对不同品系爱玉子(Ficus awkeotsang)的繁殖系统进行了研究。推算表明:爱玉子栽培的雌、雄株数量配植比例可以从目前的4~5∶1提高到23~24∶1,以使传粉小蜂种群达到合理密度,提高结实率和成虫瘿率,增加单位面积雌株的栽培数量,提高爱玉子单位面积产量,增加土地栽培效益。比较爱玉子不同品系雌、雄花序的B期(雌花期)与雄花序的D期(雄花期)花序数量变化及持续时间,结果表明:栽培爱玉子雄花序D期时长约1个月,而雌、雄花序的B期时长却是2~3个月,B、D期不能完全重叠,导致B期花序因没有小蜂传粉(或产卵)而脱落。因此建议对雄株的B期花序进行人工引蜂的方法修复小蜂种群,从而延长雄性品系D期时长;而雌、雄品系配植模式应为1∶2~4,即1个雌株品系与2~4个D期依次衔接的雄株品系配植。福建省的爱玉子栽培急需引进和选育D期早熟和晚熟的雄性品系。
The reproductive systems of different strains of Ficus awkeotsang were studied. The results show that the proportion of male and female plants can be increased from 4: 5: 1 to 23: 24: 1 at present, so that the population of pollinating wasps reaches a reasonable density and the seed setting rate and adult rate are increased. Increase the number of female plant per unit area to increase the yield per unit area of love jade, increase the benefits of land cultivation. The results showed that the male inflorescences of Ayuzai were about 1 month in length when compared with those of the male ones of male and female inflorescences, and the number of male inflorescences in stage B (female inflorescences) and male inflorescences (male inflorescences) Female and male inflorescences B period is 2 to 3 months, B, D period can not be completely overlap, resulting in B inflorescences because no small pollination (or spawning) and fall off. Therefore, it is suggested that the artificial inflorescence of B-stage inflorescences of male plants should be used to repair the small-bee population so as to prolong the D-phase duration of male lines. The female and male lines should be planted in a ratio of 1: 2-4, ie, 1 female And 2 to 4 D phase in turn linked to male lines planted. Fujian Province, love jade cultivation in urgent need of introduction and breeding of D-phase early maturing and late-maturing male lines.
