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.

本试验应用二次回归正交旋转设计试验方法研究了黑河54号大豆主要栽培因子(密度、氮肥、磷肥和钾肥)与大豆产量的关系,建立了数学模型。通过微机对横型的解析,得出各因子对产量效应的主次关系;两因子搭配的产量效应以及等产量线图。通过边际产量分析了经济效益,并且藉助微机模拟试验(频数分析),求出指定产量水平下的最佳农艺措施,为总结大豆栽培经验与指导生产提供了新的思路。

A 3-years(1984~1986) study was conducted to determine the effect of N, P, and K levels on lint yield and quality of cotton (Gossypium hirsutum L. ) . Simulation quadrutive regression models of lint yield and fiber quality were established. Comprehensive agronomic measures for high productivity, quality and lowcost have been worked out. The results from this study showed evident effects of N, P, K. levels on lint yield (P<0.05) , and the regression model was significant ( P<0.001 ) , of which N had the biggest...

A 3-years(1984~1986) study was conducted to determine the effect of N, P, and K levels on lint yield and quality of cotton (Gossypium hirsutum L. ) . Simulation quadrutive regression models of lint yield and fiber quality were established. Comprehensive agronomic measures for high productivity, quality and lowcost have been worked out. The results from this study showed evident effects of N, P, K. levels on lint yield (P<0.05) , and the regression model was significant ( P<0.001 ) , of which N had the biggest effect followed by P and K. N, P, K levels as cultivation factors affect on fiber quality obviously. The effect of N, P, K on fiber length was more sighificant than on fiber strength and fineness Maximum effect of the factors on fiber quality was 50% span length ( P<0.05 ) . The effect of the factors on riber quality was N>K>P.The result indicated no significant relaivity of lint yield and fiber quality ( except for fiber fineness ) . Therefore, lint yield and fiber quality are independent aspects for cultivation.
