Vegetable, wheat, cotton and melons crops were tested with the underground film technique.

The smooth muscle cells in the tunica media extend into the tunica intima.

Methods The carotid intima media thickness ( IMTc) and the brachial artery flow mediated vasodilation ( FMD ) before and after a high fat meal were measured by the high resolution ultrasound technique in 20 elderly patients with CAD and 22 healthy elderly subjects.

Results:The intimal area and medial area of the coronary artery gradually increased with .

Research and characterization of paper based cotton linter mulch film

Cotton and silk were first blended according to various ratios,followed by combing and forming nonwoven web by hydroentangling method,and then the nonwoven web was impregnated in 4% gelatin solution,thus obtained a degradable nonwoven mulch film.

The superfine quarried CaCO_3 activated by REC was applied in blown LLDPE mulching film.

The paper summarized the classification、degradation mechanism and current research and development of biodegradable mulching film, introduced the standards of biodegradation of mulching film, pointed out the current problems of biodegradable mulching film in manufacturing and the use in agricultural production, and also discuss the development trends of biodegradable mulching film.

During one day of cotton growth or cotton growth, the temperatures of the central positions below mulching film were remarkably higher than those of the lateral positions below mulching film and the temperatures in shallow soil layers increased quickly with a wide .
