摘要
为了有效降低板栗空苞率、提高产量2004—2006年在镇安县进行了喷施硼肥试验。结果表明：展叶、盛花、末花期，在栗树叶面喷0．2％～0．4％的硼砂溶液3次，可使板栗空苞率降低26％；春季萌芽前每平方米树冠投影面积施硼15g，可使板栗空苞率降低29．1％，增产45．7％。
The formation of empty shell chestnut is one most direct reasons of effecting the yielcl. In order to effectively reduce the empty shell rate,increase the yield and income of chestnut famers, the experiment of spraying boron fertilizer was carried out at the Zhenan during 2004-2006. The result showed that the empty shell rate reduced by 26% through spraying 3 times of boron fertilizer solution with the concentration Of 0. 2%-0.4% on the leaves at the period of leaf-expansion, full bloom, and end bloom; The empty shell rate reduced by 29.1% and the yield increased by 45.7% through spraying 15 g · m^-2 （canopy cover） before germination in spring .
