摘要
Abstract
[Objective]In order to clear the optimum nitrogen amount in cotton field in Eastern Hebei. [Method]In 2009 and 2010 in Tang hai County, the effects of different nitrogen amounts on the growth and development and yield of cotton were studied in saline fields. [Result]The results indicated that no nitrogen had big effects on the growth and development of Binmian No. 2, and comparing with different nitrogen application treatments, its plant height, fruit branch number, boll setting number all decreased, and seed cotton yield inclined significantly. With the increasing of nitrogen amount, plant height, fruit branch number and boll setting number of cotton had a rising trend. Different nitro gen amounts had important influences on the growth and development and yield of cotton, but the excess nitrogen was not benefit on yield in creasing. [Conclusion]The optimum nitrogen amount was 337. 5 kg/hm2 in saline fields of Eastern Hebei.关键词
