| 摘 要： | 本文研究了微量元素硼与板栗空苞率的相互关系。试验表明,板栗空苞率与土壤中有效硼含量相关,当土壤中含硼量高于0.48ppm以上时,空苞率降低至8％以下,硼含量低于0.094ppm时,空苞率达80％以上。对板栗树的叶片和花喷施0.15～0.25％微量元素硼,可使板粟空苞率降低23～32％,明显提高产量。喷施次数以2～3次为宜,喷施时期选择在板栗展叶期、盛花期、末花期进行,但以盛花期喷施效果最好。

| Abstract: | Descrbes the effect of spraying of micronutrient boron in reducing the hollow bract ratio of Castanea mollissima Bl., It was found that when the effective boron content in soil is above 0.48ppm, the hollow bract ratio of Castanea mollissima Bl.is less than 8%. But when the boron content in soil descreased to 0.064ppm, the hollow bract ratio will increase to 80% or above. The hollow bract ratio of Castanea mollissimaB1. can be reduce 23-32% by foliar and floral spraying of 0.15-0.2% boron 2-3 times during the full blossom stage. |
