By using potassium permanganate impregnation method,common activated carbon was processed in 0. 079 mol/L KMnO4 solution at 650℃ to obtain modified activated carbon loaded with manganese oxide,and then different quantities of common activated carbon and modified activated carbon were used to adsorb 0. 3 mg/m^3 formaldehyde. The results showed that carbon and manganese atoms on the surface of modified activated carbon could adsorb formaldehyde,and the removal rate of 0. 3 mg/m^3 formaldehyde by 30 g of modified activated carbon reached 80%,increased one time compared with that by common activated carbon. Different amounts of activated carbon had various effects on the adsorption of formaldehyde,and the best usage of common activated carbon and modified activated carbon was 100 and 30 g respectively.

Based on a long-term location test lasting for 20 years, the accumulation and migration of phosphorus in purple soil was studied. The results showed that P2Os input in paddy-upland rotation was 120.0 kg/（ hm2 · a）（a conventional level of phosphorus application）, and P had a surplus of 53.9 kg/（hm2 · a）. Phosphorus accumulating in soil increased available phosphorus （Olsen-P） content, and the positive correlation between P changing balance and Olsen-P change in wheat-rice rotation was extremely significant. The mixed application of organic fertilizer and chemical P fertilizer can speed up accumulation of available phosphorus in soil. Olsen-P content in all treatments with P fertilizer was higher in 0 -60 cm soil than that of treatments without P fertilizer, and Phosphorus applied in surface soil moved to soil at a depth of 60 cm, increasing risk of P leakage and loss. The migration of phosphorus in soil is affected by P input, type of organic fertilizer and planting method. The quantities of phosphorus moving down increased with the increase of P input, and the application of pig manure can lead to migration of phosphorus in soil more easily compared with straw. The migration of phosphorus from soil to water mainly occurred in the first ten days after rice was transplanted, and paddy field drainage should not be conducted in the first 30 days after rice was transplanted.

As gradual improvement of living environment and indoor decoration form diversification, the indoor air pollution has become the ＂invisi- ble killer＂ harming human health, and has been listed as one of ten big threats to human health by the World Health Organization, which also be- came one of hot issues concerned by countries all over the world. In this paper, through the determination of formaldehyde in some houses of Binzhou, the release of formaldehyde with the increase of time was explored; change of formaldehyde in the same residence in different functional areas was analyzed; the influence of the temperature, humidity and plant to formaldehyde content was also analyzed.

Through exploring the cumulative contents of Pb, Cu and Cd, the 3 common heavy metals in air pollution, in leaves of some widely-applied green plants in different functional areas in urban districts of Binzhou City, this paper figured out its relationship with functional areas in the city, and whether green plants are selective in adsorbing heavy metals or not. The research found that cumulative content of Cu and Cd varied greatly in leaves of the same species in different functional areas, and also in leaves of different species in the same area. Populus tomentosa and Sophora japonica had the strongest capacity of adsorbing Pb, Cu and Cd in the air, which is a useful reference for the urban landscaping of Binzhou City.

Based on the monitoring data of visibility,particulate matter（ PM2. 5 and PM10） and atmospheric pollutants（ SO2,NO2,CO,and O3）,and meteorological factors（ temperature,humidity,and wind speed） at the six automatic air monitoring stations in Binzhou City from December 2016 to February 2017,the correlations between visibility and influencing factors were analyzed to study the main influencing factors of atmospheric visibility. The results showed that the daily average concentration of particulate matter negatively correlated with atmospheric visibility,and the correlation between PM2. 5 concentration and atmospheric visibility was more obvious than that of PM10 concentration. Among atmospheric pollutants,the daily average concentration of CO,NO2 and SO2 also negatively correlated with atmospheric visibility,while there was a positive correlation between visibility and the daily average concentration of O3. Daily average temperature and wind speed positively correlated with visibility,while relative humidity negatively correlated with visibility. Wind speed,relative humidity and PM2. 5 had strong correlation with visibility,and the linear correlation coefficient R2 was 0. 501 6,0. 446 6,and 0. 205 8 respectively,so wind speed,relative humidity,and PM2. 5 were the main factors influencing the decrease of atmospheric visibility on a hazy day in winter.

Cassava is a staple food, feed and bioenergy crop important to the world especially in the *** cassava is characterized by powerful carbohydrate accumulation but its wild progenitor is ***, we investigated the transcriptional differences of eight c DNA libraries derived from developing leaf, stem and storage root of cassava cv. Arg7 and an ancestor line,W14, using next generation sequencing system. A total of41302 assembled transcripts were obtained and from these,25961 transcripts with FPKM≥3 in at least one library were named the expressed genes. A total of 2117, 1963 and3584 transcripts were found to be differentially expressed in leaf, stem and storage root(150 d after planting),respectively, between Arg7 and W14 and ascribed to 103,93 and 119 important pathways in leaf, stem and storage root, respectively. The highlight of this work is that the genes involved in light response, such as those for photosystem I(PSA) and photosystem II(PSB), other genes involved in light harvesting, and some of the genes in the Calvin cycle of carbon fixation were specially upregulated in leaf. Genes for transport and also for key rate-limiting enzymes(PFK, PGK and PK, GAPDH)coupling ATP consumption in glycolysis pathway were predominantly expressed in stem, and genes for sucrose degradation(INVs), amylose synthesis(GBSS) and hydrolysis(RCP1, AMYs), the three key steps of starch metabolism, and transport associated with energy translocation(ABC, AVPs and ATPase) and their upstream transcription factors had enhanced expression in storage root in domesticated cassava. Co-expression networks among the pathways in each organs revealed therelationship of the genes involved, and uncovered some of the important hub genes and transcription factors targeting genes for photosynthesis, transportation and starch biosynthesis.
