中文摘要	采用通气法对盐化潮土-棉花种植体系的CK(种植不施肥)、T1(基肥撒施机械翻耕,追肥沟施灌水)、 T2(基肥撒施机械翻耕,追肥撒施后灌水)、T3(与T1、T2等氮量包膜尿素一次基施)4种处理的田间土壤氨挥发进行原位监测。结果表明,在施N量均为275 kg·hm~(-2)条件下,CK、T1、T2和T3处理基肥NH3-N损失分别为0.621、1.191、1.191和0.826 kg·hm~(-2);追肥NH3-N损失分别为1.088、1.773、2.804和1.374 kg·hm~(-2)。T1、T2和T3来自氮肥的NH3-N损失分别为1.255、2.286和0.491 kg·hm~(-2),分别占施氮总量的0.46%、0.83%、0.18%。在新疆南部绿洲农田,基肥深施后覆膜、追肥结合灌水条件下,棉田土壤氨挥发不是氮肥损失的主要途径;与等氮量传统肥料相比,应用包膜肥料一次施用可明显降低氮肥氨挥发损失。
英文摘要	In Bachu county of main cotton production areas of southern Xinjiang,studied on field in situ determination of ammonia volatilization by using venting method on cotton cropping systems of the salinized fluvo-aquic soil,what four treatments:(i)CK the planting and no fertilizer; (ii)T1 the broadcasting base fertilizer and plowing by machine,and topdressing by furrowing and irrigating; (iii)T2 the broadcasting base fertilizer and plowing by machine,and topdressing by broadcasting and irrigating; (iiii)T3 the one-time basal application of coated urea what equal nitrogen amount with T2 and T3.The results showed that:Under the condition of the amount of nitrogen applied was 275 kg·hm~(-2),the ammonia volatilization of the base fertilizer were 0.621,1.191,1.191 and 0.826 kg·hm~(-2)in the four treatments of CK,T1,T2,T3; and the ammonia volatilization of the topdressing were 1.088,1.773,2.804 and 1.374 kg·hm~(-2).The ammonia volatilization from the Nitrogen were 1.255,2.286 and 0.491 kg·hm~(-2)in fertilization treatments,including T1,T2 and T3,account for 0.46%,0.83% and 0.18% of total fertilization amount,respectively.So,in oasis soils of southern xinjiang,under the condition of the film mulching after base fertilizer deep application and topdressing combined with irrigation,it was not the main way of nitrogen fertilizer losing what the ammonia volatilization in cotton field; Compared with the traditional fertilizer with the equal nitrogen amount,ammonia volatilization of nitrogen fertilizer was decreased significantly by using coated fertilizer in one-time application.
