A method for reducing and controlling non-point source pollution in a cherry blossom nursery

Abstract

The invention discloses a method for reducing and controlling non-point source pollution in a cherry blossom nursery. The method realizes the reduction and control of non-point source pollution in the cherry blossom nursery by interplanting fresh broad beans and purple sweet potato every year in the cherry blossom nursery; that is, by sowing broad beans, cultivating Broad beans, harvesting broad beans, pressing broad bean plants, sowing purple sweet potato, turning purple sweet potato and cherry blossom nursery management, etc., using broad beans and purple sweet potato have the property of nitrogen fixation, which can increase the nitrogen content in the soil and reduce the amount of nitrogen applied in the nursery; Using broad bean and purple sweet potato plants to return to the field can increase soil organic matter content and improve soil physical and chemical properties; use broad bean and purple sweet potato plants to reduce rainfall interception, infiltration, retention and utilization performance, and reduce nursery soil erosion; compared with conventional management, this method can reduce The amount of chemical nitrogen used in the nursery is 40%, which increases the income of the nursery, improves the organic matter in the soil, effectively controls soil loss and nitrogen transferable nutrients, reduces non-point source pollution, and enables the sustainable and healthy development of the cherry blossom nursery.

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...
