Abstract:

To clarify the high yield of strip intercropping of fresh corn and fresh soybean in Southwest China and to realize efficient field configuration technology for mechanization, two fresh corn varieties with large plant height differences were used as the materials, and two factor split zone design was adopted. The effects of two kinds of bandwidth (high-yield bandwidth 2 m and high-efficiency bandwidth suitable for mechanization 2.4 m) and maize planting density (37,500, 45,000, 52,500, and 60,000 plants hm-2) on population yield, commodity quality, and planting benefit in the strip intercropping system of fresh corn and soybean were comprehensively analyzed, and the optimal field configuration of high-yield and high-efficiency was determined. The results showed that the yield of fresh corn and fresh soybean were more affected by corn planting density and bandwidth, respectively. With the increase of bandwidth, the first-class ear rate of dwarf maize varieties decreased by 25.78%, the bald tip length increased by 9.55%, and the first-class ear rate of tall maize varieties decreased by 11.76% and the bald tip length increased by 17.54%. With the increase of maize density, the first-class ear rate, bald tip length of dwarf, and tall maize varieties decreased significantly under the two bandwidth, and the planting density of dwarf and tall maize increased from 52,500 plants hm-2 to 60,000 plants hm-2 in 2019. The first-class ear rate decreased by 46.16% and 27.78%, the bald tip length increased by 19.44% and 14.17%, and the first-class ear rate decreased by 25.01% and 23.60% under the 2.4 m bandwidth, and the bald tip length increased by 16.46% and 11.53%, respectively. The effects of bandwidth and density on the 2-pod rate and 3-pod rate of fresh soybean reached a significant level. With the increase of bandwidth, the 2-pod rate and 3-pod rate of strip intercropping soybean increased significantly. The 2-pod rate and 3-pod rate of soybean intercropped with dwarf and high stalk maize varieties increased by 7.94% and 18.88%, 8.10% and 16.71%, respectively. With the increase of corn density, the 2-pod rate and 3-pod rate of soybean decreased significantly. In 2019, the corn density increased from 52,500 plants hm-2 to 60,000 plants hm-2. The 2-pod rate of soybean intercropped with high stalk corn decreased by 6.19%-9.09%, and the 3-pod rate decreased by 11.94%-14.39%. The comprehensive evaluation score of principal component and DTOPSIS method showed that under the high-yield and high-efficiency bandwidth, the corn density of 52,500 plants hm-2 and 45,000 plants hm-2 of strip intercropping fresh soybean of dwarf and tall maize varieties were close to the ideal value of maize density, the comprehensive characters performance was good. The planting benefits could reach 84,400 Yuan hm-2 and 100,900 Yuan hm-2, respectively.
