Combined Application of Organic and Inorganic Fertilizers on Black Soil Fertility and Maize Yield

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 AtB5 treatment increased the fhstest, organic matter increased by 3.33 g. kg 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.

Characteristic Town Environment Design Based on Brand Community——A Case Study of the Forest Hot Spring Township in Ninghai

Brand community is a specific,geographically-unconstrained community based on specific brands and is constructed with consumer groups of different levels,choices and territories. The development issues of characteristic towns were incorporated into the perspective of brand communities,and the development connotation of characteristic towns was discussed in light of the definition,constituent elements and characteristics of brand communities,and a functional platform with organic combination of industry,city,people and literature was established through the exploration of Ninghai forest hot spring town,combined with local spatial resources. Based on this,the planning and design of Ninghai forest hot spring town will form a characteristic town that integrates industrial functions,cultural functions and community functions.

Growth of a-Plane GaN Films on r-Plane Sapphire by Combining Metal Organic Vapor Phase Epitaxy with the Hydride Vapor Phase Epitaxy

Hydride vapor phase epitaxy （HVPE） is utilized to grow nonpolar a-plane GaN layers on r-plane sapphire templates prepared by metal organic vapor phase epitaxy （MOVPE）. The surface morphology and microstructures of the samples are characterized by atomic force microscopy. The full width at half maximum （FWHM） of the HVPE sample shows a W-shape and that of the MOVPE sample shows an M-shape plane with the degree of 0 in the high-resolution x-ray diffraction （HRXRD） results. The surface morphology attributes to this significant anisotropic. HRXRD reveals that there is a significant reduction in the FWHM, both on-axis and off-axis for HVPE GaN are compared with the MOVPE template. The decrease of the FWHM of E2 （high） Raman scat tering spectra further indicates the improvement of crystal quality after HVPE. By comparing the results of secondary- ion-mass spectroscope and photoluminescence spectrum of the samples grown by HVPE and MOVPE, we propose that C-involved defects are originally responsible for the yellow luminescence.

Logic and Path of Combining.Domestic Demand Expansion with Deepening of Supply-Side'Structural Reform

The fifth plenary session of the 19th Central Committee of the Communist Party of China(CPC)puts forward the organic combination of the implementation of the domestic demand expansion strategy with the deepening of supply-side structural reform,and scientifically reveals the internal logic of this organic combination and the realization paths,which is of great significance to the implementation of the new development concept and the constructionof a newdevelopment pattern.First,this paper provides a theoretical explanation for the organic combination of the domestic demand expansion strategy with the supplyside structural reform by analyzing why the traditional policies for expanding domestic demand are ineffective in the new development stage of China.Second,this paper elaborates the internal logic of this organic combination from two aspects.(1)The base point of the domestic demandexpansion strategy must be placed under the main line of the supply-side structural reform.(2)The two should be interconnected and are mutually reinforcing,so as to form a higher level of dynamic equilibrium in which the demand leads the supply and the supply creates the demand.Third,this paper analyzes the huge space for the organic combination of the domestic demand expansion strategy with the supply-side structural reform from the perspective of releasingconsumption potential and creating new demand,and on that basis proposes the realization paths of their organic combination.
