摘要
[目的]研究茉莉花不同产量等级下不同器官养分含量关系,为提高茉莉花产量提供科学依据.[方法]通过调查、采样、测试和统计分析,对横州茉莉花不同产量等级下不同器官养分含量关系进行系统研究.[结果]高产和偏高产等级下不同器官的氮、磷、钾、铁、锰、铜、锌、硼、钼、硒含量的下限高,为产量中等等级、产量偏低和低产等级的平均含量的 1.05～3.00倍;产量偏高和高等级中,锌、铜、硒在吸收上是同步的;在产量中等等级、产量偏低和低产等级中,多数养分含量在 4 个器官中均呈显著和极显著正相关关系.[结论]茉莉花器官养分含量高是高产的基础;多数养分含量在 4个器官中均呈显著和极显著正相关关系,说明施肥的重要性;现有土壤条件下,横州茉莉花田不缺少硼和硒.
Abstract
[Objective]The aim was to study the relationship of nutrient content in different organs under different yield grades of jasmine,and provide scientific basis for improving the yield of jasmine.[Method]Through investigation,sampling,testing and statistical analysis,the relationship between nutrient contents in different organs at different yield grades of Jasmine in Hengzhou was systematically studied.[Result]The lower limit of the contents of nitrogen,phosphorus,potassium,iron,manganese,copper,zinc,boron,molybdenum and selenium in different organs at high and slight high yield grades was 1.05-3.00 times of the average contents of middle,low and slight low yield grades.The absorption of zinc,copper and selenium was synchronous in high and slight high yield grades.In the middle,low and slight low yield grades,most of the nutrient contents showed significant and extremely significant positive correlation in the four organs.[Conclusion]The high nutrient content in organs of Jasmine is the basis of high yield.Most of the nutrient contents in the four organs showed significant and extremely significant positive correlation,indicating the importance of fertilization.Under the existing soil conditions,there is no lack of boron and selenium in Hengzhou jasmine field.
