摘要:

为比较和评估5种土壤改良剂对广西柳州融安县中性翻耕土壤上种植的融安脆蜜金柑的效果,使用2种新型改良剂[氨基酸改性生物质灰(MBA)、氨基酸改性木屑(MSD)]、3种商售土壤改良剂[白云石(DOL)、生物炭(BC)、腐殖酸钾(HAP)(用作对照)],通过测定土壤主要有效养分含量、植株生长过程中叶片的光合特性及果实品质指标,筛选最优土壤改良剂。结果表明,5种土壤改良剂组成的各处理中,“基肥+氨基酸改性生物质灰”(CK+MBA)处理表现出最优的综合效果,土壤碱解氮、有效磷、有机质和有效锰含量最高,同时使植株叶片的净光合速率和气孔导度达到最大值。此外,该处理下果实的可溶性固形物含量、果形指数和固酸比也显著高于其他处理。“基肥+白云石”(CK+DOL)和“基肥+腐殖酸钾”(CK+HAP)处理效果次之,但各具特色;CK+DOL处理能有效增加土壤有效态养分含量,但会增加土壤有效铅、有效钠含量;CK+HAP处理可显著提高果实的单果重、出汁率和维生素C含量。综上所述,氨基酸改性生物质灰在5种改良剂中表现最佳,白云石和腐殖酸钾次之,建议在中性土壤种植脆蜜金柑时优先应用氨基酸改性生物质灰。

Abstract:

The purpose of this research is to compare and evaluate the effects of five kinds of soil conditioners used in the cultivation of crispy honey kumquats on neutrally tilled soil of Rong’an County, Liuzhou City, Guangxi Province. In this study, two kinds of new amendments, amino acid-modified biomass ash (MBA) and amino acid-modified wood chips (MSD), and three kinds of commercially available soil amendments, dolomite (DOL), biochar (BC) and potassium humate (HAP) (used as the controls) were used for planting Cuimi kumquat. Optimal soil conditioners were selected from three aspects: the contents of soil available nutrients, the photosynthetic characteristics of leaves during plant growth, and the quality indexes of harvested kumquat fruits. The results showed that among the treatments originated from 5 kinds of soil conditioners, the comprehensive effect of the ‘base fertilizer+ amino acid modified biomass ash’ (CK+MBA) treatment was the best. Under this treatment, the soil alkali hydrolyzable nitrogen, available phosphorus, organic matter and available manganese contents were significantly higher than those of other treatments, the net photosynthetic rate and stomatal conductance of plant leaves were the highest, and the soluble solids content, fruit shape index and solid-acid ratio of fruit were the highest. The second were ‘base fertilizer + dolomite’ (CK+DOL) and ‘base fertilizer + potassium humate’ (CK+HAP) treatments, each treatment had its own advantages and disadvantages, in which CK+DOL treatment had a good effect on the soil available nutrient contents, but would increase the soil available lead and available sodium contents, and CK+HAP treatment had the highest single fruit weight of kumquat fruit, the highest juice yield and vitamin C content. MBA had the best comprehensive effect among the five conditioners, followed by DOL and HAP, which could be preferentially promoted and applied in the production of Cuimi kumquat on neutral soil.
