海藻套餐肥料对沾化冬枣产量和品质的影响

Effects of seaweed compost fertilizer on yield and quality of Zhanhua winte jujube

通过测定施肥前后冬枣(Ziziphus jujuba Mill. cv. dongzao)种植区域的土壤理化性质及枣树的根系参数、养分吸收量、果实产量和品质等指标,评价了海藻套餐肥料的肥效。结果发现,与未施肥对照相比,海藻套餐肥料能显著改善土壤肥力状况,提高土壤微生物生物量碳和氮(P<0.05)。与施用常规市售肥料处理相比,施用海藻套餐肥料后提高了枣树0~20 cm土层的根长密度、根系活力和枣果产量,并显著提高了枣果可溶性固形物、维生素C、总糖、可溶性蛋白质含量(P<0.05)。这表明海藻套餐肥料能通过改善土壤肥力、提高土壤微生物活性,增加枣树根系生长和养分吸收,从而提高枣果产量及品质。

The fertilizer efficiency of seaweed compost fertilizer was evaluated by measuring soil physical and chemical properties,root parameters,nutrient absorption,fruit yield and quality of winter jujube(Ziziphus jujuba Mill.cv.dongzao)before and after fertil⁃ization.The results showed that compared with no fertilization,seaweed compost fertilizer could significantly improve soil fertility and increase soil microbial biomass carbon and nitrogen(P<0.05).Compared with conventional fertilizer treatment,the application of sea⁃weed compost fertilizer increased the root length density of 0~20 cm soil layer,root activity and fruit yield of the jujube tree,and sig⁃nificantly increased the contents of soluble solids,vitamin C,total sugar and soluble protein of jujube fruit(P<0.05).It indicated that seaweed compost fertilizer could increase root growth and nutrient absorption of jujube trees by improving soil fertility and increasing soil microbial activity,and ultimately improve the yield and quality of jujube fruit.
