Abstract: Soybean and maize strip composite planting technology can give full play to the nitrogen-fixing effect of soybeans and the marginal effect of maize, realize the matching of good varieties and good methods, the integration of agricultural technology and agriculture, and the organic combination of land and cultivation, effectively solve the problems of low production efficiency, glory, fertilizer and water competition of traditional crop interplanting, and effectively improve agricultural production efficiency. Taking the actual situation of agricultural production in Lingtai County as an example, the technology of soybean and maize strip composite planting was studied in order to provide technical reference for farmers.
