不同施肥模式对油茶春梢生长和叶片酶活性的影响研究

Effects of different fertilization modes on growth and leaves enzyme activityof C.oleifera

为了科学管理油茶林地施肥,通过设置6个施肥模式,探究不同施肥模式对油茶春梢生长、叶片生长、春梢叶片养分累积、以及叶片酶活性产生的影响。结果表明:不同施肥模式对油茶春梢长度、直径、数量、生物量、叶片叶绿度值、春梢叶片数、春梢叶片养分含量和叶片酶活性均产生了显著影响,春梢长度、直径、数量、生物量与春梢叶片全氮、全磷及全钾养分含量间存在极显著正相关,其他指标间均存在极显著正相关,表明不同施肥模式与油茶春梢生长关系密切。不同施肥模式对油茶春梢生长、叶片生长的效果依次是M_0<M_2<M_3<M_1<M_5<M_4,模式4最能促进油茶春梢生长及春梢叶片生长;对油茶春梢梢数和叶片酶活性的效果依次是M_0<M_1<M_2<M_3<M_4<M_5,模式5能显著促进油茶春梢梢数增加及叶片酶活性的提高;对于油茶春梢叶片养分的效果依次是M_0<M_1<M_3<M_2<M_4<M_5,模式5对油茶春梢叶片养分的累积起着显著的作用;故在油茶林生产上推荐采用施肥模式M_5。

Differential woodland fertilization for scientific management, by setting the six fertilizing mode, explore the different fertilization pattern of oil-tea tip growth, leaf spring, spring pin leaf nutrient accumulation, as well as the impact of blade enzyme activity. Results showed that different fertilization pattern of oil-tea spring tip length, diameter, quantity, biomass, leaf spring of leaf number, leaf degree value, spring tip tip leaf nutrient content and leaf enzymes are produced significant influence, in the spring pin length, diameter, number, biomass and spring shoots leaf total nitrogen, total phosphorus and total potassium nutrient content is very significant positive correlation between, there were very significant positive correlation between other indicators, showed that different fertilization model and differential spring shoots grow dose.Different fertilization pattern on the effects of differential tip growth, leaf spring was followed by M0 〈 M2 〈 M3 〈 M1 〈 M5 〈 M4, pattern 4 most can promote the growth of camellia spring blade tip growth and spring tip; Of camellia becomes number and leaf spring the effect of the enzyme activity was followed by M0 〈 M1 〈 M2 〈 M3 〈 M4 〈 M5, mode 5 can significantly promote the oil-tea spring becomes by the increase in the number and leaf enzyme activity increase;For spring pin leaf nutrient of the effect was followed by Mo 〈 M3 〈 M1 〈 M2 〈 M4 〈 M5, mode 5 leaf spring of oil-tea of nutrient accumulation plays a significant role; So in the production of camellia Lin fertilization mode is recommended for the MS.
