| 1 | Combined Application of Organic and Inorganic Fertilizers on Black Soil Fertility and Maize Yield显示文摘By two years (2007-2008) located fertilizer experiment, the effect of long-term combined application of organic and inorganic fertilizers on black soil fertility and crop yield was investigated in Shuangcheng City, Heilongjiang Province. The results showed that the combined application of organic and inorganic fertilizers could increase the organinc matter, alkaline nitrogen, available phosphorus and available potassium. At the same time, the increasing application of organic fertilizer could reduce the soil bulk density and improve the field moisture capacity. Field moisture capacity and organic matter of the combined application of high quantities of organic manure and inorganic fertilizers A1B5 treatment increased the fastest, organic matter increased by 3.33 g · kg-1 and field moisture capacity increased by 11.25% than the beginning of the experiment. Under the same fertilization, the combined application of organic and inorganic fertilizers' increasing production range was higher than the single chemical fertilizers' which was from 0.8% to 9.4%. The results showed that the combined application of organic and inorganic fertilizers could increase the nutrient contents of soil and also was the highest productivity contribution to black soil fertility. It was the best fertilization structure of increasing productivity level and improving the soil fertility. | ZHAO Jinwei ZHOU Lianren | 2011 | Journal of Northeast Agricultural University(English Edition)2011，18，2： | 5 |

| 15 | Studies on Fast Remediation of Soda Meadow Alkaline Soil显示文摘Researches on models of remediation quickly in soda meadow alkaline soil, and dynamic variation of water-salt in saline soil of Zhaozhou County were studied systematically from 2001 to 2006. Realize the vegetation cover of those years through the artificial planting, mixed seeding lyme grass (Elymus dahuricus Turcz) and melilot in the mode of rotary tillage and deep loosening in lower and medium saline soils. The results showed that there was remarkable relationship between net evaporation (difference of precipitation and evaporation) and total salt content in the soil. The net evaporation could be used as a new method to forecast the dynamics variation of salt to ensure the pasture optimum sowing time. Realize the autumnal vegetation cover of those years through direct planting on the bourgeon layer of soda meadow alkaline soil, on the other hand, the covered pasture made the function of restraining salt and alkaline content to realize the biology reverse succession quickly. Forage seeds were seeded directly on the seeding bed of soda alkaline meadow at the end of July. In fall of the same year, a certain amount of biomass was obtained. The model, which has remarkable economical efficiency and use widely, represented the innovative model for the fast vegetation restoration on the soda alkaline meadow soil. | ZHOU Lianren SUN Yankun LI Dawei | 2010 | Journal of Northeast Agricultural University(English Edition)2010，17，4： | 0 |
| 16 | Synthesis of zeolite A and zeolite X from electrolytic manganese residue,its characterization and performance for the removal of Cd^(2+)from wastewater显示文摘Electrolytic manganese residue(EMR)can cause serious environmental and biological hazards.In order to solve the problem,zeolite A(EMRZA)and zeolite X(EMRZX)were synthesized by EMR.The pure phase zeolites were synthesized by alkaline melting and hydrothermal two-step process,which had high crystallinity and excellent crystal control.And the optimum conditions for synthesis of zeolite were investigated:NaOH-EMR mass ratio=1.2,L/S=10,hydrothermal temperature=90℃,and hydrothermal time=6 h.Then,EMRZA and EMRZX showed excellent adsorption of Cd^(2+).When T=25℃,time=120min,pH=6,C0=518 mg·L^(-1),and quantity of absorbent=1.5 g·L^(-1),the adsorption capacities of EMRZA and EMRZX reached 314.2 and 289,5 mg·g^(-1),respectively,In addition,after three repeated adsorption-desorption cycles,EMRZA and EMRZX retained 80%and 74%of the initial zeolites removal rates,respectively.Moreover,adsorption results followed quasi-second-order kinetics and monolayer adsorption,which was regulated by a combination of chemisorption and intra-particle diffusion mechanisms.The adsorption mechanism was ions exchange between Cd^(2+)and Na+.In summary,it has been confirmed that EMRZA and EMRZX can be reused as highly efficient adsorbents to treat Cd^(2+)-contaminated wastewater. | Wenlei Li Huixin Jin Hongyan Xie Lianren Ma | 2023 | Chinese Journal of Chemical Engineering2023，62，10： | 0 |
| 17 | Effects of phosphorus on nutrient uptake and rhizosphere acidification of soybean (G/ycine max L.)显示文摘Pot experiment was conducted to examine how application of KH_2PO_4(0-165 mg·kg^(-1)P)to affect nutrient ion uptake and rhizosphere acidification of soybean(Glycine max L.) grown in greenhouse for 90 days.When supplied of 82 and 165 mg·kg^(-1) P, soybeans showed excessive poison.Under all kinds of P levels,the K,Ca,Na and Mg concents in plant tissues were as below order: K was nodules>roots>pods>shoots;Ca was shoots>roots>nodules>pods;Na was roots>nodules>pods>shoots and Mg was shoots>nodules>roots>pods.K concent in plant tisssues had greater effect on rhizosphere acidification than other cations in this experiment irrespective of P supply,and was significantly negative to pH.Na concentration was significantly positive to pH.Excessive P supply induced rhizosphere acidification,pH decreased as P supply increased from 82 to 165 mg·kg^(-1).Ash alkalinity in shoots and roots was significantly positively correlated with rhizosphere pH irrespective of P supply.All these results suggested that P supply affected nutrient uptake,induced ash alkalinity to increase and rhizosphere pH to decrease in soybean. | MIAO Shujie QIAO Yunfa HAN Xiaozeng ZHOU Lianren | 2007 | Journal of Northeast Agricultural University(English Edition)2007，14，3： | 0 |
