Nitrogen-deficiency nutrient solution for nutrient content experiment of sugar orange seedlings and preparation method thereof

Abstract

The invention discloses a nitrogen-deficiency nutrient solution for a nutrient content experiment of sugar orange seedlings and a preparation method of the nitrogen-deficiency nutrient solution for the nutrient content experiment of the sugar orange seedlings. The nitrogen-deficiency nutrient solution for the nutrient content experiment of the sugar orange seedlings comprises the following components in concentration doses: 430 to 460mg / L of CaCl2, 185 to 195mg / L of K2SO4, 52 to 65mg / L of KH2PO4, 270 to 280mg / L of MgSO4.7H2O, 18 to 25mg / L of EDTA-FeNa.3H2O, 15 to 20mg / L of Na2B4O7.10H2O, 1 to2mg / L of MnSO4.H2O, 0.15 to 0.25mg / L of ZnSO4.7H2O, 0.05 to 0.1mg / L of CuSO4.5H2O, and 0.015 to 0.025mg / L of (NH4)6Mo7O24.4H2O. According to the invention, the nitrogen-deficiency nutrient solution isprepared, and can be conveniently used in the experiment of the orange sugar seedlings for observing the nitrogen-deficiency symptoms in leaves of the sugar orange seedlings: old leaves are yellowishgreen and gradually whole leaves are yellowing, all the leaves of the whole seedlings yellow, new leaves are small and thin, and light green to yellow, and new shoots are thin and weak, and severe nitrogen deficiency causes the leaves to fall off, branches to die and the like. The nitrogen-deficiency nutrient solution is further convenient for staff to study the effects of the nitrogen deficiencyof the sugar orange seedlings on the morphological characteristics of citrus and endogenous hormones of plants under hydroponic conditions, so that the staff can be provided with a theoretical basisfor being capable of timely diagnosing nutritional deficiency symptoms of the citrus in production and taking a series of targeted balanced fertilization measures.

Description

technical field [0001] The invention relates to the technical field of experiments on the nutrient content of tangerine seedlings, in particular to a nitrogen-deficient nutrient solution for experiments on the nutrient content of shatang tangerine seedlings and a preparation method thereof. Background technique [0002] Tangerine is a fruit grown in the subtropical regions of southern my country. my country is also a major producer of citrus, and its planting area ranks fifth in the national fruit category. Granulated Tangerine is rich in vitamin C, calcium, fiber, a small amount of protein, fat and rich in glucose, fructose, sucrose, malic acid, citric acid, citric acid and carotene, thiamine, riboflavin, niacin, Ascorbic acid, calcium, phosphorus, magnesium, sodium and other essential elements for the human body, sugar orange has a sweet and sour taste and a warm nature. It can help digestion, eliminate phlegm and quench thirst, regulate qi and dissipate stagnation, and p...

AI Technical Summary

Problems solved by technology

[0003] However, there are few studies on the symptoms of citrus deficiency at home and abroad, and a complete set of citrus deficiency diagnosis system has not been formed. quality, therefore, those skilled in the art provide a kind of nitrogen-deficient nutrient solution and preparation method thereof for the nutrient content experiment of granulated orange seedlings, to solve the problems raised in the above-mentioned background technology
