这项研究评估了单独和综合应用无机(NPK)的效果,商业有机(NC),和生物学(MIX,混合菌株Ensifermeliloti和铜绿固氮菌)肥料对芝麻菜生物量的化学特性及其产量的影响,以及与对照处理(Ø)相关的实验后土壤微生物参数的变化。实验是在半受控温室条件下进行的,在锅里,从三月的第四个十年到九月的第二个十年,2023年,在三个切割时间/范围内,在一个农业季节,用Vertisol土壤。对于土壤表征,分析了以下参数:使用筛分和沉降程序进行的粒度组成;土壤酸度电位法;通过Kotzmann方法进行的SOM-土壤有机质;使用CNS分析仪进行的总氮;可用的P分光光度法;可用的K-火焰光度法;在agarized土壤提取物培养基上的微生物总数;固体Czapek琼脂上的真菌;固体KrasiljnikovAzotapo上的放线菌;在含有甘露醇的Fyodorov液体培养基上;在含有天冬酰胺的液体培养基上的氨化器;和脱氢酶活性分光光度法。对于植物表征,确定了以下参数:N和C,都在CNS分析仪上;分光光度计上的P;火焰光度计上的K;空气干燥的生物量。在综合使用有机和生物肥料的处理中发现了对所有微生物参数的刺激作用,除了真菌,在单独的无机和有机肥料处理中生长更好。一般来说,对植物化学参数的刺激作用表现在无机和生物的组合,有机和生物,无机和有机施肥处理,并在不受精的治疗中受到抑制,在所有三个区域中,这也可以说是植物产量。与第一和第三相比,第二带观察到所有施肥处理对化学参数的积极影响。NPK+MIX处理的总收率为121%,在NC+MIX处理中,与对照组(Ø)相比高出87%。总的来说,无机和生物的综合利用,有机和生物,无机和有机肥料,分别,可作为芝麻菜种植中的最佳施肥处理。
This study evaluated the effects of solely and integrated application of inorganic (NPK), commercial organic (NC), and biological (MIX, mixed strains Ensifer meliloti and Azotobacter chroococcum) fertilizers on the chemical characteristics of
arugula biomass and its yield, as well as changes in soil microbiological parameters after the experiment in relation to the control treatment (Ø). The experiment was performed in semi-controlled greenhouse conditions, in pots, from the 4th decade of March to the 2nd decade of September, in 2023, at three cutting times/swaths, during one agricultural season, with Vertisol soil. For soil characterization, the following parameters were analysed: granulometric composition using sieving and sedimentation procedure; soil acidity-potentiometrically; SOM-soil organic matter by Kotzmann method; total N using CNS analyser; available P-spectrophotometrically; available K-flame photometrically; total number of microorganisms on an agarized soil extract medium; fungi on a solid Czapek agar; actinomycetes on a solid Krasiljnikov agar with saccharose; Azotobacter spp. on a liquid Fyodorov medium with mannitol; ammonifiers on a liquid medium with asparagine; and dehydrogenase activity-spectrophotometrically. For plant characterization, the following parameters were determined: N and C, both on CNS analyser; P on spectrophotometer; K on flame photometer; air-dried yield biomass. A stimulative effect on all microbiological parameters was found in the treatment with integrated use of organic and biological fertilizer, except for fungi, which grew better in the treatments with separate inorganic and organic fertilizers. Generally, the stimulative impact on plant chemical parameters manifested in combined inorganic and biological, organic and biological, and inorganic and organic fertilization treatments, and was inhibited in treatment without fertilization, in all three swaths, which could also be stated for the plant yield. Positive influence of all fertilization treatments on chemical parameters was observed for the second swath in relation to the first and the third. The total yield in the NPK+MIX treatment was 121%, and in the NC+MIX treatment, it was 87% higher compared to the control (Ø). In general, integrated use of inorganic and biological, organic and biological, and inorganic and organic fertilizers, respectively, could be proposed as an optimal fertilization treatment in
arugula cultivation.
