    摘要:

    2009～2012年3個(gè)生產(chǎn)周期的試驗(yàn)結(jié)果表明，保護(hù)性耕作高產(chǎn)、高效體系在基本不增加投入的條件下，小麥比傳統(tǒng)耕作平均增產(chǎn)29%，超過(guò)了增產(chǎn)20%的預(yù)期目標(biāo)，保護(hù)性耕作在正常氣候范圍內(nèi)，實(shí)現(xiàn)高產(chǎn)、高效是可能、可行的，為提高保護(hù)性耕作產(chǎn)量和效益，提供了一條有效的途徑。小麥高產(chǎn)、高效的原因，主要是在保護(hù)性耕作基本技術(shù)體系基礎(chǔ)上，加入優(yōu)化種植模式（窄行12 cm、寬行28 cm，小寬窄行）、適當(dāng)加大播種量（10%～20%）和采用溝灌等新技術(shù)內(nèi)容，形成了保護(hù)性耕作高產(chǎn)、高效體系，把保護(hù)性耕作的水土優(yōu)勢(shì)，轉(zhuǎn)化成了產(chǎn)量和效益優(yōu)勢(shì)。

    Abstract:

    The experiment results in 2009-2012 showed that the average yield in conservation tillage high yield and benefit system (CTHYBS) was 29% higher than that in traditional tillage without input increasing, which was more than the expected goal of 20%. It was preliminarily proved that conservation tillage (CT) could realize high yield and benefit under normal weather condition. In order to improve the yield and benefit of wheat, optimum planting mode (12 cm+28 cm narrow/wide row), sowing rate increasing(10%～20%) and furrow irrigation were adopted based on elementary technique system of CT, therefore, an high yield and benefit technique system was formed. The soil and moisture advantages in CT could be transferred to advantages of yield and benefit with CTHYBS. 
