套种和间种作物的单位面积产量应该为一年内每一亩地里生产出两种或几种农作物产量的总和。例如有20亩地为2∶2,2变5玉米春小麦间作,夏收时,共产小麦6,000斤,平均亩产300斤;秋收时共收玉米15,000斤,平均亩产750斤,合计亩产为1,050斤。又例如20亩地为玉米冬小麦2∶8,8变16宽档间作,小麦收后复栽杂交高粱,这20亩地,共产小麦8,000斤,玉米8,000斤,高粱9,600斤,共收粮食25,600斤,平均亩产1,280斤。
The yield per unit area for intercropping and intercropping should be the sum of the production of two or more crops per acre per year for a year. For example, there are 20 acres of land for the 2: 2, 2 to 5 maize spring wheat intercropping, summer harvest, 6,000 pounds of wheat, an average of 300 kg per mu; autumn harvest received 15,000 pounds of corn, an average of 750 kg per mu, a total of 1,050 acres jin. Another example is 20 acres of maize winter wheat 2: 8,8 change 16 wide stalls for intercropping, wheat after the harvest planted hybrid sorghum, which 20 acres of land, 8,000 kg of wheat, 8,000 kg of corn, sorghum 9,600 pounds, received a total of 25,600 pounds of grain , An average of 1,280 pounds per mu.
