Biotech crops expressing Bacillus thuringiensis (Bt) insecticidal crystalline (Cry) proteins became commercially available in the US in 1996. In 2006, 19 million ha of Bt corn were planted worldwide, which resulted in a significant reduction in the amount of chemical insecticides that are necessary to control agricultural pests. Despite the high adoption rates of this novel insecticide, little ...

Atmospheric liquefaction technology has been used widely and is an effective way of biomass component utilization. In this paper, the liquefied products obtained from corn stalk using polyhydric alcohols 1,2-propanediol (PG) mixed diethylene glycol (DEG) through acid catalysis under atmosphere pressure were characterized by various analytical technologies. The results indicated that 39 kinds or...

After corn mechanical harvest in autumn the cold region of northeast China, straw mulching leads to high soil topsoil water content and slow ground temperature rise spring sowing season, which may result a no-tillage planter being unable operate time, delayed date, poor seedling emergence quality, low grain yield. Based on problems moisture season conservation tillage with mulching, an experime...

Effects of two different modified treatments were investigated relative to the chemical and mechanical properties pretreated corn stalk particles their composites prepared with a lignosulfonate (ML) binder. Corn (CP) first by treating oxalic acid in ultrasonic conditions (pretreated particles, PCP). These then treatment either laccase-vanillin system ultrasound (LU) or polyethylenimine-glutaral...
