“…Phosphorus is an essential nutrient element for plant growth and is closely related to plant growth and development, material energy metabolism, and photosynthetic respiration ( Zhang et al, 2016 , 2018 ). During the growth of field crops, lack of phosphorus often leads to poor growth and development, which affects its yield and quality ( Zhang et al, 2018 ; Wang et al, 2020 ). Although most soils are rich in phosphorus, most of them are recalcitrant phosphorus that cannot be absorbed and utilized by plants.…”

Phosphorus content and root zone temperature are two major environmental factors affecting maize growth. Both low phosphorus and root zone high temperature stress significantly affect the growth of maize, but the comprehensive effects of phosphorus deficiency and root zone warming are less studied. This study aimed to explore the effects of phosphorus deficiency and root zone warming on the root absorption capacity, total phosphorus content, and photosynthetic fluorescence parameters of maize seedlings. The results showed that maize shoots and roots had different responses to root zone warming and phosphorus deficiency. Properly increasing the root zone temperature was beneficial to the growth of maize seedlings, but when the root zone temperature was too high, it significantly affected the root and shoot development of maize seedlings. The root zone warming had a more significant impact on the root system, while phosphorus deficiency had a greater impact on the shoots. Phosphorus content and root zone warming had a strong interaction. Under the comprehensive influence of normal phosphorus supply and medium temperature in the root zone, the growth of maize seedlings was the best. Under the combined effects of low phosphorus and high temperature in the root zone, the growth was the worst. Compared with the combination of normal phosphorus and root zone medium temperature treatment, the dry mass of the low-phosphorus root zone high temperature treatment was decreased by 55.80%. Under the condition of low-phosphorus too high root zone temperature reduced root vitality, plant phosphorus content, which in turn affected plant growth and light energy utilization efficiency. In the case of sufficient phosphate fertilizer supply, appropriately increasing the soil temperature in the root zone is beneficial to increase the absorption and utilization of phosphorus by plants and promote the growth and development of maize seedlings.

“…Compared to nitrogen (N), P is a non‐renewable resource. Despite large amounts of organic and inorganic P in natural soils, only 0.1% of the total P is available to plants because of the low solubility and rapid conversion of P compounds to unavailable or less available P after fertilizer application in the soil (Bhadouria et al, 2017; Wang et al, 2020). Moreover, the leaching and run‐off also result in the loss of chemical P fertilizer (Carvalho, 2017; Kochian, 2012).…”

“…The nitrate absorption pathway of mycorrhizal symbiosis has also been shown to promote the nitrogen absorption e ciency of gramineous crops [19]. The presence of maize increased the secretion of carboxylate in alfalfa root system, improved the availability of soil phosphorus, and then promoted the growth of maize in the aboveground and absorption of phosphorus [20]. Therefore, the relationship between microorganisms, plants and soil under intercropping of maize and peanut can not only reveal the adaptation of plants to the microecological environment but also improve resource utilization e ciency, reduce fertilizer application, protect the ecological environment and help to develop sustainable agriculture.…”

Background: Intercropping, a diversified planting pattern is currently the subject of major global research, but uncertainty remains about the rhizosphere interaction of intercropped maize and peanut, which increases nitrogen uptake. We explored the changes in soil physicochemical properties, nutrient uptake and use, and microbial community structure in wide-strip intercropped maize and peanut. Results: The results from three treatments, sole maize (SM), sole peanut (SP) and intercropping of maize and peanut (IMP), showed that intercropping maize (IM) had a marginal advantage and that the nutrient content of roots, stems and grains in side-row maize was better than that of middle intercropping maize (MIM) and SM. And the yield of intercropped maize was higher than sole cropping. Compared with SM and SP, the soil nitrogen content (TN) in IM and intercropping peanut (IP) was lower and increased the soil enzyme activities of nitrate reeducates (NR) and peroxidase (POD), showing a significant negative correlation with soil TN. And decreased the soil enzymes activities of Pro and DHO, showing a positively correlation with soil TN. The diversity and richness of bacteria and fungi was decreased in IM rhizosphere soil, however, that richness of fungi was increased in IP rhizosphere soil. The RB41, Candidatus-udaeobacter, Stropharia, Fusarium and Penicillium were correlated with soil enzyme activity. In addition, intercropping enriched the functional diversity of bacterial community and reduced the pathogenic fungi. Conclusion: IMP changed the rhizosphere soil bacterial and fungal community structure and composition, enriched nitrogen-fixing bacteria in the IP rhizosphere soil, promoted the nitrogen content of IM and provided a scientific basis for promoting IMP in northeastern China.
