土地整理导致土壤肥力及生产力降低,施用有机肥是培肥土壤的有效措施,然而不同类型有机肥对土壤培肥效果存在差异。本文通过田间试验研究了不同有机肥处理烤烟生长发育、生物量、养分吸收及烤烟收获后土壤养分状况,结果表明:对比不施肥(T1),菜枯饼肥+ 化肥(T3)、紫云英+ 化肥(T5)在第20 d的烤烟株高分别显著(P < 0.05)高19.73%和21.77%,在30 d的叶片数均显著(P < 0.05)多14.55%;油菜秸秆+ 化肥(T4)在第30和60 d的叶片数显著(P < 0.05)多18.18%和24.16%,株高分别显著(P < 0.05)高19.73%和55.12%。油菜秸秆和紫云英对烟叶和生物产量有显著(P < 0.05)增产作用,油菜秸秆对烤烟秸秆具有减产的作用。三...

Land consolidation reduces soil fertility and productivity.Application of organic fertilizersis an effective was to increase soil fertility.However, there is discrepancy in effect of different organic fertilizerson soil fertility. In this paper, a field experiment was designed to determine effects of different organic fertilizers on tobacco's growth, biological yield and nutrient absorbing amount as well as soil nutrient features after tobacco collected, which could provide references for soil fertility improvement of tobacco field after land consolidation. The results showed that the plant he...
