摘要

目标。探讨在固体肥料颗粒中施用农学上有用的微生物悬浮液来富集矿物肥料(偶氮磷:氮磷钾16:16:16)的可能性。方法。微生物学(在不同培养基上培养微生物,获得悬浮液,测定悬浮液滴度,显微镜),六次重复的田间小块实验(在草灰土壤上种植土豆),对每个地块的收获进行充分的统计。结果。以N80P80K80的速率将哈兹木霉(Trichoderma harzianum) PD3和芽孢杆菌属代表菌的水悬浮液施用于草灰土壤前的肥料颗粒中,以微生物富集偶氮磷,对贝拉罗扎马铃薯的产量有不同的影响。在一项为期3年的试验中,富含哈氏芽孢杆菌PD3-和芽孢杆菌102的肥料对作物产量的可靠增加作出了贡献。在多年的研究中,结合这些微生物来富集偶氮藻并没有提供稳定的效果。使用富含白僵菌44-和蜡状芽孢杆菌sb1的肥料效果不佳。施用富含芽孢杆菌102的肥料可保证马铃薯产量的最大增长。同时,实验中所有六次重复的平均参数都有较小的偏差(与其他变量相反)。结论。在灰化土上种植马铃薯时,通过添加农学上有用的微生物来提高矿质肥料效率的根本可能性已经得到证明。生物修饰偶氮磷的富集效率取决于富集的微生物。筛选有希望实现这一目的的微生物菌株,以及技术方面的研究(肥料颗粒上微生物的细胞数量,肥料富集过程中粘合剂、碳源和佐剂的使用,颗粒上微生物根据富集条件的保存条件,延长肥料类型和农作物类型的光谱,等等)是必要的。

EFFICIENCY OF MICROORGANISM-ENRICHED FERTILIZERS WHEN GROWING POTATOES
Objective. Investigate the possibility of enriching mineral fertilizers (Azofoska: NPK 16:16:16) with agronomically useful microorganisms by applying their suspensions to solid fertilizer granules. Methods. Microbiological (cultivation of microorganisms on different media, obtaining suspensions, determination of titre in suspensions, microscopy), field small-plot experiment in six repetitions (growing potatoes on sod-podzolic soil), full accounting of the harvest from each plot, statistical. Results. Enrichment of Azofoska with microorganisms by applying aqueous suspensions of Trichoderma harzianum PD3 and representatives of the genus Bacillus to fertilizer granules before their application to sod-podzolic soil at the rate of N80P80K80 had different effects on the yield of Bellaroza potatoes. T. harzianum PD3- and Bacillus sp. 102-enriched fertilizers contributed to a reliable increase in crop yield in a three-year experiment. The combination of these microorganisms to enrich Azofoska did not provide a stable effect over the years of research. The use of B. vallismortis 44- and B. cereus SB1-enriched fertilizers was not effective. The greatest increase in potato yield was ensured by the use of Bacillus sp. 102-enriched fertilizers. At the same time, minor deviations from the average parameter were reported for all six repetitions in the experiments (in contrast to other variants). Conclusion. The fundamental possibility of increasing the efficiency of mineral fertilizers by enriching them with agronomically useful microorganisms when growing potatoes on sod-podzolic soil has been shown. The efficiency of biologically modified Azofoska depended on the microorganism used for enrichment. Additional research both on the screening of microorganism strains promising for this purpose, as well as technological aspects (the number of cells of microorganisms on fertilizer granules, the use of adhesives, carbon sources and adjuvants during fertilizer enrichment, the terms of preservation of microorganisms on granules depending on the conditions of enrichment, extension of the spectrum of fertilizer types and types of agricultural crops, etc.) is necessary.
