丘陵旱地油后棉机械直播示范成效及栽培要点

The Demonstration Effects and Key Points of Cultivation of Mechanical Direct Seeding Cotton after the Rape Cultivation in Hilly Dryland

为探讨棉花轻简化栽培技术途径^([1]),2014年在都昌县大沙镇开展了"50亩"集中连片油后棉机械直播示范,平均子棉单产达4050kg/hm^2,在单产不减的情况下显著地降低了生产成本,起到了良好的节本增效示范效果。同时总结出了该模式的高产栽培技术要点。

To investigate the approach of cotton light simplified cultivation techniques , it carried out mechanical direct seeding cotton after the rape cultivation in ＂contiguous 50 mu＂ of Duehang Dasha town in 2014. The average seed cotton yield reached 4050 kg/hm2 , it significantly reduced the production costs under not decreasing yield. It played a good effect of dem- onstration on the saving cost and improving efficiency. Meanwhile, it summarized the key points of high yield cultivation tech- niques of the model.
