为了探索粮棉间作双高产的途径,我们对玉米、元麦、棉花间作进行了两年试验。1976年试验地二亩,元麦总产270斤,折亩产403斤;玉米总产724斤,折亩产1080斤;棉花总产皮棉174斤,折亩产130.8斤。1977年试验分一行玉米四行棉花和二行玉米四行棉花二个处理。一行玉米四行棉花的,元麦折亩产258斤;玉米折亩产727.8斤;皮棉折亩产141.4斤,比对照田亩产98.7斤增产43.3％。二行玉米四行棉花的,元麦折亩产258斤;玉米折亩产1060.2斤;皮棉折亩产115.5斤,比对照田亩产91.3斤增产26.5％。
In order to explore the way of double cropping between grain and cotton, we conducted a two-year experiment on the intercropping of maize, wheat and cotton. Experimental area of two acres in 1976, the total yield of 270 tons of wheat, yielding 403 kg per mu; corn total output of 724 kg, yielding muster 1080 kg; cotton lint 174 kg, yield 130.8 kg mu yield. In 1977, a pilot line of corn four lines of cotton and two lines of corn two lines of cotton processing. One line of corn four lines of cotton, Yuan Mai fold 258 pounds; corn fold yield 727.8 kg; lint fold 141.4 kg, 98.7 kg more than the control yield 43.3%. Two lines of corn four lines of cotton, Yuanmaishan yield 258 pounds per mu; corn fold 1060.2 pounds; lint cotton yield 115.5 pounds, 91.3 pounds per mu than the control yield 26.5%.
