【摘要】 对山西中部半干旱区春播大豆高产模式化栽培技术进行了研究,初步建立以高产为核心的生产函数模型,制定了定量化高产栽培技术调控方案.分析了单因素和二因素产量效应.5个主要因素对产量作用大小是:品种生育期>氮肥施用量>栽培密度>磷肥施用量>地膜覆盖度.模型中全部二因素交互作用共10项,其中达显著水平有5项:栽培密度与氮肥施用量,栽培密度与品种生育期,栽培密度与磷肥施用量,栽培密度与地膜覆盖度,地膜覆盖度与磷肥施用量.

【Abstract】 The patternized cultivation techniques for the high yield of spring sown soybeans in the semi-arid region of Middle Shanxi Province were studied. A functional model for production centered on high yield was preliminarily established, and a program for controlling quantitative high-yielding cultivation techniques was made. Effects of single facfor and two factors on yield were analyzed. The effects of 5 main factors on yield were as follows (in order of importance), development period of variety>application rate of N fertilizer>planting density>application rate of P fertilizer >coverage of film mulching. In the model,there were 10 items showing the interaction of 2 factors, among which 5 reached the significant level, i.e. planting density and N application rate,plantig density and varietal development period, planting density and P application rate,planting density and film mulching coverage,film mulching coverage and P application rate.
