Crop direct sowing culture method and structure

The invention discloses a crop direct sowing culture method and structure. Moist soil is selected from near a field where plants are to be planted; the moist soil is extruded into a cultivating cup in a cup shape by extruding equipment; nutrient matrix and seeds are placed in the cultivating cup, so seed nursing in the cultivating cup is finished; a well pit cultivating hole is formed in a ridge body at certain intervals; the cultivating cup filled with soil and seeds is placed in the well pit cultivating hole; a gap between the inner wall of the well pit cultivating hole and the outer wall of the cultivating cup is backfilled by fine soil; the cultivating cup is watered until water is spilled; and at last, plastic film is paved on the ridge body. In the primary period of spot planting, the crop seeds are placed in the cultivating cup manufactured by the soil; the cup formed by the extruding equipment can prevent nutrient matrix nutrient and moisture from losing, so primary growth of the crop seeds is guaranteed; natural leakage is achieved if much moisture exists; the humidity of the matrix surrounding the seeds can be adjusted; the cultivating cup is placed in the well pit cultivating hole and covered with the plastic film; the structure is similar to an independent greenhouse; and seed sprouting and growth environment is further optimized and crop direct sowing success rate is improved.
