1981～1986年苏联罗佐夫试验站进行了粒用玉米不同种植比率的十区轮作生产率的研究。轮作中各作物的交替情况如下: 1.秋耕休闲地—冬小麦—粒用玉米—青贮玉米—冬小麦—粒用玉米—青饲玉米—冬小麦—大麦—向日葵。禾谷类作物种植比率为60％,而粒用玉米的种植比率为20％。
From 1981 to 1986, the Russian Rozoff Experimental Station conducted a study on the productivity of grain-ten-crop rotation with different corn planting rates. Crop rotation alternates as follows: 1. Autumn fallow - winter wheat - grain corn - silage corn - winter wheat - grain corn - green forage corn - winter wheat - barley - sunflower. Crops for cereals are 60%, while corn for corn is 20%.
