小麦、玉米、水稻三粮套作是年均温17℃左右,热量资源一年两熟有余、三熟不足地区稻田两熟变三熟的一种新耕作方式。从1988年开始,我们先后在达县罗江镇、蒲家镇及达县市盘石乡进行连续4年试验、示范,收到年年亩产超吨粮的良好效果。几年实践证明,实施这套模式的关键是在发挥两熟耕制常用良种增产优势的基础上,围绕增热争光,有机衔接茬口,综合运用旱地改制、增温育苗、地膜栽培、大规格育秧和喷施生长调节剂等先进技术,重点抓住以下环节。一、引入旱地小麦栽培技术
Wheat, corn, rice, Sanlian suite is an annual average temperature of about 17 ℃, more than twice a year of caloric resources more than three areas of paddy three ripening a new tillage. Since 1988, we have successively conducted experiments and demonstrations in Luojiang Town, Pujia Town and Panshi Township of Daxian County for four consecutive years, demonstrating and receiving the good effect of annual output of over-tonnage of mu per tonne of grain. Several years of practice have proved that the key to implementing this model is to give full play to the advantage of double-crop cultivation of commonly used varieties of seed production, focusing on heating and glory, organic convergence stubble, the integrated use of dry land restructuring, warming seedling, plastic film cultivation, And spraying growth regulators and other advanced technologies, focusing on the following links. First, the introduction of dry land wheat cultivation techniques
