Double-dibble-six-plants hole-in-hole type corn planting method

The invention provides a double-dibble-six-plants hole-in-hole type corn planting method, wherein two ridges of conventional corn field are changed into a wide ridge, a shallow trench is linearly dug along the axial center line of the wide ridge, and fertilizer is applied into the shallow trench; bilateral sides of the shallow trench are respectively provided with a row of seeding holes; a elongated fertilizing hole is distantly arranged outside each seeding hole of the two rows of seeding holes which are symmetrically arranged at bilateral sides of the shallow trench; two dibbles are symmetrically arranged inside each seeding hole, and three corn seeds are planted in each dibble, and each seeding hole contains six corn plants. The wide ridge and the shallow trench fertilizing reduce losing water and fertilizer, thus the soil moisture conservation effect is good, drought is resisted and water is saved; the double-hole type plantation makes the root system of corns strong and intertwined, therefore the lodging-resistant ability of corns is strong; three corn plants in one dibble are grown into a cluster which is able to receive the dew at night and store the dew in the roots thereof, thereby reducing the evaporating speed of surface water and being more beneficial to the growth of root system; the light and ventilation between ridges can be maintained after widening the ridges, thus increasing the chance of being pollinated, reducing the breeding of pests, ensuring the sunshine amount of plants, creating the best growing environment for corns, and increasing the yield of corn even more.
