不同配方肥料及用量对金桔产量和品质的影响

Effects of Different Formula Fertilizers and Amounts on Yield and Quality of Fortunella margarita(Lour.)Swingle

本研究以广西壮族自治区阳朔县的低产金桔果园为供试材料,设置了10种不同的施肥配比方案对金桔产量和品质(商品果率、固形物含量、可滴定酸含量)的影响,分别为:处理1-复合肥料1(250 g)+巨微生物钾肥(50 g)、处理2-复合肥料1(350 g)+巨微生物钾肥(50 g)、处理3-复合肥料1(250 g)+巨微生物钾肥(30 g)、处理4-复合肥料1(350 g)+巨微生物钾肥(30 g)、处理5-复合肥料2(250 g)+巨微生物钾肥(50 g)、处理6-复合肥料2(350 g)+巨微生物钾肥(50 g)、处理7-复合肥料2(250 g)+巨微生物钾肥(30 g)、处理8-复合肥料2(350 g)+巨微生物钾肥(30 g)、处理9-复合肥料1(350 g)+巨微生物钾肥(0 g)、处理10-对照。结果表明:(1)施肥处理1、5、7的商品果率、固形物和可滴定酸含量显著高于其他处理;(2)生物菌肥的添加,能激发肥效,增加金桔植株对复合肥料的吸收;(3)施肥处理1的综合提升效果最显著,增产增效效果最佳,更适宜在桂北低产低效金桔残次林、低产果园中进行推广。

Adopting fertilization schemes according to local conditions is the key to study and explore the transformation of Fortunella margarita(Lour.)Swingle residual forests and low-yield orchards,and to effectively improve the yield and fruit quality of F.margarita.In this study,the low-yield F.margarita orchard in Yangshuo County,Guangxi Zhuang Autonomous Region was used as the test material,and 10 different fertilization ratios were set up to affect the yield and quality of F.margarita(commodity fruit rate,solid content,titratable acid content).Treatment 1-compound fertilizer 1(250 g)+Giant microbial potassium fertilizer(50 g),treatment 2-compound fertilizer 1(350 g)+Giant microbial potassium fertilizer(50 g),treatment 3-compound fertilizer 1(250 g)+Giant microbial potassium fertilizer(30 g),treatment 4-compound fertilizer 1(350 g)+Giant microbial potassium fertilizer(30 g),treatment 5-compound fertilizer 2(250 g)+Giant microbial potassium fertilizer(50 g),treatment 6-compound fertilizer 2(350 g)+Giant microbial potassium fertilizer(50 g),treatment 7-compound fertilizer 2(250 g)+Giant microbial potassium fertilizer(30 g),treatment 8-compound fertilizer 2(350 g)+Giant microbial potassium fertilizer(30 g),treatment 9-compound fertilizer 1(350 g)+Giant microbial potassium fertilizer(0 g),treatment 10-control.The effects of different fertilizer ratios on the yield and quality of F.margarita(commercial fruit rate,solid content,titratable acid content)were studied.The results showed that:(1)Commercial fruit rate,solids and titratable acid content of treatments 1,5,and 7 were significantly higher than those of others;(2)The addition of microbial fertilizer can stimulate fertilizer efficiency and increase absorption of compound fertilizers;(3)Treatment 1 has the most significant comprehensive improvement effect and the best effect of increasing yield and efficiency.It is more suitable for promotion in low-yield and low-efficiency F.margarita secondary forests and low-yield orchards.
