摘要
采用大田与盆栽的方法 ,研究了粉煤灰改良砂姜黑土对小麦生长发育的影响 .结果表明 ,粉煤灰改良砂姜黑土能促进小麦根系的生长、幼穗分化和分蘖的消长 ,提高了分蘖质量、小穗可孕率和产量 .粉煤灰搀和量以 2 4× 10 4 kg·hm-2 的效果为好 .
Through pot and field experiment,a study was conducted on the effects of Shajiang black soil amended by coal fly ash on growth and development of winter wheat.The results showed that Shajiang black soil amended by coal fly ash could promote development of root system and differentiation of young panicle,and raise the transforming rate of tillers,pregnant rate of young panicle and yield of wheat.Among all the treatments,24×10 4 kg·hm -2 of coal fly ash applied was the best.
