Water and nutrients are the basic requirements for crop growth, which are mutually interacting and restricted. This paper studied winter wheat (wheat breed: Ji wheat 22) on changes in soil nutrient leaching in the regulation measures of water and fertilizer (two irrigation methods: traditional irrigation (A) and water-saving irrigation (B); three fertilization factors: no fertilization (CK), traditional fertilization (FC) and optimized fertilization (FO)). The results showed that under the diffe...

An appropriate rice-based (ARB) biomass gasifier was designed and de-veloped for farmers’ use. The gasification properties of rice-based biomass were determined before doing the design. The gasifier was built using salvage petrol drums, metal bars and concrete as primary construction materials. It has a 30 cm-diameter reactor insulated with refractory cement. A 10 cm-o cross flow scrubber with 30 cm-thick packed-bed filter is used
