试验证明,氯化铵对春小麦的增产效果与等氮量的尿素和硝酸铵相同或相近。同一地块连续施用3年氯化铵对春小麦的生长发育、产量和品质均无不良影响。春小麦在土壤含氯量<600μg/g可正常生长;1000μg/g明显受害; 2000μg/g严重受害;>3500μg/g全部致死。春小麦在种子萌发至出苗期对高氯毒害最为敏感,此后逐渐减轻。植株含氯量随施氯量的增加而增加,所吸收的氯90%以上分布在茎叶中,籽粒积累甚少。残留在土壤中的氯到第3年收获后已大部分淋洗到60cm以下,但100cm以上仍残留37.8%～43.2%,150cm以上残留40.1%～69.3%。在春小麦能够正常生长的范围内,施氯对土壤硝化作用无明显抑制作用。
Tests show that ammonium chloride on spring wheat yield and isobaric N urea and ammonium nitrate the same or similar. Continuous application of ammonium chloride in the same plot for 3 years had no adverse effect on the growth and development, yield and quality of spring wheat. Spring wheat in the soil chlorine content <600μg / g can grow normally; 1000μg / g obvious damage; 2000μg / g serious damage;> 3500μg / g all lethal. Spring wheat is the most sensitive to high chlorine poisoning in seed germination to emergence, and then gradually reduced. Chlorine content of plants increased with the increase of chlorine application, the absorption of more than 90% of the chlorine in stems and leaves, the accumulation of little grain. Residues of chlorine in the soil after the third year of harvest have been most of the leaching to 60cm or less, but still more than 100cm 37.8% ~ 43.2%, 150cm above the residue 40.1% to 69.3%. In the range of normal growth of spring wheat, the application of chlorine has no obvious inhibitory effect on soil nitrification.
