AI Technical Summary

Benefits of technology

This patented technology allows researchers to study how sugars can affect plants' growth without adding too much nitrogen or other substances that could harm their health. By doing this they learn about the impacts caused by these factors during water culture systems like those described earlier.

Problems solved by technology

The technical problem addressed by this patented patents relates to improper or insufficient supply of certain substances such as sugars (sugarcane), which may lead to poor health conditions like heart disease due to lack of these important mineral components needed during production.

Embodiment 1

[0020] A phosphorus-deficient nutrient solution for the nutrient content experiment of sugar orange seedlings is divided into: Ca(NO3)2·4H2O: 930-950mg / L, KNO3: 145-165mg / L, KCl: 70-95mg / L according to the concentration and dosage components. L, MgSO4 7H2O: 270-280mg / L, EDTA-FeNa 3H2O: 18-25mg / L, Na2B4O7 10H2O: 15-20mg / L, MnSO4 H2O: 1-2mg / L, ZnSO4 7H2O: 0.15- 0.25mg / L, CuSO4·5H2O: 0.05-0.1mg / L, (NH4)6Mo7O24·4H2O: 0.01-0.03mg / L.

[0021] Further, the pH value of the phosphorus-deficient nutrient solution should be controlled at about 6.0. If the pH value does not meet the requirements, use 1mol / L H 2 SO 4 Or NaOH adjustment, and the temperature of the phosphorus-deficient nutrient solution should be controlled at 12-30 ℃, if it is higher or lower than this temperature range, the phosphorus-deficient nutrient solution should be cooled or kept warm.

[0022] Further, the dissolved oxygen concentration of the phosphorus-deficient nutrient solution should be controlled above 4-5m...

Abstract

The invention discloses a phosphorus deficiency nutrient solution for measuring nutrient content of sugar orange seedlings and a preparation method thereof. The phosphorus deficiency nutrient solutioncomprises 930-950mg/L of Ca(NO3)2.4H2OL, 145-165mg/L of KNO3, 70-95mg/L of KCL, 270-280mg/L of MgSO4.7H2O, 18-25mg/L of EDTA-FeNa.3H2O, 15-20mg/L of Na2B4O7.10H2O, 1-2mg/L of MnSO4.H2O, 0.15-0.25mg/Lof ZnSO4.7H2O, 0.05-0.1mg/L of CuSO4.5H2O and 0.01-0.03mg/L of (NH4)6Mo7O24.4H2O. The phosphorus deficiency nutrient solution is easy to use in the test on sugar orange and the phosphorus deficiencysymptoms of the sugar orange seedlings can be observed. The symptoms comprise that old leaves are changed from dark green into bronze, have poor gloss and produce necrosis and novel leaves are small,thick green and dark and have slender branch tips. Through the phosphorus deficiency nutrient solution, the influence produced by phosphorus deficiency on citrus morphological characteristics and endogenous hormones of plants under hydroponic conditions is researched, the nutritional deficiency symptoms of citrus can be timely diagnosed and the effect of citrus flower and bud differentiation is determined. The phosphorus deficiency nutrient solution provides the theoretical basis for a series of balanced fertilization measures.
