板栗空苞就是栗棚中没有栗子,俗称“哑巴栗子”,严重影响板栗的产量。而施用硼砂可防治空苞,提高产量。空苞的主要原因是缺硼,硼元素是受精过程中的必要元素,缺乏硼就不能正常受精,导致胚胎早期败育,而引起板栗空苞。适当地施用硼砂,对空苞果树提高产量有明显效果。春季,在栗树萌芽前,每棵施用硼砂0.2公斤后 Chestnut empty bud chestnut shed is no chestnut, commonly known as “dumb chestnut,” a serious impact on chestnut production. The application of borax can prevent empty bracts, increase production. The main reason for the empty bract is boron deficiency. Boron is an essential element in the process of fertilization. Lacking boron can not normally fertilize, resulting in early embryo abortion, causing chestnut empty bract. Appropriate application of borax, hollow-fruit trees to improve yield significantly. In spring, chestnut tree buds before each application of borax 0.2 kg
