甘肃景泰黄冠梨鸡爪病与果肉钙营养关系的研究

Study on Relationship between Jizhua Disease and the Calcium Content in Caro of Huangguan Pears

黄冠梨喷施不同钙制剂的试验结果表明,果面喷施3 g/kg氯化钙、1 000倍氨基酸钙、700倍CA2000钙宝和1 200倍翠康钙宝4种不同钙肥处理的黄冠梨果肉全钙含量明显增加,Ca/N比值提高,鸡爪病发病率明显降低;黄冠梨果肉全钙含量、Ca/N比值与鸡爪病的发病率呈显著的负相关。

The result of experiment that Huangguan pears were sprayed by different kind of calcium nutrient, showed that the calcium content and Ca/N were higher in caro of Huangguan pears sprayed by nutrient solution of 3. 0 g/kg CaCl2, amino acid calcium of 1 000 times, CA2000-calcium of 700 times and Cuikang calcium of 1 200 times than that of other treatments, while the rate of the disease was lower than that of other treatments respectively. The rate of the disease was negatively correlative to the calcium content and Ca/N in caro of Huangguan pears.
