摘  要：
2010年以来连续3年在鄂北地区开展了稻茬小麦免耕栽培试验,对免耕机械条播和常规栽培稻茬小麦的次生根和分蘖发生、穗粒数及实际产量进行了比较,并对免耕机械条播稻茬小麦的生产效益进行了分析,研究稻茬小麦免耕栽培技术的应用效果,分析稻茬小麦免耕栽培技术增产增效的原因。结果表明,在小麦6.6叶龄时,免耕机械条播稻茬小麦次生根条数为10.8条,分蘖2.2个,比对照分别增加2.2条和0.5个。免耕机械条播稻茬小麦子粒产量比对照增加8.9%~14.0%,平均增加11.5%。2011-2013年,免耕条播稻茬小麦较对照平均节省人工10.5个/hm2,合计节省投入2 187.0元/hm2,免耕条播稻茬小麦产量增收1 050.9元/hm2,合计比对照增加效益3 237.9元/hm2。

摘  要：
To study the effects of no-tillage drilling technique on wheat production in rice-wheat rotation system in Northern Hubei province and understand the yield and profit increase caused by this management, no-tillage drilling experiments were conducted in 3 crop seasons since 2010. The secondary roots, tillers, kernels per spike and the actual yield of wheat under no-tillage drilling management and conventional cultivation were compared and the benefits of no-tillage drilling management were analyzed. The results showed that one plant of no-tillage drilled wheat had 10.8 secondary roots and 2.2 tillers at the leaf age of 6.6. The grain yield of no-tillage drilled wheat increased with 8.9% to 14.0% compared with the control, with an average increase of 11.5%. The total input saved by no-tillage drilling management was 2 187.5 yuan per hectare. The notillage drilling management increased 1 050.9 yuan of income through yield increase per hectare. The profit was increased3 238.4 yuan by no-tillage drilling management per hectare compared with the control.
