以4种新型肥料(瑞利源(RLY)、汇源(HY)、中农1(ZN1)、中农2(ZN2))为试材,常规肥料为对照(CK),基于青海省海西州诺木洪和乌兰地区枸杞的施肥试验,研究了不同新型肥料对枸杞根际土壤总碳、全氮以及枸杞产量、品质的影响。结果表明:1)诺木洪试验地,RLY、ZN2处理土壤总碳含量比CK分别提高了4.49%和3.55%;4种处理下土壤全氮含量均小于CK。乌兰试验地,RLY、ZN1、ZN2处理的土壤总碳含量比CK分别提高了2.75%、2.33%和1.71%;土壤全氮含量均小于CK。2)诺木洪各施肥处理样地与CK相比,枸杞产量增幅分别为21.8%(RLY)、23.9%(HY)、12.7%(ZN)、25.4%(ZN2);乌兰各施肥处理样地与CK相比,枸杞产量增幅分别为12.7%(RLY)、9.9%(HY)、1.1%(ZN)、21.1%(ZN2);在诺木洪和乌兰样地,ZN2施肥处理枸杞产量增幅最高。3)诺木洪试验地新型肥料施肥处理未能显著增加枸杞多糖含量,乌兰试验地HY、ZN1、ZN2处理下枸杞多糖含量显著高于CK。
Four kinds of new fertilizers (RLY, HY, ZN1 and ZN2) were used as experimental materials, conventional fertilizers were used as control (CK), and based on Norwood Hong and Wulan wolfberry fertilization test to study the different new fertilizers on the wolfberry rhizosphere soil total carbon, total nitrogen and wolfberry yield and quality. The results showed as follows: 1) In Noiruhong experimental area, total carbon content of soil in treatments RLY and ZN2 increased by 4.49% and 3.55% compared with CK, respectively; soil total nitrogen content was less than CK under four treatments. In Wulan experiment, the contents of soil total carbon in treatments RLY, ZN1 and ZN2 increased by 2.75%, 2.33% and 1.71%, respectively, compared with CK. Soil total nitrogen content was less than CK. (2) Compared with CK, no significant difference was found in the fertilization treatments of Nomadsong and CK (21.8%, 23.9%, ZN) and 25.4% (ZN2) The yield of Chinese wolfberry was 12.7% (RLY), 9.9% (HY), 1.1% (ZN) and 21.1% (ZN2) respectively when compared with CK. In the Nongmuhong and Wulan plots, The highest increase. 3) The fertilization of new fertilizers in Nuomuhong could not significantly increase the content of Lycium barbarum polysaccharides. The contents of Lycium barbarum polysaccharides in HY, ZN1 and ZN2 treatments were significantly higher than those in CK.
