This will increase consumer trust and satisfaction with the agricultural product, improving the market competitiveness of the agricultural product.
Example 2: this example is an illustration made in example 1, specifically, the growth factor CZxs is obtained by the following formula:

In this embodiment, according to the set weight coefficient and adjusting the weight coefficients α, β, γ, farmers can quantitatively reflect the extent of influence of different factors on the growth of agricultural products according to the specific growth coefficient CZxs result and the characteristics and importance of specific agricultural products. This will allow the growth factor CZxs to more accurately assess the growth of the agricultural product, knowing the importance of different factors to the growth of the agricultural product to better guide fertilization, irrigation and management. The setting of the weight coefficient enables farmers to pay priority to factors which have important influence on the growth of agricultural products, so that more accurate growth guidance is realized.
