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.

The climate of Gansu turned to be overall warming-drying and partly warming-wetting since 1986. In contrast to that of 1960, the average annual temperature had raised by 1.1°C with the average annual precipitation decreased by 28 mm correspondingly, which made the arid region expanded southward by 50 km in 2010.

Taking soybean cultivar Jindou 23 as test object, a field experiment was conducted at the Zhenyuan experimental station of Gansu Academy of Agricultural Sciences to study the effects of various plastic mulching treatments on the soil moisture and temperature and soybean grain yield on a semiarid dryland of Northwest China. Four treatments were installed, i. e.

2-(4-Phenyl-3H-1,5-benzodiazepin-2-yl)phenol.

In the title compound, C(21)H(16)N(2)O, the dihedral angle between the pendant aromatic rings is 74.2-(1)°..

(5-Bromo-2-hydroxy-phen-yl)(phen-yl)methanone.

In the title compound, C(13)H(9)BrO(2), the mol-ecular conformation is stabilized by an intra-molecular O-H⋯O hydrogen bond. In the crystal structure, weak inter-molecular C-H⋯O hydrogen-bonding inter-actions link the mol-ecules into chains along the c-axis direction.
