Pasture evolution monitoring and forecasting method for cashmere goat breeding

Abstract

The invention relates to the technical field of animal husbandry pasture monitoring method, in particular to a method for monitoring and predicting grassland evolution for cashmere goat breeding, It includes: according to the sampling process of the grassland characteristics, the vegetation characteristics of the sampling points are manually counted and compared with the spectral characteristics obtained from the photographs, and the correlation coordinate map between the spectral characteristics and the actual statistical results of the grassland is obtained after the empirical correction bydistinguishing different regions and seasons; the correlation coordinate map between the spectral characteristics and the actual statistical results of the grassland is obtained. According to the sampling process of cashmere goats, the characteristics of cashmere goats in the sampling area are statistically analyzed and compared with the infrared spectral characteristics obtained from aerial photographs, and the correlation coordinates between the infrared spectral characteristics and the statistical data of cashmere goats are obtained. The invention realizes the monitoring of the grassland characteristics through the sampling of the spectral characteristics, realizes the macroscopic monitoring of the cashmere goat characteristics through the sampling of the daytime infrared spectral characteristics, synthesizes the two monitoring data to obtain the prediction results of the grassland evolution with higher accuracy, and effectively reduces the labor cost and the time delay of the statistics of the cashmere goat characteristics.

Description

Technical field: [0001] The invention relates to the technical field of animal husbandry grassland monitoring methods, in particular to a grassland evolution monitoring and prediction method for cashmere goat breeding. Background technique: [0002] In the process of pasture animal husbandry production, it is necessary to accurately monitor the use of pasture. Underuse of pasture will waste pasture resources and reduce the value of livestock production. Overuse of pasture will cause pasture degradation or even desertification. The cost of follow-up grass planting treatment is high, which directly pushes up Livestock costs. [0003] When raising cashmere goats in pastures, due to the characteristics of grass-eating roots of cashmere goats, it is more difficult to control the evolution of pastures, which puts forward higher requirements for the accuracy of the above monitoring. [0004] At present, aerial photography and satellite photos have been widely used in the monitorin...
