Organic cultivation method for gramineous pasture in alpine pastoral areas

Abstract

The invention discloses an organic cultivation method for gramineous pasture in alpine pastoral areas. The organic cultivation method comprises the steps of land selection, soil preparation and fertilizer application, seed selection and planting, filed management, and harvest after maturity; the step of land selection comprises selecting a land parcel with organic certification or an organic certification conversion period, wherein the land parcel is a complete land parcel containing no land parcel of conventional production; the step of soil preparation and fertilizer application comprises uniformly applying a base fertilizer on the ground surface of the selected land parcel, and carrying out soil deep tillage and soil airing on the soil of the land parcel; the step of seed selection andplanting comprises applying a seed fertilizer during a sowing process, and applying the seed fertilizer by using a seed-fertilizer layering sowing machine; and the step of field management comprises applying topdressing before the stem elongation of the pasture, wherein the base fertilizer, the seed fertilizer and the topdressing are selected from farmyard manure, biological organic fertilizers ora combination of the farmyard manure and the biological organic fertilizers, the farmyard manure is prepared by composting and decomposing animal manure, livestock and poultry manure, green manure and straw, and the biological organic fertilizer are approved by a certificate authority.

Description

technical field [0001] The invention relates to the technical field of cultivation of forage grasses in alpine pastoral areas, in particular to an organic cultivation method for gramineous pasture grasses in alpine pastoral areas. Background technique [0002] In recent years, people's awareness of health and environmental protection has been increasing, and the organic animal husbandry with the concept of protecting the ecological environment and producing healthy food has developed rapidly around the world. In the production of organic animal husbandry, forage is the material basis and source of nutrition for the production and development of animal husbandry, and it is also the source of pollution that produces public hazards in animal husbandry. The organic cultivation and management of forage can solve the problem of "environmental branding", and at the same time provide a solid foundation for the certification of organic milk and organic beef and mutton.

Problems solved by technology

In the process of conventional forage production, the ecological environment and forage are polluted to varying degrees through the extensive use of chemical fertilizers and pesticides and other agrochemicals, such as the problem of excessive pesticide residues, the problem of nitrate caused by excessive nitrogen fertilizers, and the soil pollution caused by long-term phosphorus fertilizer application. , water sources and other heavy metals (such as Zn and Cd) pollution, natural ecosystems are destroyed, and land production capacity continues to decline
