- Abstract:
-
Based on the construction of evaluation indicators system of the total grain output in Yanchi county, firstly analysis and evaluation to 25 years of total grain production and influence factors in Yanchi county were carried out by applying factor analysis. The 5 main components influence grain yield. Component 1 was decided by the input factor,factor 2 by the light and temperature, factor 3 by the growth factor, factor 4 by the precipitation factor and factor 5 was by wind damage factors. The proportion of each factor was 38.7559%, 17.985 2%, 10.872 8%, 11.888 4%, 10.479 9%, respectively. Yanchi county’s total grain output was mainly depended on the first factor. The overall best assessment happened in 2004, the worst one occurred in 1984. At the same time, the corresponding countermeasures were proposed for the purpose of the current development situation of the total grain output in Yanchi county.
