Abstract

After analysing dynamic changes of chemical properties of soil covered with rice straw , rice straw plus rice chaff and bamboo leaves (treatment No .1 , No .2 , and No .3 respectively ) in Phyllostachy praecox forests , three points were concluded .①By the day 50 , contents of soil organic matter and total nitrogen had begun to reduce obviously .The first two treatments remained this tend until the end of experimtnt (the total-reduced-values of two contents were 7.28 gkg-1 9.55 gkg-1 and 0.50 gkg-1 , 0.57 gkg-1 respectively).The two contents of the third treatment , however , increased again by the end of the experiment .②The peak value of hydrolyzable nitrogen in three treatments appeared on the day 50 , afterwards , the value began to decrease with day rapidly in the first two treatment (only 57.68 % and 55.71 % compared with the peak value at the end of the experiment).The hydrolysable value of third treatment decreased slowly .③Contents of exchangeable base and pH value in three treatments appeared the same dynamic tends .After the peak value on the day 75 , they went down again .
