Abstract

The results of research on the influence of biologics based on rhizosphere microorganisms on the yield of spring wheat grain on different backgrounds of mineral nutrition on sod-podzolic light-loamy soil are presented. It was found that inoculation of spring wheat seeds with biologics provides an increase in grain yield by 1.2–1.3 times, while nitrogen fertilizer at doses of N₄₅ and N₉₀ provide increases by two and 3.5 times, respectively. The collection of raw protein due to the improvement of nitrogen nutrition increases with the introduction of N₄₅ by two times and with N₉₀ by 3.6 times; that with the use of biological products is by 25–45%. The vast majority of the nitrogen consumed accumulated in the grain, while less in the straw. The grain of spring wheat, while improving the supply of nitrogen to plants during the growing season, contained 76–81% of thiselement from the accumulated harvest. It is concluded that the use of biologics on sod-podzolic light-loamy soil has a positive effect on the growth of spring wheat grain mass, improves the quality of products, and increases the payback of mineral fertilizers by increasing the yield.

氮肥和生物制剂对春小麦产量和品质的影响

摘要

提出了根际微生物对春小麦籽粒产量的影响的研究结果。研究发现，用生物制剂接种春小麦种子可使谷物产量增加1.2-1.3倍，而氮素N ₄₅和N ₉₀剂量的氮肥分别增加2倍和3.5倍。N ₄₅的两倍和N ₉₀的引入使由于氮营养改善而产生的粗蛋白收集量增加。3.6倍; 使用生物产品的比例为25–45％。消耗的氮的绝大部分累积在谷物中，而秸秆中的氮较少。春小麦籽粒虽然在生长季节改善了植物的氮供应，但其中的76-81％来自累积收获。结论是，在草皮-土壤-轻质壤土上使用生物制剂对春小麦籽粒的生长具有积极作用，提高了产品质量，并通过增加产量增加了矿物肥料的投资回报。
