Effects of plant-derived amino acid water-soluble fertilizer on fruit quality and nutritional growth of Myrica rubra
The study of the effect of plant-derived amino acid on the quality of bayberry(Myrica rubra)can provide a theoretical basis for the application of Liweishuangbao(L).Taking Dongkui as the research object,plant-derived amino acid water-soluble fertilizer(L)was selected as the experimental material,and animal-derived amino acid(Y)was used as the reference fertilizer,which were sprayed three times at two dilution concentrations of 1 000 and 500 times in the budding,young fruit,and hardening stages of bayberry,respectively.The results show that amino acid fertilizer can improve the yield,increase the contents of fruit total soluble solids(TSS)and sucrose,in which the increasing of L10(low concentration of L)and Y5(high concentration of Y)was obvious,and the sucrose increased by 29.2%and 31.2%,respectively.Amino acid fertilizer promoted the absorption of various nutrients by plants.The treatments of L increased the content of eight elements in leaves,including nitrogen,phosphorus,potassium,calcium,magnesium,manganese,zinc,and copper,as well as increasing the leaf surface area.Compared with the reference fertilizer,L performed more significantly at lower concentrations,indicating that it is more efficient.In conclusion,amino acid water-soluble fertilizer application on the leaf surface can increase the yield of bayberry,improve the quality,enhance the nutritional growth of crop,and increase the income.
