A: The walnut tree fertilization methods include radial fertilization, circular fertilization, and foliar spray fertilization. The specific practice of radial fertilization is to dig 4 to 8 radial fertilization furrows in the direction of the trunk starting from different positions on the edge of the crown of a walnut tree. The length of the furrow depends on the size of the crown and the type of fertilization. The circular fertilization method is: around the trunk, along the outer edge of the crown, dig a circular fertilization ditch 30 to 40 cm deep and 40 to 50 cm wide, and fertilize the fertilizer evenly and bury it well. Foliar spray fertilizer is a kind of economic and effective fertilization method, which has the advantages of less fertilizer, quick effect, high utilization rate and can be sprayed with a variety of pesticides, etc., and is particularly useful in the areas of water shortage and fertilizer. 2023 New Laser Distance Sensor
