不同增效剂对设施黄瓜生长及土壤氮磷迁移的影响
Effects of Different Synergists on Cucumber Growth and Soil Nitrogen and Phosphorus Migration
摘要
Abstract
In order to solve the problems of low utilization rate of nitrogen and phosphorus and great loss of migration and leaching caused by excessive application of fertilizer in vegetable fields in facilities,a field experiment was carried out in this study.Using farmers'customary fertilization as control(CK),optimized fer-tilization and optimized fertilization supplemented with polyaspartic acid,fulvic acid,phytase and citric acid(at 150,150,30,30 kg/hm2)respectively were set,and the effects of different synergists on cucumber yield,quality and soil nitrogen and phosphorus migration were studied.The results showed that the four synergists all improved cucumber yield and quality,and the yield of optimal fertilization+polyaspartic acid treatment was 14.52%higher than that of CK.Besides,the synergists effectively reduced the migration and accumulation of nitrogen and phosphorus into deep soil,among which,fulvic acid and polyaspartic acid treatments had the best effects.Under the condition of equal nitrogen input,optimal fertilization+fulvic acid treatment reduced the accumulation of nitrate nitrogen by 13.08%,and optimal fertilization+polyaspartic acid treatment reduced the available phosphorus accumulation by 76.32%in deep(80~100 cm)soil compared with CK.Considering the above results,fulvic acid and polyaspartic acid had better effects on improving the yield and quality of cucum-ber and reducing the loss of soil nitrogen and phosphorus leaching.关键词
