The invention discloses a planting method for interplanting pearl plums. The method comprises the steps of land selection and preparation; planting:
transplanting pearl plums: taking pearl plum seedlings in winter, digging planting holes, applying pearl plum base
fertilizer to the bottoms of the planting holes, and
transplanting the pearl plum seedlings to the planting holes; ginger seeds are sowed, ginger blocks containing robust buds are broken off, the sections are covered with
plant ash, the ginger seeds are obtained, a
ridge is formed between two pearl plum plants in the same row in spring, a plurality of planting furrows are formed in the
ridge platform, ginger seed base
fertilizer is applied in the planting furrows, and the ginger seeds are sowed in the planting furrows;
oxalis corniculata is sown, wherein
oxalis corniculata seeds are evenly sown in the soil outside the ridges in spring; management: water and
fertilizer management, ginger harvesting, pearl plum shaping and
pruning, and
pest control. Compared with the prior art, the method has the advantages that the pearl plums are interplanted with the fresh ginger and the
oxalis corniculata which are high in fine root turnover rate, and specific management is applied, so that the C / N ratio of soil is adjusted, soil
nutrient imbalance is improved, soil
microorganism growth is promoted, and high-
fertility bacterial type soil is established.
