Method for improving grassland productivity on basis of livestock-poultry-pasture coupling mode

Abstract

The invention relates to a method for improving grassland productivity on the basis of a livestock-poultry-pasture coupling mode. The method includes the following steps that deteriorated grassland with the vegetation coverage degree not higher than 50% or grassland with the grasshopper density being 10 grasshoppers per square meter or above is selected for stocking, and it is required that the height of a plant community is smaller than 30 cm to guarantee that poultry can see poultry houses; the stocking density and the scale of the poultry and distribution positions of the poultry houses are determined according to the use area of the selected grassland and the poultry raising aim, and the distance between the poultry houses are adjusted according to the determined stocking density of the poultry; after young poultry are subjected to heat supplication stopping and then freely raised on the selected grassland by means of the poultry houses, sufficiency drinking water supply is guaranteed in the daytime, and feed is supplemented at night; the poultry houses are moved every 1-2 months according to vegetation conditions and soil conditions of grazing pasture, and accumulated faeces are evenly scattered around the poultry houses; poultry eggs and poultry products are harvested; after the stocking period of the poultry ends, added forage is harvested and / or cattle and sheep are grazed.

Description

technical field [0001] The invention relates to a method for controlling grassland ecological environment, in particular to a method for improving grassland productivity based on livestock, poultry and grass coupling. Background technique [0002] The grassland area in northern my country is 4 billion mu. Due to continuous years of overloading and grazing, it has caused varying degrees of degradation, induced sandstorms, pests and rodents and other ecological problems, directly affecting the performance of its ecological service functions, and affecting the ecological environment of surrounding areas. quality, and bring harm to the local economic and social development. [0003] Grazing cattle and sheep has always been regarded as the main production function of grassland. The main cause of grassland ecological degradation is overloaded grazing. As long as the grazing pressure is reduced, most degraded grasslands can be restored under the action of natural forces. However, a...

Problems solved by technology

However, although a series of policy measures such as enclosing and prohibiting grazing, ecological migration, and returning grazing to grassland can restore the ecological function of the sandy land, on the premise that there is no alternative industry, the promotion of reducing livestock or prohibiting grazing in pastoral areas has harmed farmers and herdsmen. economic benefits, and therefore are often resisted by farmers and herdsmen
