Effect of straw mulch on soil temperature and the moisture content in orchard
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 straw mulch, the soil temperature rises slowly in the early stage of growing season, drops slowly in late stage of growing season, and it is 2.00℃ higher than that of control before overwintering; thus straw mulch treatment can reduce the damage caused by low temperature.
