“…This study demonstrated that the SOC contents of various protected cultivation years were all lower than ck, decreasing year by year. This was contrary to the results of previous studies 20,21 , but similar to the results of Song et al 22 . It may be due to the small amount of organic fertilizer applied and a small return of plant residues to soil in this area.…”

The study of the changes in the structure and quantity of the denitrifying microbial community in the protected vegetable crop field is crucial for evaluating the soil quality of long-term protected cultivation and improving the understanding of nitrogen conversion. In this study, quantitative fluorescent PCR was used, with the help of the Illumina Miseq high-throughput sequencing platform, aiming at the nosZ gene, to study the effects of protected cultivation plots 3 a, 5 a, and 7 a, and the outdoor cultivation plot (ck) on the structure and quantity of soil denitrifying microbial community. The results demonstrated that the abundance of nosZ gene in ck was significantly higher than the other treatments, and was 1.32, 1.45 and 1.69 times those of Group 3 a, 5 a and 7 a, respectively. As the cultivation year increased, the abundance of nosZ gene was decreased, and the α-diversity index was decreased. The Chao1 index and ACE index of ck were the highest. At the phylum level, the dominant group was Proteobacteria. While at the genus level, the dominant groups were Bradyrhizobium and Achromobacter. The relative abundances of Proteobacteria and Bradyrhizobium were decreased with the increase of protected cultivation time. The principal component analysis (PCA) results showed that the community structure of nosZ varied greatly with the increase of planting time. The community structures of Group 3 a and 5 a were similar, but the community structure of Group 7 a was very different from Group 3 a and 5 a. The soil available potassium (AK), ammonium nitrogen and nitrate nitrogen were the primary factors affecting the copy number, α-diversity and community structure of nosZ denitrifying microorganisms. As a conclusion, it can be seen that long-term cultivation of vegetable crops in a protected environment significantly reduced the copy number of nosZ denitrifying microorganisms and had a significant impact on the community structure.

“…In the past few decades, high output of fruit and vegetable cultivation has been maintained by the use of plastic greenhouses and films that conserve soil water and increase ambient temperatures. , Plastic features have become metaphorical pillars for the industry in many rural regions in China . Plastic greenhouses, comprising of plastic tunnels and solar greenhouses (Figure ), covered areas of 0.98 and 0.34 million ha in 2016, respectively .…”

Plastic films have become an integral part of fruit and vegetable production systems, but their release of phthalate acid esters (PAEs) is a threat to human health. The release kinetics of PAEs and measures of risk are still not well understood. We investigated 50 agricultural films, with concentrations ranging from 2.59 to 282,000 mg kg–1. The seven commercially available film types included were polyvinylchloride (PVC), metallocene polyethylene (mPE), ethylene vinyl acetate (EVA), polyolefin (PO), and three mulch films. Bis(2-ethylhexyl) phthalate (DEHP) was detected in most of films, and its release fitted well into the first-order kinetic model. The release rate of DEHP was negatively related to the film thickness. The potential carcinogenic risks of DEHP in the air of six kinds of plastic greenhouses to human health were estimated. We found that the carcinogenic risks associated with PVC and mPE greenhouse films warrant greater attention. Though EVA, PO greenhouse, and mulch films were lower risk, we advise keeping plastic greenhouses well ventilated during the first month of use to reduce direct human exposure to volatile PAEs.

“…Ouyang et al explained that as neutral and slightly alkaline soils are more conducive to the survival of bacteria and actinomycetes [47] and low pH is more beneficial to fungal growth [48]. Therefore, soil pH is considered to be the most important factor affecting the community structure of bacteria and fungi [49].…”

With increasing demand for vegetables and horticultural products, the greenhouse cultivation area is expanding at an unimaginable rate. According to Ministry of Agriculture and Rural Affairs, PRC, the total area of planting facilities, mainly plastic greenhouses, solar greenhouses and terraces, will be stabilized at more than 2 million hectares by 2025, which was just 20 thousand hectares in 1980.However, under such special conditions as higher temperature, humidity, evaporation, planting intensity, multiple cropping index, and large amounts of fertilizer application, lack of rainwater leaching and so on, greenhouse soils are susceptible to degradation characterized by deteriorated physical properties, secondary salinization and acidification [1], imbalance of soil nutrients and microbial flora, increased crop diseases and insect pests, etc [2,3].
