■连续种植草莓通常会导致土壤传播疾病,20个氰氨化钙是一种有效的土壤熏蒸剂,猪粪常用作土壤有机肥。其对土壤微生物结构的影响,然而,尚不清楚。
■这项研究调查了氰氨化钙和猪粪在处理草莓土壤中的有效性,专门针对草莓炭疽病。我们检查了土壤和根际微生物组的物理和化学性质,并进行了网络分析。
■结果表明,氰氨化钙处理通过降低病原菌丰度,显著降低了苗期草莓的死亡率,同时在收获期增加放线菌和α变形菌。这种治疗还增强了细菌网络的连通性,通过每个操作分类单位(OTU)的平均连通性来衡量,超越其他治疗。此外,氰氨化钙显著提高了有机物的含量,有效钾,土壤中的磷是草莓抗病性和产量的关键因子。
■总的来说,在草莓连作土壤中施用氰氨化钙可以有效降低炭疽病的发病率。这可能是通过改变土壤理化性质和增强细菌网络稳定性,从而减少了炭疽病的复制。这项研究强调了氰氨化钙在疾病控制和土壤养分增强方面的双重益处,表明其作为可持续草莓种植有价值的工具的潜力。
UNASSIGNED: Continuous strawberry cropping often causes soil-borne diseases, with 20 calcium cyanamide being an effective soil fumigant, pig manure can often be used as soil organic fertilizer. Its impact on soil microorganisms structure, however, remains unclear.
UNASSIGNED: This study investigated the effectiveness of calcium cyanamide and pig manure in treating strawberry soil, specifically against strawberry anthracnose. We examined the physical and chemical properties of the soil and the rhizosphere microbiome and performed a network analysis.
UNASSIGNED: Results showed that calcium cyanamide treatment significantly reduces the mortality rate of strawberry in seedling stage by reducing pathogen abundance, while increasing actinomycetes and Alphaproteobacteria during the harvest period. This treatment also enhanced bacterial network connectivity, measured by the average connectivity of each Operational Taxonomic Unit (OTU), surpassing other treatments. Moreover, calcium cyanamide notably raised the levels of organic matter, available potassium, and phosphorus in the soil-key factors for strawberry disease resistance and yield.
UNASSIGNED: Overall, applying calcium cyanamide to soil used for continuous strawberry cultivation can effectively decrease anthracnose incidence. It may be by changing soil physical and chemical properties and enhancing bacterial network stability, thereby reducing the copy of anthracnose. This study highlights the dual benefit of calcium cyanamide in both disease control and soil nutrient enhancement, suggesting its potential as a valuable tool in sustainable strawberry farming.
