1.深耕整地玉米具有庞大的根系,要求深耕整地,疏通空气,结合增施有机肥,减轻雨水径流,增加土壤水分渗透量,加强土壤保水性,有利于玉米生长,提高抗旱能力,防止倒伏。从大面积生产看,耕层由19-21厘米逐渐加深到23-24厘米,可以显著增产。整地要精细,最好要秋翻秋整地,秋耕后立即耙压,达到播种状态。秋翻春整地的在早春化冻5-7厘米时及时起垄,顶浆起垄。一般要求达到地面平整、土块细碎.没有
Deep plowing land preparation Maize has a huge root system, requires deep plowing the land, clear the air, combined with organic fertilizer to reduce runoff, increase soil water infiltration, and enhance soil water retention, is conducive to the growth of corn, improve drought resistance and prevent lodging. In large-scale production, the topsoil gradually deepens from 19-21 cm to 23-24 cm, which can significantly increase production. Site preparation should be fine, it is best to Qiuqiuqiu alder, rake immediately after autumn plowing, to sowing state. Spring autumn spring soil preparation in the early spring when the 5-7 centimeters ridge prompt ridging, apical ridge ridging. General requirements to achieve a smooth ground, soil parcels
