钙素是果树生长所必须的营养元素之一。它既是细胞核的重要组成成分,又在代谢中起重要作用,碳水化合物的转化,氨的代谢都离不开钙。果树缺钙不仅会影响树体发育,也会影响果实品质,特别是苹果缺钙易得苦痘病。辽宁省微酸性和酸性土壤面积较大,特别是南部沿海地区许多果园,土壤基本是微酸甚至酸性,果树生理病害比较严重,不仅影响苹果产量的提高,也影响果实品质的改善。
Calcium is one of the necessary nutrients for the growth of fruit trees. It is not only an important component of the cell nucleus, but also play an important role in the metabolism, carbohydrate transformation, ammonia metabolism can not be separated from calcium. Calcium deficiency of fruit trees will not only affect the development of trees, but also affect the quality of fruits, especially for the easy-to-get bitter pox disease of apple calcium deficiency. Liaoning Province has a slightly acidic and acidic soil area, especially in many orchards in the southern coastal areas. The soil is slightly acidic or even acidic. The physiological disease of fruit trees is rather serious, which affects not only the increase of apple yield but also the improvement of fruit quality.
