1991年,在总结前两年经验的基础上,我们在辽阳县下八会乡农技站试验地上种植6亩三株同穴玉米高产试验田,采用高密度（理论株数每亩5360株）、地膜覆盖、矮化栽培,以及其他综合高产措施,实现了“吨粮田”。秋后经省、市、县联合验收,亩实收穗数5892穗,平均穗粒数604.8粒,百粒重34克,理论产量1211.6公斤,扣除12％损耗,合亩产1066.2公斤,创造了高寒山区玉米亩产新纪录。我们的主要做法是:
In 1991, on the basis of summing up the experience of the previous two years, we planted 6 mu of three high-yielding experimental fields of syngematic corn on the experimental site of Xiazhuihui Agricultural Technology Station in Liaoyang County, using high density (theoretical number of plants per acre of 5360) Covering, dwarfing cultivation, and other comprehensive high-yielding measures to achieve “tons of grain.” After the fall of the provinces, municipalities and counties joint inspection, the number of ear harvest 5892 acres per acre, the average number of grains per spike 604.8, 100 grain weight 34 grams, the theoretical yield of 1211.6 kg, 12% loss deducted, yield 1066.2 kg per mu, creating New record of mu yield in the alpine mountainous area. Our main approach is:
