生物菌肥对茄子生长及品质的影响

为研究生物菌肥对茄子生长、产量及品质的影响,于2017年在山西省中部地区进行田间试验,设3个施肥处理(生物菌肥、化肥与不施肥对照),比较分析了茄子株高、开展度等性状。结果表明:3个处理对生育期影响较小,与对照相比较,化肥、菌肥均能提高茄子生长、产量、品质、抗性,其中以生物菌肥处理的产量、品质、抗性表现为最好,667 m~2产量达9 100 kg,茄果纤维素含量为0.009 g/g,可溶性糖含量为0.010%,VC含量为13.380 mg/kg,可溶性蛋白质含量为3.466 mg/g,耐低温弱光指数较高,达4.5,黄萎病抗性强。说明生物菌肥对茄子生长、产量和品质有利,这种施肥方式减少了田间操作次数,降低了经济成本,具有广阔应用前景。

Effects of Biological Fertilizer on Growth and Quality of Eggplant

Abstract: The effects of bacterial fertilizer on the growth, yield and quality of eggplant were studied. The study was conducted in the central part of Shanxi province in 2017. The plant height and development degree of eggplant were compared and analyzed by three fertilization treatments (biological fertilizer treatment, chemical fertilizer treatment and no fertilizer application). The results showed that compared with CK, chemical fertilizer and bacterial fertilizer improved the growth, yield, quality, and resistance of eggplant. The yield, quality and resistance of biological bacterial fertilizer treatment were the best, the yield per 667 m2 was 9 100 kg, and the fruit''s cellulose content was 0.009 g/g, the soluble sugar content was 0.010%, the VC content was 13.380 mg/kg, the soluble protein content was 3.466 mg/g, and the resistance index for low temperature and weak light was 4.5, verticillium wilt was highly resistant. This result showed that biological fertilizer was favorable for the growth, yield and quality of eggplant. This fertilization method reduces the frequency of field operations and the economic cost, and has broad application prospects.
