Effect of Nitrogen Fertilizer Operation on the Yield of Wheat
The growth,development and yield of wheat under different nitrogen fertilizer treatments were investigated in Fuyang.The results showed that under different nitrogen application conditions,the plant height,tillering number and rooting number of wheat under N1 treatment were better than other treatments for 1 month,but the overall difference was not significant,indicating that the higher proportion of base fertilizer application had a certain effect on the early growth of wheat.When wheat grew for 7 months,the plant height,total tillering number and rooting number under N4 treatment were significantly higher than those under other treat-ments,and the plant height under N4 treatment was increased by 6.36%,total tillering number was increased by 3.40%and rooting number was increased by 8.46%compared with N1 treatment.The results showed that the plant height,number of tillers and number of secondary roots of wheat were increased effectively by applying proper amount of nitrogen fertilizer.
