Effects of extract of Irpex lacteus combined with amino acid water-soluble fertilizer on yield and quality of lettuce
摘要
Abstract
Endophytic extract(BABC),derived from Irpex lacteus,has significant effects on growth promotion,yield increase and disease resistance.The combination of BABC and amino acid water-soluble fertilizer can synergize the advantages of them and increase the efficacy of the product.In order to explore the effects of different application methods and concentrations of BABC and amino acid water-soluble fertilizer on the yield and quality of lettuce,indoor pot experiment and field experiment were conducted to provide scientific basis for the application and promotion of BABC in vegetable production.The results showed that the single application and the combination of BABC and amino acid water-soluble fertilizer promoted the growth and development of lettuce in different degrees,and improved the yield and quality of lettuce.The principal component analysis of each index in indoor pot experiment showed that the comprehensive index of T-375(spraying treatment)and T-7500(irrigation treatment)was the best.The fresh weight of T-375 lettuce leaf was 31.69%higher than that of CK1,and that of T-7500 was 29.23%higher than that of CK2.The spraying treatment method was selected for further verification in the field experiment.The results showed that both single application and combination of BABC and amino acid water-soluble fertilizer increased the yield,improved the quality and improved the safety of lettuce.Among them,T-375 and T-750 treatments had a significant synergic effect on lettuce production compared with single application of BABC and amino acid water-soluble fertilizer,and the best effect on lettuce production was increased by 46.68%and 47.34%,compared with CK,respectively.Compared with CK,the contents of chlorophyll,vitamin C,soluble sugar,soluble protein of lettuce in T-375 and T-750 treatment were increased by 27.95%,66.87%,172.58%,82.76%and 37.46%,62.39%,135.48%,55.17%,respectively,while the content of nitrate was decreased by 52.52%and 62.70%,respectively.Therefore,the combination of BABC and amino acid water-soluble fertilizer had a synergistic effect,and leaf spraying and irrigation could promote the growth of lettuce,significantly improve the yield,nutritional quality and safety of lettuce.Among them,375 g/hm2 BABC and water-soluble amino acid fertilizer compound(7.5 g/hm2 BABC+367.5 g/hm2 amino acid water-soluble fertilizer)spray treatment had outstanding effect on the increase and quality of lettuce,and the amount was less and the cost was low,which was the optimal application method and application amount.关键词
