摘要
蔬菜是重要的经济作物,许多种植户为追求片面的高产量、高收益,连续多年种植蔬菜、偏施重施化肥,导致土壤严重酸化,产量受到严重影响.为探讨土壤调理剂对蔬菜产量和酸化土壤改良的影响,本研究开展了木耳菜产量和土壤性质在常规施肥、常规施肥+天脊土壤调理剂、常规施肥+钙镁磷肥等不同处理的对比试验,试验结果表明,天脊土壤调理剂和钙镁磷肥对木耳菜的增产效果分别是62.6%,29.7%;两种调理剂处理后,叶片中氮磷钾元素都有增加,增幅在13.5%~65.5%;两种调理剂处理后土壤交换酸总量降低幅度达41.9%和16.8%,对土壤交换性阳离子含量和元素含量均具有一定的调节作用.本研究对土壤调理剂对木耳菜产量和土壤理化性质的影响进行了检测,以期为蔬菜生产提供参考.
Vegetables are important economic crops. Many growers continuously grow vegetables for many years and apply excessive chemical fertilizer to pursue high yield and high income. This planting method led to serious acidification of soil and reduction of vegetable yield. In order to explore the effects of soil conditioner on improvement of vegetable yield and acidified soil, the field experiments were conducted. The results showed that the yield increasing effect of Tianji soil conditioner and calcium magnesium phosphate fertilizer on malabar spinach were 62.6% and 29.7%, respectively. After treatment with two soil conditioners, nitrogen, phosphorus and potassium in leaves increased by 13.5%~65.5%, and total amount of exchangeable acids in soil decreased by 41.9% and 16.8%, which showed a certain regulation effect on exchangeable cation content and elements contents in soil. This study analyzed the effects of applying soil conditioner on the yield of malabar spinach and soil physical and chemical properties, so as to provide reference for vegetable production.
