通过9种作物70项次田间试验表明:氯化铵肥效与尿素相当,氯化铵尿素混施略好于单施尿素,得出了水稻、棉花最适施用量,水稻体内氯大致相当于稻谷5—7倍,找出江西地区适宜水稻生长稻草、稻田氯浓度,连续三年施用氯化铵,稻田残留氯大致占施入总量6%;土壤pH降低0.5—0.6;交换性盐基总量下降0.38—2.01cmol kg~(-1),特别是代换性钙下降明显。
Ninety-nine crops through field trials showed that: ammonium chloride fertilizer and urea, ammonium chloride urea slightly better than urea alone, obtained the optimum application of rice, cotton, rice is roughly equivalent to the amount of rice 5-7 times, to find Jiangxi suitable rice growth rice, rice chloride concentration, ammonium chloride for three consecutive years, rice residue accounted for about 6% of total application; soil pH decreased by 0.5-0.6; exchangeable total base Decreased by 0.38-2.01cmol kg ~ (-1), especially the substitutional calcium decreased obviously.
