不同施肥模式对芒果产量、品质的影响

探讨不同施肥模式对芒果产量、品质的影响,为芒果园科学合理的施肥方式提供依据.以'台农'为研究对象,在海南芒果主产区的乐东县红泰农场芒果园进行大田试验,共设置7个处理:不施肥(CK)、化肥20 cm浅施(H2)、化肥40 cm深施(H4)、生物有机肥替代20％N 20 cm浅施(T2)、生物有机肥替代20％N 40 cm...

Effects of Different Fertilization Patterns on Yield and Quality of Mango

The effects of different fertilization patterns on mango yield and quality were explored.Taking‘Tainong’as the research material,a field experiment was carried out in the mango orchard oin Hongtai Farm in Ledong County,the main mango producing area in Hainan.Seven treatments including No Fertilization(CK),chemical fertilizer 20 cm shallow application(H2),chemical fertilizer 40 cm deep application(H4),biological organic fertilizer replacement 20%N 20 cm shallow application(T2),biological organic fertilizer replacement 20%N 40 cm deep application(T4),water and fertilizer integration 20 cm shallow application(SH2),water and fertilizer integration 40 cm deep application(SH4)were used.The yield and economic benefits of chemical fertilizer,organic substitution,and integrated water and fertilizer treatment were significantly higher than those of CK,of which the yield and economic benefits of SH4 treatment were 203.64% and 266.87% higher than that of CK,and the yield and economic benefits of T2,T4 and SH4 treatment were significantly higher than that of H2 treatment,of which the yield and economic benefits of SH4 treatment were 23.25% and 31.28% higher than that of H2 treatment.The fruit length,transverse diameter and fruit thickness of fertilizer treatment were significantly higher than those without fertilization,and the fruit type index of SH4 treatment was significantly higher than that of CK.The soluble solids,sugar-acid ratio and solid-acid ratio of fertilization treat762 ment were significantly higher than that of CK,the content of soluble solids in SH4 treatment increased by 14.45% compared with CK.The total acid content of CK treatment was significantly higher than that of fertilization treatment.The total acid content of H2 treatment was significantly higher than that of deep chemical fertilizer application,organic substitution,and water and fertilizer integration.Among them,the total acid content of SH4 treatment was 78.79% less than CK and 48.98% less than H2.Vc and soluble sugar were not significantly different among the treatments.According to the principal component evaluation of fruit yield and quality,the main component scores of each index of the fruit were in the order of:SH4>T4>SH2>T2>H4>H2>CK.Under the conditions of this experiment,deep application of 40 cm water and fertilizer is the best pattern to improve mango yield,quality and economic benefit.
