一、前言为了探索小麦亩产900—1000斤的高产规律和进一步明确实现高产稳产的关键性技术措施,于1976—1980年在偃师县本校农场连续进行了小麦高产规律及栽培技术的研究。四年来,气候因素的特点虽然有所不同,但每年均有4一5亩试验田单产达到900斤以上。1977年5.7亩平均单产929.6斤,1978年5.65亩平均单产为966.2斤,1979年5.6亩平均单产900斤,1980年4亩平均单产906.5斤;其中1978年1.13亩平均单产1030斤。围绕高产试验调查测定了高产群体结构,并设置品种、密度、播期、种植方式及促控管理等辅助试验。现将所获资料和初步认识整理分析如下。
I. INTRODUCTION In order to explore the high-yielding law of 900-1000 kg of wheat per mu and further clarify the key technical measures to achieve high and stable yield, a study was conducted on the law of high-yield wheat and cultivation techniques in the university’s farms in Yanshi County from 1976 to 1980. Although the characteristics of climatic factors have been different for the past four years, yields of more than 900 kilograms have been achieved in 4 or 5 mu of experimental fields each year. In 1977, the average yield of 5.7 mu was 929.6 kg. In 1978, the average yield of 5.65 mu was 966.2 kg. In 1979, the average yield of 5.6 mu was 900 kg. In 1980, the average yield of 4 mu was 906.5 kg. In 1978, the average yield of 1.13 mu was 1030 kg. The high-yield population structure was determined around the high-yield test and the auxiliary tests such as variety, density, sowing date, planting mode and promoting control and management were set up. Now the information obtained and preliminary understanding of finishing analysis is as follows.
