| 摘 要： | 采用盆栽试验,通过添加粉煤灰和牛粪对煤矸石污染土壤进行改良,并研究了不同改良措施对大豆生长、光合特性和产量的影响。结果表明,添加粉煤灰0.07 kg.kg-1(T1)、添加牛粪0.07 kg.kg-1(T2)、添加粉煤灰和牛粪各0.07 kg.kg-1(T3)3种土壤改良措施对大豆的株高、叶面积和单株根瘤数均有显著影响,不同生育期株高、叶面积和单株根瘤数均表现为T3>T2>T1>CK。在花期和鼓粒期,3种土壤改良措施下大豆的叶绿素含量和光合速率均显著高于对照,且T3处理显著高于T2和T1。与对照相比,不同土壤改良措施对大豆的单株荚数、百粒重、单株粒重和产量均有显著影响,T3、T2和T1处理的大豆产量较对照分别提高68.47%、40.99%和30.63%。 |

| Abstract: | In a pot experiment using coal gangue contaminated soil with fly ash and dairy manure dung,separately or in combination,as soil amendment,soybean was planted to study effects of the amendments on the growth,photosynthesis and yield of the plant.Four treatments were designed: CK(control),Treatment T1(fly ash),Treatment T2(dairy manure),T3(fly ash and dairy manure in combination).Results show that all 3 treatments improved soybean in plant height,leaf area and number of root nodules,but followed the order of ... |
