摘要
为了加快粉煤灰的开发利用,减少粉煤灰对大气的污染,为果树生产提供优质肥料,该试验以15a生‘富士’苹果为试材,研究了粉煤灰与鸡粪不同配比、不同堆制方法对树体生长、果实品质的影响。结果表明,粉煤灰与鸡粪混合堆制腐熟的效果要好于鸡粪单独腐熟再与粉煤灰混合的效果;田间试验表明土壤中增施250～1000kg/667m2粉煤灰均能提高苹果叶片中叶绿素的含量,增加单叶重,增加果皮中花青苷含量,降低果实中可滴定酸的含量,对提高果实品质有明显的作用。考虑到重金属在土壤中的富集及长期使用,推荐施500kg/667m2粉煤灰。
Field experiments were conducted in Beijing＇s suburb to study the effect of fly ash and organic manures combined application in a different ratio and different technics on the vegetative growth and fruit quality of Fuji＇ apple. The results showed that the composting of chicken manures and fly ash could significantly reduce the pH value of fly ash compared with the no chicken manures added in fly ash. Fly ash application could improve the Chlorophyll content and the cyaniding content and these effects were in close relation to the application rates of fly ash. According to the criteria of the quality standards for environment, the optional usage of fly ash was 500kg/667m^2.
