Embodiment 1

[0026] Embodiment 1: a kind of method that uses selenium-enriched nutrient block to plant selenium-enriched rice, comprises the following steps:

[0027] a. Preparation of selenium soaking solution: Weigh 3g of sodium selenite with a purity of more than 98% and 10g of potassium permanganate in a basin or bucket, first add 1L of water, stir to dissolve, then add 9L of water, stir evenly, and prepare 0.03 % Sodium Selenite-0.1% Potassium Permanganate Mixed Soaking Solution;

[0028] b. Production of selenium-enriched nutrient block: take 0.5-2.0 g of sodium selenite with a purity of more than 98%, mix it into 50 kg of nutrient soil, stir and mix well to make selenium-enriched nutrient soil, and the content of sodium selenite is 100 mg / kg-400mg / kg; put selenium-enriched nutrient soil into the nutrient plate, 10g-20g per hole;

[0029] c. Seed soaking: select rice seeds that are healthy, disease-free, and mildew-free, wrap them in gauze, immerse them in the selenium soaking solu...

Embodiment 2

[0033] Example 2: A method of using selenium-enriched nutrient blocks to plant selenium-enriched rice, and the selenium-enriched effect of cultivating rice with selenium-enriched nutrient blocks

[0034] Through pot experiments, we selected selenium-enriched soil and non-selenium-enriched soil, and used selenium-enriched nutrient blocks with 200 mg / kg of sodium selenite to cultivate rice, with 3 plants per plant. After getting 10 sacks and weighing, measure the selenium content, the results are shown in the following table:

[0035] Table 1 Selenium-enriching effect of using selenium-enriched nutrient blocks to cultivate rice in different soils

[0036]

[0037] It can be seen from the table that selenium-enriched rice can be produced in selenium-enriched soil, and selenium-enriched rice can also be produced in non-selenium-enriched soil with selenium-enriched nutrient block cultivation. The content of sodium selenite in the nutrition block is about 2 mg, which is much hig...

Abstract

The invention relates to a method for planting selenium-enriched rice by using selenium-enriched nutritional blocks. The method is characterized by comprising the following steps of soaking rice seeds into a solution of sodium selenite with the concentration being 0.04%-potassium permanganate with the concentration being 0.1% for 2 hours to 3 hours, accelerating germination according to the conventional method, sowing the germinated rice seeds into nutritional disks with nutritional soil containing sodium selenite of 100 mg / kg to 500 mg / kg, sowing 1 to 5 seeds into each block, transplanting seedlings and the nutritional blocks to a big field after seedling formation, and performing management according to the conventional method. The rice seeds soaked with the selenium solution and the selenium-enriched nutritional blocks become the selenium source of the whole growth period of the rice and can be planted in a selenium-enriched region and a selenium-lack region, selenium fertilizer does not need to be sprayed to foliage in the growth period, and the selenium content of the selenium-enriched rice is between 0.2 mg / kg and 4.12 mg / kg.

Description

technical field [0001] The invention relates to a method for planting selenium-enriched rice by using a selenium-enriched nutrient block. Background technique [0002] Rice is one of the main food crops. The total planting area in my country is about 430-440 million mu. The promotion and application of selenium-enriched rice will largely solve the problem of human selenium deficiency. Natural selenium-enriched rice is generally produced in selenium-enriched soils, but more than 70% of my country's areas are deficient in selenium, and the products cannot meet people's needs. The area of ​​selenium-enriched areas is limited, and the selenium content of products is inconsistent and unstable, making it difficult to scale. In selenium-deficient areas, selenium-rich rice is mainly enriched by soaking seeds, applying selenium fertilizers, and spraying selenium fertilizers on leaves. Uneven spraying, labor and time-consuming, etc. are the technical problems encountered in the proce...
