本试验就不同肥料用量于三麦的不同生育期分层施肥、分次追肥进行比较,同时设置氮磷的不同配比,试图通过试验,提出相应的施肥方法,促进郊区的粮食生产。一、试验方法与经过 1.试验设计:试验田土质为潮沟干。小区面积0.02亩,随机排列,重复二次。施肥共设13个处理(包括对照),详见表1。 In this experiment, different fertilizers were applied in different growth stages of Sanmai stratified fertilization, topdressing topdressing comparisons, and different proportions of nitrogen and phosphorus were set. At the same time, experiments were put forward to put forward corresponding fertilization methods to promote grain production in the suburbs. First, the test method and after 1. Experimental Design: Experimental soil tidal trough dry. Area of ​​0.02 acres of plot, randomly arranged, repeated twice.
