粉煤灰磁化复合肥对一些经济作物的增产效应研究

Study on effect of application of magnetized fly ash compound fertilizer on yield of industrial crops

在砂姜黑土、潮土、黄褐土等不同土壤类型 ,花生、大豆、芝麻、油菜、棉花等经济作物施用粉煤灰磁化复合肥均有显著增产效应 ,花生增产 2 0 .2 %～ 2 9.7% ,大豆增产 2 5.9%～ 34.9% ,芝麻增产 1 4.3%～ 55.3% ,油菜增产 2 1 .9% ,棉花增产 2 5.6%。

The magnetized fly ash compound fertilizer is a new type of fertilizer. Experimental study on effect of this fertilizer on industrial crops and their yield was conducted. By applying magnetized fly ash compound fertilizer soybean yield was 1 722 kg/hm 2 ～2 910 kg/hm 2, Which was 25.9%～34.9% higher than the CK's; Peanut yield was 3 699 kg/hm 2～5 562 kg/hm 2, 20.2%～29.7% higher than the CK's; Sesame yield was 1 315.7 kg/hm 2～1 657.5 kg/hm 2, 14.3%～55.3% higher than the CK's; Hybrid oil cabbage yield was 2 007 kg/hm 2, 21.9% higher than the CK's; Cotton yield was 1 074 kg/hm 2, 25.6% higher than the CK's.
