Impacts of different soil fertility improvement practices with film mulched ridge-furrow til-lage on soil nutrient content, maize yield, and water use efficiency in Northwest China.

Improvement of soil quality is one of the most important ways to enhance fertility for efficient dryland crop production. However, the effects of different fertilization measurements with film mulched ridge-furrow tillage on soil fertility, crop yield, and water use efficiency (WUE) of maize largely remain unknown. A three-year field experiment was conducted at the Zhuanglang Experimental Station, Gansu Academy of Agricultural Sciences, located in the semiarid region of the Loess Plateau, Northwest China during 2014-2016.

[IHA detection results of outpatients in schistosomiasis clinic, 2005-2014].

Objective: To understand the changes of positive rates of IHA detections of outpatients in schistosomiasis clinic.

Results: The data of IHA detections of outpatients in schistosomiasis clinic in Hubei Provincial Center for Disease Control and Prevention were collected and analyzed statistically from 2005 to 2014.

Results: A total of 7 113 outpatients were detected by IHA test, and 547 of them were positives with a positive rate of 7.
