枣树花芽当年分化、多次分化、边生长边分化 ,分化持续期长 ,造成物候期重叠 ,各器官对养分竞争剧烈 ,在短期内消耗大量营养物质 ,导致落花落果严重 ,收果率仅 1%～ 2 %。提高枣树坐果率的措施 ,除了加强土、肥、水管理 ,改善树体的营养状况外 ,提高叶片的光合效能 ,调节生长与
Differentiation of jujube flower buds, multiple differentiation, while the edge of growth differentiation, differentiation of a long duration, resulting in phenophase overlapping, intense competition for nutrients in various organs, consuming a large number of nutrients in the short term, leading to serious drop, fruiting rate of only 1 % ~ 2%. In addition to strengthening the management of soil, fertilizer and water, and improving the nutritional status of the tree, the measures to improve the fruit setting rate of jujube tree are to improve the photosynthetic efficiency of leaves and to regulate the growth and
