Effects of Nitrogen Fertilizer Combination and Fertilization Mode on Growth and Yield of Foxtail Millet[Setaria italica(L.)Beauv.]
摘要
Abstract
In order to find out the optimum combination of different nitrogen fertilizers and fertilization mode in high-yield fertilization of foxtail millet,the foxtail millet variety Yugu 1 7 was used to study the effects of different combinations of nitrogen fertilizers and fertilization modes on the growth and yield of foxtail millet.On the premise of total N amount fixed,seven treatments were set:(1 ) urea was used as base fertilizer only;(2 ) urea was used as base fertilizer and topdressing fertilizer;(3)ammonium bicarbonate was used as base fertilizer only;(4)slow release ammonium sulfate was used as base fertilizer only;(5 )slow release ammonium sulfate and urea were used as base fertilizer only;(6 )slow release ammonium sulfate and ammonium bicarbonate were used as base fertilizer only;(7)ammonium bicarbonate was used as base fertilizer and urea as topdressing fertilizer.The results showed that treatment 6 had the highest leaf area, ear diameter,single panicle weight and yield of foxtail millet,for treatment 6 leaf area was 6.60%, 1.7 7%,9.4 1%,1.0 7%,3.7 2% and 3.4 1% higher,ear diameter was 4.4 1%,2.2 3%,7.2 1%, 2.33%,8.51% and 0.65% higher,single panicle weight was 6.99%,20.25%,26.36%,12.75%, 20.31% and 3.38% higher,and yield was 9.58%,13.93%,21.57%,21.77%,23.08% and 0.99% higher than that of treatment 1,2,3,4,5,7,respectively.关键词
