摘要
为明确生物有机肥肥效及与化肥配施的效果,在宁夏六盘山区冷凉蔬菜生产条件下,研究了生物有机肥与化肥配施对露地娃娃菜生长发育、产量、品质及土壤养分的影响。结果表明,与单施化肥和不施肥处理相比,生物活性有机肥配施化肥条件下娃娃菜产量分别增加885.09 kg·667 m^-2和1367.49 kg·667 m^-2,增幅分别达18.06%和30.94%,且可溶性糖含量显著提升。与单施化肥相比,生物活性有机肥配施化肥条件下土壤有机质、碱解氮、速效磷、速效钾含量分别显著提高6.68%、6.29%、14.41%、4.34%;与不施肥处理相比,生物活性有机肥配施化肥条件下土壤有机质、碱解氮、速效磷、速效钾含量分别显著提高8.11%、7.64%、14.62%、7.46%。综上所述,生物活性有机肥与化肥配施有助于提高娃娃菜产量,提升娃娃菜品质,稳定土壤肥力。
In order to clarify the effect of combined application of bio-organic fertilizer and chemical fertilizer,the growth,yield,quality of baby cabbage and soil nutrients in open field were studied under the production conditions of cold vegetables in Liupanshan district,Ningxia.The results showed that baby cabbage yield of which treated by combined application of bio-organic fertilizer and chemical fertilizer increased by 885.09 kg·667 m^-2(18.06%)and 1367.49 kg·667 m^-2(30.94%)compared with the chemical fertilizer and conventional fertilization(CK)treatments,meanwhile the contents of Vitamin C and soluble sugar were significantly increased.Compared with single chemical fertilizer application and no fertilizer application,the contents of soil organic matter,alkali-hydrolyzed nitrogen,available phosphorus and available potassium were significantly increased by 6.68%,6.29%,14.41%,4.34%and 8.11%,7.64%,14.62%,7.46%,respectively.In conclution,the combination of bioactive organic fertilizer and chemical fertilizer is helpful to increase the baby cabbage yield,improve the baby cabbage quality and stabilize the soil fertility..
