摘要
在苎麻快速生长期喷施赤霉素,能显著提高原麻产量,增产18.11～32.73%,且连续喷施三年对苎麻地下部分无影响,一般采用30～40 ppm的浓度,于头麻中麻,二麻苗、中期,三麻苗期喷施两次,经济效益最好。
The spraying of gibberellin on ramie plants in the rapidly growing stageincreases the fiber yiber yield by 18~32%. In general, 30~40 ppm gibberellinsolution is recommended in the mid-growth stage of the first crop, in theseedling and mid-growth stages of the second crop and twice in the seedlingstage of the third crop, which results in the most economic effieiency.
