| description | The invention relates to a yield measuring method suitable for alfalfa test plots in the saline-alkali dry land. The method comprises steps of 1, setting plot areas, and setting the area of each plotto be more than or equal to 30m ; 2, measuring and calculating the single-row seeding quantity of the plot, and ensuring that the seeding quantity is relatively uniform; 3, selecting sample points;4, sampling method and data determination; 6, measuring and calculating the fresh grass acre yield corresponding to each sample point; 7, sampling at each sampling point, and calculating the dry matter content according to a formula; and 8, measuring and calculating the hay yield according to the dry matter content and the fresh hay yield of each sample point, and multiplying the theoretical yieldby the alfalfa coverage to obtain the actual yield. The method is advantaged in that on the basis of an original method and a scientific theory, the yield measuring method is improved, so the yield measuring method is more targe |
