鲁玉二号自1981年引进,1982年百亩高产试验亩产玉米522.7公斤,1983年即进行鲁玉二号的高产栽培模式试验与研究,取得了显著效果。海头镇南朱皋村干亩高产模式栽培试验方,1983～1986年亩产玉米依次为571.8、556.1、552.2和568.7公斤,连续4年单产超过550公斤,1986年模式栽培示范点,朱堵乡店子村2.1亩鲁玉二号单产622.5公斤,龙河乡吴村20亩单产607.9公斤,城南乡竹园村700亩,单产589.6公斤。经过连续4年的试验与研究,初步模索出夏玉米鲁玉二号亩产550公斤生长规律与关键技术,现将其数量化指标整理如下:
Luyu II was introduced in 1981, yielding 522.7 kilograms of corn per mu in 1982 with high-yield test. In 1983, Luyu No.2 high-yielding cultivation experiment was conducted and achieved remarkable results. From 1983 to 1986, corn yield per mu was 571.8,556.1,552.2 and 568.7 kilograms respectively, yielding more than 550 kilograms per mu for 4 consecutive years. In 1986, model planting demonstration sites and Zhu blockages Township sub-village 2.1 acres Luyu yield 622.5 kg two, 20 acres of Long Wu village 20 acres yield 607.9 kilograms, Chengnan Township Chuk Yuen Estate 700 acres, yield 589.6 kilograms. After 4 consecutive years of trial and research, the preliminary output of summer corn Lu Yu 550 kg per mu yield growth and key technologies, the quantitative indicators are now sorted as follows:
