...)在培养和种植作物幼苗后,比原测定值明显下降,而且施肥培养处理比未施肥培养和施肥种植作物幼苗处理的土壤热水溶性硼(HWSB)都低。其原因:中、酸性土壤的有效钙含量因施肥引入钙离子后而提高,进入土壤胶体的钙交换出的土壤潜在性酸使土壤pH值下降;对于...

The plant availability of soil hot-water soluble boron (HWSB) was tested 5 different arid soils in Hubei province.
用湖北省5种旱地土壤进行了土壤热水溶性硼(HWSB)植物有效性试验。
The result of pot test showed the yield of the crops increased if applying boron in 4 soils with the exception of the alluvial soil in which HWSB was higher than that in other soils.
盆栽试验结果表明,除HWSB较高的潮土外,其余4种土壤施硼均有不同程度的增产效果。盆栽试验和培养实验都证明热水不能完全提取当季施入土壤中的硼,而这些硼在后季作物生长中继续发挥效果。
