摘要
为研究化肥减量配施有机肥对甜瓜生产的影响,实现化肥减量施用与节本增效,本研究设置了常规施肥(CK)、优化施肥(T1)、有机肥替代 10%化肥(T2)、有机肥替代 20%化肥(T3)共 4 个处理,按不同比例降低化肥用量并配施有机肥,测定不同处理的植株茎粗、根干/鲜质量、蔓干/鲜质量、可溶性总糖含量等指标,分析施肥方式对甜瓜品质和产量的影响.结果表明,适当降低化肥用量、配施有机肥能够促进植株生长,提升甜瓜产量,改善甜瓜品质,提高产品效益.与常规施肥相比,T2 处理在干物质量、维生素C含量、可溶性总糖含量、产量方面分别增加 1.25%、16.82%、41.28%、10.86%,增产提质效果最为显著.综上,减施 10%化肥并采用有机肥进行替代的施肥方案,可以提高甜瓜产量,改善甜瓜品质,建议推广,以提升经济效益和生态效益.
Abstract
To study the impact of reducing chemical fertilizers and applying organic fertilizers on the production of sweet muskmelon,and to achieve cost saving and efficiency improvement,this study set up four treatments:conventional fertilization(CK),optimized fertilization(T1),organic fertilizer substitution and reduction of 10%fertilizer application(T2),and organic fertilizer substitution and reduction of 20%fertilizer application(T3).The fertilizer application was reduced in different proportions and combined with organic fertilizer.By measuring the indicators of plant stem diameter,root dry and fresh mass,vine dry and fresh mass,soluble total sugar in different treatments,the effects of fertilization methods on quality and yield were analyzed.The results showed that reducing the amount of chemical fertilizers and applying organic fertilizers appropriately promoted plant growth,increased melon yield,improve melon quality,and enhanced product efficiency.Compared with conventional fertilization,T2 treatment increased dry matter mass,vitamin C content,soluble sugar content,and yield by 1.25%,16.82%,41.28%,and 10.86%,respectively,with the most significant effect of increasing yield and improving quality.In summary,reducing 10%chemical fertilizers and applying organic fertilizers could increase the yield and improve the quality of sweet melons.It was recommended promoting the reduction of chemical fertilizers and the application of organic fertilizers,to improve economic and ecological benefits.
