Abstract:

The purpose of this paper is to explore the most suitable belt type of soybean corn composite planting in Jalaid Banner area, and analyze the advantages and economic benefits of four models of soybean corn belt composite planting. The belt designs of 2:2 mode, 4:4 mode, 6:4 mode and 4:2 mode of soybean corn belt composite planting had been set up in Wudaohezi Village, Haolibao Town, Jalaid Banner Science and Technology Demonstration Zone from 2019 to 2022. The soybean yield was significantly positively correlated with the number of plants per hectare. Through economic benefit analysis, compared with single planting corn, the 4:4 mode had a maximum income increase of 246.9 yuan per hectare; compared with single soybean, the 4:2 mode had a maximum increase of 11707.65 yuan per hectare in income. From the field performance, the lodging of soybean in 2:2 mode was relatively heavy, which was not suitable for mechanized operation. The 4:4 mode was matched with the existing agricultural machinery, which was conducive to mechanized operation. Various belt types of corn belt did not reach the ideal density, and the density of soybean belt was high, which had a certain impact on the test results. Through comparative analysis, it is concluded that the most suitable soybean corn composite planting mode for promotion in Jalaid Banner is the 4:2 mode.
