The invention discloses a method of imitating-wild directional hole-controlled root cultivation under the forest of elaeagnus angustifolia. The method includes the steps of 1), selection of forest land, namely selecting artificial forest land or mountain area with the elevation of 800-1200m, the slope of 30-60 degrees, the shade degree of 30%-70% and the depth of soil layer of more than 50cm, andthe slope facing north and east, with the temperature and humidity suitable for the growth environment of elaeagnus angustifolia; 2), mechanical drilling, namely avoiding rock and tree roots, using amechanical drilling machine on the slope to drill horizontal planting holes, wherein the diameter of the planting holes is controlled at 30-35cm, the depth is 40-50cm, and 1500-2000 holes are drilledper mu; 3), from March to June, filling well-allocated elaeagnus angustifolia culture media into the guide holes, planting 2-3 strong seedlings of elaeagnus angustifolia in the holes 10cm from the mouth, filling and patting with the media, pouring enough rooting water, covering the surface with weeds or withered leaves to moisturize, and performing harvesting after 3-5 years. The technique provided is simple in operation, less in investment, free from manual establishment of shading facilities and irrigation, high in yield, convenient in manual mining and capable of improving economic benefitof growers remarkably.
