Abstract

The invention provides a non-point source pollution prevention and control cultivation method for an osmanthus fragrans nursery garden. The method includes the steps that soil preparation and fertilization are conducted, osmanthus fragrans interlacing planting is conducted, oxalis corniculata is planted between every two rows of osmanthus fragranss, cradling is conducted on the oxalis corniculata according to a certain method, the cradled oxalis corniculata covers the periphery of the trunk of the osmanthus fragrans, nursery garden fertilization is conducted, irrigation and drainage, plant diseases and insect pest prevention and treatment and trimming are conducted according to a normal osmanthus fragrans cultivation method, and the on-point source pollution prevention and control cultivation of the osmanthus fragrans nursery garden is finished. According to the method, a three-dimensional cultivation method that the oxalis corniculata is planted in the osmanthus fragrans nursery garden in an interplanting mode is adopted, the soil structure of the osmanthus fragrans nursery garden can be changed effectively, the N, P and water and soil loss can be reduced, the soil organic matter and nutrient content can be increased effectively, the nursery garden soil carbon pool cultivation cycle is shortened, the ecological diversity of the nursery garden is increased, the pollution to the environment is reduced, the ecological environment of the nursery garden is improved, and operation is easy.

Description

technical field [0001] The invention relates to a plant cultivation method, in particular to a non-point source pollution prevention and control cultivation method for sweet-scented osmanthus nurseries, and belongs to the technical field of agriculture and forestry cultivation. Background technique [0002] my country vigorously promotes ecological construction and urban and rural afforestation, accelerates the development of green seedling industry, and nursery planting has also become an important part of agricultural planting. The new nursery industrial structure will lead to corresponding changes in pollution discharge, pollution forms and characteristics, and the corresponding new industrial structure production technology and pollution control technology are required to guide to reduce and control the non-point source pollution that occurs under this industry. [0003] Osmanthus fragrans is a representative species of Osmanthus genus, one of the top ten famous traditio...
