针对深施肥或休闲期深施肥沟播技术 ,对冬小麦生育的影响 ,增产效应及产量结构等进行了研究。深施肥或休闲期深施肥沟播生态效应可改善小麦生育条件 ,旱地冬小麦深施肥沟播在干旱或土墒不足的条件下 ,可借墒播种 ,盐碱地采用此技术可躲盐巧种 ,提高出苗率 ,易遭冻害地区的冬小麦 ,可降低分蘖节在土壤中的位置 ,减轻因分蘖节受冻害而造成的死苗 ,死蘖。故在渭北旱原的旱、薄和盐碱地推广此项技术 ,是经济有效的增产、稳产、增收、低耗措施。
Aiming at the deep fertilization and furrow sowing technology during deep fertilization or fallow, the effects on the growth of winter wheat, yield increase and yield structure were studied. Deep fertilization or leisure period of deep fertilization and furrow sowing ecological effects can improve wheat growth conditions, dry land winter wheat fertilization and furrow sowing in drought or soil moisture under conditions, can sowing by moisture, salinization using this technology can hide salt, increase emergence Rate of winter wheat vulnerable to frost damage areas, can reduce the position of tillering knot in the soil, reduce the freezing injury caused by the tillering node dead shoots, dead tillers. Therefore, it is a economical and effective method to increase production, stabilize production, increase income and reduce consumption in dry, thin and saline-alkali areas of Weibei Uygur Autonomous Region.
