水溶肥添加微量元素和增效剂对朝天椒生长及产量的影响

摘要

A pot experiment was carried out to study the effects of water -soluble fertilizer with trace ele-ments ( B 0.05%, Fe 0.06%, Mn 0.02%, Cu 0.02%, Zn 0.05%, Mo 0.005%) and synergist on growth and yield of chili pepper .The results indicated that water -soluble fertilizer with trace elements ( WSF +TE) treatment and water -soluble fertilizer with trace elements and synergist (WSF +TE +SNG) treatment both could boost plant height and stem diameter , increase chlorophyll ( SPAD) content and improve photosyn-thetic capacity during early growth stage .The pepper yield of WSF+TE treatment and WSF+TE+SNG treat-ment increased by 35.98% and 11.03% respectively compared with water -soluble fertilizer ( WSF) treat-ment, while that of WSF +SNG treatment decreased by 23.78%.It indicated that water -soluble fertilizer with trace elements could promote growth and increase yield of chili pepper .Thus, trace elements could be used as adding material for further research and development of special water -soluble fertilizer for chili pep-per .%采用室内盆栽方法研究了冲施水溶肥条件下，添加微量元素（ B 0．05％，Fe 0．06％，Mn 0．02％， Cu 0．02％，Zn 0．05％，Mo 0．005％）、增效剂对朝天椒生长和产量的影响。结果表明，水溶肥＋微量元素（ WSF＋TE）处理、水溶肥＋微量元素＋增效剂（ WSF＋TE＋SNG）处理能提高朝天椒株高和茎粗，增加朝天椒生长前期叶片叶绿素（ SPAD ）含量，提高光合能力；朝天椒产量分别比只施水溶肥处理提高35．98％、11．03％，水溶肥＋增效剂（WSF ＋SNG）处理的产量降低23．78％。说明水溶肥添加微量元素能促进辣椒生长、提高辣椒产量，微量元素可以作为添加料用于进一步研发朝天椒专用水溶肥。
