The cultivated land area in China is approaching the red line for farmland protection. Newly reclaimed possesses a large exploratory potential to become reserved resource. Identifying fertilization strategy vital improving poor properties and weak fertility of newly land. An experiment was conducted study effects traditional compound fertilizer (Fc) or bio-organic (Ft), alone combination with biochar addition (6.85 t·ha−1 13.7 t·ha−1) on growth, photosynthesis, yield quality Chinese small...

The effects of root exudates and irrigation with treated wastewater on heavy metal mobility soil bacterial composition under intercropping remain poorly understood. We conducted a pot experiment maize soybean grown in monocultures or intercultures, irrigated either groundwater wastewater. In addition, the pre-collected from hydroponic culture mono- inter-cropped were applied to at four levels (0 %, 16 32 % 64 %). results showed that application increased plant growth nutrient content....

The transfer of antibiotic resistance genes (ARGs) in soil under reclaimed water irrigation poses a potential environmental risk. Regulation NPK fertilizer could influence the behavior bacterial communities, mobile genetic elements (MGEs), and properties, which determine fate ARGs. To identify key element realize efficient regulation, we explored effect individual N, P, K fertilization on ARG variation tomato rhizosphere bulk soils. Compared with an unfertilized treatment, N resulted greater...

The scarcity of freshwater resources has increased the use nonconventional water such as brackish water, reclaimed etc., especially in water-scarce areas. Whether an irrigation cycle using and (RBCI) poses a risk secondary soil salinization to crop yields needs be studied. Aiming find appropriate for different resources, pot experiments were conducted study effects RBCI on microenvironments, growth, physiological characteristics antioxidation properties crops. results showed following: (1)...

Not only is solving freshwater resource shortages effective but also an important measure for realizing the sustainable development of agriculture through and use unconventional water resources. This pot experiment investigated role exogenous silicon in risk secondary soil salinization growth physiology Lvxiu pakchoi cabbage under irrigation by using brackish alone (BW), reclaimed (RW), compound with at a ratio 1:1, as well distribution soil–crop system. The results showed that extension...

Soil water repellency affects soil movement during infiltration significantly. The HYDRUS software has been popularly applied in dynamics simulation for many years, but its performance water-repellent (WR) soils not assessed thoroughly. Our objectives are to assess the of HYDRYUS-1D cumulative (CI), wetting front (Z f ), and volumetric content (θ v ) horizontal imbibition vertical wettable, slightly WR, strongly WR soils. key parameters α n retention curves were inversely estimated by...

Rational utilization and improvement of agricultural water resources has been is still the focus research on developing efficient green agriculture in various countries. Thus, exploitation usage non-traditional hold substantial significance management sustainable agriculture. However, their reuse may induce secondary soil salinization impose stress crops. To address challenges salinity plant under brackish-reclaimed irrigation, this study aimed to investigate effects silicon (Si) fertilizer...

The use of unconventional water resources is an effective way to alleviate the scarcity freshwater resources, especially in areas where scarce, but reclaimed abundant. To explore reasonable utilization brackish and water, a pot experiment was carried out study risk secondary soil salinization. set two salinity levels four mixed irrigation ratios as control. results showed that: (1) Soil moisture content, salt pH, ESP, SAR decreased with increase proportion mixture. (2) exchangeable Ca2+...

Abstract The sustainable development of agriculture in Xinjiang Province, China has been threatened by soil salinization. Biochar can be an effective amendment to improve salt‐affected soils. An appropriate amount biochar application and incorporation depth are key factors for amending performance. However, few studies have investigated the effects differing amounts on saline properties, including water infiltration, using a combination experiments simulations. In this study, acidulated was...

Abstract Water resource shortage has become an important factor limiting agricultural sustainability in China. In addition, the development and utilization of unconventional water resources are greatly for alleviating deficit. The Pakchoi was cultivated by using surface soil (0–20 cm) from field this pot experiment. experiment lasted approximately 1 month to study microbial community structure variation under brackish reclaimed irrigation. 16S rDNA high-throughput assays revealed that...

Brackish water has to be used irrigate crops for harvest due the scarcity of freshwater resources. However, brackish irrigation may cause secondary soil salinization. Whether combined utilization different non-conventional resources could relieve risk salinization not been reported. In order explore safe and rational in areas where are scarce, a pot experiment was conducted study mixed rotational using reclaimed or freshwater. The results indicated that: (1) Short-term did salinization,...

To investigate the effects of different manures in combination with fulvic acid on abundance N-cycling functional genes greenhouse soils, Chinese cabbage was planted for three growing seasons. A total six treatments—pig manure (P), pig + (PH), chicken (C), (CH), sheep (S), (SH) and no fertilization (CK)—were set up. The 13 soil (gdhA, amoA-1, amoA-2, amoB, narG, nirK-1, nirK-2, nirK-3, nirS-1, nirS-2, nirS-3, nosZ nifH) were investigated after harvest third season using a gene chip approach....

Based on computational fluid dynamics and large-eddy simulation technologies, a numerical method of moving thunderstorm field is established by considering the impinging jet model. In addition, influence movement speed storm center velocity changes characteristics wind presented. By drawing horizontal radial profile curves, vertical curves velocity, speed, transient downburst are illustrated. The results demonstrate that exhibits clear asymmetric characteristics. As height from ground...

While previous studies have suggested that biochar, nitrification inhibitors, and urease inhibitors may reduce soil greenhouse gas emissions, their effectiveness in soils irrigated with alternative water resources remains unclear. To compensate for this, reclaimed livestock wastewater were utilized as alongside groundwater control. Nitrapyrin N-(n-butyl) thiophosphoric triamide biochar applied to the either individually or combination, a no-substance treatment (NS) was included comparison....
