烟草秸秆生物有机肥对大豆的影响试验研究

目的]通过烟草秸秆生物有机肥在大豆栽培中的应用研究,考察烟草秸秆生物有机肥对大豆品种的丰产性、稳定性、抗逆性、品质及其他重要特征的影响。方法]以恩豆31为试验材料,采用随机区组法,结果采用RCT99软件进行分析。结果]施用化肥和烟草秸秆肥作底肥都有显著的增产效果,其中施用600和900 kg/hm2烟草秸秆肥比施用300和450 kg/hm2N︰P︰K 15%︰15%︰15%三元复合肥作底肥增产;施用烟草秸秆生物有机肥处理在生物学性状上表现为植株较矮、结荚数较多。结论]在大豆生产中用烟草秸秆有机肥作底肥时适当加入氮肥则增产效果更加显著,经济效益更高。

Experimental Research of the Effects of Tobacco Straw Biological Organic Fertilizer on Soybean

Objective ] The aim was to investigate the effects of tobacco straw biological organic fertilizer on soybean yield, stability, stress resistance, quality and other important features through the application research of the tobacco straw biological organic fertilizer in soybean cultivation. Method] Endou 31 was taken as experimental material and the randomized block method was used. The results were analyzed with RCT99 software. Result] Application of fertilizer and tobacco straw fertilizer as base fertilizer both had a significant effect of increasing yield, thereinto, the yield of using 600 and 900 kg/hm^2- tobacco straw biological organic fertilizer as base fertilizer had increased than that of 300 and 450 kg/hm^2- N, P, K three element compound fertilizers （ N： P2 PO5 ： K2O 15 % ： 15 % ： 15 % ） ; the treatment of application of tobacco straw biological organic fertilizer showed lower plant height and more pod number in the performance of biological traits. Conclusion] During soybean production, when using tobacco straw biological organic fertilizer as base fertilizer, adding to N fertilizer properly shows more significantly yield increasing effects and higher economic benefit.
