NOVELTY - Intercropping cultivation of maize and soybean involves selecting high yield, steady production, disease-resistant, insect-resistant and high-quality maize variety, selecting full uniform size consistent seeds, and soaking seeds in water for 6-12 hours, placing drained seeds in nutrient solution, and soaking for 3-5 minutes, where nutrient solution comprises wine tail, sodium humate, sodium lauroyl sarcosinate, potassium sorbate, allicin, zinc pyrithione, sophorolipids, rice and water.    USE - The method is useful for intercropping cultivation of maize and soybean (claimed).    ADVANTAGE - The method enables intercropping cultivation of maize and soybean by simple process at low cost, with high production efficiency.    DETAILED DESCRIPTION - Intercropping cultivation of maize and soybean, involves selecting high yield, steady production, disease-resistant, insect-resistant and high-quality variety, intercropping or transplanting selected 95-105 days mature varieties, selecting full uniform size consistent seeds, and soaking seeds in 55-57 degrees C water for 6-12 hours, placing drained seeds in nutrient solution, soaking for 3-5 minutes, where nutrient solution comprises 0.3-1 pts. wt. wine tail, 0.6-2 pts. wt. sodium humate, 1-2 pts. wt. sodium lauroyl sarcosinate, 2-3 pts. wt. potassium sorbate, 2-4 pts. wt. allicin, 0.1-0.2 pts. wt. zinc pyrithione, 1-2 pts. wt. sophorolipids, 10-20 pts. wt. rice and 1000-1100 pts. wt. water, and the nutrient solution is prepared by heating cooked rice and cooling to 30-40 degrees C, adding wine tail and allicin, adding 10-20% water, sealing for 3-5 hours, and fermenting liquid, adding sodium lauroyl sarcosinate to 50-60 times water, stirring evenly, adding sodium humate, potassium sorbate, mixing, adding yeast mixture, adding the remaining raw materials and stirring evenly, selecting high yield, high quality, disease-resistant and insect-resistant varieties, setting seed with purity of higher than 98%, and germination rate of higher than 95%, and soaking seed in nutrient solution for 3-5 minutes, where nutrient solution comprises 1-2 pts. wt. sodium dehydroacetate, 1-2 pts. wt. ferrous ammonium sulfate, 0.1-0.2 pts. wt. forchlorfenuron, 0.4-1 pts. wt. alpha-terpineol, 0.1-0.2 pts. wt. dithio salicylic acid and 900-1000 pts. wt. deionized water, removing seeds and drying, cleaning soil, applying 3500-4000 kg farmyard manure, 40-50 kg superphosphate, 20-30 kg urea, 2-3 kg/ mu m chlorpyrifos, ploughing soil, ridging soil with 1.4-1.5 m wide ridge, 0.8-1 m length, 25-30 cm ridge height, planting maize in high ridge with 40-50 cm row spacing of maize, planting soybean in small ridge with row spacing for 23-25 cm, setting 48-50 cm spacing between maize and soybeans, seedling corn according to the requirements of the density of the seedlings with 3 seeds of single grain and 2 seeds of double grain, controlling soy bean seeder for every 3-5 holes, moving left three or four isolated strains after emergence, before seedling performing weeding management with amine chemical liquid spray, laying a mulching film, maintaining corn and soybeans in water for germination, growing seedlings of corn and soybean for 5-7 days, inhibiting the growth of grass to maintain moisture evaporation, performing tillage weeding with high efficiency and applying low toxicity biological pesticide to control the plant diseases and insect pests damage, applying fertilizer, applying nitrogen fertilizers in later flowering stage, spraying foliar fertilizer such as trace elements boron, timely harvesting fresh corn, beard black and seed, , harvesting old soybean in soybean podding stage, and harvesting at ripe stage.
