【摘要】 【目的】分析甘蔗滤泥生物有机肥对茄子的施用效果,为其在蔬菜生产上的推广应用提供参考依据。【方法】以茄子为试验材料,设不施肥(对照,CK)、施复合肥、施75%复合肥+25%甘蔗滤泥生物有机肥、施50%复合肥+50%甘蔗滤泥生物有机肥和施25%复合肥+75%甘蔗滤泥生物有机肥共5个处理(分别为处理I～处理Ⅴ),分3批次取样测定分析不同处理茄子的农艺性状、养分吸收量、品质、产量和经济效益等指标。【结果】处理Ⅱ～处理Ⅴ和CK对第1、2批次取样茄子的株高、茎粗、冠幅横径、果实长度和粗度及单果重均无显著影响(P>0.05,下同);第3批次取样处理Ⅳ的株高、茎粗、冠幅横径及每小区总果数均明显优于其他处理。综合各农艺性状指标可知,处理Ⅳ的施肥配比(50%复合肥+50%甘蔗滤泥生物有机肥)是茄子施用甘蔗滤泥生物有机肥的最佳模式。除维生素C(Vc)总量外,处理Ⅳ茄子果实的其他养分吸收量及品质指标均最佳,处理V茄子果实的养分吸收量及品质在所有施肥处理中均最差。处理Ⅳ茄子的产量、经济效益和纯收入均最高,其中3批次取样的总纯收入(338323.3元/ha)分别比CK及处理Ⅱ、Ⅲ和Ⅴ高14.06%、0.84%、6.75%和21.92%。【结论】施用50%复合肥+50%甘蔗滤泥生物有机肥的茄子农艺性状、产量、经济效益及纯收入均较佳,该施肥配比可在茄子生产上推广应用。更多还原

【Abstract】 【Objective】Effects of sugarcane filter mud bio-organic manure on eggplant were studied to provide theoretical basis for the promotion of its application in vegetable production.【Method】Five different fertilization proportions including no fertilizer(control,CK,also set asⅠ),compound fertilizer(II),75% compound fertilizer+25% sugarcane filter mud bio-organic manure(III),50% compound fertilizer+50% sugarcane filter mud bio-organic manure(IV)and 25% compound fertilizer+75% sugarcane filter mud bio-organic manure(V)were applied to eggplant. The agronomic characters,nutrient absorption,quality and yield of eggplant under different fertilization treatments were determined from three samplings.【Result】The results showed that treatments Ⅱ-Ⅴ and CK had no significant effects on plant height,stem diameter,transverse crown diameter,length and diameter of eggplant in the first and second samplings(P>0.05,the same below).The plant height,crown diameter,transverse crown diameter and eggplant number per plot in Ⅳ in the third sampling were be-tter than other treatments. The agronomic traits analysis indicated that 50% sugarcane filter mud bio-organic manure(IV)was the optimal sugarcane filter mud bio-organic manure fertilization for eggplant. Except the vitamin C(Vc)content,the results of other nutrients absorption and quality indexes in IV were the best. Nutrients absorption and quality indexes in V were the worst. Yield,economic benefit and net income in Ⅳ treatment were the best. The total net income(338323.3 yuan/ha)of the three samplings were 14.06%,0.84%,6.75% and 21.92% higher than CK Ⅱ,Ⅲ and Ⅴ respectively.【Conclusion】Agronomic traits,yield,economic benefits and net income under 50% compound fertilizer+50%sugarcane filter mud bio-organic manure perform well,therefore this proportion can be promoted in eggplant production.更多还原
