玉米双株紧靠栽培就是在保证每亩正常株数的情况下,每穴长两株玉米,而且这两株玉米要紧靠一起。这种栽培方法的优点是,由于玉米穴间距离扩大了近两倍,在一定程度上改善了通风透光条件,提高了光合作用强度,有利于玉米增产。实现双株紧靠栽培必须采用精(少)量点播,可省种1/2—2/3。此外,这种栽培方法较常规栽培法的穴数减少1/2,又很少间苗,可大大减少播种、间苗、中耕、追肥用工(一般每亩省工1—1.5个)。近几年的多点试验均取得很好的增产增收效果。1983年赵屯乡刘忠良
Double crop close to the cultivation of corn is to ensure the normal number of strains per acre case, two corn per long, and the two corn to be together. The advantage of this cultivation method is that since the distance between corn holes has nearly doubled, ventilation and light conditions are improved to a certain extent, the photosynthesis intensity is increased, and the corn yield is increased. To achieve close double-crop cultivation must be fine (less) on-demand, can save 1 / 2-2 / 3. In addition, this method of cultivation compared with conventional cultivation method to reduce the number of holes 1/2, and rarely thinning, can greatly reduce the sowing, thinning, cultivating, top dressing workers (usually 1-1.5 per acre provincial workers). In recent years, many tests have achieved good yield and income effects. In 1983 Zhaozhong Township Liu Zhongliang
