The invention discloses a method for storing and utilizing
biogas slurry of
livestock and poultry by virtue of winter idle rice fields and a
management system. According to the method,
biogas slurry produced in
biogas tanks are directly stored in or used to irrigate winter idle rice fields after rice harvesting, and after the rice fields is dried, repeated storage or
irrigation is carried out until rice is planted in spring of next year. The method can completely solve the contradiction between
continuous production of the biogas
slurry and periodic
fertilizer requirement of crops by storing the biogas slurry of
livestock and poultry in the idle rice fields in winter, and at the same time, can reduce the difficulty of utilizing the biogas slurry in farmland and improve the enthusiasm of farmers to use the biogas slurry. The
management system provided by the invention exerts the technical advantages of an agricultural technology promotion department, breaks information isolation among the farmers,
livestock and poultry farms, biogas liquid transportation companies and
crop growth information, and comprehensively uniformly synergistically manages utilization of the biogas slurry in farmlands, enables the advantages of utilization of the biogas slurry in farmlands to be optimally achieved, realizes development of a planting-breeding
coupling eco-circulating agricultural model in aregion, and promotes market-oriented promotion and application of utilization of the biogas slurry in farmlands.
