中文摘要: |
通过室内盆栽试验,研究不同质地土壤、不同底墒(即初始含水量,下同)、不同底墒增加量下玉米的出苗率,分别就砂土、壤土和黏土三种质地给出了底墒、底墒增加量和出苗率之间的回归方程,并通过方程计算得出三种质地土壤在不同底墒的条件下,达到80%的出苗率所需的底墒增加量。 |
英文摘要: |
he pot experiment was conducted to compare the emergence ratio of corn under different soil textures,different initial moisture contents and different water application,with the purpose of determining the suitable moisture for emergence of corn under different soil textures.The regression equations of emergence ratio to initial moisture content and water application were set up for sand,loam and clay soils respectively.By calculation,the suitable moisture content for the emergence ratio of 80% in these three kinds of soil was proposed. |
