一、缺硼症状及防治 1.硼的功能硼的主要作用在于促进糖在植物体内的运输,硼能加强花粉的形成和花粉管的伸长,所以硼对植物生殖过程有促进作用,花期缺硼常引起受精不良而大量落花落果。硼还可以加强其它阳离子钾、钙、镁的吸收。近年来还发现硼与核酸的代谢有密切关系。缺硼时,核酸代谢受阻,细胞分裂和组织分化都受影响,受精过程受阻碍,子房脱落,果实变小,果面凹凸 First, the lack of boron symptoms and prevention 1. The function of boron The main role of boron is to promote the transport of sugar in plants, boron can enhance the formation of pollen and pollen tube elongation, so the role of boron on the plant reproductive process to promote the flowering of the lack of Boron often cause bad fertilization and a large number of flowers fall and fall fruit. Boron can also enhance the absorption of other cationic potassium, calcium, magnesium. In recent years, boron has also been found to be closely related to the metabolism of nucleic acids. Boron deficiency, nucleic acid blockage, cell division and tissue differentiation are affected, the process of fertilization by obstruction, off ovary, the fruit becomes smaller, the fruit surface convex
