Embodiment 1

[0028] Embodiment 1: a kind of method that uses selenium-enriched coated seed taro to produce selenium-enriched konjac comprises the following steps:

[0029] a.

[0030] Preparation of soaking solution: Weigh 3g of sodium selenite with a purity of more than 98% and 10g of potassium permanganate in a basin or barrel, add 1L of water first, stir to dissolve, then add 9L of water, stir evenly, and prepare 0.03% selenium Sodium Oxide-0.1% Potassium Permanganate Mixed Soaking Solution;

[0031] b.

[0032] Preparation of sodium selenite coating agent: Weigh 5g-25g of sodium selenite with a purity of more than 98%, and mix it into 50kg of lime-sulfur mixture. The lime-sulfur mixture is: quicklime: fine sulfur powder = 1:1.5, manually or mechanically Stir and mix well to become a seed coating agent, the content of sodium selenite is 100mg / kg-500mg / kg;

[0033] c.

[0034] Seed soaking: soak the dormant taro in the sodium selenite-potassium permanganate soaking solution for 3h-5h...

Embodiment 2

[0039] Embodiment 2: A kind of method that uses selenium-enriched coated seed taro to produce selenium-enriched konjac, the selenium-enriched effect of planting konjac with selenium-enriched nutrition block

[0040] After konjac is soaked in 0.1% potassium permanganate-0.03% sodium selenite solution for 2h-3h, it is coated with lime sulfur mixture with a sodium selenite content of 400mg / kg, and transplanted to the experimental field. Seed soaking and non-coating cultivation were used as controls. After the seedlings were poured, 10 were weighed respectively to measure the selenium content. The results are shown in the following table:

[0041] Table 1 The selenium-enriching effect of cultivating konjac in different soils using selenium-enriched nutrient blocks

[0042]

[0043] As can be seen from the table, the use of selenium solution soaking + selenium-enriched coating seed taro cultivation can greatly increase the selenium content of konjac. The selenium content of konj...

Abstract

The invention relates to a method for producing selenium-enriched konjak by using selenium-enriched pelleted seed konjak. The method comprises the following steps: soaking the dormancy-breaking konjak in 0.1% of potassium permanganate and 0.03% of sodium selenite solution for 2-3 h, mixing and adding plant ash coating with more than 100-500 mg/kg of the selenium content, and seeding according to the conventional method after airing. The pelleted seed konjak can be used as the selenium source of the whole growing period of the konjak, and can be planted in the selenium-enriched area and selenium-deficient area, a selenium fertilizer does not need to be sprayed on leaves during the growing period, and the selenium content of different varieties of the grown konjak is between 0.2 mg/kg and 3.0 mg/kg, the konjak with different selenium contents can be produced by changing the selenium content of a coating agent, and the method is suitable for the standardized and large-scale production of the selenium-enriched konjak. The potassium permanganate is added to the seed konjak soaking solution, and has the function of the sterilization.

Description

technical field [0001] The invention relates to a method for producing selenium-enriched konjac by using selenium-enriched coated seed taro. Background technique [0002] Selenate and selenite are the main selenium sources for the production of selenium-enriched konjac. Konjac can absorb selenate and selenite ions through roots and leaves, and form selenium-enriched konjac through transformation and accumulation into tubers. At present, selenium-enriched konjac is mainly produced by screening selenium-enriched varieties, planting in selenium-enriched areas, and applying selenium-enriched fertilizers. However, selenium-enriched areas in my country are limited, and the amount of fertilization is large, uneven, labor-intensive, and time-consuming. It is difficult to scale up and the product contains The inconsistency and instability of the amount of selenium are technical difficulties encountered in the process of popularization and application. The invention provides a technol...
