1986～1988年在全省大豆产区广泛布点进行田间试验,辅以盆钵试验.结果表明,黑土地区大豆施肥最佳N:P_2O_5为1:2,较磷酸二铵N:P_2O_5=1:2.6的效果要好.亩施有效养分6公斤,增产大豆20～30公斤,每公斤有效养分增产大豆5公斤左右.配施微量元素肥料后,每亩再增产大豆12公斤,效益显著.本试验为化肥厂生产大豆专用肥提供了技术配方.
The results showed that the best N: P_2O_5 was 1: 2 for soybean fertilization in black soil region compared with 1: 2.6 for N: P_2O_5 = 1: 2.6 in the soybeans producing area in 1986 ~ 1988 The effect is better.Mu Shi effective nutrient 6 kg, soybean yield 20 to 30 kg, 5 kg of effective nutrients per kilogram of soybean yield.With the application of trace elemental fertilizer, and then increase yield of soybean 12 kg per acre, significant benefit.This experiment for the fertilizer Plant production of soybean fertilizer provides a technical formula.
