摘  要:
在河西走廊荒漠化土壤上种植中麻黄,改土培肥效果十分明显。3年生麻黄草鲜草重12.17t/hm2,折干重4.87t/hm2,与CK比较0~20cm土层中自然含水量增加64.29g/kg,>0.25mm团粒结构增加14.31%,总孔隙度增加11.32%,体积质量(容重)降低0.30g/cm3,pH由8.32降到7.99,全盐含量降低1.72g/kg,脱盐率达到49.85%,有机质、速效N、P、K亦随之增加。

摘  要:
The effect of cultivation of Chinese ephedra (Ephedra intermedia) on the desert soil in the Hexi Corridor Region is significant in soil building. After planting the crop for 3 years, the yield of the 3 year-old crop reached 12.17 t/hm2 in fresh weight and 4.87 t/hm2 in dry weight. Compared with CK, the soil at 0 ~ 20 cm increased its natural moisture content by 64.29 g/kg, water-stable granular structure (> 0.25mm) by 14.31 %, total porosity by 11.32 %, and decreased its soil bulk density by 0.30 g/cm3, pH from 8.32 to 7.99, and total salt by 1.72 g/kg or by 49.85 %. Along with the change in its physical properties, its contents of soil organic matter, readily available N, readily available P, and readily available K increased, too.
