Embodiment 1

[0034] Embodiment 1: production example of selenium-enriched tomato

[0035] Mix the nano-selenium plant nutrient, microbial fertilizer and furnace ash according to the weight ratio of 1:1:4, uniformly mix the above-mentioned nutrient with tomato seedling soil to form a selenium-rich seedling substrate with a selenium content of 1mg / kg, and spread it on the In the seedling bed or into the seedling cup. According to conventional tomato seed germination, sowing and seedbed management methods, after cultivating high-quality organic selenium-rich tomato seedlings, transfer all the selenium-rich substrates around each tomato seedling in the field border or nutrition cup to the transplanting hole when transplanting. After that, follow the conventional tomato field management, and finally harvest organic selenium-rich tomatoes. The survival rate of tomatoes and the height of the aboveground part of tomato seedlings were counted, and the results are shown in Table 1.

Embodiment 2

[0036] Embodiment 2: production example of selenium-enriched tomato

[0037] Mix the nano-selenium plant nutrient, microbial fertilizer and furnace ash according to the weight ratio of 1:4:1, uniformly mix the above-mentioned nutrient with tomato seedling soil to form a selenium-rich seedling substrate with a selenium content of 1mg / kg, and spread it on the In the seedling bed or into the seedling cup. According to conventional tomato seed germination, sowing and seedbed management methods, after cultivating high-quality organic selenium-rich tomato seedlings, transfer all the selenium-rich substrate around each tomato seedling in the field border or nutrition cup to the transplanting hole when transplanting. After that, follow the conventional tomato field management, and finally harvest organic selenium-rich tomatoes. The survival rate of tomatoes and the height of the aboveground part of tomato seedlings were counted, and the results are shown in Table 1.

Embodiment 3

[0038] Embodiment 3: production example of selenium-enriched tomato

[0039] Mix the nano-selenium plant nutrient, microbial fertilizer and furnace ash according to the weight ratio of 4:1:1, uniformly mix the above-mentioned nutrient with tomato seedling soil to form a selenium-rich seedling substrate with a selenium content of 1mg / kg, and spread it on the In the seedling bed or into the seedling cup. According to conventional tomato seed germination, sowing and seedbed management methods, after cultivating high-quality organic selenium-rich tomato seedlings, transfer all the selenium-rich substrate around each tomato seedling in the field border or nutrition cup to the transplanting hole when transplanting. After that, follow the conventional tomato field management, and finally harvest organic selenium-rich tomatoes. The survival rate of tomatoes and the height of the aboveground part of tomato seedlings were counted, and the results are shown in Table 1.

Abstract

The invention discloses tomatoes rich in organic selenium and a production method thereof. The tomatoes rich in organic selenium have an organic selenium content of 10-240 microgram / kg, with organic selenium accounting for over or equal to 80 percent of the total selenium content. The method comprises the following steps: applying selenium-rich nutrient into nursery medium or nursery ridges during tomato seedling raising phase, transplanting with soil, i.e., brining selenium-containing medium at the roots of tomato seedlings into a farmland, and finally harvesting tomatoes rich in organic selenium. The selenium-rich nutrient comprises nano-selenium plant nutrient, microbial fertilizer and boiler ash residue which have a weight ratio of (1-4): (1-4): (1-4), with a selenium content of 100-1000 mg / kg. The invention have the advantages that the tomatoes are rich in selenium, the overall selenium content is uniform, and the ratio of organic selenium in the method is improved, thereby solving the problem of selenium content stability in different batches of tomatoes in the prior art, ensuring uniform selenium content in the tomatoes, and realizing standardized scale production.

Description

technical field [0001] The invention relates to vegetables, in particular to a tomato rich in organic selenium and a production method of the tomato rich in organic selenium, belonging to the technical fields of agricultural fertilization and horticultural cultivation. Background technique [0002] Tomato, Solanaceae tomato plant. The fruit is rich in nutrition and has a special flavor. It can be eaten raw, cooked, processed into tomato sauce, juice or canned as a whole fruit. Tomato is one of the most widely cultivated and eaten fruits and vegetables in the world. In tomato cultivation agronomy, seedling transplanting planting technology is widely used. [0003] Selenium, an essential trace element for the human body, is the active center of glutathione peroxidase (GSH-Px). It has biological properties such as anti-cancer, anti-aging (anti-oxidation), improving human immunity, and antagonizing heavy metals. Selenium in the food chain mainly comes from soil. If the dis...
