盐碱地上耐盐小麦复播玉米综合效益的研究

Study of the Integrative Benefit Planting Summer Maize after the Harvest of the Salt-enduring Wheat in Salinisation Land

在盐渍化地上直接种植耐盐小麦后复播玉米 ,既是作为快速改良盐碱地的技术措施之一 ,又是充分利用土地、光热、水分等自然资源的重要手段。在北疆条件下 ,本研究的结果为 :土壤盐分 (0～ 5 0cm)含量为 1.0 7%的盐碱地上种植耐盐冬小麦并复播玉米 ,比一般的种植方式增产 6 7%～ 15 2 % ,土壤当年的脱盐率达 84%以上 ,光热资源和水资源的利用较高。这种种植方式有较高的生物产量 ,增加了农田的载畜量。同时既提高了经济效益 ,又有利于培肥土壤、改善土壤结构。

The summer maize have been planted after the harvest of the salt-enduring wheat in salinisation, which is one technical measure of the ameliorating quickly salinisation land and one important means of the utilizing fully natural resources in land, light, water and so on. In the plant means which The summer maize have been planted after the harvest of the salt-enduring wheat in salinisation at soil salinity 1.07%(0～50cm), this test shows the result which increases 67～152% in yield and have be utilized more high in natural resources than the routine plant means ,the salinity content in topsoil descends over 84% , in the condition of the north in Xinjiang. The increased biotic production may be utilized by more domestic animal,raises the economic benefit. Simultaneously, the increased organic muck may fertilize the soil and improve the structure of the salinisation land.
