采用盆栽试验方法，研究全生物降解海藻干地膜对土壤保温、保水及对花生幼苗生长状况的影响。结果表明，海藻地膜覆盖可显著提高3.5 cm处土壤温度，中午12∶00可提高2.5℃，对深层土壤保温效果不显著；海藻地膜覆盖可显著提高土壤5 cm处的含水率，相对于空白对照组（CK）可提高16.22%，对深层土壤含水率无显著影响；海藻地膜覆盖可以缩短花生出苗时间，提高发芽率，同时可以显著促进花生幼苗的生长，特别是对花生主茎和第1对侧枝的生长有显著性影响。

Effects of the whole-biodegradable film of seaweed are studied by means of pot culture on soil temperature, soil moisture and peanut seedling growth. Main results are described as follows: compared with CK, the film of seaweed as mulching materials significantly increased the temperature of 3.5 centimeter of soil, soil temperature increased by 2.5 ℃ at 12 ∶ 00, and it has not significant effect on deep soil. The film of seaweed significantly increases the water content of soil in 5 cm, soil water content increased by 16.22% compared with the CK, but it has no significant effect on deep soil water content. Mulching the film of seaweed shorten the time of peanut emergence, improved the germination rate, at the same time significantly promoted the growth of peanut seedling, especially on the growth of the main stem and first pair of lateral branch.
