摘  要:
本文对旱作条件下大豆高产栽培综合农艺措施进行了探讨,并通过田间试验测定参数,建立函数模型。使用微机及我所编制的程序,解析了播期(x_1)、密度(x_2)、氮肥(x_3)、磷肥(x_4)、钾肥(x_5)等主要因素间相互效应及与产量的关系,提出了大豆高产栽培最佳综合农艺措施,为旱作条件下大豆高产计划栽培提供了科学依据。

摘  要:
In 1983, the parameter tests were performed in field to establish a mathematic model under the no-irriggation condition. The contributiou order of testing factors to soybean yield is density >sowing date >phosphorous fertilizer >nitrogen fertilizer >potassium fertilizer.Searching for the optimization of the model with the computer, we assume that step is one, five factors and five levels a composed of 3125 designs yield in 618 designs reaches more than 400jin/mu. By frequency analysis, the best agronomic measures can be morked out and are listed below: the plant population is 18000-19000 plants/mu, sowing date is 6-8th of May, phosphate fertilizer is 30-33jin/mu, urea is 6.5jin/ mu, potassium sulphate is 22-24jin/mu.
