摘要
为考察含黄腐酸钾复合肥(14-12-14)在三樱椒生产中的应用效果,以普通复合肥(15-15-15)为对照,在5个试验点开展了田间试验。结果表明,在总养分减施28.9%的条件下,施用含黄腐酸钾复合肥对三樱椒的叶片叶绿素相对含量(SPAD值)、分枝数无显著影响,对增大植株株高有显著作用,对增加开花数量、增强抗病性及提高产量有一定促进作用。施用含黄腐酸钾复合肥能促进三樱椒生长,提高产量。
Taking regular compound fertilizer(15-15-15) as the control, field experiments are carried out in five test sites to investigate the application effects of compound fertilizer containing fulvic acid potassium(14-12-14) in the production of Capsicum annuum L.var.conoides(Mill.) Irish. The results show that under the condition of reducing the total nutrients by 28.9%, the application of compound fertilizer containing fulvic acid potassium has no significant effect on the relative chlorophyll content(SPAD value) of leaves and the number of branches of Capsicum annuum L.var.conoides(Mill.) Irish, but has a significant effect on increasing the plant height, increasing the number of flowers, enhancing disease resistance and increasing the yield. Applying compound fertilizer containing fulvic acid potassium can promote the growth of Capsicum annuum L.var.conoides(Mill.) Irish and increase the yield.
