To be able to understand the improvement effect of activated coke on saline alkali land in northern Shanxi Province, we examined the effects of various inclusion rates of activated coke (CK, 0 g·kg-1; A10, 10 g·kg-1; A20, 20 g·kg-1; A50, 50 g·kg-1) regarding the properties of saline alkali soil plus the growth of two plant species. The outcome indicated that activated coke inclusion could raise the content of water-soluble earth aggregates, minimize earth salt content, soil pH, and the electrical conductivity (EC). Compared with CK, the mean weight diameters of the aggregates when it comes to saline-alkali soils cultivated with Puccinellia distans and maize had been increased by 5.1%-32.2%, soil pH was decreased by 0.4%-4.1%, sodium adsorption proportion (SAR) ended up being reduced by 4.8%-18.7%, therefore the EC was decreased by 7.4%-8.2%. Applying appropriate amount of activated coke could market plant development through reducing the plasma membrane harm of plant cells, increasing plant chlorophyll and Ca2+ items. The biomass of Puccinellia distans and maize both reached the utmost underneath the A20 treatment. It suggested that the use of 20 g·kg-1 activated coke (A20) in saline alkali earth could enhance soil quality within the rhizosphere soil, boost plant discerning Ca2+ absorption, thus decreasing salt injury to plant cells and improve plant growth in saline-alkali habitat.Clarifying the pattern of nitrogen absorption and usage of rice underneath the remedies of Astragalus sinicus combined with chemical fertilizer application together with structure of consumption, usage, circulation and residue of A. sinicus nitrogen in rice-soil system could supply basis to rational fertilization for rice sowing area in south Henan. In this study, undisturbed earth column simulation and isotope tracer technology of 15N were utilized to look at the differences of nitrogen uptake and utilization of rice, nitrogen nutrient stability of rice-soil system and nitrogen uptake, utilization, distribution and residue of A. sinicus nitrogen after mineralization and decomposition among seven remedies. The treatments involved 1) no fertilization (CK); 2) chemical fertilizer+22500 kg·hm-2 A. sinicus (FM1); 3) chemical fertilizer+30000 kg·hm-2 A. sinicus (FM2); 4) chemical fertilizer+37500 kg·hm-2 A. sinicus (FM3); 5) chemical fertilizer+22500 kg·hm-2 A. sinicus +lime (FM1+CaO); 6) substance fertilizer+300he utilization proportion of A. sinicus nitrogen by rice had been 23.8%-33.6%. The utilization ratio of A. sinicus nitrogen in numerous elements of rice was grain > stem and leaf > root. The residue rate of A. sinicus nitrogen in soil was 37.6%-62.4%. The loss price of A. sinicus nitrogen was 7.8%-38.6%. Comprehensively thinking about algal biotechnology nitrogen absorption and utilization of rice, nitrogen nutrient stability of rice-soil system, and the circulation circumstance of nitrogen from A. sinicus in rice, FM2+CaO ended up being Fasoracetam research buy the maximum fertilization design into the study area.Root exudates are important carriers for material change and information transfer between plant and earth, and crucial regulators of crop-soil-microorganism relationship in intercropping systems. We examined the communication between crops in intercropping system by establishing three treatments, monoculture Chinese milk vetch, monoculture rape and Chinese milk vetch intercropped with rape. The answers of root exudates were emphatically reviewed. The results showed that 391 root exudates had been recognized, with 93 of which being identified and divided into nine kinds of metabo-lites. Included in this, organooxygen compounds were probably the most abundant, primarily in the shape of ribitol. Under different planting patterns, root exudates of Chinese milk vetch and rape had been considerably different. The qualities of root exudates in intercropping had been much like monoculture rape, but notably not the same as monoculture Chinese milk vetch. One of the root exudates in various planting settings, only 9-fluorenone 1 had been negatively correlated with other people. The differential root exudates had been primarily benzenoids, lipids and lipid-like particles, natural acids and types, and organooxygen compounds. The benzenoids, lipids and lipid-like molecules had been essential types that characterized the changes of root exudates of Chinese milk vetch and rape. Chinese milk vetch intercropping with rape changed the faculties of root exudates, which were closely regarding benzenoids, lipids, and lipid-like molecules.Reasonable application of microbial agents can substantially improve soil environment while increasing the yield and high quality of vegetables. In this research, we examined the consequences of various kinds of microbial agents on the development and high quality of Brassica rapa L. ssp. chinensis Makino (non-heading Chinese cabbage) beneath the problems of no microbial broker application, fluid and solid microbe representatives application. The results revealed that compared with no microbial agent, application of fluid and solid microbial representative dramatically improved soil urease task, plant nitrogen content, leaf location, SPAD worth, and net photosynthetic rate, and enhanced vegetable production by 26.9% and 34.4% respectively. Meanwhile, the full total phenol content and ascorbic acid content of non-heading Chinese cabbage were increased and nitrate content was notably decreased by making use of microbial representatives. Hence, rational application of microbial agents promoted the yield and quality of non-heading Chinese cabbage. From the point of view of veggie growth, fluid microbial agents work fast, solid microbial agents had good lasting Dermal punch biopsy effectiveness. The cooperating application with natural and inorganic fertilizers would facilitate the excellent high quality and large yield of vegetables.We examined the effects of phosphorus (P) amounts on photosynthetic and P/Fe qualities of soybean underneath the tension of reasonable Fe and their genotypic variations, to supply a theoretical basis for logical application of P and Fe fertilizer. Six P-efficient and six P-inefficient soybean varieties screened in the early stage were utilized as experimental products.
