滴灌配方施肥对盛果期油茶春梢生长的影响

         

摘要

In order to provide some references for research,development and utilization of fertigation in practice prodution of Camellia oleifera at full bearing period,some liquid fertilizers with different formula were applied to C.oleifera forest at full bearing period by fertigation,and their effects on spring bearing shoots in C.oleifera were investigated.The results showed that formulary fertigation could obviously promote growth of spring shoots in C.oleifera,and effects of different fertigation treatments had significant differences.The fertigation formular with the best effect of promoting top shoots growth of bearing branches in C.oleifera was the original fluid formula 3 diluted to 5% (the mass ratio of N,P,K,B,Zn and Mg was 2 ∶ 2 ∶ 1 ∶ 0.02 ∶ 0.03 ∶ 0.01),and top shoot length,top shoot diameter,flower bud number,leaf area and leaf SPAD were increased by 32.38%,22.58%,17.95%,4.07% and 14.60%,respectively,compared with control.In addition,fertigation formular with the best effect of promoting lateral shoots growth of bearing branches in C.oleifera was the original fluid formula 2 diluted to 10% (the mass ratio of N,P,K,B,Zn and Mg was 5 ∶ 3 ∶ 2 ∶ 0.02 ∶ 0.03 ∶ 0.01),and lateral shoot length,lateral shoot diameter,flower bud number,leaf area and leaf SPAD were increased by 58.40%,57.34%,3.52%,6.05% and 7.46%,respective,compared with control.%为给盛果期油茶生产实际中滴灌施肥的研制及开发利用提供借鉴,在盛果期油茶林滴灌设施中施用不同配方的液态肥料,并调查其对油茶结果枝春梢的影响.结果表明:配方滴灌施肥可以明显促进油茶春梢的生长,且在不同施肥处理下的效果差异显著,其中对油茶结果枝项梢生长促进效果最好的滴灌施肥配方为原液3 (N、P、K、B、Zn、Mg质量比为2∶2∶1∶0.02∶0.03∶0.01)稀释5%,与对照相比,可使顶梢的抽梢生长量增长32.38%,抽梢粗度提高22.58%,花芽数增多17.95%,叶面积增大4.07%,叶片叶绿度提高14.60%;而对油茶结果枝侧梢生长促进效果最好的滴灌施肥配方为原液2(N、P、K、B、Zn、Mg质量比为5∶3∶2∶0.02∶0.03∶0.01)稀释10%;相比对照可使侧梢的抽梢长增长58.40%,抽梢粗度提高57.34%,花芽数增多3.52%,叶面积增加6.05%,叶片叶绿度提高7.46%.
