The seed purity reflects the percentage of seeds that genetically truly belong to this species to the total number of seeds. The traditional method of testing seed purity is carried out using the field test method. However, this test method takes a relatively long time, but now it is generally used the analysis of the chemical composition of the seed. This kind of analysis method is fast and accurate. The level of purity directly affects the yield of crops. Using wheat as an experiment, the following conclusions are drawn by using a seed counting instrument to measure the weight of future seeds of different purity seeds:
purity
%
g
Kg/hm2
What degree of influence will seed purity have on crops? It can be seen from the table above that the yield of wheat with high seed purity is higher, the lower the seed purity, the lower the crop's future yield is, so in order to increase the yield of the crop, it can be operated by increasing the purity of the seed.
