dc.description Based on the optimum control theory (1) , integrative effect of 11 controllable factors of soybean field on soybean aphid (Aphis glycines Matsumura), natural enemies and summer soybean yield was studied systematically by the approaching optimum point and Orthogonal design L27 (3)13 from 1993 to 1996. According to the criterion of not only good control of the pest and increase of soybean yield but also protection of natural enemies, the controllable factors were evaluated synthetically and optimum system control of soybean aphid was suggested as follows: soybean sown in the same maize hole (4 soybean plants to 1 maize plant) or soybean interplanted in maize field (9 rows of soybeans to 2 rows of maize), cultivar Lusoybean 4, sowing time about 10 June, dressing seeds with trace fertilizer at 1800 g/ha, dosage of fertilizer N, P2O5 and K2O application at 45, 60 and 150 kg/ha, dosage of solid manure application at 22500 kg/ha, control soybean aphid with Pirmicarb at 60 g/ha. The technologies of optimum control of soybean aphid were made up in the three different modes including soybean sown in the same maize hole, soybean interplanted in maize field and monoculture soybean. It was demonstrated that the results of control to soybean aphid were 93.5%, 83.9% and 71.8%, soybean growth rates were 28.1%, 16% and 15.3%, respectively, densities of natural enemy in the two interplanting modes were as much treble as that of the control.
