The invention discloses a leaf
nutrition diagnosis method of raspberry. The leaf
nutrition diagnosis method comprises following steps: 1, sampling; 2, leaf
sample processing, wherein the collected samples are washed with deionized water,
excess water is removed via adsorption,
enzyme deactivation,
drying,
grinding, and sieving are carried out, and samples which are subjected to detection using an atomic absorption spectrophotometer are also processed via dry
ashing and acidification; and 3, measuring of leaf mineral element content. According to the step of sampling,
diagonal method is adopted in sampling of square orchards, and broken line method is adopted in sampling of rectangular orchards, five sampling points are selected, four plants with
normal growth conditions are selected at each point, three leaves of each
plant are collected, wherein mature leaf collection parts are the 7th to 12th nodes of current-year branches, young leaf collection parts are the top parts of current shoots, and preferably, in Heilongjiang Province, summer fruit variety sampling time is determined at the early ten days and the middle ten days of August, and autumn fruit variety sampling time is determined at the middle ten days of June. The invention also discloses a raspberry
nutrition diagnosis standard specific scope. The leaf nutrition diagnosis method of raspberry and the raspberry nutrition
diagnosis standards are established so as to provide raspberry production and fertilization with guidance basis.
