| 摘 要： | 采用板栗化学疏雄增产技术,喷用"板栗化学疏雄剂",促使大量雄花提早脱落,降低树体营养消耗,从而达到板栗丰产目的。试验表明:当混合花序长度在2cm时,喷用药剂稀释度为1000～1200倍的化学疏雄剂增产效果最为显著,其喷药成本投入与产出比在1∶5以上,最高可达1∶6 3,可净增效益2110～2723元·hm-2。

| Abstract: | The experiment showed that the effect of increasing production was most significant with spraying 1 000～1 200 times of dilute solution of male flower thinning chemical agent when the mixed inflorescence length reached 2 cm,the input-output ratio of cost of spraying the agent was over 1∶5,and might reach 1∶6.3 to the maximum,the net increase benefit might reach 2 110～2 723 yuan·hm~(-2). |
