“郝氏造林法”对土壤改良的影响

Effect of "Hao's Afforestation Method" on Soil Improvement

为全面了解"郝氏造林法"对土壤改良的影响,在邢台县太行山地区选取试验地对其土壤化学性质和微生物种类、数量进行调查,并与荒地土壤进行对比分析。结果表明:①与荒地土壤相比,"郝氏造林法"能明显提高土壤碱解氮、速效磷和速效钾含量,各种速效养分增加量不同,其趋势基本一致。②相对于荒地土壤,"郝氏造林法"技术可以显著提高土壤中细菌、真菌和放线菌的种类和数量。

In order to understand the effect of'Hao's Afforestation Method'on the soil improvement.In the Taihang Mountains area of Xingtai County,soil properties,microorganisms species and number were investigated and compared with barren soil.The results showed that:(1)Compared with barren soil,'Hao's Afforestation Method'can significantly improved the content of alkaline N,available P and available K,different amounts of available nutients were added,the trend is pretty much the same.(2)Relative to barren soil,Hao method artificial afforestation can be significantly improved species and quantities of bacteria,fungus and actinomycetes in soil.
