[Objectives]The best fertilization model was filtrated in order to provide a reference for pepper cultivation. [Methods]The environment and economic benefits and the distribution of nitrogen(N),phosphorus(P) in soil and pepper of several treatments(Treatment 1:conventional fertilization;Treatment 2:optimization of reducing herbicide;Treatment 3:optimization of reducing pesticide;Treatment 4:integration of water and fertilizer) were compared in order to filtrate a better fertilization model. [Results]N,P decreased layer by layer in different depth of soil,with the times of fertilization,and the accumulation of N and P in different depth of soil increased,the downward leaching of which was not obvious. In the growth of pepper,the growing rate of accumulation of N,P in pepper in the fourth treatment was higher than that in the other three treatments. The total nitrogen(TN),total phosphorus(TP) contents in pepper were significantly higher than those in the other three treatments in harvest time,which promoted the absorption and utilization of nitrogen and phosphorus. The yield of the fourth treatment was 79.37%,41.25%,16.49% significantly higher than that of the other three treatments,respectively. The partial factor productivity of applied N(PFPN) of the fourth treatment was 135.33%,85.33%,52.84% significantly higher than that of the other three treatments,respectively. The input-output ratio(VCR) of the fourth treatment was 3.23 produced the best economic benefit,which was 28.17%,31.30%,16.61% significantly higher than that of the other three treatments,respectively. The emission flux CO2,N2O of first treatment and the second treatment were higher than those of the other treatments. There were environmental risks about greenhouse effect under the conventional fertilization,which was to be confirmed further. [Conclusions]The results above suggest that the fourth treatment(integration of water and fertilizer) brings better environment and economic benefits among these treatments. [ABSTRACT FROM AUTHOR]

A cobalt salt catalyst was synthesized with the aim of decreasing the decomposition temperature of sodium chlorate. The composition, assembly structure and decomposition behaviors of oxygen candle were investigated by consiclering the influences of catalyst, solvent, binder, chlorine suppression agent and pressing process. Portable metal-free oxygen candle was fabricated using a comprehensive manufacturing process. The oxygen candle can burn at the temperature lower than the melt temperature of sodium chlorate, of which the releasing rate of oxygen is 0-5 L oxygen per minute and the release amount of chlorine is less than 0.001 mg/L. Catalyst and pressing process are key factors for the manufacturing of low temperature combustible sodium chlorate oxygen candle. [ABSTRACT FROM AUTHOR]
