiment was carried out in a Camellia oleifera production base in Qingtian county,and three treatments were set up,namely,control group(no fertilization),experiment groupⅠ(compound fertilizer application)and experiment groupⅡ(compound fertilizer+microbial organic bacterial fertilizer application).The growth and development status and Camellia oleifera yield of the three treatments were compared.Results The biomass of leaves,branches,roots and whole plant in the experimental groupⅡwas significantly higher than that in the experimental group I(P<0.05),and extremely significantly higher than that in the control group(P<0.01).The average annual growth of tree height and crown width in experimental groupⅱwas significantly higher than that in experimental groupⅠ(P<0.05),which was significantly higher than that in control group(P<0.01).There was no significant difference in the average yield per plant between the experimental group I and the experimental groupⅡ(P>0.05),but both were significantly higher than the control group(P<0.05).The oil content of fresh fruit in experimentⅱgroup was significantly higher than that in experimentⅠgroup and control group(P<0.05),but there was no significant difference in dry kernel rate,dry seed rate and seed kernel oil rate among the three groups(P>0.05).Conclusion On the whole,the application of compound fertilizer and microbial organic bacterial fertilizer not only promotes the growth and development of Camellia oleifera forest,but also effectively improves the yield and fresh fruit oil content.
