螯合稀土-硼对苎麻产量和品质影响初探

试验于1987年和1988年在本所试验站进行。结果表明,无论是壮龄麻还是在新栽麻上,喷施适量螯合稀土-硼均能增加原麻产量,提高纤维支数,并且以1/10~4 RE-1/10~3B处理效果较好,适量的螯合稀土-硼能增加叶绿素含量、可溶性糖含量,总光合速率,净光合速率和呼吸强度,从而协调了产量和品质各构成因素之间的关系,使产量增加,品质得到改善,因此,在苎麻生产中应用螫合稀土-硼是一种有效的增产增质措施。

A PRELIMINARY PROBE OF THE EFFECT OF CHELATE-RARE-EARTH-BORON ON YIELD AND QUALITY OF RAMIE

Experiments of application of chelate-rare-earth boron to ramie plants werecarried out in 1987 and 1988 in the Experimental Farm, Ramie Research Institute, HunanAgricultral College. The results show that both newly planted and well-growing ramie plantshave increased yield and yarn number. The 1 / 10~4 RE-1 / 10~3 B solution treatment has gi-ven the best results. Proper amount of chelate-rare-earth-boron increases the content ofchrolophyll, solusugar; raises the rate of total and net photosynthesis and the intensity ofrespiration, thus improves the relationship brtween the factors of yield and quality. It can beconcluded that application of chelate-rare-earth-boron to the production of ramie is an ef-fective way for higher yield and better quality.
