摘要

在现代农业生产中,除草剂等生物活性物质的使用是包括高粱在内的大多数谷物种植技术的重要组成部分。众所周知,包括化学制剂在内的大多数制剂都能直接或间接地影响植物根际微生物的发育,但对其对谷物高粱根际微生物群的影响性质的研究还不够,这就说明了本研究的相关性。研究了2019-2020年除草剂Citadel 25 OD (0.6;0.8和1.0 l/ha),植物生长调节剂Endophit L1 (30 ml/ha)和生物制剂Bioarsenal (800 g/ 100 kg)。结果表明,单独或以不同组合物使用对籽粒高粱根际微生物群的数量均有刺激作用,且与除草剂Citadel 25od联合使用对籽粒高粱根际微生物群的数量增加最为显著。植物生长调节剂Endophit L1和生物修复剂Bioarsenal(与对照相比,各组根际微生物群数量平均增加29.4-80.6%)。

Microorganisms number in sorghum (Sorghum bicolor (L.) Moench) rhizosphere after herbicide, plant growth regulator, and a biopreparation use
In the modern agricultural production, the use of herbicides and other biologically active substances is an important part of the cultivation technologies of most cereals, including the grain sorghum. It is known that most preparations, including the chemical ones, can directly or indirectly influence the development of microorganisms in the rhizosphere of plants, but the nature of their effect on the microbiota of grain sorghum rhizosphere has not been studied enough, which reasoned the relevance of this research. Microbiological activity of the grain sorghum rhizosphere (hybrid Milo W) was studied during 2019–2020 under the treatment by the herbicide Citadel 25 OD (0.6; 0.8 and 1.0 l/ha), plant growth regulator Endophit L1 (30 ml/ha) and biological preparation Bioarsenal (800 g/ 100 kg). The analysis of the obtained experimental data showed that use of the studied preparations both separately and in different compositions had a stimulating effect on the number of grain sorghum rhizosphere microbiota, which was observed in its increase, especially in variants with the combined use of the herbicide Citadel 25 OD, plant growth regulator Endophit L1 and the biopreparation Bioarsenal (compared to the control the number of rhizosphere microbiota increased by 29.4–80.6% in average by groups).
