为了经济合理地使用碳酸氢铵(以下简称碳铵),我们进行了碳铵长效肥对小麦、玉米的肥效试验。试验使用的碳铵长效肥,是把普通碳铵经过造粒、钙镁磷肥包膜和石蜡沥青封面几道工序制成重约1克左右的缓效性颗粒肥。试验布置在渭河滩地冲积性的砂壤土上(pH值8.8),地下水位通常在1米左右。试验的各处理均施磷肥50斤作基肥。普通碳铵和碳铵长效肥的用量按每亩施纯氮10斤计算。小麦试验,肥料均在播种时开沟一次施入,
In order to use ammonium bicarbonate economically and rationally (hereinafter referred to as ammonium bicarbonate), we conducted the ammonium bicarbonate fertilizer on wheat, corn fertilizer test. Ammonium bicarbonate test used in the test, is to ordinary ammonium bicarbonate granulation, calcium magnesium phosphate coating and paraffin wax cover several processes made of about 1 gram of slow-release fertilizer. The experiment is arranged on the alluvial sandy loam soil (pH value of 8.8) in the Weihe River floodplain. The groundwater level is usually about 1 meter. All treatments were applied phosphate fertilizer 50 pounds as a base fertilizer. Ordinary ammonium bicarbonate and ammonium bicarbonate dosage of fertilizer per acre nitrogen 10 kg basis. Wheat test, fertilizers are dug in the sowing once applied,
