| 摘 要： | 在洮南市北部半山区的果树试验场，按果树树冠垂直投影筑树盘，对树盘进行稻草覆盖处理，研究其对土壤温度与含水量的影响。结果表明：覆草处理能够有效地提高土壤含水量，年平均含水量比清耕地高出16．0％；经覆草处理的土壤，生长前期土温上升缓慢，后期土温下降缓慢，越冬前，土温高于清耕地2．00℃，可减少低温对根系的危害。

| Abstract: | A soil experiment with straw mulch was conducted in an orchard in mid-levels of mountains of northern Taonan City,Jilin Province,China to determine the variation of soil temperature and moisture content.The covering size of straw for a fruit tree is based on the vertical projection of its crown.The result indicates that straw mulch treatment can effectively raise the moisture content.The annual mean moisture content and covered with straw mulch was 16.0% higher than that of control.For the soil treated with... |
