Example Embodiment
[0019] Example 1
[0020] In this example, after 7 days of conventional soil preparation, application of sufficient base fertilizer, sowing, thinning, and setting seedlings, an appropriate amount of trace element nutrient solution diluted 750 times with clear water was applied around the root of each carrot seedling, and the applied amount was 300-400ml / each plant; After 10 days, apply an appropriate amount of trace element nutrient solution diluted 500 times with clear water to the roots of each carrot seedling again, and the application amount is 400-500ml / each plant; after 10 days, spray the trace element nutrient solution diluted 500 times with clear water once again ; 10 days later, the foliar spray applied the trace element nutrient solution diluted 400 times with clear water once; after 10 days, the foliar spray applied the trace element nutrient solution diluted 300 times with clear water once. Foliar spraying try to make the upper and lower leaves spray evenly, and the s...
Example Embodiment
[0023] Example 2
[0024] In this example, on the basis of example 1, the foliar spray of a 400-fold dilution of the trace element nutrient solution is reduced, and the rest are the same as in example 1.
[0025] The yield of the carrots harvested in this example was increased by 10.7% on average compared with the conventional cultivation method, and the carrot root pieces are rich in various trace elements: germanium content 3.82mg / kg; selenium content 1.35mg / kg; zinc content 8.49mg / kg; Chromium content: 0.62mg / kg; vanadium content: 0.57mg / kg.
Example Embodiment
[0026] Example 3
[0027] In this example, after 7 days of conventional soil preparation, application of sufficient base fertilizer, sowing, thinning, and setting seedlings, an appropriate amount of trace element nutrient solution diluted 600 times with clean water was applied around the root of each carrot seedling, and the applied amount was 300-400ml / each plant; After 10 days, apply an appropriate amount of trace element nutrient solution diluted 500 times with clean water around the roots of each carrot seedling again, and the amount of application is 400-500ml / each plant; others are managed according to conventional methods, namely harvesting rich in germanium, selenium, and zinc , Chromium, vanadium and other trace elements carrots;
[0028] The yield of the carrots harvested in this example was increased by 6.8% on average compared with the conventional cultivation method, and the carrot roots were rich in various trace elements: germanium content 1.26mg / kg; selenium content...
