Embodiment 1
[0028] A method for planting walnuts rich in multiple trace elements, comprising the following steps:
[0029] (1) Site selection and site preparation: select fertile, well-drained, sunny flats or hillsides as planting sites, dig 80 cm deep pits as planting holes, and plant row spacing is 6×10 meters, and spread a layer of straw in the planting holes , crushed soil, and poured dung water on the surface, and finally spread a film to ferment for 7 days;
[0030] (2) Field planting: transplant the walnut saplings after two years of grafting into the planting hole, and dig a fertilization ring at 10 cm of the planting hole, with a depth of 8 cm; and apply base fertilizer, spray water and cover the surface with stalks;
[0031] (3) Fertilizer and water management: when the seedling germination height reaches 10cm, pour 5kg of urea water per plant; when the seedling germination height reaches 20cm, each plant sprays 5L nutrient solution; after the "frost", dig a hole in the same dir...
