摘要: 采用盆栽试验法,研究了草炭和风化煤对水稻根系的α-萘胺氧化力和养分吸收的影响.结果表明,草炭和风化煤的施入,改善了盐碱土的养分供应状况,在水稻的各生育时期均不同程度地提高根系活力,增加了水稻的产量,促进了水稻对N、P2O5、K2O、CaO和MgO等养分的吸收;草炭对水稻的增产效果要好于相同数量的风化煤。

Abstract: Effects of peat and weathered coal on activity of rice root system and its nutritional absorption were studied by pot experiment.The results showed that adding peat and weathered coal improved α-naphthyl amine oxidizing activity of root system during the different growing phases of rice,ameliorated the nutrient supplying of saline-alkali soil,enhanced the yield of rice,and increased the nutritional absorption of N,P2O5、K2O,CaO,and MgO by rice.To increase productivity,peat is better than the same quantity of weathered coal.
