The reasonable dense planting is that the density is proper and the row spacing is reasonable when crops or trees are planted in a unit area. Generally expressed as plants per acre (or hole). The reasonable dense planting is an important measure for increasing the yield of the crops, and the relationship between individuals and groups in a unit area of the plants is adjusted to ensure that the individuals grow healthily and the groups grow coordinately, thereby achieving the aim of high yield. Reasonable close planting is favorable for fully utilizing light energy and improving the photosynthetic efficiency. The planting is too dense, the plant leaves are mutually covered, only the upper leaves carry out photosynthesis, the planting is too thin, partial light energy cannot be utilized, and the light energy utilization rate is low. Only reasonable close planting is the most economical practice.

In the actual sowing process, the embodiment selects the land blocks which have flat terrain, deep plough layer and high soil fertility and are ploughed in autumn or harrowed for deep loosening and soil preparation, and does not need continuous cropping or stubble-cutting. The reasonable ploughing and fine soil preparation are one of the fundamental measures for increasing the yield of the soybean, can reduce the harm of diseases and insects, eliminate weeds, store water, preserve soil moisture and mature soil, and are the basis for the full seedling and the strong seedling of the soybean. The soil can be planted in parallel and in a narrow row and densely, and the shoveling is carried out at a proper time in the growth period, so that the capabilities of resisting drought, waterlogging and heating of the soil can be effectively improved. If a land block without a deep scarification and deep ploughing foundation is encountered, ploughing is tried to be harrowing deep scarification or ploughing in autumn with 18-20 cm to create good soil ploughing layer conditions, so that the soil is finely crushed, the ploughing layer depth is increased, and the ground surface is flat.

The sowing mode that can be realized in the practical use of the present invention will be described with reference to fig. 13 to 30. The principle is as follows: according to the invention, the distance between two seedling belts can be controlled between 8cm and 20cm by adjusting two groups of symmetrical ditching discs in the double-belt sowing monomer; the distance between the units on each seedling belt can be between 3cm and 90cm by adjusting the hole number of the seed sowing plate and the speed change mechanism in the transmission system; the synchronous and staggered arrangement of the sowing units on the two sowing belts can be realized by adjusting the axial angles of the two sowing disks in the same sowing device. The distance between each unit on each seedling belt is limited according to the number of plants in the unit and the growth space of crops, and the space required by the growth of the crops is lost due to the excessively small distance, so that the crops compete for light, snatch fertilizer and snatch water; too large space will waste cultivated land, and reduce the utilization rate of water, fertilizer and light. The embodiment can select the most suitable sowing mode of the medium crop according to different actual conditions of the crop. Can really realize the multifunctional use of the same seeder.
