摘要
为有效利用盐碱荒地,发展适合生长的能源植物,测定了16种植物的植株含油量和8种植物的抗性生理指标。结果显示:野生蓖麻含油量(13.9%)最高,其次分别是小蓟(12.5%)、萝摩(11.2%)、地锦(10.0%)、大蓟(9.27%)、续随子(9.25%)、蒲公英(7.75%)、山苦荬(7.63%)、乳浆大戟(6.57%);8种植物的抗寒性强弱为:麻疯树、野生蓖麻>乌桕>银合欢>蒲公英、山苦荬>地锦、萝摩;8种植物的抗旱性强弱为:麻疯树、乌桕>银合欢>野生蓖麻、萝摩>地锦>山苦荬>蒲公英。综合考虑,野生蓖麻植株和种子含油量高,植株高大,抗逆性强,是有潜力的野生草本能源植物;麻疯树植株和种子含油量亦高,抗逆性最强,是有潜力的野生木本能源植物。
In order to make good use of the saline-alkaline soils and select the appropriate energy plants, the oil content of 16 kinds of plants and the physiological indexes related with resistance of 8 kinds are measured. The result showed that oil content of Ricinus communis L. is the highest, up to 13. 9%, followed by Centipeda minima (L.)A. B. et Ascher (12. 5%),Metaplexis japonica ( Thunb. ) Makino ( 11. 2 %), Euphorbia humifusa wild ( 10. 0% ), Cephalanoplos setosum (Willd.) ( 9. 27%), Kitam. Euphorbia lathyris. ( 9. 25 %), Taraxacum mongolicum Hand. - Mazz. (7.75%),Ixeris chinensis (Thunb.)Nakai(7.63%),Euphorbia esula Linn. (6.57%). The order of the iciness resistance in the 8 plants was:Jatropha curcas L. =Ricinus communis L. 〉Sapium sebiferum (L.) Roxb 〉 Leucaena glauca . Taraxacum mongolicum Hand. -Mazz = Ixeris chinensis ( Thunb. ) Nakai 〉 Euphorbia humifusa Wild. = Metaplexis japonica ( Thunb) Makino. For the drought resistance,Jatropha curcas L. = Sapium sebiferum (L.)Roxb. 〉 Leucaena glauca 〉Ricinus communis L. = Metaplexis japonica ( Thunb. ) Makino〉 Euphorbia humifusa Wild〉Ixeris chinensis (Thunb.) Nakai〉 Taraxacum mongolicum Hand. -Mazz. This suggested that Ricinus communis L. and Jatropha curcas L. may be the best potential wild energy plants because of their high oil content and good resistance.
