摘要: 为探索磷石膏和有机肥对盐碱地糜子产量和叶片生理特性的影响,本试验以粘丰5号和内糜8号为试验材料,本研究以‘粘丰5号’和‘内糜8号’为试验材料,在大田条件下设置了4个处理,包括磷石膏(60 t/hm2)、有机肥(187.50 t/hm2)和磷石膏有机肥混合(60 t/hm2磷石膏+187.50 t/hm2有机肥),以盐碱地未改良作为对照。结果表明:有机肥和磷石膏混合处理对两个糜子品种叶片糖分积累调控效果存在差异,对粘丰5号开花后14d的叶片蔗糖含量、可溶性糖含量促进效果较优,而对内糜8号开花后21d的叶片蔗糖含量、可溶性糖含量促进效果较优;粘丰5号整个测定时期叶片淀粉含量在磷石膏和有机肥混合处理、有机肥处理下基本上低于磷石膏处理,而内糜8号叶片淀粉含量在开花后7d~21d以磷石膏处理为最高,之后,以磷石膏处理为最低;开花后42d叶片可溶性蛋白含量在粘丰5号中以磷石膏有机肥混施处理最高,而在内糜8号中以单施有机肥处理为最高。三种盐碱地改良措施均能够增加糜子产量,其中以磷石膏和有机肥混合处理下的增加效果优于单施磷石膏和单施有机肥处理。

Abstract: In order to explore the effects of phosphogypsum and organic fertilizer on yield and leaf physiological characteristics of broomcorn millet in saline alkali soil, this study with the ‘Nianfeng 5’ and ‘Neimi 8’ as the experimental materials, under the field condition set up four treatments, including phosphogypsum (60 t/hm2), organic fertilizer (187.50 t/hm2) and phosphogypsum mixed organic fertilizer (60 t/hm2 phosphogypsum + 187.50 t /hm2 organic fertilizer), and the saline-alkali soil was not improved as a control. The results showed that the regulation effect of phosphogypsum mixed with organic fertilizer on leaf sugar accumulation of two broomcorn millet varieties were different. Compared with other two treatments, leaf sucrose content and soluble sugar content of ‘Nianfeng 5’ under the mixed treatment were higher on 14d after flowering, but leaf sucrose content and soluble sugar content of ‘Neimi 8’ were higher on 21d after flowering. Leaf starch content of organic fertilizer and mixed treatments in the whole test period was lower than that of phosphogypsum treatment in ‘Nianfeng 5’. However, leaf starch content from 7d to 21d after flowering was the highest, after that it was the lowest under phosphogypsum treatment in ‘Neimi 8’. Leaf soluble protein content was highest in ‘Nianfeng 5’ under mixed treatments and in ‘Neimi 8’ under organic fertilizer on 42d after flowering. The three amelioration treatments were able to increase the yield of broomcorn millet, and the increased effect of mixed treatment was better than that of phosphogypsum and organic fertilizer treatments.
