麦田中套种的夏玉米,因与小麦共生一起受到一定的影响,共生期越长、受影响也越大,容易造成根系发育不良、植株细弱、高而不壮。因此,必须抓早管、促早发,使弱苗转壮,才能确保夏玉米高产丰收。一、早间定苗套种玉米早间苗定苗是减少养分消耗、防止苗荒、促根系早发和壮苗的重 Wheat intercropping summer maize, wheat symbiosis with affected by a certain extent, the longer the symbiotic period, the greater the impact, likely to cause poor root development, plant thin, high and not strong. Therefore, we must grasp early management, promote early hair, so weak seed transfer Zhuang, in order to ensure high yield summer corn harvest. First, the morning Dingmiao interplanted corn morning Miao Dingmiao is to reduce nutrient consumption, to prevent shortage of seedlings, and promote root early and strong seedling weight
