一、前言本项研究针对淮北地区的生态特点与生产水平,主要探讨淮北地区小麦亩产300—400公斤优质、低耗配套栽培技术。在“淮北小麦大面积增产途径及栽培技术”和“夏秋粮均衡增产综合栽培技术体系”两课题研究的基础上,进行配套技术组装研究,建立起小麦高产、优质、低耗的栽培技术体系,指导大面积生产夺取丰收。三年来,课题组开展了“施肥量、播种期与种植密度及其互作效应”的配套技术研究,并不失时机地逐步推广应用。为检验和完善配套栽培技术,自1984年秋播起开展了“有机肥与无机肥配施”、“氮磷化肥合理施用”、“密度与施氮量”和“等量氮肥不同运筹方式对小麦生育、产量和品质的影响”四项专题研究。此外,还采用系统工程的原理和方法,运用电子计算机进行模拟寻优,开展了“综合农艺措施数学模型及优化方案”
I. Preface This study aims at the ecological characteristics and production level of Huaibei area, mainly discussing the cultivation techniques of high quality and low consumption of 300-400 kg of wheat in Huaibei area. On the basis of the research on two major issues of “large-area wheat yield-increasing ways and cultivation techniques in Huaibei” and “comprehensive cultivation technology system of balanced grain yield increase in summer and autumn”, the technical package research was carried out to establish the cultivation technology system of high yield, high quality and low consumption of wheat, Guide large-scale production to seize good harvest. In the past three years, the research team carried out the research on the matching technologies of “the amount of fertilizer applied, the sowing date, the planting density and their interaction effects”, and did not lose no time to gradually promote the application. In order to test and improve the matching cultivation techniques, the “Broadcasting of Organic and Inorganic Fertilizers”, “Rational Application of Nitrogen and Phosphorus Fertilizers”, “Density and Nitrogen Application Rate” and “ Fertility, Yield and Quality Impact ”four special studies. In addition, using the principles and methods of system engineering, using computer simulation to optimize, launched the “comprehensive agronomy mathematical model and optimization program”
