| Abstract: | The nutrient absorption of spring maize is improved by film.The relative quantities of absorption of N,P 2O 5,K 2O is increased by 0.39 0.74,0.10 0.26,0.29 0.46 per cent,respectively.The accumulated amount per hectare is increasd by 138.0,29.5,123.2kg,respectively.The consumption coefficient of N,P 2O 5,K 2O is increased by 0.41,0.20,0.46 per cent,respectively.The productivity is decreased by 10.8,11.7,4 per cent,respectively.The N.P.K.fertilizer utilization is increased by 15,58 per cent,respectively. |
