已知白蚁丘土具有独特的物理化学和生化特性,使它们高度肥沃。考虑到它们丰富的营养成分,当前实验的目的是评估基于白蚁丘的盆栽介质的理化性质和酶活性,并评估其性能,以进一步探索花卉栽培。由地下白蚁的白蚁丘土(TS)组成的灌封介质,Odontotermesobesus与花园土壤(GS)以7种不同的组合制备,砂(S)和农家肥(FYM)和对照(无白蚁土堆),即,T1(TS,GS,S,FYM(v:v:v:v/1:2:1:1)),T2(TS,GS,S,FYM(v:v:v:v/2:1:1:1)),T3(TS,S,FYM(v:v:v/2:1:1)),T4(TS,GS,FYM(v:v:v/2:1:1)),T5(TS,GS,S(v:v:v/2:1:1)),T6(TS,S,FYM(v:v:v/3:1:1)),T7(TS,S,FYM(v:v:v/1:1:2))和控制(GS,S,FYM(v:v:v/2:1:1))。然后在实验室中分析样品。对物理化学和生物学参数的实验分析揭示了T7(TS,S,FYM(v:v:v/1:1:2))以pH(7.15)表示,有机碳(2.13%),有效氮(526.02kgha-1),有效磷(56.60千克ha-1),有效钾(708.19千克ha-1),脱氢酶活性(18.21μgTTFg-1土壤第1天),磷酸单酯酶(PME)活性(46.6854μg对硝基苯酚/gsoil/h)和脲酶活性(3.39μgNH4-Ng-1土壤h-1)。而T4(TS,GS,FYM(v:v:v/2:1:1))在PME活性方面的优势(50.54μg对硝基苯酚/gsoil/h),荧光素二乙酸酯(FDA)活性(11.01μg荧光素/gsoil/h)和土壤微生物生物量碳(SMBC)(262.25μg/g)。在实验室分析之后,选择了两种最佳的盆栽混合物(T7和T4),并通过种植测试作物来评估其性能,万寿菊cv。印加橙.考虑到生长参数,灌封介质:T7被发现在植物传播方面显着优越(39.64厘米),叶面积指数(4.07),鲜重(37.72克),产量(317.81克/株),和花的直径(9.38厘米)超过T4和对照。确定了收益:成本(B:C)比率,这意味着净收益与种植总成本的比率。在T7中作为盆栽植物饲养万寿菊花的B:C比为1.10,而T7的盆栽混合物的B:C比为2.52。这表明T7灌封介质对于商业目的也是经济上可行的选择。
Termite mound soils are known to possess unique physico-chemical and biochemical properties, making them highly fertile. Considering their rich nutrient content, the objective of the current experiment is to assess the physico-chemical properties and enzyme activities of termite mound based potting media and evaluate theirperformance for further exploration in floriculture. Potting media consisting of termite mound soil (TS) of a subterranean termite, Odontotermes obesus were prepared in 7 different combinations with garden soil (GS), sand (S) and farmyard manure (FYM) and a control (without termite mound soil), i.e., T1 (TS, GS, S, FYM (v:v:v:v /1:2:1:1)), T2 (TS, GS, S, FYM (v:v:v:v / 2:1:1:1)), T3 (TS, S, FYM (v:v:v / 2:1:1)), T4 (TS, GS, FYM (v:v:v / 2:1:1)), T5 (TS, GS, S (v:v:v / 2:1:1)), T6 (TS, S, FYM (v:v:v / 3:1:1)), T7 (TS, S, FYM (v:v:v / 1:1:2)) and control (GS, S, FYM (v:v:v / 2:1:1)). The samples were then analysed in laboratory. Experimental analysis on physico-chemical and
biological parameters revealed superiority of T7 (TS, S, FYM (v:v:v / 1:1:2)) in terms of pH (7.15), organic carbon (2.13%), available nitrogen (526.02 kg ha-1), available phosphorus (56.60 kg ha-1), available potassium (708.19 kg ha-1), dehydrogenase activity (18.21 μg TTF g-1 soil day-1), Phosphomonoesterase (PME) activity (46.68 54 μg p-nitrophenol/gsoil/h) and urease activity (3.39 μg NH4-N g-1 soil h-1). Whereas T4 (TS, GS, FYM (v:v:v /2:1:1)) registered superiority in terms of PME activity (50.54 μg p-nitrophenol/gsoil/h), Fluorescein diacetate (FDA) activity (11.01 μgfluorescein/gsoil/h) and Soil Microbial Biomass Carbon (SMBC) (262.25 μg/g). Subsequent to the laboratory analysis, two best potting mixtures (T7 & T4) were selected and their performance was assessed by growing a test crop, Tagetes erecta cv. Inca Orange. Considering the growth parameters, the potting media: T7 was found to be significantly superior in terms of plant spread (39.64 cm), leaf area index (4.07), fresh weight (37.72 g), yield (317.81 g/plant), and diameter (9.38 cm) of flower over T4 & control. The Benefit:Cost (B:C) ratio meaning the ratio of net returns to total cost of cultivation was determined. The B:C ratio of raising marigold flower as potted plant in T7 was 1.10 whereas the B:C ratio of the potting mixture of T7 was 2.52. This shows that T7 potting media is also economically viable choice for commercial purposes.
