抗旱造林技术的应用研究

在干旱或荒漠地区造林,降雨稀少,风多且风大,加之人力、物力的贫乏等原因,导致造林成活率低。采用保水剂、保水剂 地膜、保水剂 地膜 生根粉等几种抗旱技术,对臭椿的土壤含水量、生长情况、叶含水量及成活率进行了比较试验。结果表明,干旱地区造林中应用这些抗旱技术,与对照相比,均可以提高土壤含水量、叶含水量以及促进臭椿的生长,其中保水剂 地膜 生根粉综合技术处理的效果最好,保水剂 地膜处理的次之,最后是保水剂处理。干旱或荒漠地区采取有效的抗旱栽植技术,可以有效地解决造林绿化中的难题。

Study on the Application of Techniques of Drought Resistance on the Afforestation

In dry area or sandy dryland, for the reason of scarce rainfall, windiness and lack of labor power and material resources, the low survivor ratio of afforestation were common. Using these techniques, namely, Water retaining agent, Water retaining agent Coverage of plastic film, Water retaining agent Coverage of plastic film Root inducing powder to Heaven Ailanthus, the experiment which aimed to increase water content of soil, water content of leaf, to promote the survivor ratio were carried out. The result showed that: comparing with controls, influences of these methods were significant. Among these methods, the effect of Water retaining agent was good, Water retaining agent Coverage of plastic film was better, and the comprehensive of Water retaining agent Coverage of plastic film Root inducing powder was the best. It is concluded that using techniques of drought resistance in dry area or sandy dryland could solve the problem in afforesting.
