风沙土添加油页岩对花生生长及产量的影响

采用田间试验研究油页岩与有机肥按不同比例配施(0：1,1：1,1.5：1,2：1)对花生生长及产量的影响,试验结果表明：油页岩与有机肥配施对花生产量、农艺性状和生理指标有显著的促进作用,具有良好的氮肥作用,其中油页岩与有机肥按1.0-1.5:1配施的处理最佳,可使花生产量、果实数、双粒数、单株果重、主茎高、侧枝长分别比对照CK增加108%,86%,99%,50%,110%,86.7%；使花生叶绿素含量(SPAD)和净光合速率较CK增14.6%和89.7%。但高用量油页岩对花生植株的生长及光合性能产生一定抑制作用,因此,在实际应用过程中须注意用量,或经有效处理后再行开发利用。

Effects of adding oil shale to aeolian sandy soil on peanut growth and yield

Field experiments were conducted to study the effects of oil shale and organic fertilizer on peanut growth and yield in different proportions(0:1, 1:1, 1.5:1, 2:1). The experimental results showed that oil shale and organic fertilizer were combined. It has a significant effect on flower production, agronomic traits, and physiological indicators, and has a good effect on nitrogen fertilizer. Among them, oil shale and organic fertilizer are best treated by 1.0-1 .5:1 combination. The flower production, fruit number, double grain number, single fruit weight, main stem height, and lateral branch length can be increased by 108 %, 86 %, 99 %, 50 %, 110 %, and 86.7 %, respectively, compared to the control CK; The chlorophyll content(SPAD) and net photosynthetic rate of peanut increased by 14.6 % and 89.7 % compared with CK.
