Studies on the efficient use of nutrients in maize/soybean intercropping

By cultivated in pot,the roots shape characteristic,roots vigor,effective nutrient content in root border soil and nutrient high-efficient utilizing mechanism were studied in maize and soybean intercropping condition.The results indicated that under the intercropping condition,maize biological output and economical output increased by 38.73% and 23.4% than those of single maize cultivation.Under the intercropping condition,the roots shape characteristic,roots vigor,effective nutrient content in root border soil were higher than those of single maize cultivation.The soil bacterium,fungi quantity,soil urease and phosphatase increased 2.3 times,94.58%,53.38%,22.45% respectively than those of single maize cultivation,which were helpful for the complicated nitrogen phosphorus compound in the soil turning into can-given inorganic compound and accelerated degradation and transformation of the nitrogen phosphorus compound,improved the effective nutrient content in root border soil.The whole intercropping system had obvious advantage of the biological and economical output.
