ORGANIC MATERIAL TO IMPROVE WEED-CONTROLLING FUNCTION AND ENVIRONMENTAL FUNCTION

摘要

PROBLEM TO BE SOLVED: To avoid the use of herbicide giving the greatest neckpoint for maker liability in response to the food safety and security demanded by people, and fulfilling the cost as well as effectiveness.;SOLUTION: A trypsin inhibitor contained in raw soybean has a function to inhibit enzymatic activity and the activity is increased by pulverizing the raw soybean. The weed-controlling efficiency is improved by the growth difference caused by the synergistic effect of the trypsin inhibitor and the rooting inhibiting function of an organic acid in rice bran used in combination with the agent. Further, an active environmental protecting effect is developed by the addition of a material having the function of fulvic acid. The pulverization of raw soybean is carried out either by a method to roughly crush the soybean, quickly freeze the crushed soybean, substitute with nitrogen gas in a weakly evacuated thawing drier chamber having a far infrared radiation function, and carry out the thawing evaporation and drying to the essential water content in a temperature zone at or below the freezing point, or a method to dry the soybean in an opened thawing drier chamber with cold air at or below the freezing point using a fluidizing function to induce thermal loss phenomenon and pulverize the dried product with a pulverizer having a new mechanism.;COPYRIGHT: (C)2007,JPO&INPIT
