腐殖酸水溶肥对芦笋生长·产量及营养成分的影响

Effects of Humic Acid Water-soluble Fertilizer on Growth,Yield and Nutrient Content of Asparagus

通过小区试验,设置喷施腐殖酸水溶肥(TF)、清水(TW)和无喷施的常规施肥(CK)3个处理,研究喷施腐殖酸水溶肥对芦笋生长、产量、营养成分和经济效益的影响。结果表明,TF对芦笋嫩茎生物学性状(单株茎数、长度、茎粗、质量)的影响显著优于TW和CK。TF比TW和CK显著增加了芦笋产量(P<0.05),增幅分别为9.5%和13.1%。TF比CK显著增加了芦笋嫩茎的总黄酮、皂苷和多糖含量(P<0.05),增幅分别为6.8%、2.9%和15.1%。但3个处理芦笋嫩茎的氨基酸含量差异不显著(P>0.05)。TF比TW和CK增加了芦笋的净经济效益,增幅分别为9966和12552元/hm^(2)。因此,芦笋喷施腐殖酸水溶肥值得进一步推广应用。

Three treatments of sprayed humic acid water-soluble fertilizer(TF),fresh water(TW)and conventional fertilization without spraying(CK)were set up in a plot experiment to study the effects of spraying humic acid water-soluble fertilizer on the growth,yield,nutrient contents and economic benefits of asparagus.The results showed that TF was significantly superior to TW and CK in terms of the biological characteristics of asparagus stems(number of stems per plant,length,stem thickness and mass).TF increased significantly asparagus yield by 9.5%and 13.1%compared with TW and CK(P<0.05),respectively.TF significantly(P<0.05)increased the total flavonoids,saponins and polysaccharides contents of asparagus shoots by 6.8%,2.9%and 15.1%,respectively,compared with CK.However,the amino acid content of asparagus shoots from the three treatments did not differ significantly(P>0.05).TF increased the net economic benefits of asparagus by 9966 and 12552 yuan/hm^(2) compared with TW and CK,respectively.Therefore,spraying humic acid water-soluble fertilizer on asparagus is worth further popularization and application.
