Planting method for increasing soybean yield

The invention relates to a planting method for increasing soybean yield. The method comprises the following steps of: adopting an under-film drip irrigation wide-narrow row planting mode and a dry sowing and wet emergence mode to emerge seedlings, reasonably increasing planting density, and inhibiting vegetative growth of soybeans in a key period through a comprehensive control technology of irrigation amount and paclobutrazol and mepiquat chloride control agent before the full-bloom stage of the soybeans, enhancing reproductive growth, dwarfing the plants, preventing lodging, improving the photosynthetic efficiency of the plants and increasing the effective harvesting number of the soybeans; determining the total irrigation amount and the fertilization amount in the growth process of the soybeans according to a soil testing formula and the water demand and fertilizer demand ratio in the key period of the soybeans; and applying a water and fertilizer integrated technology, dripping fertilizer and water in sta
