沧州运东广大麦区土壤耕层存在不同程度盐碱,为探索盐碱地冬小麦增产增效技术,近年来,我们在当地不同类型,不同程度的盐碱地上进行了反复试验、示范,取得了一些成功的经验,现归纳总结如下,供参考。一、滨海盐碱地小麦生育特点1、生育期略长。滨海盐碱地小麦进入越冬期早5～8天,返青晚10天左右,拔节晚4～11天。前期生长慢,后期生长快,籽粒灌浆期短,全生育期有所延长。2、根量少,发育晚,叶片短而窄。滨海盐碱地小麦根系生长弱,初生根小,次生根发育晚,数量少,干重低。叶片比一般麦田短而窄,叶色深绿,
In order to explore the technology of yield increasing and efficiency of winter wheat in saline-alkali land, we have carried out repeated experiments and demonstrations on different types and degrees of saline-alkali soil in the local area, and achieved some successes Experience, are summarized as follows, for reference. First, coastal saline soil wheat growth characteristics 1, slightly longer growth period. Coastal saline-alkali wheat enters the overwintering period as early as 5 to 8 days, turning green late about 10 days, jointing night 4 to 11 days. Early growth slow, rapid growth late, grain filling period is short, the whole growth period has been extended. 2, less root, late development, short and narrow leaves. Coastal saline-alkali wheat has weak root growth, low primary root growth, secondary root development, low number and low dry weight. Leaves shorter and narrower than the general wheat field, dark green leaves,
