摘    要:为了研究土壤调理剂“艾作迈”(Azomite)对节水抗旱稻(WDR)生长发育和产量的影响,在节水栽培模式下,以杂交节水抗旱稻品种‘旱优8号’为试验材料,按照施氮量设160 kg/hm2(LN)、200 kg/hm2(NN)和240 kg/hm2(HN)3种肥力水平,以不施“艾佐迈”土壤调理剂为对照进行田间试验。结果表明:在3种氮肥水平下,施用“艾佐迈”都使‘旱优8号’植株剑叶叶绿素含量、株高、单株有效穗、穗长、单株产量增加,在LN和NN水平下实际产量显著增加6.41%和11.1%。在土壤营养方面,施用“艾佐迈”对土壤pH没有影响;3种氮肥水平下土壤全氮含量、速效钾含量比对照降低,在LN和NN水平下,施用“艾佐迈”使土壤有机质含量和速效磷含量增加,在NN和HN水平下,施用“艾佐迈”的处理土壤速效氮含量比对照增加。

The Application of Azomite on Water-saving Drought-resistant Rice
Abstract:In order to study the effect of Azomite on growth and yield of ‘Hanyou8’, a water-saving and drought-resistant rice, was used as the sample, the experiment was carried under three N rates including 160 kg/hm2 (LN), 200 kg/hm2 (NN) and 240 kg/hm2 (HN). No Azomite fertilizer as a control, the experiment was carried under water-saving cultivation mode. The results show that: in the three N rates, Azomite could increase plants flag leaf chlorophyll content, plant height, panicle number, spike length, grain yield of ‘Hanyou8’, in LN and NN, the actual yield was increased 6.41% and 11.1% respectively in significantly. In the soil, Azomite has no effect on soil pH. The total N and available P reduced in three N rates. Soil organic matter, available P was increased in LN and NN treatments; available N was increased in NN and HN treatments.
Keywords:N fertilizer
