化学调控栽培是农业生产的一项增产增收新技术,现已在棉花上广泛应用。该项技术近几年才在玉米上推广使用,取得了显著的经济效益。 据全国20个省、市的大面积示范、推广。此项技术可使玉米植株矮化15~20厘米,穗位降低15~18厘米,且茎秆坚韧,根系发达,抗倒伏能力增强。同时,还可以使每亩增加1000~1500株,叶面积系数从4.0提高到5.5~6.0,有利于发挥高秆大穗型玉米的增产潜力。增产幅度一般为10%~30%。是一项方便、经济的增产新技术。
Chemically regulated cultivation is a new technique of increasing production and increasing income in agricultural production and is now widely used on cotton. In recent years, this technology has been popularized on corn and has achieved significant economic benefits. According to the national 20 provinces, municipalities large-scale demonstration and promotion. This technology can make dwarf corn plant 15 to 20 cm, ear reduction 15 to 18 cm, and stem tough, developed root system, lodging resistance increased. In the meantime, it is also possible to increase 1000-1,500 plants per acre and raise the leaf area coefficient from 4.0 to 5.5-6.0, which is beneficial to exert the stimulation potential of high-stalk large-spike corn. Yield increase is generally 10% to 30%. Is a convenient, economic stimulation of new technologies.
