摘要
从理论上分析了地面覆盖材料对土壤温度进行调节作用的机制及地面覆盖材料光谱透射率对土壤温度影响的机理,通过试验确定了农业生产上常用的地面覆盖材料透明聚乙烯薄膜,黑色聚乙烯薄膜和黑色地面覆盖纸在300至800nm波长范围内的光谱透射率。在田间试验的基础上。
On the basis of theoretical analysis, a mechanism of soil temperature changing under soil cover and the influence of spectral transmission of mulch materials on soil temperature were given. Through experiment, the spectral transmissions of mulch materials used in plant cultivation, such as transparent LD PE film, black LD PE film and black paper, were determined in the wave length from 300 to 800 nm respectively. The quantitative effects of soil cover with these mulch materials on the soil temperature were studied by means of field test.
