摘要
为达到滨海中低产田地区土壤培肥及玉米高产高效的目标,以天津滨海盐碱地区夏玉米为供试材料,采用随机区组试验设计,研究不同有机肥无机肥配施对玉米产量及土壤肥力的影响。结果表明:在滨海盐碱地上种植玉米,施用有机无机肥可以提高玉米籽粒产量,T_(3)处理产量最高为9873 kg·hm^(-2),较不施肥增产53.62%,其他几个处理增产幅度为3.94%~51.88%;盐碱土壤有机无机肥配施可提高土壤速效养分含量,其中T_(3)处理效果最为明显,速效氮、有效磷、速效钾和有机质含量均最高,T_(2)处理效果次之。综上,有机无机肥配施可促进玉米产量和土壤养分的提高,其中以T_(3)处理(33%有机肥+67%化肥)最佳。
In order to improve soil fertility and high yield and high efficiency of corn in the middle and low yield fields in the coastal saline area,summer corn in the coastal saline-alkali area of Tianjin was used as the test material,and different organic and inorganic fertilizers were applied with the design of random block experimental,to study the effects on corn yield and soil fertility.The results showed that the application of organic and inorganic fertilizer could improve the yield of maize.The highest yield of T_(3) treatment was 9873 kg·hm^(-2),which was 53.62%higher than that of CK.The yield of other treatments increased by 3.94%-51.88%.Combined application of organic and inorganic fertilizers in saline alkali soil could improve the content of soil available nutrients.Among them,T_(3) treatment had the most obvious effect,and the contents of available nitrogen,available phosphorus,available potassium and organic matter were the highest,followed by T_(2) treatment.In conclusion,the combination of organic and inorganic fertilizer can promote the increase of corn yield and soil nutrients,which T_(3) treatment(33%organic fertilizer combined with 67%inorganic fertilizer)has the best effect.
