摘要:
摘要 在施用不同复合肥料的条件下,对保护地蔬菜番茄对N、P、K养分的吸收利用及保护地条件下土壤硝酸盐淋洗进行了研究.结果表明,复合肥的品种及施肥水平对番茄的产量影响不大,与CK相比番茄果实增产12.7%~18.4%;复合肥中N、P养分的当季利用率不足10%,而K素的当季利用率也不超出25%. 传统的大水漫灌条件下,蔬菜保护地土壤硝酸盐的淋洗状况相当严重,并有可能造成地下水的硝酸盐污染. 长期过量施肥及大水漫灌等措施是造成土壤养分累积、硝酸盐淋洗严重、肥料利用率低的根本原因. 图2 表3 参11
Abstract:
Abstract The field experiment was conducted in Shouguang City, Shandong Province. Effects of different complex fertilizer types, nutrient utilization by tomato and nitrate leaching in soil layer were studied in the protected field. The results indicated that tomato yields slightly increased by 12.7%~18.4% with different types of complex fertilizers due to relatively high soil fertility, and no significant differences were found among the treatments with different application rates. The efficiencies of fertilizer utilization were so low that nearly 90% of applied N and P could not be used by tomato. Excessive water and fertilizer input in long term could result in nitrate leaching loss in protected vegetable field. Fig 2, Tab 3, Ref 11
