| 摘 要： | 2004年春在黑龙江省甘南县进行大豆垄间覆膜增温效果试验。通过对地温、气温关系的分析,得出不同膜宽苗带各土层深度地温与气温间的数学关系。地面温度与气温呈对数关系,剖面其他各层地温与气温之间均呈线性关系。覆膜宽度超过40cm,各种膜宽的膜外苗带地温与气温的关系比较稳定,增加膜宽增温作用不明显。

| Abstract: | Based on the heat boost test of overlay film between soybean furrows in Gannan county, Heilongjiang Province in the spring of 2004, and through the analysis on the relationship between the ground temperature and the air temperature, concludes the mathematic relation of ground temperature in different depth and the air temperature by different width of seeding strips. The relation between the surface of ground temperature and the air temperature follows the logarithmic relation, while the relation of the ground temperature in different layers and the air temperature takes on linear type. The width of overlaying film beyond 40 centimeters provides a steady relation between the ground temperature outside the film and the air temperature regardless the width of the film, increasing the effect of boost heat is not obviously. |
