Demonstration Application Effect of Slow Release Bulk Blending Fertilizer and Loss-Control Fertilizer on Maize
In order to clarify the yield increasing effects of slow release bulk blending fertilizer and loss control fertilizer,the demonstration experiments of slow release bulk blending fertilizers(N-P2O5-K2O=26-11-12,23-14-13 respectively)and loss-control fertilizer(N-P2O5-K2O=26-10-12)produced by Anhui Hongsifang Co.,Ltd.in 13 maize fields are summarized.The results show that comparing with conventional fertilization treatment,the maize ear length increased by 0.2-2.4 cm and 0.1-2.5 cm,and the number of grains per row increased by 1-4 and 0-3,respectively,when treated with two slow release bulk blending fertilizers.The average yield increase rates are 3.9％and 3.8％,respectively.Compared with conventional fertilization treatment,the maize ear length increase by 0.1-1.8 cm and the number of grains per row increase by 1-8,with an average yield increase of 5.6％,when treated with loss-control fertilizer.
