Tolerance of Sweet corn (zea mays) Hybrids to RPA 201772

摘要

Field studies at Arlington WI, and LeSueur, MN, Were conducted in 1996 and 1997 to evaluate tolerance of six sweet corn hybrids to RPA 201772 applied preemergence at 79 to 210 g/ ha. Both years the most sposite propellant having the nominal composition 84/100 RDX + 16/100 HTPB has been investigated experimentally. The following steady combustion parameters were collected over The pressure range 0.1 to 8.21 Mpa: burn rates, burn surface temperatures, thermal gradients, heat release in The condensed phase, heat feedback from the gas phase, first and second (or final) flame temperatures. In General, for the tested RDX.HTPB mixture, values smaller than the corresponding AP.HTPB parameters are Found, while the burning rate pressure exponent is larger.
