| 摘 要： | 以枳砧兴津温州蜜柑和椪柑成年树为试材,进行施用氯化铵与等氮量尿素的对比试验。连续3年的试验结果表明,每年株施氯化铵1.5公斤(含氯量约1000克),与等氮量尿素的肥效相当,且对树体生长、结果、果实品质及贮藏性等均无实质性不良影响。另设重施氯化铵的附加处理,发现每年株施氯化铵3公斤(含氯量约2000克)以上,施用后几个月即出现盐害反应,对柑桔产量、果实品质及树体生长产生严重影响。

| Abstract: | The satsuma mandarin (Citrus unshu Marc.) and ponkan (C. reticulata Blanco) trees on trifoliate orange rootstocks were used as test materials to conduct a comparison experiment of the effects of ammonium chloride(NH_4Cl) and urea at equal nitrogen contents. The results three years in succession showed that when ammonium chloride was applied at 1. 5 kg per tree each year (contained chlorine about 1 kg), it had the equal fertilizer effect to the urea at equal nitrigen contents, and it were not pernicious to the tree growth, fruiting, fruit quality and fruit storability. The results from another additional experiment showed that, when ammonium chloride was applied, over 3 kg per tree each year (cotained chlorine about 2 kg), it would result in salt stress and affected yield and quality of fruit as well as tree growth seriously. |
