Abstract In future climates, rice crops will be frequently exposed to water deficit and heat stress at the most sensitive flowering stage, causing spikelet sterility yield losses. Water alone in combination with significantly reduced peduncle elongation, trapping 32% 55% of spikelets within leaf sheath, respectively. Trapped had lower fertility (66% control) than those exserted normally (>93%). Average weighted was lowest (35%) but higher combined (44%), suggesting acquired...
Rotation is an effective strategy to control crop disease and improve plant health. However, the effects of rotation on soil bacterial community composition structure, health remain unclear. In this study, using 16S rRNA gene sequencing, we explored communities under four different cropping systems, continuous tobacco (control group), tobacco-maize rotation, tobacco-lily tobacco-turnip rotation. Results detrended correspondence analysis dissimilarity tests showed that structure changed...
Abstract It is important to ensure the nutritional quality and safe production of rice. Here, plot experiments were used analyze effects three soil amendments—10 t ha −1 biochar (BC), 1.5 lime (LM), 2.25 silicon–calcium fertilizer (SC)—on characteristics, rice yield double-cropping grown in mildly cadmium-polluted paddy fields. Compared with control treatment (CK), BC SC treatments significantly improved processing, appearance quality, but reduced cooking quality. All amendments cadmium (Cd)...
The interaction mechanism between crop and soil microbial communities is a key issue in both agriculture ecology. However, how respond to planting ultimately affect health still remain unclear. In this research, we explored shifted during tobacco cultivation under different rotation systems (control, maize rotation, lily turnip rotation). Our analyses showed that had general response pattern planting, as the abundances of Proteobacteria Planctomycetes increased while Acidobacteria...
Abstract In order to understand the relationship between rice ( Oryza sativa L.) yield and microbial communities soil properties of different types, clarify advantages production characteristics we investigated bacterial five representative soils (granitic sandy soil, purple clayey red yellow alluvial soil) determined their effects on yield. The granitic showed greatest potential for increasing yield, with a 39.2 g per plant, which was 24.56% higher than lowest yielding type, these...
The traditional shallow tillage method reduces soil quality and affects the efficiency of agricultural production. Using conventional rotary (12 cm) as control, Yunyan 87 test variety, paddy site, we studied effects deep (subsoiling 30 on nutrients, arbuscular mycorrhizal fungi (AMF), tobacco (Nicotiana tabacum L.) growth. results showed that increased content organic carbon, available phosphorus (AP), potassium (AK) in 20-40 cm layer. AMF community was also affected by tillage. Glomus,...
Long-term rotary tillage leads to thinning of the soil layer and low nitrogen use efficiency crops, resulting in a decrease crop yield quality. Therefore, new alternative method improve crops needs be found urgently. Here, we analyzed effects smash ridge combined with reduced application on tobacco growth development, its economic benefits. The results showed that, compared conventional 180 kg N ha−1, 30% reduction rate resulted greater root length density, more primary lateral roots rooting...
Abstract Cadmium (Cd) contamination in rice is a potential health hazard when ingested through the food chain worldwide. Reducing Cd content agronomic measures an effective way to reduce risk of human health. In order clarify correlation between temperature and light conditions accumulation (Cd-A) brown (CdBR) during field growth period (FGP) rice, consequently provide theoretical basis for selection sowing date (SD) “Low-Cd-Rice” production, experiment with different SDs was carried out by...
