The fertilizer has been successfully used in the cultivation of edible fungi such as black fungus, ganoderma and shiitake mushrooms. The application of this fertilizer makes black fungus, ganoderma lucidum and its spore powder and shiitake mushrooms rich in germanium, selenium, zinc, chromium, vanadium and other trace elements ( See "A method for enriching black fungus with t

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...

Abstract

The invention discloses a method for enriching carrot with multi-trace elements. The method comprises at least one of the following measures: 1. spreading trace element nutrient solution around the root of each carrot seedling based on 300 to 400ml per seedling after the carrot is subjected to final singling of seedling for 7 to 10 days, wherein the trace element nutrient solution is diluted 500 to 750 times by clean water; then spreading the trace element nutrient solution to the root of each carrot seedlings seven to ten days later based on 400 to 500ml per seedling; and managing according to conventional methods, thus obtaining the carrot rich in multi-trace elements, wherein the trace element nutrient solution is the ion nutrient solution fertilizer specified by claim 1 under application number of 201210053105.4; and 2, spraying the trace element nutrient solution which is diluted 300 to 500 times by clean water for 2-3 times every 7-8 days by adopting the foliar spray method in the normal growing and increasing stage of the carrot, and the last spraying is carried out above 20 days before the harvesting time of the carrot; and managing according to conventional methods.

Description

technical field [0001] The invention relates to carrot cultivation technology, in particular to a method for enriching carrots with various trace elements. Background technique [0002] The edible part of carrots is the plump and tender fleshy taproot, which can be eaten raw or cooked. It can be used to make dishes, such as frying, boiling, and cold dressing; it can also be used for pickling and pickling. Carrot meat is fine, crisp and tender, has a special sweet taste, and contains a variety of trace elements and rich carotene, vitamin C and B vitamins. It is rich in nutrition and has good edible and medical value. It is known as "little ginseng". "The name. [0003] In order to further improve the health care value of carrots and meet the health care needs in people's daily life, useful explorations have been made on increasing the types and contents of beneficial trace elements in carrots. Chinese invention patent ZL200710070934.2 discloses a "planting method of iodine-...
