A bioeconomic computer model was constructed to simulate biological and economic inputs and outputs for life cycle swine production. Parameters and relationships used in model were developed and verified by comparison with experimental results in the literature. the bioeconomic model was constructed by several modules such as growth and development, pregnancy, lactation, and replacement gilt etc. the result is: (1) the bioeconomic computer model was efficient way to describe pig production system and research factors' effect and their interactions. (2) Traits in the model were: oestrus traits;mature weight and feed requirements of sows;longevity of sows;litter size;growth rate and daily feed intake of young pigs and fatteners;mortality rate of pigs. (3) Sow longevity is 2.12 years and yearly culling rate is 47.20%. Yearly farrowing sow is 2.08 and total numbers of farrowings per gilt is 4.62. (4) Average litter size total born is 11.23, litter size born alive is 10.40, litter size weaned is 8.80.

the low fertilizer utilization at growing season and environment pollution coursed by unreasonable fertilization are becoming global outstanding problems in agricultural *** and reasonable fertilization based on rapid and nondestructive plant nutrient detection will be a valuable solution for solving above *** this study,spectral transmittance in wavelength ranged from 300 to 1100 nm,chlorophyll content and nitrogen content of rice and cucumber leaves treated with culture solution in five different nitrogen levels were *** to the correlation analysis between them,560,650,and 720 nm as feature wavelengths and 940 nm as reference wavelength were determined for nitrogen *** analysis between 21 spectral feature parameters composed by the transmittance at above wavelength,the leaf chlorophyll content and nitrogen content,and combined withtheir regression examination indicated that spectral feature parameters of(T940- T560) /(T940 + T560),log(T940/T560)and log(T940/T650) are useful to conduct plant nutrient diagnosis with less than8%relative error in rice and cucumber ***,the above spectral feature parameters as plant nitrogen indicators can be used to estimate the chlorophyll content and nitrogen content,furthermore support for non-destructive plant nutrient detection and fertilizer recommendation based on testing soil.
