螯合稀土——硼在苎麻上的应用研究

试验于１９８７年和１９８８年在湖南农业大学试验农场进行。结果表明，无论是壮龄麻还是新栽麻，喷施适量螯合稀土－硼均能增加原麻产量，提高纤维支数，并且以万分之四稀土加千分之一硼的螯合液（１０＾－４ＲＥ－１０＾－３Ｂ）处理效果较好。适量螯合稀土－硼能增加功能叶叶绿素含量、可溶性糖含量、总光合速率、净光合速率及呼吸强度，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

An Application Study of Chelate Rare-Earth Boron in Ramie(Bochmeria nivea)

Experiments of chelate rare-earth-boron (RE-B) application to ramie plants were carried out in 1987 and 1988. The results showed that the ramie yield and fibre counts increased whether on newly planted ramie or well-growing ramie. The 10-4 RE-10-3 B solution treatment hasgiven the best response. Proper application of chelate rare-earth-boron can increase the content of chrolophyl and solusugar; raise the rate of total and net photosynthesis and the intensity of respiration in functional leaves, thus improve the yield and quality. It may be concluded that the chelate rare-earth-boron application to the production of ramie will be an effective way for higher yield and quality.
