Abstract

Higher or lower concentration of soil Zn, Mn could influence N and P absorption of cotton. The suitable concentration of Zn,Mn could promote absorp tion and accumulation of N, P nutrient in cotton shoot and root, and raise N, P contents of stems, leaves, buds and bolls of cotton, and clearly promote cotton growth and saise yield. Test of water nurture indicaded that Zn, Mn promoting ac tion showed raising root activity, chlorophyll content and cotton plant enzyme a ctivity and thus promoted nutrient absorption, transportation and metabolism of cotton, so utilized rate of N, P was raised, cotton yield was increased.

8 of 9 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
