The nutritional components' trends of Paspalum notatum flugge in it's growing periods are investigated preliminarily.The results show that the contents of the main nutritional components of protein,fat,carbohydrate,Ca and P are very rich in Paspalum notatum flugge.These nutritional components are different in content in different growing periods and change regularly.When Paspalum notatum flugge is in its seedling period,its crude protein makes 15.93% and crude fat makes 5.34%, while the output of fress grass is low.In its fast growing period,the output of fresh grass increases rapidly with high nutrition contents that crude protein is 11.55% and crude fat is 4.67%.It is the best time for fresh forage.The dynamic changing curve of the nutritional components of Paspalum notatum flugge in different growing periods and the modeled regression equation show significant correlation coefficients except calcium;meanwhile the nutritional components are analyzed in order to observe the changes of them and use Paspalum notatum flugge rationally.
