施肥对黎蒴栲幼苗叶绿素含量的影响
|
摘要
为了探讨苗期施肥对黎蒴栲叶片叶绿素含量的影响,采用均匀设计对黎蒴栲实生幼苗进行不同梯度的配比施肥试验。结果表明:施肥处理T_4(N 0.112 5 g/株、K_2O 0.050 0 g/株)、T_5(N 0.075 0 g/株、P_2O_5 0.350 0 g/株)均较有利于黎蒴栲幼苗的生长。施氮肥处理的黎蒴栲苗木叶片叶绿素a、叶绿素b、总叶绿素含量均高于未施氮肥处理(T_3,P_2O_5 0.175 0 g/株、K_2O 0.100 0 g/株)和对照的,施氮肥有利于黎蒴栲幼苗叶片叶绿素的积累。黎蒴栲叶片叶绿素含量在施肥前期,与氮肥施用量呈正相关;后期生长阶段,叶片叶绿素含量与其生长状况密切相关。可通过叶片叶绿素含量了解植物对氮肥的需求情况。
The uniform design was applied to test of different gradient ratio fertilizing of Castanopsis fissa seedlings,discussed effects of fertilization on leaf chlorophyll content of C.fissa seedlings.The results showed that:T_4 treatment fertilizer(N:0.112 5 g/plant,K_2O:0.050 0 g/plant) and T_5 fertilization treatment(N:0.075 0 g/plant,P_2O_5:0.350 0 g/plant)were best for C.fissa seedlings growth.Nitrogen treatment of C.fissa seedlings of chlorophyll a content,chlorophyll b content,and total chlorophyll content were higher than no nitrogen T_3(P_2O_5:0.175 0 g/plant,K_2O:0.050 0 g/plant)treatment and contrast,nitrogen was conducive to the accumulation of C.fissa seedlings leaf chlorophyll.In the fertilization treatment early growth stage,C.fissa seedlings leaf chlorophyll content had certain relationships with nitrogen application amoumt;in the late growth stage,C.fissa leaf chlorophyll content had certain relationships with its growth.The needs of nitrogen of plants were known through the chlorophyll content in leaves.
