摘要
为了探明生态有机型土壤改良剂对黄壤养分及油菜生长的影响,通过施用自制生态有机型土壤改良剂(T1),对比不施肥处理(CK)、无机肥处理(T2)和有机肥处理(T3),研究不同施肥措施对油菜不同生育期土壤养分含量变化和产量的影响。结果表明,生态有机型土壤改良剂可以显著提高油菜各生育期土壤碱解氮、有效磷和速效钾养分含量,增加油菜产量,土壤改良剂处理的油菜籽粒产量较其它处理提高了7.57%~63.06%。
In order to find out the effects of ecological organic soil amendments on the growth of yellow soil nutrients and rapeseed,the application of self-made ecological organic soil amendment(T1),compared with non-fertilization treatment(CK),inorganic fertilizer treatment(T2)and organic fertilizer Treatment(T3),the effects of different fertilization measures on soil nutrient content and yield in different growth stages of rapeseed were studied.The results showed that the eco-organic soil amendment could significantly increase the content of soil available nitrogen,available phosphorus and available potassium in the growth period of rapeseed,and increased the yield of rapeseed.Yield of rapeseed grain treated by soil amendment are 7.57%~63.06%higher than other treatments.
