摘要/Abstract

摘要： 本文在小麦生长期内做长效碳铵肥效试验。结果表明:①供肥力长而强,氮素当季利用率高等特点;②小麦经济性状好,产量高;③统计分析^[1],长效碳铵处理较之普通碳铵和尿素处理增产效果均达显著水平且经济效益较好,与普通碳铵和尿素处理比较,纯收入分别增加1065.6元/hm²和683.7元/hm²。

Abstract: The result of the experiment shows that using long-lasting ammonium-bicarbonate on wheat in its growing period not only makes the supply of fertility long and strong and N-availability ratio in this season high, but also makes the economy character good and the yield high, By statistical analysis, compared with usual ammonium-bicarbonate and urea, using the long-lasting ammonium-bicarbonate makes the rising of the yield get significant level. It also could get better economy efficiency compared with usual ammonium-bicarbonate and urea, the added net income is 1065.60 and 683.70 yuan per hm².

Key words: LONG-LASTING AMMONIUM-BICARBONATE, TESTS, USUAL AMMONIUM-BICARNATE, SUPPLY OF FERTILITY, N-AVAILABILITY RATION, NITROGEN NUTRITION
