The rice waterlogging stress test was conducted at the experimental base of College Agriculture, Yangtze University, using Yangxian You 418 as subject, in order to investigate impact on growth during period from July August each year. Six tests with different depth (1/4 plant height (1/4PH), 2/4 PH, and 3/4 PH) duration (5 d 7 d) were set up jointing–booting stage (T1: 1/4 d; T2: T3: T4: 5 T5: T6: d;) shallow water irrigation (CK) control. height, population leaf area, above-ground dry...
The use of low molecular weight organic acids (LMWOAs) for the phytoremediation heavy metals has become a promising technique. We chose five kinds (oxalic acid (OA), acetic (AA), tartaric (TA), malic (MA), and citric (CA)) with six application rates (1, 2, 3, 4, 5, 6 mmol/kg) planted sunflowers (Helianthus annuus L.) in Cd-polluted soil to study efficiency Cd degree toxicity plants. Treatment no served as control (CK). analyzed plant height dry matter nonprotein sulfhydryl (NPT) contents...
In order to elucidate the drought resistance and high-yield mechanism of hybrid millet, we studied influence stress on photosynthetic characteristics dry matter accumulation. Our results revealed that caused lesser reduction in net rate, maximal quantum yield PSII photochemistry, excitation energy capture efficiency reaction centers millet compared normal millet. When occurred jointing stage, percentage decrease P N, Fv/Fm, Fv'/Fm', Zhangzagu3 cultivar control were 27.9%, 2.6%, 25. 5%, 1.9%,...
The large amount of nitrogen application on the North China Plain has caused a serious negative impact sustainable development regional agriculture and ecological environmental protection. Our aim was to explore effects fertilization rate groundwater depth growth attributes, soil-water soil-fertilizer contents, winter wheat yield. Experiments were carried out in micro-lysimeters at depths 60, 90, 120, 150 cm basis 0, 150, 240, 300 kg/ha rates season for wheat. Results showed that plant...
The height, number of tillers, chlorophyll (Chl) a and b content, yield rice (Oryza sativa L.) in response to alternating stresses drought waterlogging (ASDW) at the tillering jointing stages were evaluated greenhouse. This was done simulate field conditions explore appropriate water management strategies, including use rainwater. experiment tested four different ASDW treatments regular irrigation (CK) 2012 2013. light + (T-LD) severe (T-HD) stage, (S-LD) (S-HD) stage.

In recent years, the alternating occurrence of high temperature and waterlogging disasters in South China has seriously reduced yield single cropping rice. Studying changes anatomical structure rice root system could provide theoretical basis for understanding mechanisms stress. To examine interactions between stress, an experiment was set up a growth chamber consisting two temperatures (moderate, 30–34 °C high, 35–38 °C) with three depths flooding (0–5, 10 15 cm). Treatments commenced at...
The increasing soil salinity levels under reclaimed water irrigation have a negative effect on plant growth. Greenhouse experiments were conducted in 2018 and 2019 water–fresh combined irrigation. After transplanting (Day 1), rice was irrigated with clean (tap water) for 10 days to facilitate root colonisation. Subsequently, 50 11 60), then water. B. subtilis S. cerevisiae mixed into at Day 61. (20 billion colony-forming units/g) the following proportions: 5 g 0 (J1), 3.75 1.25 (J2), 2.5...
In the middle and lower reaches of Yangtze River, rainfall is greater in summer. The technology rain catching controlled irrigation rice help to save water by raising depth field after while soil content during rest period maintained at 70–100% capacity. objectives this study were evaluate growth, canopy light utilization, yield under different rain-catching modes (T1: drought low storage, T2: high storage), find optimal storage for rice. Measurements included plant height, tiller number,...
Despite the known influence of nitrogen fertilization and groundwater conditions on soil microbial communities, effects their interactions bacterial composition denitrifier communities have been rarely quantified. Therefore, a large lysimeter experiment was conducted to examine how what extent table changes reduced application would nirK-type nirS-type genes. The genes were compared at two levels N input three levels. Our results demonstrated that depression table, lead drastic shifts in...

In order to save fresh water and reduce soil salt accumulation, reclaimed water-fresh combined irrigation, i.e, irrigation with for 50 d then till harvest, was used in rice planting. Bacillus subtilis Saccharomyces cerevisiae were inoculated into the at end of irrigation. The inoculation weight per pot these microorganisms as follows: 0 g (J0), 5 (J1), 3.75 1.25 (J2), 2.5 (J3), (J4), (J5), respectively. Treatment using whole stage control (CK). plant height, tiller, physical chemical...
In order to explore the impacts of nitrogen fertilizer and straw returning methods on N2O emissions, a two-factor split-zone design was adopted for experimentation under winter wheat-summer maize rotation model in Guanzhong area Shanxi, China. The main areas interest were conventional (G) reduced (70% G); sub-areas no return (N), (S), + biochar (SB); we analyzed their emissions crop yield, relationships with related impact factors. results showed that peaks appeared wheat season treatments...
