STUDY ON WET STRENGTH PERFORMANCE OF KENAF MULCH

Land-coverage with plastic film has brought about dramatic economic benefits to agriculture, while it has caused serious soil pollution because it is not degradable. Thus, it is a limit to the application and development of agricultural film. The use of biodegradable mulch made of cellulose fibers is an important way to resolve this problem.Mulch is used in the open air of such weather as windy, rainy, fine and cloudy .So higher dry and wet strength is required. It is best for using conifer w…

STUDY ON WET STRENGTH PERFORMANCE OF KENAF MULCH

Optimum applied technical conditions of wet strength agent for kenaf mulch were studied in this article. Breaking length, wet-dry strength ratio, tear index and burst index of kenaf mulch were measured and optimum wet strength agent was selected. The aim is to make mulch have properties of heat preservation, humidity preservation, growth prompting, biodegradation and maximum wet strength and to improve impact resistance of mulch to rainwater so as to assure growth of plant and replace plastic film.
