This article introduces the concept、core technologies of business intelligence and introduced mainly neural network, genetic algorithm used by the article,introduced the architecture of business intelligence,according to the architecture,designed the architecture based on tobacco formula.

Four different application ratio was set,and biological characteristics,yield and intrinsic chemical composition of tobacco were studied to definite the ratio of basic and additional tobacco-specific fertilizer in Liancheng area.

In order to solve the problem of unreasonable distribution route, the tobacco distribution route optimization model was established according to the characteristics of tobacco distribution.

In order to solve the problem of distribution area segmentation of tobacco distribution, an improved K-means clustering algorithm was proposed.

Discussion on technique for formula fertilization and agrochemical service by fertilizer enterprises;

The 3414 test of rice formula fertilization with soil test in percogenic purple mud field has been studied in Dazhou City, the results indicated that, rice yield had a high positive correlation with fertilization amount, the correlation between nitrogen and yield was the best, phosphorus and potassium took second place.

The soil obstacle factor, the critical values of some nutrients and the supply intensity, as well as fertilizer efficiency should be paid more attention in formula fertilization by soil testing.
