经土壤普查化验分析,我县酸性、微酸性土壤占73.97％,面积这样大,如何合理制定配方施肥方案呢?我们本着探索的目的,在酸性土(pH5.6)上进行这次小麦施用钼肥的试验。试验设五个处理(拌种、基肥、分蘖期喷施、孕穗期喷施、对照),重复3次,随机区组排列,小区面积0.02亩,每小区用磷肥(过磷酸钙,含五氧化二磷17％)0.8公斤,人畜粪35公斤,尿素0.25斤,磷肥和人畜粪全部作基肥,尿素80％作底肥,20％作追肥,钼肥用钼酸铵,供试品种绵阳15号,收获时采用单打单晒单称重。经试验分析,处理间达显著水准,重复间不显著,多重比较的结果,拌种效果最好,与对照
The soil census laboratory analysis, our county acidic, slightly acidic soil accounted for 73.97%, the area is so large, how to formulate a formula fertilization program? We in the exploration of purpose, in acid soil (pH5.6) for the wheat Molybdenum fertilizer test. The experiment set up five treatments (seed dressing, basal fertilizer, spraying at the tillering stage and spraying at the booting stage, control), repeated 3 times and arranged in random blocks with a plot area of 0.02 mu. Each plot was treated with phosphate fertilizer (superphosphate, Phosphorus, manure and manure all as base fertilizer, urea 80% as base fertilizer, 20% as top dressing, Molybdenum fertilizer with ammonium molybdate, the tested varieties Mianyang 15, Harvest single singles single sun weighing. After the experimental analysis, the treatment room reached a significant level, the repetition was not significant, the results of multiple comparisons, dressing the best, compared with the control
