摘要
通过对闽西北桃小叶症发病果园中健康植株及发病植株叶片及土壤的营养诊断,探明桃小叶症的发病原因系植株缺乏B、Ca所致。在排除农药污染因素后,桃小叶症主导病因为植株缺B,其次为缺Ca。
According to the leaf symptoms and the analysis of nutrient elements in leaf and soil, it was determined that the little leaf disease of peach in northwestern Fujian was attributed to the deficiency of Ca and B. Eliminating the pesticide pollution, the leading factor of little leaf disease was B deficiency and Ca deficiency was the secondary one.
