Greenhouse eggplant monocropping in China has contributed to the aggravation of soil-borne diseases, reductions crop quality and yield, degradation physical chemical soil properties. Crop rotation is one effective way alleviating problems continuous cropping worldwide; however, few studies have reported changes bacterial community structures properties after Brassica vegetables had been rotated with greenhouses. In this experiment, mustard-eggplant (BFN) oilseed rape-eggplant (BFC) rotations...

Planting pattern affects canopy structure of crops and influences other physiological characteristics such as light interception radiation use efficiency. In the current paper, effects planting patterns on structure, interception, photosynthetic at silking stage two maize (Zea mays L.) cultivars (Beiyu288 Xianyu 335) were examined in three narrow–wide rows (1) 30 cm + 170 (P1, 6.4 plants m–2), (2) 40 cm+90 (P2, uniform row 65 (control, i.e. CK, m–2). The ratio leaves perpendicular to was...

In China, narrow-wide row planting pattern has been advocated for maize (Zea mays L.) production. However, no previous study clearly elucidated the complexity of factors affecting canopy such as microclimatic factors, and effect photosynthesis in pattern. The current was undertaken to identify patterns that influence conditions two cultivars (Beiyu288 Xianyu335) grown three patterns: rows (1) 30 cm + 170 (P1, 6.4 plants m-2), (2) 40 90 (P2, (3) uniform 65 (CK, conventional control, m-2)....

Summary Sustainable agricultural management practices improve soil processes, prevent erosion and consequently enhance crop productivity. The integrated practice (IP) developed in northeast China, by altering row spacing of planting, adopting no‐tillage returning all residues, showed great benefit sustaining yield. However, its effect on the microbiome remains largely elusive. This study evaluated 12‐year structure activity microbial community at different depths China's Mollisols zone....

High salt stress significantly depresses carbon assimilation and plant growth in wheat (Triticum aestivum L.). Salt acclimation can enhance the tolerance of plants to stress. Priming with abscisic acid (1 mmol ABA) was applied during (30 NaCl) process investigate its effects on subsequent (500 NaCl). The results showed that priming ABA modulated leaf concentration maintain better water status acclimated plants. Also, drove antioxidant systems protect photosynthetic electron transport against...

Throughout China, traditional Chinese medicine (TCM) is available alongside western medicine. The aim of this study was to investigate patients' familiarity with, trust in, and willingness pay for services disease prevention health care in community centres, identify strategies service improvement. A cross-sectional conducted, a random sample 599 patients were surveyed centres five cities. Chi-square test, Kruskal-Wallis H binary logistic analysis used factors associated with TCM care. Of...

Conservative agricultural practices have been adopted to improve soil quality and maintain crop productivity. An efficient intercropping of maize with mushroom has developed in Northeast China. The objective this study was evaluate compare the effects planting patterns on diversity structure bacterial communities at a 0–20 cm depth black zone experiment consisted monoculture mushroom, split-plot arrangement. characteristics microbial were performed by 16S rRNA gene amplicom sequencing....

Sustainable agricultural management practices have attracted increasing attention due to their significant roles in benefiting the functions and sustainability of agro-ecosystems. An integrated practice (IP) a maize cropping system was developed by changing row spacing, adopting no-tillage residue return Northeast China. A 12-year field study carried out evaluate effect IP conventional (CP) on soil physical properties, microbial biomass enzyme activity during season. The results showed that...

Arbuscular mycorrhizal fungi (AMF) are ancient and ubiquitous soil microorganisms, which can form mutually beneficial association with most terrestrial plants. Within the symbiotic relationship, AMF helps their host plants to absorb nutrients such as nitrogen phosphorus while obtains carbon from hosts. plays an important role in agricultural ecosystem, including promoting plant growth, improving crop quality, increasing stress resistance, stabilizing structure, keeping ecological balance,...
