摘要
以先玉1225号为供试品种,以不施有机肥(常规施化肥)为CK,生物有机肥(M1)、羊粪有机肥(M2)、牛粪有机肥(M3),3种有机肥种类,分别设4个有机肥施用量:T1(3 t/hm^2)、T2(6 t/hm^2)、T3(9 t/hm^2)、T4(12t/hm^2),研究了其对当季土壤养分及玉米产量性状的影响,探索该区不同种类条件下的合理有机肥用量。结果表明:施用生物有机肥对耕层土壤物理性质较CK效果最为显著,特别是生物有机肥施用6 t/hm^2处理,对土壤孔隙度、饱和含水量、田间持水量较CK分别增长24.96%、26.47%、66.01%,土壤容重降低10.74%;3种有机肥均能提高耕层土壤养分含量,但提高效果不十分显著;羊粪有机肥能显著改善玉米的农艺性状,提高玉米商品质量;施用低量牛粪有机肥(3 t/hm^2)时,玉米产量和经济效益最优,分别为14.32 t/hm^2、2.14万元/hm^2,较CK分别提高48.60%、33.75%。3种有机肥均能改善当季土壤肥力,提高玉米产量和增加经济效益,配合化肥施用3 t/hm^2时效果最佳。
Taking maize of "Xianyu 1225" as the tested variety,and appling no organic fertilizer(conventional fertilizer) as CK,three types of organic fertilizers including bio-organic fertilizer(M1),sheep manure organic fertilizer(M2) and cow manure organic fertilizer(M3),and 4 organic fertilizers rates 3,6,9,12 t/hm^2 were applied in this study to explore the reasonable amount of different organic fertilizer types in the area. The results showed that the application of bioorganic fertilizer had the most significant effect on soil physical properties compared with CK,especially the application of bio-organic fertilizer of 6 t/hm^2. The soil porosity,saturated water content and field water holding capacity increased by 24.96%,26.47%,66.01%,respectively,compared with CK soil bulk density decreased by 10.74%. All three organic fertilizers increased soil nutrient content,but the improvement effect was not significant. Sheep manure organic fertilizer could significantly improve the agronomic traits of corn and improve the quality of corn products. When low-level cow manure organic fertilizer(3 t/hm^2) was applied,corn yield and economic benefit were the best,reaching 14.32 t/hm^2 and 21 400 yuan/hm^2,respectively,which was 48.60% and 33.75% higher than CK. All three organic fertilizers can improve soil fertility in dryland,increase corn yield and increase economic benefits,and the best effect when applied with chemical fertilizers at 3 t/hm^2.
