Method for enriching carrot with multi-trace elements

[0020] In this embodiment, after 7 days of conventional site preparation, applying sufficient basal fertilizer, sowing, thinning, and finalizing 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 amount of application was 300-400ml / per plant; After 10 days, apply an appropriate amount of trace element nutrient solution diluted 500 times with clean water around the root of each carrot seedling again, the application amount is 400-500ml / per plant; 10 days later, spray the trace element nutrient solution diluted 500 times with clean water once After 10 days, the foliage sprayed once with a trace element nutrient solution diluted 400 times with clear water; Foliar spraying should be done evenly on the upper and lower leaves as far as possible, and the amount of spraying should be no dripping or a small amount of dripping. Others are managed as usual, that is, carrots r

[0024] This embodiment is on the basis of embodiment 1, reducing the foliage spraying of 400 times of trace element nutrient solution dilution once, all the other are the same as embodiment 1.

[0025] The carrots harvested in this example have an average increase of 10.7% in cultivation yield compared with the conventional method, and the roots of carrots are rich in various trace elements: germanium content 3.82 mg / kg; selenium content 1.35 mg / kg; zinc content 8.49 mg / kg; Chromium content: 0.62mg / kg; Vanadium content: 0.57mg / kg.

[0027] In this embodiment, after 7 days of conventional site preparation, application of sufficient base fertilizer, sowing, thinning, and finalizing of seedlings, an appropriate amount of trace element nutrient solution diluted 600 times with clear water is applied around the root of each carrot seedling, and the amount of application is 300-400ml / per plant; After 10 days, apply an appropriate amount of trace element nutrient solution diluted 500 times with clear water around the root of each carrot seedling again, and the application amount is 400-500ml / per plant; other things are managed according to conventional methods, that is, the harvest is rich in germanium, selenium, and zinc. , chromium, vanadium and other trace elements of carrots;

[0028] The carrots harvested in this example have an average increase of 6.8% in cultivation yield compared with the conventional method, and the roots of carrots are rich in various trace elements: germanium content 1.26 mg / kg; sele
