Research method for nutrient fertilization of Gannan navel orange

Abstract

The invention discloses a research method for nutrient fertilization of Gannan navel orange. The research method comprises: collecting normal fruits at the middle-upper parts of fruiting branches outside a plant crown along four directions every one month in 90 days after a flowering period of a navel orange tree, collecting healthy leaves at the middles of the middle-upper novel tips outside a plant crown along four directions, measuring transverse diameters, longitudinal diameters and unit fruit weight of the fruits, chopping and mixing the fruits, freezing a part of the fruits in liquid nitrogen, storing the fruits in an ultra-low temperature refrigerator, measuring the total sugar, sucrose, reducing sugar, total acid and citric acid content of the chopped fruits, removing main leaf veins of the healthy leaves, drying, crushing and screening the leaves and the other part of the fruits, putting the powder into a sealing bag, measuring the contents of macroelements, trace elements, heavy metal elements and light rare earth elements in fruits, collecting soil below the plant crown and in the root zone, carrying out airing, grinding and screening on the soil, storing the soil through a sealing bag, measuring the contents of macroelements, trace elements, heavy metal elements and light rare earth elements in soil, recording data, and analyzing the relationship between sugar and acid of the fruit and soil elements. The research method provide adjustment and control measures for nutrient fertilization of navel oranges.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a research method for nutrient fertilization of Gannan navel oranges. Background technique [0002] Mineral nutrition is the material basis for the growth and development of fruit trees, the formation of yield and the improvement of fruit quality. The nutrient content of leaves reflects the nutritional status of fruit trees and is closely related to fruit quality. Ganzhou City, Jiangxi Province is the famous origin of "Gannan Navel Orange" and enjoys the reputation of "the hometown of navel orange in the world". Although Gannan navel oranges have a long-standing reputation and the sales market prospects are optimistic, in recent years, with the outbreak of citrus greening disease, a large area of ​​gardens have been destroyed and converted to production. Evaluation of fruit quality. On the other hand, in order to increase the output ratio, growers have gradually increased...
