不同施肥模式对朱顶红幼苗生长指标的影响

摘要

以进口朱顶红栽培品种双龙为试验材料,比较花多多水溶性肥料(20-20-20)和芭田高塔复合肥(15-15-15)的不同施肥水平和施肥周期对其盆栽苗生长的影响.结果表明,在试验浓度范围内,合理施肥能显著增加双龙幼苗的叶片数、最长叶长和球直径,有利于诱导根系的发生和生长,对双龙叶片叶绿素含量积累具有积极作用;每14d喷施1 mg/L芭田复合肥能较大程度节约投入成本;每14d喷施1.5 mg/L花多多水溶肥能达到最佳施肥效果;进行朱顶红大田生产建议选择每14d施用1 mg/L芭田复合肥;进行盆栽生产及对朱顶红生长表现要求较高时,建议选择每14d施用1.5 mg/L花多多水溶肥.%Taking Hippeastrum hybridum'Double Dragon'as material,this paper studied the effect of different fertilization levels and fertilization cycles on seedling growth of Hippeastrum hybridum'Double Dragon'.The results showed that in the range of experimental concentrations,rational fertilization could significantly increase the number of leaves,the longest leaf length and the bulb diameter of 'Double Dragon',which was beneficial to the ocurrence and growth of root system,and fertilization had a positive effect on the accumulation of chlorophyll content in the leaves of'Double Dragon'.In order to save a considerable degree of input costs,the paper chose to spray 1 mg/L compound fertilizer (15-15-15) per 14 days,and if it needed to get the best fertilization effect,it could choose to spray 1.5 mg/L of water-soluble fertilizer(20-20-20) per 14 days.When carrying out the field production of Hippeastrum hybridum'Double Dragon',it was recommended to spray 1 mg/L compound fertilizer every 14 d.And when need to achieve higher growth performance requirements and pot plants,it was recommended to spray 1.5 mg/L of water-soluble fertilizer every 14 d.
