摘要
以寒富苹果树为试材,通过实验室常规分析方法对结果叶、营养叶的营养物质含量(5月24日至9月30日)进行了研究,确定了果树对各种营养元素吸收、转运和分配的规律,旨在为合理施肥提供依据。结果表明,营养叶叶重在6月12日至7月3日增加得最快,结果叶叶重在5月24日至6月12日增加得最快,结果叶的生长早于营养叶。果树的需肥时期为5月24日至7月3日、8月4日至9月30日,为保证果树的正常生长发育,应及时补充果树需要的养分,所以应在5月24日之前和8月4日之前施肥。
Hanfu apple trees were used to study the mineral content of leaves and accumulation dynamics to determine the absorption,transport and distribution of various minerals of fruit,and provide the basis for rational fertilization.Results showed that the weight of nutrition leaves increased fast during June 12th and July 3rd.Weight of fruiting leaves increased fast during Mar 24th and June 12th.Fruiting leaves grew earier than the nutrient leaves.The demand period for fertilizer on fruit trees was from May 24th to July 3rd,August 4th to September 30th.For its normal growth and development,nutrient should be timely supplied for fruit trees.The fertilization application should be conducted before May 24th and before August 4th.
