Effects On Growth And Yield Of Green Forage Maize By Nitrogen Fertilizer Rate And Fengchanji

Green Forage Maize has the merits of high nutritive value,non-structural carbohydrates,low lignin and large yield per unit area。It's stem,leaf and Fringe all could be used。So that Green Forage Maize became one of some important forage. In this study, Green Forage Maize "Bai ding 1"was selected as research object to study the effects of growth and yield of Green Forage Maize on different nitrogen fertilizer rate and Fengchanji by field experiment of comparison,Character Analysis and the Mathematical Statistic Analysis. The main research results were as follows:1.The different nitrogen fertilizer rate had significant effect on growth and yield of Green Forage Maize "Bai ding 1"。The number of leaves,main stem growth,stem diameter,total stem yield per and total yield per were 13.9,190.5cm,1.98cm,13.28 kg,17.57 kg and 30.85 kg respectively when the Green Forage Maize "Bai ding 1"was treated with 0.1 kg per test plot. When it was treated with 0.15 kg per test plot, these values as mentioned above were 12.2,192.5 cm,2.15cm,15.33 kg,20.92 kg and 36.25 kg respectively. When it was treated with 0.20 kg per test plot, such values were 14.5,203.6 cm,2.3cm,20.09 kg,24.12 kg and 44.21 kg respectively. It is shown that when the Green Forage Maize was treated with 0.2kg urea per test plot, it is conductive to the plant growth with the most number of leaves, the highest of stem, heaviest of leaves and stem. The yield is 43.3% more than that with 0.1kg urea per plot.2. Treatment with Fengchanji had significant effect on growth and yield of Green Forage Maize "Bai ding 1"。The number of leaves,main stem growth,stem diameter total stem yield per and total yield per were 15.47,185.67cm,2.44cm,27.84 kg,17.85 kg and45.42 kg respectively when the Green Forage Maize "Bai ding 1"was treated with Fengchanji. But The number of leaves,main stem growth,stem diameter,total stem yield per and total yield per were 13.6,205cm,2.12cm,14.56 kg,15 kg and29.56 kg respectively when the Green Forage Maize "Bai ding 1"was not treated with Fengchanji. It is shown that when treat with the Fengchanji it can promote plant growth as well, with the most number of leaves, and makes stem stature and thicken, leaves and stems heavy, yield increases. The yield is 53.65% more than that without Fengchanji.All the results suggested that increasing nitrogen rates and Fengchanji conductive to the plant growth and biological yield in Process of Cultivation of Green Forage Maize "Bai ding 1".
