摘要:
采用4因素5水平旋转回归正交组合设计,研究了江淮地区小麦播期、密度、氮、磷肥4因素的综合效应,并建立以籽粒产量、蛋白质含量为目标函数的数学模型,通过计算机模拟寻优,筛选出小麦品种肖农12,亩产350公斤,籽粒蛋白质含量12%,较经济的综合农艺措施为:10月20—23日播种;基本苗15—16万/亩;施纯氮11.8—13.3公斤/亩;五氧化二磷5.4—7.3公斤/亩。

A STUDY ON THE MATHEMATICAL MODEL OF COMPREHENSIVE FARMING MEASURES FOR HIGH OUTPUT AND GOOD QUALITY GRAINS OF WHEAT
()
Abstract:
This paper deals with the study on the synthetical effect of 4 factors (seeding date, density, N-fertilizer and P-fertilizer) in Jiang Huai Arae by applying the design of the 4 factors and 5 levels rotational regression orthogonal combination. Based on the data of a field experiment, mathematical modelings about the relationship between. 4 cultivating measures and grain yield as well as protein content were set up By computer simulation, economical comprehensive farming measures for the 350 kg yield per mu and 12% protein content were chosen with the cultivar "Xiao Nong 12" to be seeding date from 20th to 23rd October; density at 150 to 160 thousand per mu; amount of N-fertilizer and P-fertilizer at 11.8 to 13.3 kg Per mu and 5.4 to 7.3 kg per mu, respectively.
Key words:  High yield,Good quality,Comprehensive farming measures,Mathematical model,Computer simulating selection.
