The design method of quadratic orthogonal ratation regression has been applied in the present experiment to study the relationship between soybean yield and the primary factors of soybean cultivation : density, nitrogen fertilizer (carbamide), phosphorus (threefold calcium superphosphate), and potassium (potassium sulphate). The yield function model of the soybean cultivar "Heihe 54", which adapted in the fourth accumulate temperature zone of Heilongjiang province, applied with integrated agricultural measures has been set up in the present Study. Analyzing the primary composition, the effect rank of these cultivation factors on yield has been determined as follow : density > carbamide>threefold calcium suporphosphate>potassium sulphate. The boundary yield analysis conducted in this study may provide the economical benefic of various factors. Through the frequency analysis, the integrated agricultural measures for obtaining the yield of 260 jin/mu are : density : 43.5-44.6 plants/m2; the dosage of carbamide : 4.9-5.1 jin, ma and threefold calcium superphosphate 8.6-8.8 jin/mu. Since the frequency distribution of potassium sulphate is disperse, it indicates that potassium fertilizer is ineffective in this region.

This paper deals with the production and distribution of kenaf in China. Kenaf is being considered to be of great value as a fibrous raw material for pulp and paper making. Seven species of kenaf considered to be most suitable for pulp and papermaking were sieened from more than 80 species. Experimentations on the sowing harvesting, cultivation density and N/P/K ratio revealed that all these factors had significant influence on the growth of the dry stem, the [bast fibers and their lengths. The development of a HB-500 ribboning machine had offered an important implementation for the machanization of kenaf fields to serve as bases to supply bast fibers for the pulp and paper industry.
