- 摘要:
- 以生菜为试材,研究不同氮肥对日光温室生菜产量、品质及土壤环境的影响。结果表明:施肥显著提高生菜产量,以有机肥化肥配施增产效果最好。施肥降低生菜可溶性糖含量、提高可溶性蛋白质含量,均以单独施用化肥变幅最大;施肥显著提高生菜维生素C含量,以单独施用有机肥最高,有机肥化肥配施次之;施肥显著提高生菜硝酸盐和亚硝酸盐含量,单独施用化肥增幅最大,有机肥化肥配施次之,单独施用有机肥最小。单独施用化肥显著提高了土壤电导率、pH值及可溶性盐含量、碱解氮含量,有机质、速效P和速效K含量略有降低;单独施用有机肥、有机肥化肥配施则显著降低了土壤pH值,显著提高了土壤有机质和碱解氮含量,土壤可溶性盐、速效P、速效K含量及电导率值略有提高。在日光温室生产中,有机肥化肥配施利于协调产量、品质、土壤环境关系,实现可持续发展。
- Abstract:
- Taking lettuce as test material,the effect of different nitrogen fertilizers on lettuce yield,quality and soil environment were studied.The results showed that fertilization significantly increased the yield of lettuce,production increase effect of organic fertilizer+chemical fertilizer was the best.Fertilization decreased the soluble sugar content,soluble protein content of lettuce was increased,all with separate fertilizer was the highest;fertilization significantly increased the vitamin C content of lettuce,as a single application of organic fertilizer was the highest,organic fertilizer+chemical fertilizer secondly;fertilization significantly increased nitrate and nitrite content,the largest increase in separate fertilizer,organic fertilizer+chemical fertilizer secondly,single application of organic manure minimum.Application of chemical fertilizer significantly increased soil electrical conductivity,pH value and soluble salt content,nitrogen content,organic matter,available P and available K content decreased slightly;the separate application of organic fertilizer,organic fertilizer+chemical fertilizer significantly decreased soil pH value,significantly increased soil organic matter and nitrogen content,soil soluble salt,available P,available K content and electric conductivity value increased slightly.In sunlight greenhouse production,combined application of organic fertilizer+chemical fertilizer was in favour of coordinating the relationship between yields,quality,soil environment,to realize the sustainable development.
