Influence of applied nitrogen during different periods on matter production and distribution of rice colony;

Effects of free-air CO_2 enrichment (FACE) on dry matter production and allocation in wheat;

Effects of phosphorus application on dry matter production and phosphorus uptake in wheat (Triticum aestivum L.);

Study on the effect of K fertilizer application on dry matter production and main yield components of maize

Two rice varieties with ditferent panicle type,Liaojing 326 and Aoyu316,were selected to study their differences under the same culture condition in the biomass production and their distribution,colony growth rate(CGR),net assimilate rate(NAR)and oter important index which were closely related to biomass production such as chlorophyll content,index of leaf area(LAI)and leaf weight per unit area.

Effect of nitrogen rate on matter production and nitrogen metabolism traits of cytoplasmic male sterility maize(Zea mays L.)

For researching matter production and the reason of high yield,using high yield local varieties Jiyugeng,Changbai 9,Tengxi138,dry matter production and yield constitution factors were researched.

The highly effective LAI and adjusted photosynthetic potential, total sink capacity, grade of filled grain, ratio of APP to sink,dry matter production and grain yield were analyzed.

The law of artistic production and material production;

Marx,in the introduction of Introduction to the Political Economy,put forward the theory of unbalance of material production and artistic production with explanations about unbalance.

The study of material production by Karl Marx is from both the material and social dimensions,which includes not only the three levels of connotations of productive forces,productive relations,and individual development,but also the three relationships of man with nature,man with man,and man with himself,thus the concept is rich with human,social,economic,and ecological values.
