Method for reducing and controlling non-point source pollution of oriental cherry nursery

Abstract

The invention discloses a method for reducing and controlling non-point source pollution of an oriental cherry nursery. The method realizes reduction and control of non-point source pollution of a nursery through annual interplanting of fresh-eaten broad beans and Vicia sativa L. in an oriental cherry nursery. Through use of broad bean sowing, broad bean planting, broad bean harvest, broad bean plant turning and pressing, Vicia sativa L. sowing, Vicia sativa L. turning and pressing and oriental cherry nursery management, based on nitrogen fixation properties of broad beans and Vicia sativa L., the nitrogen content in the soil is increased and the nitrogen application rate in the nursery is reduced. Through reuse of broad bean and Vicia sativa L. plants in fields, soil organic matter content is increased and physicochemical properties of soil are improved. Through rainfall interception, infiltration, retention and utilization performances of broad bean and Vicia sativa L. plants, the water and soil loss of a nursery is reduced. Compared with the conventional management method, the method reduces chemical nitrogen use amount by 40%, improves nursery incomes, increases soil organic matter content, effectively controls soil loss and nitrogen transferable nutrients and reduces non-point source pollution so that sustainable development of an oriental cherry nursery is realized.

Description

technical field [0001] The invention relates to a cultivation method for annual interplanting of plants in nurseries to reduce and control non-point source pollution in nurseries, in particular to a cultivation method for annual interplanting of fresh broad beans and purple sweet potato in cherry blossom nurseries to reduce and control non-point source pollution. Background technique [0002] At present, nursery planting is an important part of agricultural planting. The rapid development of the nursery industry has led to new changes in the discharge of nursery non-point source pollution, the form and characteristics of non-point source pollution, and it is necessary to have appropriate production technology and pollution control technology to control it. Guidance to reduce and control non-point source pollution. Scientific name of cherry blossom: Cerasus ssp. is the collective name for several plants of the genus Sakura in the family Rosaceae. In the newly revised name o...
