Effects of water-retaining reagent of relaxed releasing on the rape growth and soil properties

ZHU Lin~1,YU Zhong-xiang~2,HAN Wen-jie~1,FENG Gui-liang~1,LI Dao-lin~1,Sun Xiu-lun~3,Zhu Kui-feng~3(1.School of Resources and Environmental Science,Anhui Agricultural University,Hefei 230036;2.College of Management Science,Anhui Agricultural University,Hefei 230036;2.Feidong Soil and Fertilizer Station,Feidong 231600)  
In view of the problems of moisture shorting and fertilizer overspending in arid and semi-arid areas and the aims of reducing fertilizer loss and improving nutrient use efficiency,water-retaining reagent of relaxed releasing,water-retaining reagent and routine fertilizer were employed to investigate rape growth and soil properties.The result showed that water-retaining reagent of relaxed releasing provides fitting conditions of moister and nutrition for the plant and improves rape growth,it also has the capability of retaining and holding soil water simultaneously,it improves physical properties of the soil and increases the pore amount in soil.Water-retaining reagent of relaxed releasing possesses continuously accommodation of nutrient.After use of water-retaining reagent of relaxed releasing,available nitrogen would be more than other treatment and NO_3~(-1)-N eluviating would be smaller than other treatment in soil profile.
