Abstract: Scrapped propellant decomposition products (SPDP) is a new type of fertilizer in agricultural production, which comes from the product of reused scrapped propellant. In order to study the influence of SPDP on wheat under high temperature stress, the greenhouse pot test was carried out. Spectrophotometer method was used to determine the physiological indexes related to the growth metabolism and stress resistance of wheat. Result showed the different compoments of SPDP were all benefit to the growth and the high temperature resistance of wheat after anthesis. Among them, T8 test has the best effect. T1 test contained nitrogen, so it significantly increased the nitrate reductase activity, sucrose phosphate synthase activity, chlorophyll content and root activity, compared with the control. T2 test contained trace diphenylamine, which significantly improved antioxidant enzyme activity, and reduced the content of malondialdehyde. In conclusion, the SPDP was beneficial to wheat growth and improved the high temperature resistance of wheat, which could be used in agricultural production as a new kind of fertilizer with high quality and environmental protection.
