Abstract:

In order to perfect the sweet potato/fresh corn model of cultivation techniques of form a complete set, seek the best corn planting and density. Through the field experiments, the corn planting density and two factors crack zone were designed, researched different maize population of jade/sweet potato mode sweet potato agronomic characters and the influence of the production. The results showed that, the sweet potato/fresh corn mode B1M1 to deal with the highest, and the total output value of 98609.19 yuan/hm2, followed by B1M2, B3M2, the value of 87423.65 yuan/hm2, 82179.4 yuan/hm2 respectively, and the lowest B4M3 processing were high 65.43%, 46.66%, 37.87%. Jade relay itercropping system, corn chips on June 5th to 15th sowing seeds, the density of 15000 plants/hm2 condition conducive to the improvement of total output and output.
