摘要
用深层发酵法生产Ap—2号磷菌肥,于1990年至1992年在黑龙江省进行了田间试验。结果表明,与单施化学磷肥相比使小麦增产18.1%;当代替50—70%化学磷肥时,与对照相比,使玉米分别增产14.27%和12.14%;用于大豆,其增产幅度与施磷菌肥的数量成正相关。当代替50%、70%和100%化学磷肥时,分别比单施化学磷肥增产12.86%、13.32%和14.13%。
Ap-2 phosphobacteria manure were produced with deep fermentation,and field experiment was carried out by using the fertilizer in Heilongjiang provice in 1990 to 1992. The result indictted that the Ap-2 fertilizer increased yield of wheat by 18. 1 % compared to alone chemical phosphate fertiliz er. The Ap-2 fertilizer increaSed yield of maize by 14. 27% and 12. 14%, respectively, when Ap-2fertilizer substitute for 50% and 70% of chemical phosphate fertilizer, compated to contrast. The Ap-2 fertilizer was applied to soybean, the scope of increase production can be appear positive interrelation to the amount of the Ap-2 fertilizer. The Ap-2 fertilizer increased yield by 12. 86%,13. 32% and 14. 13%, respectively, when the fertilizer substitute for 50%, 70% and 100% of chemical phosphate fertilizer, compered to alone chemical phosphate fertilizer.
