1982年,晋东南地区推广晋庄旱地谷子秋耕壮垡经验,全区160多万亩谷子获得好收成。早春壮垡贵在早,它和一般春耕操作工序基本相同,在顶凌耙耢、土壤解冻之后,施足底肥深耕,随即耢地。不同点是,将春耕时间尽可能地提前一个月,当土地解冻后就立即进行。其好处是,早春气温低水分蒸发量小,土壤解冻含有丰富的返浆水,便于深耕施肥,而且可以使肥料和土壤相融,改良土壤,有益保墒。经过塌墒,使悬虚的土层落实,对小子粒种子发芽生长更具有独特的作用。春播季节天气干旱,经 In 1982, Jin southeast region to promote dry land in Jinzhuang autumn millet Zhuang 垡 experience, the region more than 160 mu of millet get a good harvest. Early spring Zhuangjian expensive in the early, it is generally the same as the general spring plowing process, the top Ling rake 耢 soil thaw, Shi enough deep fat plowing, then 耢 ground. The difference is that the plowing time should be as much as possible a month earlier, when the land is thawed immediately. The advantage is that early spring low temperature evaporation of water is small, the soil thaw is rich in water back to facilitate deep plowing and fertilization, but also make fertilizer and soil blend, improve the soil, beneficial soil moisture. After the collapse of soil moisture, the suspension of the implementation of the soil, the seeds of small seed germination and growth have a more unique role. Spring season is arid weather, after
