ANALYZING METHOD OF COMPONENT OF LAWN LEAF, AND DIAGNOSTIC METHOD AND GROWING METHOD OF LAWN

摘要

PROBLEM TO BE SOLVED: To provide a method allowing even a person not an expert to easily analyze inorganic components necessary for growth of lawn in a short time, a method for diagnosing excessive or insufficient organic components by use of this analyzing method, and a method for growing lawn by fertilization based on the diagnostic data. SOLUTION: Cut lawn leaves are washed and dried to form a sample S, and the sample is analyzed for the inorganic components necessary for growth of lawn by the near infrared ray 6 of a near infrared spectral analyzer 1. The quantities of the inorganic components of the analyzed lawn leaves are compared with the quantities of the inorganic components necessary for sound growth of lawn and diagnosed, and the excessive or insufficient inorganic components are adjusted by fertilization to grow the lawn.
