| 摘 要： | 目的 探讨有机肥替代化肥在茄Solanum melongena生产中的作用。 方法 以单施化肥为对照(ck)，设置有机肥替代基肥中50%化肥氮(T1)和有机肥替代基肥中100%化肥氮(T2)2个处理，测定分析不同处理对露地茄产量、品质及土壤肥力的影响。 结果 相比ck，处理组土壤pH显著升高(P＜0.05)，土壤速效钾、有机质、微生物碳氮质量分数均显著增加(P＜0.05)；单果质量和单株结果数均显著提高(P＜0.05)，产量增加了13.8%~22.3%，其中T1产量最大，为70 099.5 kg·hm?2；处理组茄果皮花青素质量分数显著增加(P＜0.05)，茄外表皮紫红颜色更深；果实中镁和硫质量分数显著增加(P＜0.05)，可溶性糖、可溶性蛋白质和维生素C质量分数和氨基酸质量摩尔浓度均有不同程度提高，其中T1综合效果更优。 结论 选择有机肥替代基肥中50%的化肥可以有效地提高露地茄产量，改良品质，并改善土壤肥力。表9参40

| Abstract: | Objective This study aims to explore the effects of partial replacement of chemical fertilizer with organic fertilizer in the production of Solanum melongena. Method Taking chemical fertilizer as control (ck), 50% substitution of base nitrogen fertilizer with organic fertilizer (T1) and 100% substitution of base nitrogen fertilizer with organic fertilizer (T2) were set up as two treatments. The effects of different treatments on S.melongena yield, quality and soil fertility were studied in open field. Result Compared with ck, soil pH, soil available potassium, organic matter, microbial biomass carbon and nitrogen content increased significantly in both treatments (P＜0.05). The fruit weight and fruit number per plant increased significantly (P＜0.05), which led to the increase in yield by 13.8%?22.3%, and the yield of T1 was highest, which was 70099.5 kg·hm?2. The anthocyanin mass fraction of S.melongena pericarp increased significantly in both treatments(P＜0.05), and thus deepened the fruit color. The mass fraction of magnesium and sulfur in fruits increased significantly (P＜0.05), and that of soluble sugars, soluble protein and vitamin C and the molar concentration of amino acid increased in varying degrees, and the comprehensive effect of T1 was better. Conclusion Replacing 50% of the base fertilizer with organic fertilizer can effectively improve S. melongena yield, quality and soil fertility. Ch, 9 tab. 40 ref.] |
