| 摘 要： | 利用盆栽试验和田间试验研究了榨菜叶还田对土壤养分肥力的影响,结果表明,榨菜叶还田处理土壤碱解氮、速效磷、速效钾含量在水稻整个生长期变化较小,水稻生长后期土壤速效N、P、K含量都高于化肥处理;而化肥处理氮磷钾含量变化较大,说明榨菜叶养分供应能够与作物的吸收相互协调,养分供应持续稳定,能满足水稻生长后期对NPK养分的需要,是一种天然的缓释肥料。在水稻生长期,榨菜叶还田能明显的提高土壤肥力,与对照相比,水稻收获后不同处理土壤有机质含量、土壤氮、磷、钾含量,均有所上升,以榨菜叶及其配施化肥处理上升的幅度较大,培肥效果较好。 |

| Abstract: | Effect of preserved szechuan pickle leaves return to soil on soil fertility was studied by pot trial and field experiment.The results showed that soil available N,P and K contents in the preserved szechuan pickle leaves treatments were constant during the whole growing season of rice,but the contents of soil available N,P and K were all higher in the leaves return treatment than those in the chemical fertilizer treatments at the late stage of rice growth.This indicated that preserved szechuan pickle leaves could provide nutrients continuously and stably to the need of the rice for N,P and K at the late stage.Therefore,preserved szechuan pickle leaves could be regarded as a kind of naturally slow release fertilizer. |
