Embodiment 1

[0033] Embodiment 1: A plant fermented extract that prevents rice from absorbing heavy metals is mainly made by mixing raw materials in the following weight ratios: Gorgon fruit 13kg, Digupi 10kg, Wujiapi 8kg, Cordyceps sinensis 0.1kg, Reed root 20kg, carapace Vegetarian 0.3kg, flavescens 5kg, pollen 6kg, rice germ 20kg, hirudin 0.2kg, selenium yeast 0.15kg, licorice 5kg, dilongsu 0.2kg.

[0034] The specific preparation method is as follows:

[0035] (1) Select the best raw materials;

[0036] (2) Mix and pulverize all raw materials, pass through a 30-mesh sieve, and place in a fermenter, wherein the selenium yeast is dissolved in deionized water and then added with water;

[0037] (3) Add deionized water to the fermentation tank and stir evenly. The amount of deionized water added is 2.5 times the total weight of raw materials. Ferment and age at 37°C for 21 days, and the material is muddy;

[0038] (4) Add deionized water into the fermentation tank and stir, adjust the vi...

Abstract

The invention belongs to the technical field of rice planting, and particularly relates to a plant fermentation extract for preventing rice from absorbing heavy metals and a preparation method of the plant fermentation extract. The plant fermentation extract for preventing rice from absorbing heavy metals is mainly prepared from the following raw materials in parts by weight through fermentation, extraction and powder preparation: 13 to 15 parts of semen euryales, 10 to 12 parts of cortex lycii radicis, 8 to 10 parts of cortex acanthopanacis, 0.1 to 0.2 part of cordyceps sinensis, 20 to 22 parts of rhizoma phragmitis, 0.3 to 0.5 part of chitin, 5 to 7 parts of radix sophorae flavescentis, 6 to 7 parts of pollen, 20 to 21 parts of rice germ, 0.2 to 0.3 part of hirudin, 0.15 to 0.2 part of selenium yeast, 5 to 6 parts of liquorice root and 0.2 to 0.25 part of lumbricin. The raw materials are easy to obtain, the preparation process is stable, rice is effectively prevented from absorbing heavy metal in soil, the heavy metal content of rice is reduced, the soil structure is improved, rice growth is promoted, the rice nutritional value is increased, and the fertilizer is suitable for wide application and popularization.

Description

technical field [0001] The invention belongs to the technical field of rice planting, in particular to a plant fermented extract that prevents rice from absorbing heavy metals and a preparation method thereof. Background technique [0002] Rice is the main food crop in my country, but the heavy metal content in rice is increasing year by year. This is mainly because the rice planting soil is polluted by heavy metals. After the heavy metals in the soil are absorbed by rice, they will eventually enter the human body through the food chain, endangering human health. [0003] At present, although the heavy metal content of rice is still in a relatively safe range, measures still need to be taken to reduce the heavy metal content of rice. The commonly used measures to reduce the heavy metal content of crops such as rice are to apply inorganic adsorbents such as lime and sulfur powder to the soil. Inorganic adsorbents can react with heavy metals to form insoluble substances, there...
