玉米早晚促高产栽培法,系指玉米适期早播,选用晚熟品种,晚期收获,采用综合的促熟高产措施,而实现高产稳收的综合栽培技术体系。经1986～1990年的研究结果表明,玉米早晚促高产栽培法,较常规玉米栽培法增产31.8％～74.9％。高产的主要理论依据是:充分利用当地热量、光能资源和晚熟品种内涵的增产潜力,大大提高光能利用率,而且具有抗御旱害、冷害、涝害的功能作用,为实现玉米高产稳收开创了新途径。
The method of promoting high-yielding cultivation of corn sooner or later, refers to the early sowing of corn suitable period, the choice of late-maturing varieties, late harvest, using comprehensive measures to promote high yield and improve yield and stability of the integrated cultivation technology system. The results of the research from 1986 to 1990 showed that the high-yielding cultivation of maize increased 31.8% -74.9% more than the conventional corn cultivation. The main theoretical basis of high yield is: make full use of local heat, light energy resources and late maturing variety of yield potential, greatly improve the utilization of light energy, but also has the function of fighting drought, chilling damage, waterlogging harm, in order to achieve high yield and stability of corn Create a new way.
