有机肥和化肥配施对菜豆生长和产量的影响

Effects of Combined Application of Organic Manure and Chemical Fertilizers on Growth and Yield of Common Bean

为了探究有机肥和化肥配合施用对菜豆的影响,通过田间小区试验,研究了有机肥和复合肥、磷肥不同施肥量组合对菜豆生长和产量的影响。结果表明,施用7500 kg/hm^2有机肥的3个处理(T1、T2、T3)和施用15000 kg/hm^2有机肥的3个处理(T4、T5、T6)之间对菜豆各生育时期的形态指标、生理指标以及产量影响较小,当配合施用复合肥和磷肥时会使产量提高;有机肥、复合肥、磷肥分别为15000、900、300 kg/hm^2(T6)处理的产量最高,达35971 kg/hm^2,而有机肥、复合肥、磷肥分别为7500、675、150 kg/hm^2(T3处理)的产量为34946 kg/hm^2,仅次于T6处理,且T3处理的大多数指标与T6处理间无显著性差异。综合考虑得出,最优肥料施用量组合为有机肥7500 kg/hm^2、复合肥675 kg/hm^2、磷肥150 kg/hm^2。

To explore the effect of combined application of organic fertilizer and chemical fertilizer on common bean,this experiment studied the effects of different fertilizer application rates of organic fertilizer,compound fertilizer and phosphate fertilizer on the growth and yield of common bean through field plot experiment.The results showed that the effect of three treatments with 7500 kg/hm^2 organic fertilizer(T1,T2,T3)and the three treatments with 15000 kg/hm^2 organic fertilizer(T4,T5,T6)on the morphological indicators,physiological indicators and yield of common bean growth period were less.When compound fertilizer and phosphate fertilizer were combined,the yield increased.The yield of T6 treatment(organic fertilizer 15000 kg/hm^2,compound fertilizer 900 kg/hm^2,phosphate fertilizer 300 kg/hm^2)was the highest,which was 35971 kg/hm^2,while the yield of T3 treatment(organic fertilizer 7500 kg/hm^2,compound fertilizer 675 kg/hm^2,phosphate fertilizer 150 kg/hm^2)was 34946 kg/hm^2,and most indicators were not significantly different with T6 treatment.Comprehensive consideration,the optimal fertilizer ratio treatment was organic fertilizer 7500 kg/hm^2,compound fertilizer 675 kg/hm^2,phosphate fertilizer 150 kg/hm^2.
