近几十年来 ,国内研究板栗空篷取得了显著成果 ,阐明了板栗空篷的成因及其防治方法。板栗空篷发生机理是 :生殖器官发育不良、授粉受精不良、总苞和子房中有机养分及矿质营养 (尤其是硼、磷元素 )水平低下等。板栗空篷防治方法有 :(1)选用优良品种 ;(2 )培养最佳的树体结构 ;(3)合理配置授粉树 ;(4)适当疏雄、疏篷 ,减少树体养分消耗 ;(5 )加强肥水管理 ,保持树体健壮生长 ;(6 )适时喷布营养液和植物生长调节剂。
In recent decades, domestic research chestnut canopies achieved remarkable results, elucidated the causes of chestnut canopies and control methods. The mechanism of chestnut airfoil is: reproductive organ dysplasia, poor pollination and fertilization, involucre and ovary organic nutrients and mineral nutrition (especially boron, phosphorus elements) low level. Chestnut airfoil prevention and treatment methods are: (1) the selection of good varieties; (2) the best tree structure; (3) the rational allocation of pollination trees; (4) proper sparse male and canopy to reduce tree nutrient consumption; 5) to strengthen fertilizer and water management, to keep the robust growth of trees; (6) timely spraying nutrient solution and plant growth regulators.
