摘要
2013-2016年,在波兰托马什科沃(北纬53°72′;东经20°42′)的研究与教育中心进行了冬小麦(Triticum aestivum L.)栽培的田间试验。150和200 kg ha−1的氮施肥以及0.5和1.5 kg ha−2的锰叶面施用是研究因素。镰刀菌对小麦的侵扰是由作物生长过程中的栖息地条件决定的。氮和锰施肥都不影响镰刀菌的存在。小麦穗上的症状,但虫害强度随着籽粒中氮和锰含量的增加而降低。只有脱氧雪腐镰刀菌烯醇(DON)水平与镰刀菌感染有关。将氮肥施肥率从150 kg ha−1增加到200 kg ha−2会导致粮食受到更高的毒素污染。用锰补充氮肥可以减少小麦籽粒中真菌毒素的数量。小麦产量主要受小麦生长期不同天气条件的影响。施氮和施锰均不影响小麦产量。本研究的目的是研究天气条件和氮锰施肥对冬小麦产量、镰刀菌枯萎病发生和真菌毒素水平的影响。
Mycotoxin Level in Winter Wheat Grain as Impacted by Nitrogen and Manganese Fertilisation
A field experiment with winter wheat (Triticum aestivum L.) cultivation was conducted at the Research and Education Centre in Tomaszkowo, Poland (53°72′ N; 20°42′ E) in the years 2013–2016. Fertilisation with nitrogen at 150 and 200 kg ha−1 and foliar application of manganese at 0.5 and 1.5 kg ha−1 were the research factors. Wheat infestation by Fusarium spp. was determined by the habitat conditions during crop growth. Neither nitrogen nor manganese fertilisation affected the presence of Fusarium spp. symptoms on wheat ears, but the infestation intensity decreased with increasing nitrogen and manganese content in the grain. Only the level of deoxynivalenol (DON) was correlated with Fusarium spp. infestation. Increasing the nitrogen fertilisation rate from 150 kg ha−1 to 200 kg ha−1 resulted in higher grain contamination with toxins. Supplementation of nitrogen fertilisation with manganese reduced the number of mycotoxins in wheat grain. The grain yield was mainly affected by the varied weather conditions during the wheat-growing periods. Neither nitrogen nor manganese fertilisation differentiated the wheat grain yield. The objective of this study was to examine the impact of the weather conditions and nitrogen and manganese fertilisation on the grain yield, occurrence of Fusarium head blight and mycotoxin level in winter wheat grain.

Applied Sciences (ISSN 2076-3417) provides an advanced forum on all aspects of applied natural sciences. It publishes reviews, research papers and communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files and software regarding the full details of the calculation or experimental procedure, if unable to be published in a normal way, can be deposited as supplementary electronic material.
