蓄水覆盖丰产沟土壤生物活性初探

STUDY ON ACTIVITIES OF SOIL ORGANISM OF STORING WATER AND COVERING HIGH—YIELDING—DITCH

本文通过对“蓄水覆盖丰产沟”土壤微生物的数量、分布、生物活性的测定,从土壤生物活性的角度说明“蓄水覆盖丰产沟”在提高作物产量,改土培肥上有较大的作用,同时也为我国北方旱区正确推广“丰产沟”提供理论上的依据。

In the paper the number and distribution of soil microbe and the activities of soil organism soil of the storing water and covering high—yielding—ditch have been determined from one year to four year. The results show that the storing water and covering high—yielding—ditch took great effect on increasing production of crop and improving and fertilizing soil. Meamwhile these gave theoretical base to popularize high—yielding—ditch in region of the North.
