一深:就是深施。最好作基肥深施,这样氨可以被土壤复盖和吸附,同时受气温影响小,可以防止氨的挥发损失,提高肥效的利用率。做法是将碳酸氢铵与磷肥、有机肥、粘土等混合制成球肥,深施在水稻丛间2—3寸的土层中。或者是前作收割后,将碳酸氢铵施于大田表面(可与有机肥混用),随施肥,随翻耕,放水泡田,这样将碳酸氢铵翻入土下。在旱地作物上可以穴施,挖沟条施。
A deep: that is, deep facilities. Best for basal application, so that ammonia can be covered and adsorbed by the soil, while the impact of small temperature, ammonia can prevent the loss of volatility and improve fertilizer efficiency. The practice is to ammonium bicarbonate and phosphate fertilizer, organic fertilizer, clay and other mixed ball made of fertilizer, deep in the 2-3 inches of rice in the soil between the layers. Or before harvesting, the ammonium bicarbonate is applied to the surface of the field (can be mixed with organic fertilizer), with fertilization, with tillage, water blisters, so that ammonium bicarbonate into the soil. Crops in dry land can be applied, digging ditch facilities.
